I gave the same problem on Gutsy. Gdm ignores whatever I use into xorg.conf and keep a resolution that my screen does not support. After logging (blindly), everything is fine for the user that has setup his resolution manually in the preferences.
xorg.conf attached. Nothing into gdm logs... ** Attachment added: "xorg.conf" http://launchpadlibrarian.net/12047885/xorg.conf -- gsm/startx will ignore xorg.conf resolution settings and run with very low resolution https://bugs.launchpad.net/bugs/152109 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
