Your drivers are broke.

Comment 2 Sefa Eyeoglu 2018-04-04 23:28:14 UTC

I guess that's expected. 
After installing a new version of the driver it crashes. This issue should be solved by implementing a fallback, so systemsettings can start with broken drivers.

Comment 3 Christoph Feck 2018-04-05 11:40:26 UTC

The fallback already is implemented in Qt since Qt 5.4, see http://blog.qt.io/blog/2015/01/22/introducing-the-qt-quick-2d-renderer/

The problem here is that the NVIDIA driver announces that it supports OpenGL, but then fails to provide a hardware context because of the version mismatch between the driver and its kernel module. Only a reboot can resolve it, or a fix from NVIDIA checking the version mismatch before reporting presence of the OpenGL support.

Comment 4 David Edmundson 2018-04-05 13:48:09 UTC

@cfeck see D7934 and D11722 on phab
