Hi openSUSE community, I have a strange problem with X under openSUSE 11.2. After starting KDE 4.x or Gnome, the Xorg system freezes after 5-15 minutes. If that occurs I can still move the mouse, but any click or keyboard event is not recognized any more. Can't switch to console. But the system itself works, since I can login by ssh. All running (server) applications like Apache and MySQL still work. In order to use X again, I have to reboot (init 6 does not work, I have to type "reboot " twice). init 3 and init 5 does not work after logging in by ssh, killing X process does also not fix it. I really have to reboot. I have an Intel 855GM Integrated Graphics Device on board. I have already checked the RAM with memtest, everything okay. There are no error messages in syslog. I have tried disabling DRI, but no effect. Disabling Video cache in BIOS or reducing the video buffer size did also not help. Without logging in to KDE or Gnome the system runs stable for weeks, so I am pretty sure that Xorg is the problem. I guess that these problems are caused by the Intel graphics driver. I can remember that I had similar problems 1-2 years ago (freezes only with KDE 3 and 4, not Gnome). I am pretty sure, that the first problems started after switching to the Intel driver (from the old 810 driver), but in openSUSE 11.1 it was running fine. Now in openSUSE 11.2 the X system freezes after some minutes working. == System Info == lspci -v: 00:02.1 Display controller: Intel Corporation 82852/855GM Integrated Graphics Device (rev 02) Subsystem: Intel Corporation 82852/855GM Integrated Graphics Device Flags: fast devsel Memory at 80000000 (32-bit, prefetchable) [disabled] [size=128M] Memory at 7e100000 (32-bit, non-prefetchable) [disabled] [size=512K] Capabilities: [d0] Power Management version 1 ---- xorg.conf: Section "Module" Load "dri" Load "dbe" Load "extmod" Load "glx" EndSection Section "ServerFlags" Option "AIGLX" "on" Option "AllowMouseOpenFail" "on" Option "ZapWarning" "on" EndSection Section "Device" BoardName "855 GM" Driver "intel" Identifier "Device[0]" Option "EXANoComposite" Option "monitor-VGA" "Monitor[0]" VendorName "Intel" EndSection ---- cat /proc/mtrr: reg00: base=0x000000000 ( 0MB), size= 2048MB, count=1: write-back reg01: base=0x07e000000 ( 2016MB), size= 32MB, count=1: uncachable reg02: base=0x07ff00000 ( 2047MB), size= 1MB, count=1: write-back ---- See also Xorg log attached. Any ideas ? Thanks in advance Ralf
