^this drives me crazy

We should really make a Linux Q&A thread

For those looking for the solution to this; I gave it to this member via PM due to my work computer being crap and not having an up-to-date web browser (I cannot do anything about this) the quick 'n dirty is this:

Pacman relies on PGP signatures for package verification - this ensures the package you are installing is indeed the one the package maintainers intended you to receive. Sometimes, during installation - due to any number of various issues - the keyring fails to generate properly; if you run into a bunch of key errors like the above user had; try this:
Code:
#pacman-key --init
#pacman-key --populate archlinux

The first command above will initialize the keyring with a local signature, this signature is generated using whole-system live entropy which is pretty much as secure as you can get in the computing world. While you are waiting for it to finish executing, browse the web, listen to music, watch some videos, type and move your mouse - the more you are doing, the quicker it goes - and the less likely it is that someone could ever replicate the exact conditions under which your key was generated.
The second command grabs all of the core Archlinux developer keys from a key server. If this command fails to connect to the server - your country could be blocking the key server in question - if this happens - try changing the keyserver line in /etc/pacman.d/gnupg/gpg.conf to:
Code:
keyserver hkp://pgp.mit.edu:11371

This should clear any issues with package verification up permanently; if issues arise again, the steps can be repeated to fix them again, though it is highly unlikely.

So first day of my Linux class, anyways I have a question I didn't see in the Q&A

I want to build a Linux Machine, that can emuLate windows on the fly, for gaming mostly.

Or rather, I'd like a Linux machine, but I want on the fly support for my windows applications, such as Gaming. Any tips

and I'm talking software atm, hoping to find what software I need now, so I can get the appropriate hardware in the Fall of this year
http://pcpartpicker.com/p/2B6XJ
I'm hoping that build will be sufficent, I'll have dual monitors on it, and a few more fans that are in my current build

but any tips :3

Install PlayOnLinux and have fun tongue.gif

Of course, keep in mind that gaming through Wine is never an absolute, and will require some tinkering from time to time. If your sole purpose is gaming I'd stick with Windows for the time being and just dual boot into Linux.

( that being if your intended games aren't Linux capable at least )

In addition to PlayOnLinux, there is Crossover. It isn't free, but I've heard it's great software for the money. When you get more comfortable with the command line you can try setting up wineprefixes. Many games will run unmodified through Wine, and most will with the right settings.

As for the build, it looks pretty solid. The AMD GPU isn't as well supported as Nvidia GPUs at the moment though. By the fall, that could change. It looks like AMD is trying to get their drivers into shape for SteamOS.

I've been lurking the Linux gaming virtual machine thread for...pretty much as long as it has existed really. Looks like a lot of work...or adventure...but at least you'll come out the other side with a lot of knowledge/experience...

Plan for the build is around Fall of this year, by then it should be cheaper to build than it is now, and better supported.

I'm not a fan of nVida prices or GPUs in general. I live in the South and I've found AMD runs cooler which I need as it's about 80+ degrees in my house for 3/4 of the year

regardless, thanks :3

any one know of... some kind of Windows Software Emulated version of Linux? Something that will let me goof around in the Shell so I can at least learn it before the build

I am also going to attempt today to get a USB or CD boot of Linux on my Windows 8 Machine, any one know how to change the boot order for Windows 8?

There's Linux / GNU / POSIX tools for Windows which aren't emulators. cygwin or mingw are the big two, personally I'd recommend mingw out of those two.

You could also go fully virtual and install Linux in a virtual machine using either VMWare Player or VirtualBox (both of which are free).

not sure I have the resorces to run VM ware on my dinky lap top, it's got an i3 and like 4gbs of ram I think but... it's not that great imo... I think booting from USB might be a good idea

but I can find my specs [or run a 3D Mark bench for u guys] and if Ive got the POWER to run vmWare Linux I'll go that way.

I've only got one small screen on the laptop so vM might be a good idea, if windows 8 will let me move it like it does other applications

let me know though if u want my specs or the 3D mark bench biggrin.gif [ I kinda wanna do the bench xD]
