switch user or switch to console failes on first try in intrepid

[ercferret18]

Binary package hint: gdm

When I try to switch user or switch to a console (Ctrl+Alt+F1), it fails to switch on the first try, saying something like (Xorg failed to switch)

but it does work the second time

[Sebastien Bacher (seb128)]

the issue is rather an xorg one

Hi ercferret18,

Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

(by the way, it doesn't happen every time I try it, just once in a way)

output of lspci -vvnn:

I don't think I edited my Xorg file

This bug also happens to me. I am attaching my Xorg.0.log here. The log includes log entries after four Ctrl+Alt+F<n> strokes (n = 1..6). Stroke #1 is the first attempt to switch to a VC (virtual console). It failed in the following way: the corresponding virtual console (VC) appeared for a split second, but then the X screen reappeared. If this happens, retrying it (stroke #2) immediately always succeeded.
Stroke #3 also failed: it took place several minutes apart (I have no idea about the exact time interval) from the strokes #1 and #2. Stroke #4, a retry of stroke #3, also succeeded. In brief, after one failure, other following attempts would succeeded if they are closely spaced. But then if we don't switch to any VC for a period of time (maybe several minutes), then attempting to switch to one of the VCs would "fail" as I descibed above.

I am using Xubuntu 8.10 with the following package versions:

xorg version 1:7.4~5ubuntu3
linux kernel: linux-image-2.6.27-10-generic , version 2.6.27-10.20

The hardware is Dell Lattitude D600 with the following peripheral:

The X driver used is the open-source ATI driver in the xorg package.

The following bug has Ctrl+Alt+F<n> as a workaround, but the secondary bug with the virtual console described here adds even more inconvenience to the use of LInux on Dell laptops:
