Maybe previous comment was presumptuous. I have the similar symptoms: have upgraded to lucid, can login to gnome failsafe, but not gnome normal session.
When watching the X output and the gnome-session output, I see X crash with output similar to that mentioned in bug #515846: "X: ../common/drirenderbuffer.c:69: driNewRenderbuffer: Assertion `format == 0x1908 || format == 0x8050 || format == 0x8058 || format == 0x81A5 || format == 0x81A6 || format == 0x81A7 || format == 0x8D48' failed. Aborted (core dumped)" After that because X has crashed, gdm restarts it and I end up back at the login screen. It maybe that we are experiencing the same symptoms but for completely different reasons? -- GDM login fails with regular gnome-session (lucid, i386) https://bugs.launchpad.net/bugs/526379 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
