           Summary: Display corruption when switching to console with
                    X1400
           Product: xorg
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: vjr at iki.fi
         QAContact: xorg-team at lists.x.org


When switching to console with compositing enabled (with compiz), the display
comes up garbled (still displaying a part of the gnome desktop in my case).
Switching back to X still works, but the console is unusable. The same garbled
display comes up when X is killed upon system shutdown.

This only seems to happen when compositing is used, KMS is disabled and after
the user has logged out of the system at least once.

STEPS TO REPRODUCE:
1. Login with gdm
2. Switch to console (Ctrl-Alt-F1)
   Everything fine at this point
3. Log out
4. Login with gdm
5. Switch to console
6. The display is garbled

This does not seem to happen when KMS is enabled.

VERSIONS:
kernel 2.6.34.1
xf86-video-ati 6.13.0/6.13.1/latest git
compiz 0.8.6
xorg-server 1.8.1.902
gdm 2.30.4
