Description of problem:
This is a new deployment of RH WS 3.0 for my organization. We are
replacing our existing RH 7.3 installations.
When a user logs out of Gnome Desktop or a machine is rebooted after
the person has been logged in, we get the error popping up that says:
There already appears to be an X server running on display :0
Should I try another display number? If you select <No> X tries to
restart itself and fails.
I have been unable after this to get X running again on the system. I
have had to reinstall from my master image to get the workstation
I have this happening on two systems. One is a Dell Dimension 4400 and
one is an Optiplex GX240.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Have the user log out of Gnome
2. Restart the system, or sometimes the logout will fail.
3. The X server startup will fail.
Expected Results: The X display manager should come up and allow the
user to login to the system under runlevel 5.
I believe this is a gdm bug rather than an XFree86 bug. If there
is an X server already running, it stands to reason that it's only
because gdm hasn't removed the previous X server invocation.
In other words, the X server just runs until it is killed by something
else. If it is running and gdm tries to start another one on the
same display, then I would consider that to be a gdm bug, as it
1) Kill the previous X server first.
2) Start the X server on a new display.
Reassigning to gdm component for further investigation/comment.
I just tried to reproduce this with gdm on RHEL 3, and wasn't able
to reproduce. Is there something specific about your configuration
perhaps that might be causing this?
What video hardware are you using, and what video driver?
That might help provide additional clues as to what may be happening.
Thanks in advance!
