Today, after simply restarting my computer Kwin now crashes upon trying to re adjust my dual screen set up. When logging back into KDE my panels where black, instead of being transparent. Here’s the error kwin gives me: Executable: kwin PID: 2472 Signal: Segmentation fault (11) http://i.imgur.com/guf75lt.png
Upon further looking i found that the composting defaults to Xrender when i had it on OpenGL. Every time i close the desktop effects windows it goes back to Xrender. I i have strange suspicion that this has something to do with Compiz.
Do you mind giving the primary information: which version of openSUSE?
openSUSE 12.3 with tumbleweed repos.

i don’t remember, but didn’t someone already tell you to forget
compiz…it is SO old technology…afair everything that compiz
could ever do (in the old days) KDE can do it all, and more…and,
compiz just gets in the way.
To the op, You didn’t mentioned what’s the kind of setup you did on your dual screen.
If you are trying to enable xinerama it’s not gonna work. If you are using twin view and
separate X screen, kwin should work.
removed compiz. Still have the same problem.

was an update done before the reboot? (not just before but anytime
before? like, maybe you did power off reboot two weeks ago and have
been doing a hibernate since?)
if so there could easily have been something (the kernel maybe)
running out of memory and then changed out with the first reboot
after install…and, BANG if you are using a nVidia driver, or any
other critical proprietary driver you are dead in the water until you

you are in the wrong forum…post only to tumbleweed forum…
I sometimes see this.
I have seen it most often on an older computer using the radeon graphic driver. I have seen it less often with an nvidia graphics card and the nvidia driver. It has never happened on my system that uses Intel graphics.
It mostly happens when I first login after setting up a new user, or first login after deleting “$HOME/.kde4”. Once I turn off desktop effects, that usually stops it.
Maybe something is wrong with your gfx driver?
Please show the output of:
glxinfo | grep render
(you may have to install the package “Mesa-demo-x”) first.
