I've discovered this bug bites if a custom xorg.conf is used to set the monitor data-rates for displays that don't provide EDID/DDC data (see bug #288807 "[i815] Wrong resolution on Vaio PCG-SRX51, PCG-SRX41 and PCG-FX370 due to incorrect h/v rates ").
In this case the xorg.conf that works successfully for Karmic 9.10 with Xubuntu causes this bug with Lucid 10.04 Xubuntu. Without the custom xorg.conf the xserver will start but only with a lower resolution and using only a small part of the LCD area. I've attached a tar.gz archive that contains the custom xorg.conf, the user .xsession-errors, and all the logs from /var/log/ captured after a clean boot. The /var/log/Xorg* and /var/log/gdm/* logs were deleted prior to restart so the logs contained in the archive relate to the current start only. ----- xorg.conf ----- Section "Device" Identifier "Intel Corporation 82815 CGC" Driver "intel" EndSection Section "Monitor" Identifier "LCD Panel 1024x768" Option "DPMS" HorizSync 28-64 VertRefresh 43-60 EndSection Section "Screen" Identifier "Default Screen" Device "Intel Corporation 82815 CGC" Monitor "LCD Panel 1024x768" DefaultDepth 16 SubSection "Display" Modes "1024x768" EndSubSection EndSection Section "ServerLayout" Identifier "Default Layout" Screen "Default Screen" EndSection ** Attachment added: "Archive contains all logs, xorg.conf, and .xsession-errors" http://launchpadlibrarian.net/40260022/lucid-2010-03-04-logs.tar.gz -- [Lucid] Segfault in libint10 when restarting xserver or using custom xorg.conf https://bugs.launchpad.net/bugs/532579 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
