[ 15.259] (EE) intel(0): [drm] Failed to detect GEM. Kernel 2.6.28 required. [ 15.260] (EE) intel(0): Failed to become DRM master.

This is weird. Sure, that the i915 kernel module can still be loaded? Please boot with boot options "drm.debug=0x4 3" and attach the output of 'dmesg'. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

/var/log/messages has: Jul 19 20:17:57 cedar xdm[538]: Starting service kdm..done Jul 19 20:17:57 cedar kdm_config[654]: Cannot open master configuration file /var/adm/kdm/kdmrc.sysconfig Jul 19 20:17:57 cedar network[449]: Setting up (localfs) network interfaces: Jul 19 20:17:57 cedar acpid: 1 client rule loaded Jul 19 20:17:57 cedar kdm[653]: X server died during startup Jul 19 20:17:57 cedar kdm[653]: X server for display :0 cannot be started, session disabled

I'm running on a 32 bit system, with a N2800 Intel atom, with the infamous GMA3600 series video card (Cedar Trail). If the 'cedar' above refers to Cedar Trail it might be it. Intel has failed to provide an apropriate driver for Linux. After exactly the same update I have experienced the same issue, before that the gma500 module provided a basic functionality, not i915. I suspect the xf86-video-intel update might be related, but I don't know, it can be a different thing. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Fortunately both src.rpms (2.19 and 2.20) are available at: http://download.opensuse.org/update/12.2/src/ I made a diff between, you can find it attached. It is not just a small patch, but a rather big file (over 30.000 lines!). The change notes starts with: Release 2.12.0 (2012-07-15) =========================== First the big news, a new acceleration method that aims to be faster and consume far less CPU than UXA is now available for selection at runtime. This snazzy new architecture can be selected through use of Option "AccelMethod" "sna" in your xorg.conf. Whilst it has been under development for some time, it has not yet had the same degree of widespread testing of UXA, so tread lightly. Try it and if you spot anything that can be improved, please do report a bug. <<<< >>>>> Thus it is not a trivial update, but introduces a new feature. ps: the version number is first line is wrong. It states 2.12.0, it should be 2.20.0 -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Interesting patch. From where did you get that impressive list with device id numbers?

Current kernel sources: drivers/gpu/drm/gma500/psb_drv.c

Is the resulting rpm available somewhere, would it make sense that I install that one and test it?

After this I looked for the updated xf86-video-intel, but that is no longer present (did you remove it from the repository?).

No, it's still there and an update to 2.20.1 is planned. Thanks for confirmation, that the patch fixes the issue. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

This makes not much sense. intel is definitely the wrong X driver for this GPU.
