You are currently running the "Vesa" graphics driver, which is safe, but the slowest, ugliest, most limited driver available. Your ATI card is fully supported under the open-source driver and that's what you should be using. To configure your ATI card, do the following:
- Code: Select all
sudo modprobe -r fglrx
sudo apt-get remove xorg-driver-fglrx; sudo apt-get install libgl1-mesa-glx libgl1-mesa-dri
This will remove the proprietary ATI driver and install the open-source ATI driver. Then you have to edit xorg.conf to enable the driver:
- Code: Select all
sudo gedit /etc/X11/xorg.conf
Look in your xorg.conf for this section:
- Code: Select all
Section "Device"
Identifier "ATI Technologies Inc Radeon R250 [Mobility FireGL 9000]"
Driver "vesa"
BusID "PCI:1:0:0"
Option "UseFBDev" "true"
EndSection
Change the
"vesa" to
"radeon" and delete
Option "UseFBDev" "true" so it looks like this:
- Code: Select all
Section "Device"
Identifier "ATI Technologies Inc Radeon R250 [Mobility FireGL 9000]"
Driver "radeon"
BusID "PCI:1:0:0"
EndSection
Save the file and exit any running applications, then restart the xserver [Contrl]+[Alt]+[Backspace].
Now lets see if the changes are working:
- Code: Select all
glxinfo | grep vendor
Should show you this:
server glx vendor string: SGI
client glx vendor string: SGI
OpenGL vendor string: Tungsten Graphics, Inc.And:
- Code: Select all
glxinfo | grep "direct rendering"
Should say
direct rendering: yes.
If you get the above responses then you are running the proper open-source ATI driver and things like Beryl and Google Earth should work (if they are installed correctly).
You might also want to delete the following section from your xorg.conf:
SubSection "Display"
Depth 1
Modes "1280x1024" "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 4
Modes "1280x1024" "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 8
Modes "1280x1024" "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 15
Modes "1280x1024" "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 16
Modes "1280x1024" "1024x768" "800x600" "640x480"
EndSubSection
So that only the Depth 24 section remains and your "screen" section looks like this:
Section "Screen"
Identifier "Default Screen"
Device "ATI Technologies Inc Radeon R250 [Mobility FireGL 9000]"
Monitor "17LCDMONITO"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1280x1024" "1024x768" "800x600" "640x480"
EndSubSection
EndSection
Note that any changes to the xorg.conf file require restarting the xserver before they will take affect.
Good luck!
