So, I have an AMD APU with an integrated Radeon, VGA and HDMI outputs.
I'm currently using the HDMI output with a DVI adapter for my main monitor, and I'd like to add a second monitor using VGA.
For some reason though, when I plug in the second monitor, both screens go black until I reboot.
If I plug in my main monitor with both connections though, it works fine. I can set it to "duplicate desktop" and everything with no problems, but then I unplug the main monitor from the VGA port, keep it plugged into the HDMI, and plug the second monitor back into the VGA and the screens both go black.
