Version: (using KDE 4.3.4) OS: Linux Installed from: Debian testing/unstable Packages I use my Notebook connected to a port replicater and an external Screen with higher resolution. Very often KDE crashes when - I try to switch between X-consoles (different users) - I release the notebook from the port replicator This problem has high severity because in this case when rebooting Linux my system partition will always be checked what in reality means: The crash produces file system errors!

classical x server - probably driver - problem. if you are using closed-source nvidia or ati drivers, report to them. otherwise, report to xorg. btw, in this case it is "safety", not "security".
