Hello,
I'd like to know if there's a possibility to disable the auto-detection of a specific monitor / output.
I explain my case, i have three monitor & a KVM PCI-Passthrough setup for gaming.
When i start my vm i turn off my principal monitor via a libvirtd hook and it switch to windows. My second screen have a KVM switch between arch GPU & Windows GPU Third screen only on arch.
When i switch the KVM for the second screen, Xorg re-detect my primary screen and turn it On, but i can't see all my windows because the monitor is still switched on the Windows GPU.
My arch GPU is a GTX980 running on proprietary drivers.
You could write a script / set of scripts that issue the appropriate xrandr commands to enable / disable that monitor output. For example, I have the following bash aliases on my laptop to enable / disable the VGA output: alias extendvga='xrandr --output VGA1 --auto --right-of eDP1; xrandr --output eDP1 --primary' alias retractvga='xrandr --output VGA1 --off' --Sean
