PC Hangs when going from runlevel 3 to 5
Suse 9.0 - KDE 3.1
PC boots to runlevel 5 - I can log into the GUI sucessfully, and can drop to runlevel 3 (to save resources for running Daemons/ftp/etc) by entering init 3 at the command line.
However, when I try to go back to runlevel 5 (by entering init 5 at the command prompt) the computer loads the GUI login box and allows me to complete the GUI login again, but hangs immediatly thereafter at a blank blue (graphical) screen.... what you would see just before the KDE loading window appears. restarting the X server (cntrl+alt+backspace) takes me back to a frozen command prompt.
Am I going about changing runlevels the wrong way? If not, what logs should I check / where should I begin the troubleshooting process?
Any help would be greatly appreciated!
