Nvidia graphics card: HDMI-connected monitor works fine, but not after screen lock/suspend

Hello,

one of my three monitors (connected via hdmi) behaves strangely since recent updates. The two connected via display port work fine. The HDMI-connected works fine upon start, but never restarts after suspend/screenlock. The issue can (sometimes) be resolved by plugging the HDMI cable and reinsert it.

Monitor works fine windows boot. I have two monitors of same type and have tried swapping cables and same issue with the HDMI.

Card: GeForce RTX 270
Nvidia version: 460.56
Linux kernel: 3.10.0-1160.15.2.el7.x86_64


(I do get errors like these when starting nvidia-settings)
ERROR: An internal driver error occurred
ERROR: nvidia-settings could not find the registry key file.

This sounds like a topic for the Nvidia linux forum which you can find here: https://forums.developer.nvidia.com/c/g ... /linux/148
