Hi Miguel, Thanks for the backtraces. I must first say that I am absolutely not familiar with KDE, the QT environment and how it works. But the thread that raises the abort doesn't look like it's in the GL libraries code: Thread 1 (Thread 0x7fb33d8ec940 (LWP 2396)): [KCrash Handler] #6 0x00007fb337fca107 in raise () from /lib/x86_64-linux-gnu/libc.so.6 #7 0x00007fb337fcb4e8 in abort () from /lib/x86_64-linux-gnu/libc.so.6 #8 0x00007fb338748c28 in QMessageLogger::fatal(char const*, ...) const () from /usr/lib/x86_64-linux-gnu/libQt5Core.so.5 #9 0x00007fb33b972ee1 in QSGRenderLoop::handleContextCreationFailure(QQuickWindow*, bool) () from /usr/lib/x86_64-linux-gnu/libQt5Quick.so.5 #10 0x00007fb33b97aee4 in ??

Forgive me for asking, but are you sure this is due to the Nvidia driver packages or glx-alternatives? Andreas, you use KDE if I'm not mistaken. Are you seeing any issues? Do you need your user in any group to fix the root:video 660 problem on the device nodes? Kind regards, Luca Boccassi
