Some time ago, I tried using the program "kvdr" (thinking it was for sound, not video recording). Like a few others in my experience, it completely froze my system, leaving it unusable and forcing me to reboot. When I did this, I received the kdm screen, and chose "FVWM" just for the fun of it, to play around. Must have been a big mistake, because my system now

1) defaults to FVWM, with no kdm screen
2) freezes when I try to get to kdm from runlevel 3

Hence leaving KDE or other window managers inaccessible, except by running them on top of FVWM, which is very annoying.

Could somebody please help me with this? I'm using SUSE OSS 10, with the "propietary" ATI Radeon drivers if that makes a difference.

first, you can try xinit /usr/bin/<whatever you want, there is way to start KDE>
second, you can read files like ~/.xinitrc and ~/.kde/kdm (I don't remember KDE layout, so sorry)
Or try 'grep -i fvwm -r $(ls -A)' in ~

Post output - I'll try to say which file to edit (or guess yourself)

third, fvwm is better than KDE, but WindowMaker is even better (surely, this is just my opinion, and matter of taste).

Start Yast from the console.

Goto System then sysconfig editor

In sysconfig find Destop/Display manager/DISPLAYMANAGER Make the setting kdm

Then goto Desktop/Window Manager/DEFAULT_WM make sure it is set to kde.

do an init 6

See if that doesn't fix your problem.

Actually, I just changed the default display manager to xdm, rebooted, and got back into KDE. Thanks though.
