IMPORTANT
Do not edit the runlevel configuration manually. Otherwise SuSEconfig (run by
YaST) will overwrite these changes on its next run. If you need to make manual
changes here, disable future SuSEconfig changes by setting
CHECK_INITTAB
in
/etc/sysconfig/suseconfig
to
no
.
If the runlevel is set to
5
, you might have corruption problems with your desktop or X
Windows software. Examine the log files at
/var/log/Xorg.*.log
for detailed
messages from the X server as it attempted to start. If the desktop fails during start, it
might log error messages to
/var/log/messages
. If these error messages hint at
a configuration problem in the X server, try to fix these issues. If the graphical system
still does not come up, consider reinstalling the graphical desktop.
One quick test: the
startx
command should force the X Window System to start with
the configured defaults if the user is currently logged in on the console. If that does not
work, it should log errors to the console. For more information about the X Window
system configuration, refer to
Chapter 26, The X Window System (page 481).
51.4 Login Problems
Login problems are those where your machine does, in fact, boot to the expected wel-
come screen or login prompt, but refuses to accept the username and password or accepts
them but then does not behave properly (fails to start the graphic desktop, produces
errors, drops to a command line, etc.).
51.4.1 Valid Username and Password
Combinations Fail
This usually occurs when the system is configured to use network authentication or
directory services and, for some reason, is unable to retrieve results from its configured
servers. The
root
user, as the only local user, is the only user that can still log in to
these machines. The following are some common reasons why a machine might appear
functional but be unable to process logins correctly:
• The network is not working. For further directions on this, turn to Section 51.5,
“Network Problems” (page 926).
