14.4.3. Problems with the X Window System (GUI)
If you are having trouble getting X (the X Window System) to start, you may not have installed it during
your installation.
If you want X, you can either install the packages from the Red Hat Enterprise Linux CD-ROMs or
perform an upgrade.
If you elect to upgrade, select the X Window System packages, and choose GNOME, KDE, or both,
during the upgrade package selection process.
14.4.4. Problems with the X Server Crashing and Non-Root Users
If you are having trouble with the X server crashing when anyone other than root logs in, you may
have a full file system (or, a lack of available hard drive space).
To verify that this is the problem you are experiencing, run the following command:
df ­­h
The
df
command should help you diagnose which partition is full. For additional information about
df
and an explanation of the options available (such as the
-h
option used in this example), refer to the
df
man page by typing
man df
at a shell prompt.
A key indicator is 100% full or a percentage above 90% or 95% on a partition. The
/home/
and
/tmp/
partitions can sometimes fill up quickly with user files. You can make some room on that
partition by removing old files. After you free up some disk space, try running X as the user that was
unsuccessful before.
