tags #28 pending fixed thanks Hi all, The issue is solved on the X2Go side, however please note that the crashing kwin process is a Ubuntu-only bug and probably due to one of their libXrandr patches applied on top of KDE4. The issue does not occur on Debian. From the X2Go side we could do as much as possible: Use libXrandr from libnx-x11: http://code.x2go.org/gitweb?p=x2goserver.git;a=commitdiff;h=1590476de31766028725fa1272dfcc50b7d1305e http://code.x2go.org/gitweb?p=nx-libs.git;a=commitdiff;h=b8605d4d6c6f02466ab7586c8ece6b4bd9570751 LD_LIBRARY_PATH bug: http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=29 -> http://code.x2go.org/gitweb?p=x2goserver.git;a=commitdiff;h=0b3c71ca7b6e3681a2ade80346621b22ffa7f255 So, what we have after these fixes: + Kubuntu startsup ok. + Kubuntu still crashes when a resize event occurs on the session window -> This is not relevant to X2Go thin clients, though, as they do not resize the desktop. + you cannot resize the display resolution in Kubuntu (using RandR, Resize and Rotate) IMHO, this has to be solved in the Ubuntu version of KDE.
