I was trying to get the apple2gs driver to reset with the default bindings of F12 = reset and CTRL = ctrl with OpenApple = LALT and it doesn't work with xorg. To xorg, CTRL+ALT+F12 means switch to virtual terminal 12 which drops me into a text screen and I have to hit CTRL+ALT+F2 to get back to my normal xorg session.
I tried switching reset to PgUp but that didn't help. CTRL+ALT+PgUp doesn't seem to work.
CTRL+OA+ESC is supposed to bring up the control panel but I couldn't get that to happen.
There's also CTRL+ALT keys that get grabbed to do things like move windows around (for example CTRL+ALT+NumPad0 will minimize your existing window).
It's also annoying to accidentally hit the windows key and have Ubuntu's search box come up.
I'm wondering if there's an easy way to give mame priority over these keystrokes.
Or is reset handling not working on the apple2gs driver? I was able to map Reset to C and then reboot the apple2gs with CTRL+C. This worked on mame196 (an old version I had handy) but not on mame204.
