Re: [gdm-list] Gdm hanging on startup.


Looking at the messages in the GDM debug log, it doesn't
seem that GDM is reporting any errors.  What causes
the computer to "turn void".  Is this power management?
There might be something wrong with the power management
that is causing your machine to lose keyboard and mouse
support.

Does the problem only happen with GDM, or if you leave
your logged in session idle for 2-3 hours does your
session also go into the same bad state?  Do other
display-managers such as KDM or XDM have the same
problem that GDM does?

I am running Debian Etch with an almost default
install on a laptop Thinkpad T22 (PentiumIII, 256MB of
RAM).
When starting X on bootup (via gdm 2.16.4) for the
first time after the machine has been power off for
quite a long time (2-3 hours), the screen turns void
and neither keyboard nor mouse are responding. Then I
have to power it off the barbarian way and start it
again and this time all works fine.
I had a look in the log files :
Nothing to mention in /var/log/Xorg.0.log : the server
starts exactly the same way wether or not the computer
hangs.
Nothing to mention in /var/log/gdm/:0.log, either.
When turning debugging informations on, we can learn
from /var/log/daemon.log that gdm "stops" after
attempting to open the display : here is an extract
from the file :

Is it gdm related ? Or could the problem be
kernel-related ?
I have had the same problem with all distros I have
used that have come after Ubuntu 6.06, included, that
is : Ubuntu 6.06 and following, Knoppix (I can't
recall the version number but that's one of the first
one that was shipped on a DVD) and Etch. On the other
hand, I have tried OpenBSD 4.1 and 4.2 and had no
problem.
Moreover I have quite a time ago tried to recompile
the Linux kernel (both the stock version and the
2.6.21 which was the newest at that time), deleting
some modules and other things and then it worked.
Now I am just trying to understand why...
Hyjial.
