However, this tip does not work for GNOME 3, or other systems that only have one X screen for multiple outputs (monitors). It would be nice to have a fix for this, but I guess that is a matter for SDL? If so, I'm happy to submit a suitable bug report/feature request to SDL. In the mean time, it would be nice to document this problem, for example, by adding to the FAQ answer: > Note that if you use GNOME 3, or another system that combines multiple outputs (monitors) into a single X screen, this fix won't work. Of course, it would be even better to offer a workaround. Unfortunately, it's a bit tedious: the best way I can find is to switch off all but one display, then start ScummVM, then after quitting ScummVM, switch the other displays back on, and assign them their correct relative positions in the X screen. I wrote a script to automate this process, which I append below: ~~~~ #!/usr/bin/env python3 # Run a command on a single display output # (Working around the lack of a way to ask SDL for a single output) # © Reuben Thomas 27th April 2016 # Distributed under the GNU General Public License version 3, or (at # your option) any later version.
