crashes in the NVIDIA blob

Comment 2 Christoph Feck 2011-01-26 21:20:37 UTC

Well, it crashes because of memory corruption, which could have happened anyway. If you can reproduce it, we need a valgrind log.

Comment 3 Terrible Monster 2011-01-26 23:19:41 UTC

If I know how to give you a valgrind log, I shall do that. :)(In reply to comment #2)

before reading yourself into the mystics of valgrind:
- is it reproducable (does it happen whenever or at least often you do what you did)
   - if so, does it go away if you turn of the blur effect?

I keep my machine running for several days. I have 8 GB RAM and sometimes run many applications, including virtual machines. The more apps in memory, the less stable Kubuntu becomes.

The crash like this happened for the first time. More often the animation of virtual desktop wall loses frames with many apps running.
