Hi,

On Debian unstable, with X server running as !root, the following actions lead to the lockup/crash of the server:

  1. login with gdm, the server is spawned on vt2
  2. switch to vt1
  3. login as an other user
  4. logout (ctrl-D)

At this time, the vt is automatically switched to vt2 and the server stops responding and/or crash

As you can see in the logs, the radeon driver complains that it cannot access the device, so I'm not sure it's a general X issue or a problem with the driver.

The weird part is that I can switch from vt back to the X session without trouble as long as I don't exit the cli one
