I currently have Gnome as my default WM but would like to change it to KDE. At runlevel 5 I get a selection of WM in a list. When I picked KDE from the list, the login manager asked if I wanted to make KDE my default. I put yes but when I logged back in later, I didn't go into KDE. I went back to Gnome even after I have changed the default. The login manager I'm using is the default Gnome login screen. I'm sure you guys know what I'm talking about. If not, I could give you a screenshot.

So I thought I might go into the files to find .xinitrc because when I had it at runlevel 3 before I could go to .xinitrc and fix the problem there. This time around I went looking and didn't find a .xinitrc file. So I'm at a lost. I don't know where I can go to change the default WM. Does anyone know of another way to change the WM?

perhaps yast2->system->/etc/sysconfig Editor-> Desktop -> Window Manager -> DEFAULT_WM helps...

Nevermind, I believe I found the problem. After I have chosen which one to be my default WM, I didn't reboot. This in turn set my default WM back to Gnome because it was as though I had made no changes. So I tried making KDE my default again, then reboot immediately after. Surely enought once I logged in, KDE booted up. I hope that helps anyone that comes across a similar problem to mine.
