LINUX for BOINC - HOW TO INSTALL IT WITH NVIDIA GRAPHIC CARDS

(Assumes you know something about computers and you are running Windows XP or Windows 7 and have Nvidia CUDA capable cards, AND A 64 Bit Capable CPU and you want a GUI desktop.)

Okay folks, late but here. Crappy Pictures do to sync aliasing, but they help explain the instructions. I will try to get improved pictures later. I SUGGEST YOU READ THROUGH THIS WHOLE PROCEDURE UNTIL YOU ARE SATISFIED YOU HAVE A GOOD HANDLE ON THINGS!

For now, here is what I have learned and I am by no means an expert... but Linux can be a major pain if you try to install it on a system with Nvidia cards!

THERE ARE A BUNCH OF ALTERNATIVE WAYS TO DO ALL THIS. I THINK THIS IS DADGUM SIMPLE, MINIMUM HEADACHE WAY!

Why Linux? Because my friends, for two main reasons.

1) Many Alpha and Beta projects have tasks that only run on Linux, like "Optima@Home".
2) Because some of us have dedicated crunching machines, even crunch farms, and who wants to pay for a legal copy of MicroCrap Bloatware for each one? Linux is FREE!



I am using WEEKS of experience trying every major brand to help ya'll do it fast and easy and correctly first time.

Follow my method and you will probably be up and running first shot... otherwise, you're on your own and probably be screaming bloody murder hating Linux and surfing all the Linux info for days or more (like I already have).

So, in a nutshell, this is how I do it, step by step. I did it again today and it worked first shot. Keep in mind the goal is to get a working and stable system that crunches well. NO OTHER considerations... the drivers must work with BOINC... that's it. Anything else, don't care.

I have tried the following flavors of Linux with the following results on three (3) desktop systems with Nvidia cards:

Ubuntu 10.04 LTS 32b and 64b - Doesn't Work (32b works on my laptop without a GPU)
KUbuntu 10.04 LTS 32b and 64b - Doesn't Work
LUbuntu 10.04 LTS 32b and 64b - Doesn't Work
Debian (new and old) 32b and 64b - Sorta almost works, for experts only and that ain't me. Real pain for novice.
Puppy Linux 32b - Doesn't work.
Ubuntu 11.04 32b - Doesn't work (32b works on my laptop without a GPU)
(and a couple others I can't remember the names of... didn't work)

Ubuntu 11.04 64b - Works without fail on all three systems with todays version and all updates!!!

So, I guess the rule is, install Ubuntu 11.04 64b my way or struggle along on your own. Fact is, it works this way on 2 AMD and 1 Intel system flawlessly with Nvidia GPU's. That includes the 9800 GT, GTX460 OC, and GTX 560 Ti SC flavors of graphic cards. All work fine!


Phase 1 - Make a Disk

1) DOWNLOAD Ubuntu 11.04 64b ISO image HERE: http://www.ubuntu.com/download/ubuntu/download


QMEAb.jpg


1a) If you need a CD/DVD burning program to burn the ISO image, get it HERE: http://cdburnerxp.se/


2) Burn the ISO image onto a CD or DVD. It will look like this when done:


sHmGF.jpg


Phase 2 - Prepare Partitions

You can install Ubuntu "along side windows" and that gets you a buried system on your Windows boot disk. It works, but it's not ideal. Do it that way, you're on your own.

You can use three (3) other methods which I prefer (and have done!) with perfect success... but let me warn you now about something:

Linux will install GRUB2 boot manager on whatever hard disk (SSD) you have that boots windows.

The only way you can uninstall it is to uninstall Linux. But, if you have a crash, then it's a bit tedious to get rid of it.

