RE: X taking lots of CPU

["Cannon, Andrew" <Andrew Cannon nnc co uk>]

Stephen,

Going to runlevel 3 is fine for me, but what about the other users on the
network? Can they still log in to the system when it is in single user mode
(am I right in thinking that runl level 3 is single user mode)?

If you're using the KDM/GDM/XDM you will definitely suck more CPU time
down - but if you change to runlevel 3 and login via console and start
Xwindows with the "startx" command, you'll find that XWindows doesn't
eat up all that CPU...

Found that out the hard way...no wonder I never liked graphical
logins...
