I just realized that on my system, KDE is running in "failsafe mode", which means no effects, themes, etc. I cannot figure out why, or what to do about it.
Systemsettings > desktop effects
has a checkbox for enabling effects at startup (which isn't working), but no way of turning them on or off. The shortcut (Alt-Shift-F12) does nothing.
There are no errors in /var/log/Xorg.0.log
The "toggle compositing" plasmoid does nothing.
Edit: I just noticed that hitting alt-shift-f12 does produce a momentary flash of desktop effects, but it lasts only a fraction of a second. Still no errors in Xorg.0.log, so maybe not a video driver problem.
