Plasma kwin can't move or resize windows [still broken]

[jesnow]

Every few weeks I run into the problem (always at the worst possible moment) that kwin stops allowing me to move or rezise windows. It's essentially identical to this bog post from 2005 (a very different version of KDE!):

But almost the same workaround:

Code: Select all

killall kwin_x11
kwin_x11 --replace &

The hplip service widget is stuck in the upper left hand corner of the screen after this, but otherwise everything seems to work.

Any insight on the issue would be welcome.

Just happened again. This time the restart of kwin_x11 was not successful. In fact kwin is now persistently broken (ie after logout, reboot) and will not start. Windows have no borders, etc. On startup, the screen flashes several times and then borderless windows appear that can't be moved or resized.

Very very broken.

I have limited functionality now (at least I have some!), but badly need help.

Code: Select all

My problem seems to be a bad interaction between kwin and the nvidia driver. the workaround for the moment indeed seems to be to use another window manager, so I switched to openbox for now.
