Are you using NVIDIA OpenGL/video drivers?
Comment 2 Christoph Feck 2019-03-31 07:01:06 UTC 
No response; changing status.

If you are using NVIDIA OpenGL drivers, you must reboot after updating kernel and/or NVIDIA driver. Otherwise, a mismatch between kernel modules causes the NVIDIA driver to fail.
