This is driving me crazy. Every single time I boot Ubuntu (24.04 LTS release) with three monitors connected, my computer freezes at the login screen. I can't move my mouse, ctrl+alt+F1 thru 6 do nothing, and so on. All I can do is reboot by holding the power button.
The second I unplug my third monitor and reboot, the issue goes away. Can anyone help? It's interesting to note that this is actually the reason I switched to Ubuntu; I was running debian but got this issue and jumped over in hopes of a fix. I don't think it's a hardware thing as the monitor works fine when on the desktop and boots font in windows.
GPU is an RTX 4070, proprietary nVidia drivers installed.
Thanks!
