I believe I am seeing this issue as well within a day after a fresh install of 10.10. I hadn't done too much from the default install, so I thought listing what I had done might be helpful in narrowing down the possibilities.
I do not yet have a sequence of events to trigger the issue, but I have only had the system up for 2 days and X has died at least 10 times. My system: Abit AN-M2HD AMD x2 4600+ evga nvidia geforce 210 1) installed from the amd64 alternate 10.10 cd (via usb) 2) updated packages 3) Switched to using nvidia-current 4) Turned off compiz and turned compositing on for metacity (for compatibility with docky) 5) installed vlc, x11vnc, mplayer, smplayer, deluge, deluged, deluge-webui, python-setuptools, flexget, ubuntu-restricted-extras, docky, gnome-do, vdpau-va-driver, filezilla, nautilus-open-terminal, pavucontrol, openssh-server, emacs, cron, vsftp 6) Setup 'echo "options snd-hda-intel enable_msi=0 probe_mask=0x102" | sudo tee /etc/modprobe.d/nvidia-hdmi.con' (required to make pulseaudio use the right alsa sound device to get audio over hdmi working) 7)) Setup x11vnc to load as root at bootup by adding "/usr/bin/x11vnc -auth guess -o /var/log/x11vnc.log -forever -bg -rfbauth /home/belgarth/.vnc/passwd" into /etc/gdm/Init/Default 8) Setup Deluged and deluge-webui to load at bootup using the instructions at http://dev.deluge-torrent.org/wiki/UserGuide/InitScript/Ubuntu (including creating a new deluge user) 9) setup flexget to run every 5 seconds via crontab I suspect the issue involves one or more of the following: flexget running (python script), the nvidia proprietary drivers, x11vnc running at bootup as root. I have tried adding in X-swat updates ppa in an attempt to try to fix the issue with no luck. So far, the simplest sequence of events leading to the crash was after a fresh boot, I connected via vnc and logged into the device via vnc and let it sit there. Within an hour X reset. But I have done the same since with no X restart. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/696995 Title: Sudden Crash out to Login Screen -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