So, decide now if you want dual-boot or separate system disk for Linux. Linux uses so little memory, it can run off a USB 12g stick, so any little tiny HD you have would work fine. Remember, this is a BOINC machine, nothing else is considered. (Umm, 12Gig isn't enough for BOINC though...but it's enough for just Linux)

Also, any way you choose to do it, Linux runs best (and demands) a SWAP drive; I recommend a SWAP partition of at least the size of your RAM... but it will work with a smaller one down to 2gig or so. (all I have tested so far) It's best to use a swap partition at least the size of your RAM because Linux handles and uses virtual memory differently than windows and actually seems to use it without thrashing badly!

Method-1: Totally separate Install on Single Drive

If you want a totally separate Disk-Swap sort of installation, first REMOVE your windows system drive and install whatever other drive you want by itself. Linux and Swap will be on this one single drive.

Method-2: Multiple Drives, Separate Partitions with Windows and separate Swap Install

This method puts Windows on the first partition, Linux on the second, Windows Data on a separate drive and Linux swap on that separate drive. GRUB will be installed and EXPECTS windows partition to always be there! If it ain't, your system will trash. (Been there, done that too... sheesh)


Method-3: Single drive, Separate Partitions with Windows and Swap Install

This method puts Windows, Linux, Data, Swap on four (4) separate partitions on ONE drive.

Okay, pick your poison... Pick your partition tool/method and here is what it will look like:

Method 1 with stand-alone hard disk, no windows:

Partition a drive with one 30Gig (or more) primary partition and a second SWAP drive partition (8-24Gig is fine). I call mine Linux-Boot and Linux-Swap. No picture for this, it's too dang simple. You can partition a BLANK drive with the Ubuntu install, but I don't show that method because all my systems are Dual-Boot.

Method 2 with two separate drives, Windows already installed:

You can Shrink an existing Windows Partition 30Gig and use that as your Linux Root (main) partition using Disk Manager or whatever. With Partition Wizard Pro you can do it easy and pre-format it to use Ext4 instead of NTFS, but it isn't necessary since Ubuntu can format it that way as well. In the following picture, I have two partions on a 64Gig SSD and I shrunk a 12 Gig swap partition on my Data Drive.

YqbQx.jpg


Method 3 Windows & Linux & Data & Swap on ONE Drive:

In this picture, I popped out one of my crunching machine drives to show you how it is setup. It's a 2.5" WD 500 Gig (massive wasted unused space) drive with everything on it... Windows, Linux, Data, Swap... all on one drive.

r8sVq.jpg


Once you decide what method you will use, try to get the partitions setup BEFORE you start the install.

This install tutorial DOES NOT SHOW partitioning and presumes they are already there.

REMEMBER, drives with the standard MBR only support a maximum of 4 partitions on any single physical drive! Don't try this on a drive that already has more than two partitions on it without great care!

!!WARNING!!

IF you choose method 2 or 3 and create partitions for Linux-Root (main) and Linux-Swap, DO NOT FORMAT THEM unless you can do it with something other than NTFS! The reason is, during the install, Linux uses nomenclature you may not be familiar with. Drives aren't C,D,E and such, they are /dev/sda and under that can be like /dev/sda1 or /dev/sda5 etc... !!!!

If you do not format them and just create the partition bare, then it will be easier for you to install Linux in the correct spot and not accidently clobber your windows install! (yea, I done it once already).

If you choose to format them ahead of time, format them with Ext4 file system so it's perfectly clear what is what during the install!

And, if you can, to be 100% safe, CLONE your original drive before doing any of this just in case you clobber everything for one reason or another. BACKUP EVERYTHING ON A SEPARATE drive and keep it safe!!! Do a clone or Mirror image... something!

You never know if some driver bug is lurking somewhere in Linux that doesn't work with your hardware. BE WARNED! HAVE a complete backup saved before going any further!! It is very easy to screw up ALL the drives in your system during the initial install!

I use "Acronis" for cloning and some backups. Pretty much, I bought it for the disk "clone" feature. There are others out there I'm sure. As in all things, pick your poison...

Phase 3 - Ready, Set, GO!!

