Public bug reported: This behavior is 100% reproducible. I have freenx-server installed from here: https://launchpad.net/~freenx-team/+archive/ppa
And am logging in from a remote machine with the newest nxclient from nomachine.org. What happens is that upon login or shortly thereafter, kwin crashes with a segfault. After restarting, it crashes at regular intervals as well. I reported a bug to the KDE4 tracker: https://bugs.kde.org/show_bug.cgi?id=298370 And it was marked a duplicate of a bug NOT related to NX: https://bugs.kde.org/show_bug.cgi?id=293209 Judging from the backtrace, and from the comments in bug 293209, the problem is related to Xorg, and the people at KDE seem to think that the problem might even be Ubuntu 12.04 specific. So I decided to re-report the bug here and give you pointers to the relevant KDE bugreports. We are really desperate to get Kwin working under NX and are willing to test whatever you like! Many thanks in advance.
