I’m using Manjaro i3 on a Legion laptop with switchable graphics (AMD/nVidia) and I’m trying to get the display to automatically change to an external monitor whenever I connect it.
I already know how to use xrandr to do this manually, so now I’m trying to get the script that I wrote to be run automatically whenever a HDMI connection occurs. According to the documentation on xrandr - ArchWiki I’d need to use udev to detect the HDMI connection event, however when I run the command udevadm monitor there is no event registered when I plug or unplug the external monitor through HDMI, so I can’t progress any further to identify the device to write a rule, and I also wouldn’t expect it to work anyway since the event is not detected…
Does anybody know what could be going on?
These are my machine’s specs (from the inxi command):
