The Problem
A while back, I set up a home-server on an old spare PC running Debian 13. The install is (mostly) headless, so I don’t have Wayland or X11 installed, and don’t plan to do so.
When I plug a Monitor into the machine itself to do some work on it, I can’t get any output on my monitor. If I then reboot, the Monitor works as expected, until I unplug and then later re-plug it. The graphical output is on a GTX 1050Ti, and my Motherboard has no graphics port I could use to test / fall back to.
Order of Events
I boot up the server with a Monitor plugged into my GPU’s HDMI or DP output, and I get an output as expected. I can progress past the bios, grub, as well as to the login, and use the machine as normal. I then unplug the monitor, and plug it back into on of the ports, but get no output. The monitor itself output something like “No signal”, not just a blank output.
What I tried already
- I tried switching
tty‘s withCtrl+Alt+F1-12. - NVidia drivers are installed and working correctly (tested via
nvidia-smi), andmodesetis already set toY.
Possible solutions not fitting this case
- X11 can force a rescan of displays with
xrandr.
