I switched from i810 driver to intel (xserver-xorg-video-intel 1.6.0-0ubuntu1) driver and got my 1024x768 back with xv, DRI and AIGLX.
Altrough intel driver has some issues: DRI is slooow (max 600fps in glxgears, max 500fps w/o DRI = +100fps only); I can not switch to console (consoles content is in upper grabbled 2 cm of screen); fn key to switch between LFP and VGA out doesn't work; TV-out also doesn't work (have not tested with i810); some hard-lockups on high load. But still is better than VESA :) -- 640x480 with i855gm in edgy, OK in dapper https://launchpad.net/bugs/61234 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
