Intel GMA 950
The scope of this wiki is to cover in detail the Intel Graphics Media Accelerator 950 graphics processor, including driver installation and troubleshooting.
Open Source Intel Driver
Install the driver:
# pacman -S xf86-video-intel
Use gtf to generate the Xorg Modeline values and then edit /etc/X11/xorg.conf and add these values to the Monitor section, for example:
Section "Monitor" Identifier "Monitor0" VendorName "unknown" Modeline "800x600" 40.12 800 848 968 1056 600 601 605 628 #60Hz EndSection
Lastly, add the following to the "Device" section, replacing the existing Driver value if present:
VideoRam 229376 Option "CacheLines" "1980" Driver "intel"
Few additions that will speed up your card performance big time:
Add this to the driver's section in xorg.conf:
Option "MigrationHeuristic" "greedy"
And add this to /etc/profile:
Note: Setting the MigrationHeuristic option to greedy will cause system tray icon corruption in KDE 4.1, as noted here http://bugs.kde.org/show_bug.cgi?id=170283 and here http://bugs.freedesktop.org/show_bug.cgi?id=19059
