This section discusses helpful tips for getting GDM working. In general,
if you have a problem using GDM, you can submit a bug or send an email
to the gdm-list mailing list. Information about how to do this is in
the Introduction section of the document.
If GDM is failing to work properly, it is always a good idea to include
debug information. To enable debugging, set the debug/Enable key to
"true" in the <etc>/gdm/custom.conf
file and restart GDM. Then use GDM to the point where it fails, and
debug output will be sent to the system log file
(<var>/log/messages or
<var>/adm/messages depending on your Operating
System). If you share this output with the GDM community via a bug
report or email, please only include the GDM related debug information
and not the entire file since it can be large. If you do not see any
GDM syslog output, you may need to configure syslog (refer to the
syslog man page).
There are a many problems that can cause GDM to fail to start, but
this section will discuss a few common problems and how to approach
tracking down a problem with GDM starting. Some problems will
cause GDM to respond with an error message or dialog when it tries
to start, but it can be difficult to track down problems when GDM
fails silently.
First make sure that the Xserver is configured properly. The
GDM configuration file contains a command in the [server-Standard]
section that is used for starting the Xserver. Verify that this
command works on your system. Running this command from the
console should start the Xserver. If it fails, then the problem
is likely with your Xserver configuration. Refer to your Xserver
error log for an idea of what the problem may be. The problem may
also be that your Xserver requires different command-line options.
If so, then modify the Xserver command in the GDM configuration file
so that it is correct for your system.
Also make sure that the /tmp directory has
reasonable ownership and permissions, and that the machine's file
system is not full. These problems will cause GDM to fail to start.
