How reproducible:

Steps to Reproduce:

4. logout from X                  -> X restarts on vt9, 11 (seems to vary)

Comment 1 Joachim Frieben 2007-05-16 08:58:25 EDT
The same for an IBM ThinkPad T23. Using the VESA framebuffer does not bring
any improvement either. In general, after switching more than once to a VT1
and back, then switching to VT1 leaves one with a monitor going to standby
mode. At this point, it also impossible to switch back to VT7.
At least, ctrl-alt-del allows to reboot the machine gracefully. However,
I do not see a regression. Savage VT switching has always been like that for

Thanks for the bug report.  We have reviewed the information you have provided
above, and there is some additional information we require that will be helpful
in our diagnosis of this issue.

Please attach your X server config file (/etc/X11/xorg.conf) and X server log
file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file
attachments using the bugzilla file attachment link below.

Could you please also try to run without any /etc/X11/xorg.conf whatsoever and
let X11 autodetect your display and video card? Attach to this bug
/var/log/Xorg.0.log from this attempt as well, please.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

X server logfile without xorg.conf (fails to start!)

X server fails to start without xorg.conf on my system, because it selects
framebuffer device instead of the savage device.

All 3 files are now attached as requested.

X server logfile with xorg.conf and VT switch

Sorry, late at night, forgot to also attach a X server log with an VT switch
that shows the problem. I don't see any error/problem messages there though...
Comment 8 Stefan Becker 2007-11-10 17:10:24 EST
Just updated to F8: problem is gone.

Comment 9 Stefan Becker 2007-11-25 02:15:06 EST
FYI: Was probably fixed by this commit included in 2.1.3 release:
