I'm seeing this on Oneiric (64-bit) with Xubuntu. I have a very repeatable test case:
1. Reboot.
2. Wait for autologin to occur.
3. Press enter on desktop.
4. X will crash, and I get dumped back to password prompt to login.
5. Then it works ok till I reboot again.
I tried the recommended suggestion of removing plymouth, but it isn't possible to do that in oneiric without removing the entire base-system.
Incidentally, I'm using a Lenovo S205 laptop, which has a radeon GPU but where I have NOT installed the binary driver, and the bootloader is grub-legacy (grub-2 won't work with EFI).