Okay all you overclockers pushing your systems to the max, hear this. If there is the slightest chance that one bit will go wrong in this install because you have pushed the envelope, PLEASE PLEASE set your system back to default speeds for this installation. Linux is a whole different animal, it ain't windows like in any way. Be nice to yourself and install this with 1000% reliable settings. If you don't, I don't want to hear about any problems you have because it's a waste of time with the only correction method being to start over from scratch.

Having said that, I will presume you have your Linux system install CD/DVD in hand, your system partitions already created (for methods 2/3) and are ready to go.

Step-1: Turn on System, install boot CD you made in CD/DVD reader.

Do whatever you have to do to start your system off the boot CD. On my Asus boards, I hit F8 to bring up the boot selection menu because my main drives are first in priority, not the CD/DVD drive.

If you have multiple monitors, the install will most likely duplicate the picture on 2 main monitors if they are on the same card. That doesn't mean you have to do everything twice, just that the other monitor is watching to see if you screw up. smile.gif

j3tlH.jpg

Step-2: Watch the screen, prepare to type and mouse click.

If everything works right, Ubuntu will load off the CD and eventually present you with the install menu:

This should be the first thing you see... (no shutting eyes, have to watch!)

k3rtz.jpg

Pretty isn't it! smile.gif The color dots blinky on off and such... very pleasing to the eye.

Eventually you get to the start menu screen, now we're cook'n!

SELECT "INSTALL UBUNTU" (with language of your choice)

vkHPN.jpg

Next we get the first option screen.

SELECT "Download updates while installing"

If you don't, you'll be sorry and have to start over again. smile.gif

NOTICE it isn't "Next", it's "FORWARD"! (Click that!) Your first taste of Linux!

KXEZp.jpg


SELECT The First ROOT (main) Partition! BE CAREFUL!"

You have already partitioned your drive one way or another, now be careful! Make sure you pick the CORRECT drive for the ROOT area. In this picture, notice the selected partition is already formated Ext4 and it's 30458Meg (30Gig) in size. I know this is the proper partition, but Linux calls it /dev/sda5 for whatever reason. YOUR DRIVE MAY BE DIFFERENT like /dev/sda3 or something! GO by the SIZE and FORMAT (or lack thereof)!!

wYZtV.jpg

If you are certain you have the correct partition selected, then:
CLICK "CHANGE"

An "Edit Partition" popup appears....


xmBd6.jpg


SELECT "Use as: Ext4 journaling file system"

ry1qm.jpg

SELECT "Mount Point: /"
SELECT "Format the partition: (box)" if it needs it.
CLICK "OK"

Should look like this when done:

zsjlA.jpg


SELECT The SWAP Partition! BE CAREFUL!"

If you are certain you have the correct partition selected for SWAP, then:

CLICK "CHANGE"

bw0Nf.jpg

SELECT "Use as: swap area"
CLICK "OK"

This swap was 12Gig large, equals the ram on my system. Should look like this when done:

f8cUR.jpg


CHECK ALL OTHER PARTITIONS! BE CAREFUL!"


Best to click on any/all other partitions and make sure they are set to "Use as: do not use the partition".

w5TZ1.jpg


If you are certain you have it right, then CLICK "Install Now" and you are on your way...

If you messed up, you could have just clobbered your Windows install... sorry about that... done it myself and pizz me off! LOL! biggrin.gif

Now, almost time to relax for an hour or so while the whole initial install process completes. It's almost break time!! It has a ton of stuff to download, give it time... takes a while...

But first, go to next post! We have a couple more things to do...

During the install, you will first be presented with this:

DO NOT IMPORT ANYTHING! CLICK "FORWARD"!

MYPvW.jpg


Yes, Linux multitasks well even during the install! Okay, we are really close to break time...

WHO ARE YOU?

Well, I installed it on the i7-950 system, and I am the owner... so fill in the blanks.

SELECT "Require my password to log in" or you will be sorry later...

