Hi there, Sorry for the cross-listing but I have been struggling for 
days now trying to fix this. It started in a RH9 system after running 
up2date last week to upgrade the kernel. Once I rebooted (runlevel 5) 
the GUI login window stop showing up and instead I get a blue window 
informing me that: "There already appears to be an X server running on 
display :0.  Should I try another display number? ". I eventually get 
thrown to a terminal where I can login and run "startx" with no 
problem. I get the same behavior if try to start gdm manually.
I took the opportunity to upgrade to fedora core1 hoping to fix my 
problem but after running yum yesterday to upgrade the whole system I 
still get the same problem. I have turned "Debug" on in gdm.conf and 
this is the part of the logs in /varr/log/messages concerning gdm:

  I have checked XFree86 logs and everything seems fine. The logs for 
gdm at /var/log/gdm show that the X server is been loaded twice (that I 
think is also shown in the output above) for some reason:
*****start quote*****
  /var/log/gdm/:0.log shows
  Fatal server error:
  Server is already active for display 1
  If this server is no longer running, remove /tmp/.X1-lock
  and start again.
*****end quote******

while  /var/log/gdm/:0.log.1 looks normal (loading /etc/X11/XF86Config) 
and is the one responsible for that .X1-lock file.

I have no idea what might be causing this, specially the extra X server 
calls. Any ideas? Thanks...

 This is what ps -axf shows:

*****start quote*****

9294 ?        S      0:00 gdm-binary

9300 ?        S      0:00  \_ gdm-binary

9305 ?        S      0:00      \_ /usr/libexec/gdmopen -l /bin/sh -c
/usr/bin/dialog --yesno 'There already appears to be an X server
running on display :0.  Should I try another display number?  If you
answer no, I will attempt to start the server on :0 again.

 I have checked XFree86 logs and everything seems fine. The logs for
gdm at /var/log/gdm show that the X server is been loaded twice (that
I think is also shown in the output above) for some reason:

*****start quote*****

 /var/log/gdm/:0.log shows

 Fatal server error:

 Server is already active for display 1

 If this server is no longer running, remove /tmp/.X1-lock

 and start again.

*****end quote******


while  /var/log/gdm/:0.log.1 looks normal (loading
/etc/X11/XF86Config) and is the one responsible for that .X1-lock file.


I have no idea what might be causing this, specially the extra X
server calls. Any ideas? Thanks...
