No HDMI signal if monitor not connected at boot

Hi all,

I’m using a KVM switch with my Manjaro install. If I start it up with the monitor unconnected, I don’t get an HDMI signal after switching to it with the KVM. Is there a way I can redetect the HDMI connection?

Hi and welcome :wink:

I guess you have to configure the xorg.conf manually. I think it tries to find a mode itself and failed.

Could you post Xorg.0.log and your xorg.conf or /etc/X11/mhwd.d/nvidia.conf ?

Thank you :wink:
