The laptop I am running now (Sig Rig) had Ubuntu 8.04 on it, I upgraded to 8.10 and now the Display is stuck at 800x600 instead of 1024x768, and its stuck in low Graphics Mode or something, its hard to find drivers for the chip, since it seems it was ONLY in the brand of laptop I have, anyone care to offer some help? I don't care too much about 3D stuff, just making sure its in normal VGA mode.

Okay, I made it go into normal 3D mode, etc.

Now I just need the resolution fix (Getting it to show 1024x768 as well as 800x600, instead of just the first two.)

Have you tried using the open source drivers?

- Rebuild X (so you start fresh):

Code:

Code:

sudo dpkg-reconfigure xserver-xorg

- Open xorg.conf for editing:

Code:

Code:

sudo gedit /etc/X11/xorg.conf

- Add the following lines to the "Device" section:

Code:

Code:

Driver   "ati"
Option  "AccelMethod"   "EXA"

- Save the file and reboot.

The chip should be supported by that driver. Only opengl1.3 and half the speed of the regular ATI driver, but with that IGP you don't really need 3D muscle (it should still be able to run Compiz at minimum and KDE4 effects thought).

Yeah, I found that, it also said to add a few other things.

I need to find a way to let me put the Resolution up to 1024x768 now.

You can try adding the resolutions to your xorg.conf:

Ex.

Code:

Code:

Section "Screen"
        Identifier      "Default Screen"
        Device          "Radeon 9600"
        Monitor         "Generic Monitor"
        DefaultDepth    24
        SubSection "Display"
                Depth           24
                Modes           "1440x900" "1024x768"
        EndSubSection
EndSection

Code:

Section "Device"
    Identifier    "Configured Video Device"
    Driver        "ati"
    Option        "AccelMethod"            "EXA"
EndSection

Section "Monitor"
    Identifier    "Configured Monitor"
EndSection

Section "Screen"
    Identifier    "Default Screen"
    Monitor        "Configured Monitor"
    Device        "Configured Video Device"
    DefaultDepth    24
        SubSection "Display"
                Depth           24
                Modes          "1024x768" "800x600
        EndSubSection

Remember that you need to at least restart X (ctrl+alt+backspace) for changes to have effect. If not, you could still try the regular ATI driver:

- Install dependencies:

Code:

Code:

sudo apt-get install build-essential cdbs fakeroot dh-make debhelper debconf libstdc++5 dkms

- Download the 9.2 driver from ATI's website. Travel to were you downloaded the driver to:

Code:

Code:

cd /<location of driver>

- Run the installer:

Code:

Code:

sudo sh ati*.run

- Use the default settings and let it finish. After it goes through installation it will drop you to the terminal; make sure no errors were given and initialize the module:

Code:

Code:

sudo aticonfig --initial

- Reboot

This isn't put in the normal ATI driver for some reason..

I copy pasted that and still got a display error on start up, yes I have been saving and rebooting every time I edit something.

You don't need to reboot when editing xorg.conf just do ctrl-alt-backspace to restart X.

ctl-alt-backspace kills X, it doesn't restart it. If you have gdm configured (I make it a point not to) then gdm will catch it and restart.
