RHEL8 X.org crash
Today I experienced an X.org crash. I already disabled compositing in the past which increased stability a lot. This is the first crash since then. Some info about my system: GPU: 02:00.0 VGA compatible controller: NVIDIA Corporation GM107GL [Quadro K2200] (rev a2) kernel version: 4.18.0-305.10.2.el8_4.x86_64
