I used init 0 to make server shutdown,and replaced the power cord
when I boot the server,it can’t enter the GUI
then I used init 5 and get the following message
Could not start the X
server (your graphical environment)
due to some internal error.
Please contact your system administrator
or check your syslog to diagnose.
In the meantime this display will be
disabled. Please restart GDM when
the problem is corrected.
Not intentionally, but your server may have had pending kernel updates including video driver that were applied when the server rebooted.
The ATI drivers give my system a headache. For some reason ATI’s “flgrx” never works on my system, and I have to change /etc/X11/xorg.conf to use the “radeon” driver.
