Version: (using KDE 4.1.2) OS: Linux Installed from: Ubuntu Packages I updated Kubuntu 8.04.1 to 8.10. Upon restart, number of desktops was one from 4 i use. Every time i set the number of desktops to 4, click to one of them and open a new application in that desktop, a crash occurs, and my desktops are reduced to 1 again. I dont use compiz and have disabled the kde desktop effects. Video card is nvidia 6150 with Nvidia drivers.

openSUSE 11.1 Beta(3Plus -5), KDE 4.1.2/4.1.72 reports that kwin crashed, backtrace shows nothing. On another box with 4.1.2, everything is normal. On this box, the screen suddenly changes to show all windows jumbled up, CTRL-F1 CTRL-F7 brings all back to normal. The bad box has an GEForce 8800GTS and the good one has a GEForce 9600, both running NVIDIA-Linux-x86_64-177.80 driver and I THINK it started happening after this driver was installed. For the first time I suffered a hard lock up while trying to file this report. Back up now on KDE 3.5.10 which works without problems. Just noticed the thread is for Ubuntu, can file a new bug if it is not pertinent to the present subject.
*** Bug 176001 has been marked as a duplicate of this bug. ***
After update to KDE 4.2 RC1 everything works ok now.
@gd: can you confirm this is working on KDE4.2+ ? Thanks
from comment #4 I assume this has been resolved. If not please reopen.
*** Bug 300672 has been marked as a duplicate of this bug. ***
there seems a bug in cascaded placement
the issue is that Placement::reinitCascading() is just called somewhen when reconfiguring and not whenever Workspace::setNumberOfDesktops() is called. This bug doe only affect cascaded window placement (kcmshell4 kwinoptions, last tab) -> switch to some other strategy to prevent it until the fixed version hits your distro. https://git.reviewboard.kde.org/r/105063/
yes, i'm using cascade window placement. thanks for looking into it! :)
