224 Start-Up 7 Once in the YaST System Repair module, select Expert Tools then select Install New Boot Loader. 8 Restore the original settings and reinstall the boot loader. 9 Leave YaST System Repair and reboot the system. Other reasons for the machine not booting may be BIOS-related: BIOS Settings Check your BIOS for references to your hard drive. GRUB might simply not be started if the hard drive itself cannot be found with the current BIOS settings. BIOS Boot Order Check whether your system's boot order includes the hard disk. If the hard disk option was not enabled, your system might install properly, but fail to boot when access to the hard disk is required. 9.3.2 Machine Loads GRUB Properly, but Does Not Boot into a Graphical Login If the machine comes up, but does not boot into the graphical login manager, anticipate problems either with the choice of the default runlevel or the configuration of the X Window System. To check the runlevel configuration, log in as the root user and check whether the machine is configured to boot into runlevel 5 (graphical desktop). A quick way to check this is to examine the contents of /etc/inittab, as follows: nld-machine:~ # grep "id:" /etc/inittab id:5:initdefault: nld-machine:~ # The returned line indicates that the machine's default runlevel (initdefault) is set to 5 and that it should boot to the graphical desktop. If the runlevel is set to any other number, use the YaST Runlevel Editor module to set it to 5. 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. For more information about X server configuration, refer to Chapter The X Window System (↑Reference). 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 The X Window System (↑Reference). 9.4 Login Problems Login problems are those where your machine does, in fact, boot to the expected welcome 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.). 9.4.1 User Cannot Log In—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 9.5, “Network Problems” (page 232). Common Problems and Their Solutions 225
