I found that the cause of this problem is that, when using the custom xorg.conf (and presumably failsafes?), the vesa module isn't loaded. Simply adding a Modules section to the custom xorg.conf solved the issue:
Section "Module" Load "vesa" EndSection This combined with the custom monitor settings finally allows Lucid to display 1024x768 across the full LCD, which allows the woraround for bug #288807 to function again. -- [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
