If you are trying to connect 2 monitors (HDMI + USB C), you might find that only USB C and the laptop monitors is working in Fedora 32. After I search around, here is the simple solution. Create a file (any file name end with extension .conf) under folder /etc/X11/xorg.conf.d. I name it 11-nvidia-prime.conf. (Copy from ubuntu). Enter the lines below and reboot.  [root@localhost xorg.conf.d]# cat 11-nvidia-prime.conf Section "OutputClass"     Identifier "Nvidia Prime"     MatchDriver "nvidia-drm"     Driver "nvidia"     Option "AllowEmptyInitialConfiguration"     Option "IgnoreDisplayDevices" "CRT"     Option "PrimaryGPU" "Yes" EndSection I believe this solution should be working for Fedora 25 and above. Leave me a message if you have question.