I suggest one keeps the password short and simple. The 950 system password is "950". LOL! smile.gif


CLICK "FORWARD" when done.

v7Yyq.jpg


Keyboard layout


Self explanatory I think... I use USA USA keyboard...


CLICK "FORWARD" when done.


DpvxU.jpg


Where are you?


Pick your time zone, CLICK "FORWARD" when done.


01zPI.jpg


Welcome to Ubuntu

HuWFx.jpg


Okay, now it's Miller Time!!! Take your 1 hour break or whatever... Click on the arrows to read the blurbs about how easy it is to use and such... LOL!

=================================================

Watch the screen... When the initial install is complete, it will tell you it needs to restart.

Ip5Re.jpg


Be prepared for your first glitch. The install drivers are not perfect and sometimes the screen blanks, things stop working and nothing else happens... or maybe the CD ejects, blanks screen, then nothing.

YOU MAY HAVE TO PRESS AND HOLD THE POWER-ON BUTTON TO MANUALLY SHUT DOWN AFTER THE INITIAL INSTALL!

This is normal, it should not happen again... (knock on wood) smile.gif

I have my own ideas of what I like and I will share them with you. Feel free to change the appearance and play around with Linux "AFTER" you are done with this method. Things I show for appearances sake can all be changed, but it aids in the install using my technique and preferences.

Okay, I have to mention that often a little popup window appears and says you need to authenticate some action with your password. It's the same password you use to log in...

After the install is complete and the system starts to reboot, you should be presented with a GRUB (GRand Unified Bootloader) selection screen:

If you do nothing, it will start by itself after some seconds. Here you can see the different options including Windows 7 on the bottom.

SELECT "Ubuntu with Linux 2.6.38-xxxwhatever" and hit ENTER.

RFKpn.jpg


Next we get the login screen.

When you get to the login screen, CLICK the NAME (owner in this case) but DO NOT ENTER THE PASSWORD YET!

Next, LOOK CLOSELY AT THE BOTTOM BAR!!!

eZk1r.jpg


You will see several "login options" there after you click your name...

CLICK the double arrow on the right.

It will bring up a selection menu....

UrN2B.jpg


SELECT "Ubuntu Classic (No effects)"

0LbV7.jpg

That will get rid of "UNITY" overlay and leave you with the straight GNOME desktop. Go ahead and enter your password and log into the system now.

********************************************

"UNITY" overlays on top of "GNOME" desktop... this is the new widget thing on the left... a place to put large icons and a stupid application interface that is somebodies idea of good.
Well, it stinks, it won't work with certain Nvidia display modes and adds no value to a crunching machine. ( All Facts & MY OPINION )

It looks like this:

b6Ocv.jpg

We are NOT going to ever use it, but I wanted you to see what you are missing. It's junk and causes problems.

********************************************


Now, let's make sure we install(ed) all the latest stuff.

CLICK on the "SYSTEM" icon TOP-RIGHT and SELECT "System Settings"

4H4ak.jpg
rbuW4.jpg

The big "Control Center" window with everything in there should appear....

SELECT "Update Manager"

You may have to scroll down to see it! There's an orangeish scroll bar on the right edge of the window... takes some getting used to... or use your mouse wheel to scroll around...

CyFQv.jpg

The "Update Manager" should appear and it might look like this if all the updates were installed already:

77ffl.jpg

If the Update Manager shows "Your system is up-to-date", then you can skip the next part.

If the "Update Manager" looks like this, then CLICK "Install Updates" and enter your password, then sit back and relax a while.

VUm4m.jpg
weXYX.jpg

When it is finished installing all the updates, CLICK on the "SYSTEM" icon TOP-RIGHT and SELECT "Restart".

{REBOOTING......}

Repeat the above "Update Manager" check until there are no more updates to do.


Next thing to do is get rid of the bottom useless toolbar.

RIGHT CLICK on the lower toolbar (panel in Linux).

A little menu appears.

