After conection I get this error report. This error is new with the Ubuntu 12.04 beta installation. After the error message, the connection seems to be working. (I am running the crash reporting assitant through the same connection.) The only additional problem was that automatic debug library installation did fail, it apparently did ot succed in creating the required authorization window. I am using KDE, because I have problems with Gnome in this configuration. The Gnome problem is caused by the window manager detecting my Nvidia graphics card, and assuming that the highend features are also available on the NX connection, when they are not available. The crash can be reproduced every time. -- Backtrace: Application: KWin (kwin), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
