I have one monitor that I use for both my PC (via VGA) and my Linux machine (via DVI). I just use it for one computer at a time, by pulling out the not needed cable and plugging in the required one.
But when I unplug the DVI, after starting Linux, and then plug it back in, I just get a black screen and I have to reboot the Linux machine to get anything to happen.
How can I get it to work properly? ( I don't get this issue reconnecting to my Windows PC)
