I attempted to enable desktop effects, but that made my screen go black, then white. I had to “CTRL-ALT-BACKSPACE” to shut down KDE and log in again as root, navigate to /home/les/.kde/share/config/kwinrc.
There I changed
and rebooted. That got me up and running again without compositing. (Who needs wobbly windows anyway?)
I suspect I haven’t got the non-free nvidia drivers installed. I’ll have to look into that, iffen I can ever get Synaptic to run. Synaptic just won’t start. It will get as far as asking for my root password, then nothing happens. Maybe I’ll try Kpackage, if there is one for KDE 4.
