[arch-general] Radeonhd - Use EXA Accel instead of XAA Accel
Listmates, If you use the radeonhd driver, use EXA acceleration instead of XAA. I just found out about this today and it is a 100% improvement in speed, etc. over XAA acceleration. It isn't as fast as fglrx, but it is a world of improvement over the alternative. To make use of EXA acceleration, simply enable it in your xorg.conf in the device section. Example: Section "Device" BoardName "RS690M" Driver "radeonhd" Identifier "Device[0]" Option "GARTSize" "256" Option "AccelMethod" "EXA" Option "EnablePrivateBackZ" "no" Option "VideoOverlay" "on" Option "no_dri" "no" Option "UseFastTLS" "1" Option "no_accel" "no" Option "mtrr" "off" VendorName "ATI" EndSection -- David C.

Interesting. I've got a Radeon: # lspci | grep -i vga 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon HD 3870 And when I define EXA or XAA I get a whole bunch of problems, specially scrolling or when I jump from one tab to another in say, Konqueror and/or Firefox. Commented out the Accel options in xorg.conf and now it works nice. # pacman -Q | grep -iE "(radeon|xorg-server|xorg-utils)" xf86-video-radeonhd 1.2.5-1 xorg-server 1.6.1-1 xorg-server-utils 7.4-6 xorg-utils 7.4-4 Rafa -- "We cannot treat computers as Humans.
