I tried your method, Sebastien: I removed 1280x1024 and 1024x768 from xorg.conf and tried tdfx once again.
The first login (automatic login) failed and I got to GDM again, but the second login (manual one) worked, I got my session, but the desktop background was corrupted, and when switching to the text mode terminals, screens were also corrupted. So I'm back to "vesa". -- GDM Restarts after Desktop loads while using tdfx driver https://launchpad.net/bugs/68291 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