8RjDs.jpg

SELECT "Delete This Panel"

IK9rg.jpg

Blip! Useless panel (toolbar) all gone!

RIGHT CLICK on the upper panel.

Another little menu appears.

SELECT "Properties"

C7uvT.jpg

A little "Panel Properties" for that panel appears...

SELECT "Orientation: Bottom"

a6W7p.jpg

BLIP! The panel drops, menu still there!

Now, IF you have a larger High Resolution monitor then:

SELECT "Size: 48 pixels"

(Or whatever sorta looks good on your system, but make it a bit larger...)

m4vnm.jpg

You should end up with a bottom panel (toolbar) that looks about like this:

TBhVb.jpg

Notice the Firefox icon already in place? Nice of them! Ignore it... not part of this install. Next we pretty things up a bit...

SELECT and CLICK "System/Preferences/Appearance"

A "Theme" tab will appear in the "Appearance Preferences" window that pops up.

GEi2R.jpg


SELECT "Clearlooks" then CLICK the "Fonts" tab and Select your rendering preference; then "CLOSE"

kajza.jpg
SKRZ1.jpg

Now we have something that looks a smiggen, just a tiny bit like the windows interface we all love so much... hmmph...

By default, the installer is the Administrator... you have the POWER! Bwaahahahaha!!! tongue.gif

Anyways, let's proceed to the final install tweaks. We are going to install BOINC and XSensors and 32bit support files. We will put a few nifty "Quick Launch" icons on the bottom panel that are useful too.

Then, I will show you how BOINC doesn't work, then we will fix it.

So, without further delay, let's do it! (and be glad we are almost done!)

SELECT "System/Administration/Synaptic Package Manager"

c3icg.jpg

Woopsy! There is that admin popup!!

ENTER PASSWORD then CLICK OK

OciPg.jpg


===============================================================
The Synaptic Package Manager is a nifty little thing that manages application installs/removes and does it cleanly with little fuss. It's one of your best friends with this version of Linux!! Get to know it! Ubuntu and others all provide "packages" of all inclusive Applications and Tools and Whatever that will run on your system. Should one decide to play around with different things, my recommendation is use this manager to install/remove as many things as you can. The "non-GUI" method of installing and removing applications/tools/libraries (and maybe having to know ahead of time what all the dependencies are) using the terminal method is a PITA sometimes! (especially with revision changes and such). With Linux, what works on one revision may not work on a newer revision without additional downloads... Synaptic Package Manager takes care of all that for you as we will see.

But remember, this install is for a dedicated BOINC cruncher with Nvidia GPU's only... anything beyond that, have fun and you're on your own! smile.gif

===============================================================

Okay, we have this Package Manager up now. We are going to install three (3) packages that are required for successful BOINC operation.

1) 32 bit support libraries
2) Sensor widget to monitor things
3) BOINC

Yup, getting close to done now.

In the Synaptic Package Manager TYPE "boinc" in the "Quick Filter" box

TWRoS.jpg

A list will appear of things "boinc" related.

SELECT the 6.10.59 (or latest) metapackage and CLICK little box on left and SELECT "Mark for installation".

WFa5M.jpg

Another popup appears showing all the stuff that will be installed.

To expand the list, CLICK on that black arrow thingy left of "To be installed"

3YbEV.jpg

The list will expand showing everything...

CLICK "Mark"


TYPE "xsensors" in the "Quick Filter" box

Fuqoi.jpg

SELECT "xsensors" and CLICK "Mark for installation" then CLICK "MARK" as before.


TYPE "ia32" in the "Quick Filter" box

3IZmP.jpg

SELECT the "ia32 shared libraries..." and CLICK "Mark for installation" then CLICK "MARK" again.

Pheweee! Now all three packages we need are setup to install. Remember, the Synaptic Package Manager presents a list of everything it knows about; that is why you have to search that huge big list to find anything! LOL!

