Comment 4 for bug 526379

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?
