Switching off XGL

Hi, I installed XGL and Compiz on my Opensuse 10.1 KDE 3.5.4 desktop to 'have a play'. Following the instructions on here: http://en.opensuse.org/Using_Xgl_on_SUSE_Linux#Using_Compiz_with_the_KDE_des... Very impressed with it, however as I'm only running a 1.8GHz CPU it's a bit too demanding even with all the effects switched off. Also as it replaces my window manager all the KDE settings are redundant. However if I switch of XGL the Window boarders are missing and my keyboard doesn't work. What should I/How can I set my KDEWM to to revert things back to normal? Regards Matthew
