i migrated from xfree and actually everything runs fine. distro: gentoo desktop: gnome 2.6 driver: i810 dri: enabled nevertheless i noticed a pretty annoying problem. when i startx and switch to a console (ctrl+alt+fx) and then back to the desktop i see nothing but a black screen. the computers locked then. no mouse, no console switching no ctrl+alt+backsp. the Xorg.0.log states the following: Fatal server error: EnterVT failed for screen 0 Please consult the The X.Org Foundation support at http://wiki.X.Org for help. Please also check the log file at "/var/log/Xorg.0.log" for additional information.

Same error here, with Mandrake, kernel 2.6.9 and a i815.
(In reply to comment #1) > Same error here, with Mandrake, kernel 2.6.9 and a i815. my chipset is i815 too. I noticed that it's not a total lockup (at least not anymore). Console switching does work after some seconds and the x server crashes. Problem persists with xorg 6.8.1 and vanilla kernel 2.6.9.

Further investigations revealed that adding Option "NoAccel" "true" to xorg.conf resolves the problem which means it's a dri problem. The following dmesg output occurs when the X server crashs: [drm:i810_wait_ring] *ERROR* space: 65512 wanted 65528 [drm:i810_wait_ring] *ERROR* lockup [drm:i810_wait_ring] *ERROR* space: 65504 wanted 65528 [drm:i810_wait_ring] *ERROR* lockup And from time to time (I think it's when i'm switching consoles while the X server hangs with a black screen): [drm:i810_unlock] *ERROR* Process 6632 using kernel context 0 /var/log/Xorg.0.log contains one warning but no errors: (WW) I810(0): Bad V_BIOS checksum I'm allocating 12288KB VideoRam otherwise DRI does not work for me (at least not with 8192 or no VideoRam setting in xorg.conf). If you need further informations tell me please. Happy new year besides...
As of 6.8.1.904 the problem seems to be fixed. 6.8.2 works well too. Thank you! Can anyone confirm this?
