Plasma crash solved by downgrading NVIDIA drivers

It’s been mentioned several times in this forum already that downgrading to NVIDIA driver version 256.53 can solve random-seeming plasma crashes (the error dialog box usually mentions a “floating point error”).

So, I upgraded openSUSE 11.3 to KDE 4.5.5 today and couldn’t add a clock - any clock - to my desktop or panel without a plasma crash. I had been using the latest NVIDIA kernel modules (v260.19) from the openSUSE NVIDIA repo. I uninstalled them, installed the gcc, make, and kernel-devel packages, and manually installed the latest NVIDIA driver (270.18). No joy; same crash. So I installed version 256.53. And…it solved the problem.

So, to underscore the point, if you have a recent NVIDIA card and you’re having random plasma widget crashes, try downgrading your NVIDIA driver.

Thanks for the tip, guys.

i wonder out loud: should one having such problems also make sure
there is a bug reported on the driver which does not work?
