No HDMI output on either free or non-free

Sorry to post another one of these, I ran through similar posts but nothing I could follow seemed to help.

Per another thread, I uninstalled the non-free driver and brought the system back up with the monitor connected, but no change. The monitor is seen by the system, but does not receive output.

This is my first shot at Manjaro with a new machine, hoping to avoid going back to Ubuntu :sweat_smile:

So this is a laptop right? I think NVIDIA has not fixed the HDMI port output with AMD cpus in hybrid mode (the mode you are right now)

Assuming you have the non-free drivers,just to be sure,type in a terminal

nvidia-smi

and if there is a XOrg process in there,then yeah you need to switch.

For that you need to install optimus-manager

pamac build optimus-manager

when you install it,be sure to follow this

Manjaro ships with a default configuration for SDDM (the default login manager for KDE) which overrides some keys needed by optimus-manager. To use optimus-manager, you need to edit the file /etc/sddm.conf and simply put a # before the line starting with DisplayCommand and the one starting with DisplayStopCommand .

When you done,reboot and now you can switch cards.

optimus-manager --switch integrated
optimus-manager --switch hybrid
optimus-manager --switch nvidia

Switch to nvidia mode,logout and login and your HDMI port should work.
