My primary monitor just started to malfunction
It would show a white picture with vertical bars on near middle right of the screen. Had to to use an old vga monitor not fully compatible with my current software which caused me alot of annoyance. Had to uninstall old nvidia driver as it would not detect this monitor correctly, installed open source alternative, and added a script that sets correct login resolution and rate as automattic detection would not set correct one resulting in monitor showing an error. Not mentioning display settings showing modes not properly supported it.