On the top bar of the Package Manager, CLICK "Apply"

w8mUe.jpg

Another "Summary" popup will appear, CLICK "Apply".

zKDqU.jpg

"Applying Changes"... First it downloads stuff... then it installs all the stuff.... just let it install everything.

17KRM.jpg
KcVgO.jpg

When it is all done, CLOSE the package manager and any other windows.

Go to the RIGHT-BOTTON panel (toolbar) CLICK on the square SYSTEM icon, SELECT "RESTART".

7cJFT.jpg

REBOOT INTO Linux again

Should come up just fine, LOGIN to the system again...

Don't worry if your multi-monitor rebooted system looks like this: (we will fix it next)

Nice I will need this to get all my old rigs up and running for BGB:D
post #8 of 44
Thread Starter 
To recap, we now have a basic GUI Desktop, BOINC, XSensors, and all the libraries and such installed. But, we now need to make two things work (The Display Driver and BOINC) because right now in all probabilty they don't!

Keep in mind what monitor/display setup you are going to use (if any).

Ignore the fact this install shows a setup for four (4) monitors on dual video cards if it doesn't apply to you.

However, I will show the four monitor setup LATER in case it's useful to someone... like after I'm done with everything else.

If you have only one monitor, the more complicated setup for multiple monitors can be skipped. Or, if your graphics card only drives one monitor, again you can skip the multi-monitor thing.

First, let's continue a bit with the desktop and put some useful icons on the lower panel (toolbar)

SELECT Applications/System Tools AND HOVER over the "BOINC Manager" or "XSensors" item. RIGHT-CLICK on either one and SELECT "Add this launcher to panel".

2uZ2D.jpg

RINSE AND REPEAT so both BOINC and XSensors icons are on the panel.

T018o.jpg

DRAG the icon(s) where you like. If it won't drag, it's locked! (like the Firefox icon)

RIGHT-CLICK on the Firefox icon! Unlock it!

When you have the icons where you like, lock them again...

Let's get the Nvidia Driver setup correctly

Now it time to fix the Nvidia install. It's almost good, but not perfect. First, let's make sure it's there!

SELECT System/Aministration/Additional Drivers.

eEfvB.jpg

It should pop up a window that looks like one of these two:

ZNCRW.jpg
lDtuW.jpg

BUG! If the "Nvidia accelerated graphics driver" is in the top display with a "GREEN" light on the left (as in first picture), then it is already installed and working. BUT, the messages on the top & bottom say it's not currently in use! That is an error! Ignore it!

If the "Additional Drivers" shows two options on top (second picture) and isn't GREEN lit, then SELECT the "Nvidia accelerated graphics driver" and CLICK "Activate", then "Authenticate" as usual.

It will start downloading and install.

NHIv1.jpg


After the install is complete, CLICK on the "System" icon on the BOTTOM-RIGHT of the panel and SELECT "Restart..."

ePqHY.jpg

{REBOOTING, LOGIN again}


Okay, back into the system with the drivers all installed... finally tweak the Nvidia driver...

SELECT System/Aministration/NVIDIA X Server Settings

xqd13.jpg


The "NVIDIA X Server Settings" window appears.

BxalD.jpg

SELECT "X Server Display Configuration" on the left panel.


6jg1w.jpg

Notice only one monitor of four is shown active. THAT IS FINE for now! If you only have one monitor, that is all you will see anyway!

++++++++++++++++++++++++++++++++++++++

IF you have a PNP monitor and a modernish Nvidia card, the display resolutions and refresh rate should default to optimum. IF you need to change the resolution and/or refresh rate, do it now. It's easy clicky stuff...

