Bug Description

Binary package hint: xserver-xorg-video-ati


I just upgrade my thinkpad t42 on jaunty and i have this problem. The 2D acceleration is slow with EXA, especially with gecko application like firefox or gnome-system-monitor. For exemple, if you reduce the firefox windows, the desktop icon often take several second to refresh, or moving the gnome-system-monitor windows on the desktop is very slow. The other application like nautilus are less problematic,but i feel that they draw slower.

-The fact to go back to XAA with the option 'Option "AccelMethod" "XAA"' solve the probleme.
-The problem seems to go with "DefaultDepth 16"(maybe a problem my 32mB of ram)

have a nice day

I will add a me-too on this one. System was fine on intrepid.

The only difference is that my card is a:

   01:00.0 VGA compatible controller: ATI Technologies Inc RV350 [Mobility Radeon 9600 M10]

I made these changes to xorg.conf

   Option "XAANoOffscreenPixmaps" "true"
   Option "ColorTiling" "on"
   Option "EnableDepthMoves" "yes"
   Option "EnablePageFlip" "yes"
   Option "AccelMethod" "XAA"

And all is now back to how things were in Jaunty from what I can tell using gtkperf
