** Description changed: System: Ubuntu Intrepid Ibex (beta) 8.10 up to date as of 11 Oct 2008. linuxr...@fdetienn-desktop:~# uname -a fdetienn-desktop 2.6.27-7-generic #1 SMP Fri Oct 10 03:55:24 UTC 2008 i686 GNU/Linux r...@fdetienn-desktop:~# lsb_release -rd Description: Ubuntu intrepid (development branch) Release: 8.10 This is going to be a messy report as I see things but do not know in which order they happen or even if they are truly related. They are correlated though. I am running Ubuntu 8.10 on a Dell Hybrid Studio. 4GB RAM and X3100 Intel accelerators. When leaving X running for some time (undetermined yet) with an OpenGL screensaver (Hypertorus in this case), the system display finally hangs and I can not return to session (not even a password prompt). The screen remains black and backlit. SSH still works and I see Hypertorus spinning at 100% CPU. If I kill Hypertorus and gnome-screensaver, the screen flashes once but nothing better happens. I then see Xorg at 100% CPU. If I kill X, gdm restarts it and I get a user prompt. After typing my username/password, X wipes the screen and I see an orange background but then X goes back spinning at 100% CPU. This takes me to the previous point. There is never a way to get a working X display. The VT consoles are also broken; they remain with corrupted leftovers of the X display (I see part of the orange background and the mouse pointer + some colorful areas). The only outstanding message is: [42627.033483] mtrr: type mismatch for d0000000,10000000 old: write-back new: write-combining [42772.634036] mtrr: type mismatch for d0000000,10000000 old: write-back new: write-combining [42810.157626] mtrr: type mismatch for d0000000,10000000 old: write-back new: write-combining from kernel.log (also visible in dmesg). I will see if the problem happens without OpenGL screensavers. + + [lspci] + 00:00.0 Host bridge [0600]: Intel Corporation Mobile PM965/GM965/GL960 Memory Controller Hub [8086:2a00] (rev 03) + Subsystem: Dell Device [1028:0279] + 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller [8086:2a02] (rev 03) + Subsystem: Dell Device [1028:0279]
