After a fresh Fedora 33 installation, my computer frequently freezes when I am using three monitors. When the freezing happens, I have to force it to shut down and only use one monitor for it to reboot. If I use three monitors, the reboot will also freeze.
I don’t have this problem when using Fedora 32 or just one monitor with Fedora 33. I guess that the NVIDIA driver shipped with F33 may work well with multiple monitors.
I am using GeForce GTX 1660 and the most recent NVIDIA driver (455.45.01).
