I'm running Ubuntu 12.04.2 LTS x86_64 with two mismatched monitors: one, a laptop @ 1366x768 native, the other an Asus @ 1920x1080 native res. How can I enter fullscreen with mednafen displaying on just one monitor, leaving the other one untouched? The problem with just hitting atl+enter after booting up a game normally is my large display shrinks and both monitors mirror (and stay mirrored afterward).

This is just a pain and passing arguments like -pcfx.xres 1366 -pcfx.yres 768 from a bash script just results in the game being displayed across both monitors. If anyone has some tips that I could learn from, it'd be appreciated.

Edits: if it helps, compizconfig is set to detect my outputs (display settings).

Here is the output when running a game via bash script

Initializing sound...

Set these environment variables as shown, in your bash script, before running mednafen, and it will full screen only on the primary display.


You may also need to update the configuration in ~/.mednafen/mednafen.cfg to not have the very large resolution specifications set, had they been set to the large values previously.

Hmm, still results in mednafen spanning both monitors. – DiabolicalClaptrap Mar 17 '13 at 22:53
I appreciate the help, but I'm still unable to work this. Like you suggested, I edited x and yres in mednafen.cfg.. no go. – DiabolicalClaptrap Mar 19 '13 at 19:47
Ok, I went ahead and fixed it myself. Turns out I had to set pce scaling options to their default values. Works great. Thanks. :) – DiabolicalClaptrap Mar 19 '13 at 20:11
