This report cannot be handled without further information. Please run "gdb --args kwin --replace" from the command line, and when it crashes, use "bt" to obtain a backtrace. If the panel also crashes, it could be a lower level problem, such as with video drivers. Please check, which other components besides KDE you updated. you neither get a "kwin just crashed" dialog? smells like OOM - depending on how ubuntu is configured, there will be a notion in demesg; otherwise just watch out for memory usage. in any case, a better description and ideally a backtrace is inevitable. PS: if this happens "after i updated the system", that's pretty common with ubuntu. suspicion is that they truncate files on installation ("use cp instead of install") "you neither get a "kwin just crashed" dialog?" Normally no, but it seems to have given me one this time: Application: KWin (kwin), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
