Ok. I figure the problem out. I got an xorg.conf file from another user with a T61p, who didn't have any problems using kdm, and if I use his refresh settings, both gdm and kdm works again.
I changed the refresh settings from: Horizsync 30-70 Vertrefresh 50-160 to: Horizsync 28-96 Vertrefresh 43-60 Which solved the problem. -- gdm greeter crashes when X is using vesa driver https://bugs.launchpad.net/bugs/138718 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
