The combination of xorg-libs,xorg-server,xorg-drivers,drm, drm kernel modules, Mesa, pixman (all from git 2007-10-23) , linux kernel 2.6.22.9 and intel 965GM now works when using AccelMethod "EXA" When Using AccelMethod "XAA" the screen does not get painted like it should; it stays dark, one can see borders of windows and occasionally their contents. glxgears gets displayed correctly and causes the screen to show background, nly that it is not the background of the current X but e.g. the KDM background, which should be gone when we already entered the session. Sorry for the rather peculiar description. I am facing problems with i915GM ,please see http://bugs.freedesktop.org/show_bug.cgi?id=12795 I had try update system to Xserver 1.4 git , but so far of my test , It still valid since commit 126031655c3c1db9881ad17d712461533eb59632 on xf87-drv-intel, I don't have DRI and with latest git of drv-intel, X won't start using all parts from current git, drm loads i965_dri.so as expected now (2007-11-06) |

We are building the git versions of xorg/drm/mesa regularly, installing the drm kernel modules along with the library. When doing this lately, we get an error in the xorg log where normally the dri module would have been inserted: ========================================================================= drmOpenDevice: node name is /dev/dri/card0 drmOpenDevice: open result is 9, (OK) drmOpenByBusid: Searching for BusID pci:0000:00:02.0 drmOpenDevice: node name is /dev/dri/card0 drmOpenDevice: open result is 9, (OK) drmOpenByBusid: drmOpenMinor returns 9 drmOpenByBusid: drmGetBusid reports pci:0000:00:02.0 (EE) AIGLX error: Calling driver entry point failed(EE) AIGLX: reverting to software rendering ========================================================================= This effect does not appear on the 945GM and 965G chipsets, only on 965GM. !!!