++++++++++++++++++++++++++++++++++++++


When you are finished, CLICK "Save to X Configuration File" button on lower-right side:

wrT8n.jpg

Probably get a "Failed to parse..." message, IGNORE it and CLICK OK

TOIGx.jpg

Then it will popup a "Save X Configuration" box, MAKE SURE the "Merge with existing file" is NOT CHECKED! CLICK "Save"

h5pCw.jpg

Then a pesky "Authenticate" thing, ENTER your password and CLICK "Authenticate"

Meng9.jpg

Close ("QUIT") the NVIDIA X Server Settings window, then CLICK on the "System" icon on the BOTTOM-RIGHT of the panel and SELECT "Restart..."

ePqHY.jpg

{REBOOTING, LOGIN again}

At this point, the Nvidia drivers and the basic system should all function properly now... we hope.

ONE last thing to do... we have to fix BOINC.


CLICK the BOINC icon on the bottom panel...

CJfiz.jpg

"CANCEL" the "Attach to project" popup and SELECT "Advanced View".

ilrQs.jpg

SELECT the "Messages" tab... see the problem?

2WGP1.jpg

XX% of folks (a lot!) installing this on higher performance systems will see the "No usable GPUs found" glitch in the messages window. If in your case it shows usable GPU's, still I strongly suggest following the correction method.

++++++++++++++++++++++++++++++++++++++

IF YOU DON'T have a "CUDA Capable" graphics card, then you are only going to be crunching CPU tasks anyway. So, you are all done now, no need to apply the following fix. BUT, if you ever plan to upgrade, best to put the following fix in place now anyway. This is the last tweak we do...

++++++++++++++++++++++++++++++++++++++


The reason BOINC doesn't see the GPU's is because Linux loads things so fast that the "GRAPHICS" driver (X Windows Server) isn't fully initialized before BOINC is started.

WHAT? BOINC was already started? YESSSS!!! Unless you go through some loops, BOINC installs as a service that starts automatically when Linux boots. It's ALWAYS running! Well, that is fine with me, that's what the machines do... run BOINC!

The way we fix this timing problem is to put a delay in the startup BOINC script.
The required delay varies... anything from 4 to 10 seconds depending on how fast the boot disk and system speed are. So, to cover all the bases, we will set a 10 second BOINC startup delay. My i7-950 with SSD boot drive starts so fast, that even 8 seconds isn't long enough, but 10 seconds works. Your system may be different... you can reduce the delay if you want to test, but who cares? It's a dedicated Linux machine crunching BOINC...

CLOSE the BOINC Manager...

LAST TWEAK, here we go!!!

(Deep breath, sip coffee, almost done...)

SELECT Applications/Accessories/Terminal

cRHG9.jpg

A Terminal Window should appear...

TYPE "sudo gedit /etc/init.d/boinc-client" ENTER

TYPE your PASSWORD, (it will NOT echo anything!) ENTER

4Klss.jpg

A "Gedit" window should appear... with the contents of the BOINC-CLIENT startup script inside. If not, something messed up badly...

d2kJW.jpg

SCROLL DOWN A WAYS, FIND THE "start()" entry.

After the "else" clause, hit ENTER, use space-bar to move right (not tabs!) and TYPE "sleep 10"

Zffou.jpg

CLICK "Save"

vS1AR.jpg

CLOSE the Gedit and Terminal windows.


CLICK on the "System" icon on the BOTTOM-RIGHT of the panel and SELECT "Restart..."

ePqHY.jpg

{REBOOTING, LOGIN again}

CLICK the BOINC icon on the bottom panel...

CJfiz.jpg

"CANCEL" the "Attach to project" popup and SELECT "Advanced View" if needs be.

ilrQs.jpg

SELECT the "Messages" tab... see the problem fixed? I sure hope so!

EuQK4.jpg

IF the "No usable GPU's found" problem is gone, then you are ready to attach to projects and go crunching! Congrats!

IF the "No usable GPU's found" problem still exists, then only one of two things is probable...

1) YOU DON'T HAVE a usable GPU!!!!

2) Something is screwed up beyond my limited experience!!!!!



IN ANY CASE, this beginners tutorial is now done (for the time being)... I will add the mult-monitor setup and some other advice later after I move...
