I have the same problem and even used with lxdm kde doesn't start just loops back to lxdm Additional information based on some feedback in the factory-ml. The above results were on a system running Factory, but with the 3.3-rc5 kernel from Kernel:HEAD. My system is running 64bit. For reference, I filed bug 749608 a few days ago; different trace, but likely the same issue in the end. But stills remains 3.3-rc6. Doing some further research on this bug and it seems that I have found the root cause. When building the driver with the standard buildflags, then the Xorg server behaves normally and everything works as expected. Checking the change log of the xorg-x11-driver-video package indicates the following: Sat Feb 25 13:56:15 UTC 2012 - sndirsch@suse.com - build intel driver with SandyBridge's New Acceleration (SNA) Disabling the SandyBridge's New Acceleration delivers for me a working Xserver. Checking the internet on this new Acceleration, then it seems there are quite some problems with it and that it is not that mature yet. As I am not sure if the latest intel graphics cards needs this specific acceleration or not, I would suggest to either create a new package for an intel driver without SNA or to disable the SNA in the main driver package for now. *** Bug 749608 has been marked as a duplicate of this bug. *** Back to UXA. *** Bug 752377 has been marked as a duplicate of this bug. *** is there a way to let the X server create a coredump instead of this almost always totally useless backtrace? I created a bug upstream, independent on this report. https://bugs.freedesktop.org/show_bug.cgi?id=47597 Will try to add a better backtrace there. reopening .. i'll try to supply a coredump. i915 + Xorg is pretty unstable on sandy bridge gen2.. However Xorg doesn't crash it rather freezes over and over at certain conditions .. # lspci 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 00:16.0 Communication controller: Intel Corporation 6 Series Chipset Family MEI Controller #1 (rev 04) 00:16.3 Serial controller: Intel Corporation 6 Series Chipset Family KT Controller (rev 04) 00:19.0 Ethernet controller: Intel Corporation 82579LM Gigabit Network Connection (rev 04) 00:1a.0 USB Controller: Intel Corporation 6 Series Chipset Family USB Enhanced Host Controller #2 (rev 04) 00:1b.0 Audio device: Intel Corporation 6 Series Chipset Family High Definition Audio Controller (rev 04) 00:1c.0 PCI bridge: Intel Corporation 6 Series Chipset Family PCI Express Root Port 1 (rev b4) 00:1c.1 PCI bridge: Intel Corporation 6 Series Chipset Family PCI Express Root Port 2 (rev b4) 00:1c.3 PCI bridge: Intel Corporation 6 Series Chipset Family PCI Express Root Port 4 (rev b4) 00:1c.4 PCI bridge: Intel Corporation 6 Series Chipset Family PCI Express Root Port 5 (rev b4) 00:1d.0 USB Controller: Intel Corporation 6 Series Chipset Family USB Enhanced Host Controller #1 (rev 04) 00:1f.0 ISA bridge: Intel Corporation 6 Series Chipset Family LPC Controller (rev 04) 00:1f.2 SATA controller: Intel Corporation 6 Series Chipset Family 6 port SATA AHCI Controller (rev 04) 00:1f.3 SMBus: Intel Corporation 6 Series Chipset Family SMBus Controller (rev 04) 03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6205 (rev 34) 0d:00.0 System peripheral: Ricoh Co Ltd Device e823 (rev 08) 0d:00.3 FireWire (IEEE 1394): Ricoh Co Ltd FireWire Host Controller (rev 04) typical situation when it freezes is when playing some video on fullscreen. regards, daniel (In reply to comment #9) > is there a way to let the X server create a coredump instead of this almost > always totally useless backtrace? With KDM, there is DISPLAYMANAGER_KDM_LOCALARGS in /etc/sysconfig/displaymanager. Setting it to whatever X flags passes them to X. I.e. add there -core.

Right, we're back to UXA anyway. Created attachment 518512 [details]

Sorry, seems like a wrong bugreport. Will create new one. |
