My allegro program runs fine in full screen mode, but after I exit the program, my desktop screen resolution is messed up. I was under the impression that running allegro_exit(); would revert the screen resolution back to what it originally was.
I was just wondering if anyone else has had problems like this and what they did to fix it.
I'm running it on Linux Mint 13
First off, hopefully you are at least running Allegro 4.4. But even then, I would highly recommend switching to the 5.0 series. Version 4 is essentially past end-of-life, and as operating systems change, it becomes less likely to work reliably.
That said, you could try explicitly calling set_gfx_mode(GFX_TEXT, 0, 0, 0, 0) to try to cleanly exit the full screen.
Also, you'll have the fewest problems if you set the same mode as the desktop. e.g.:
int w, h;
get_desktop_resolution(&w, &h);
set_color_depth(desktop_color_depth());
set_gfx_mode(GFX_AUTODETECT_FULLSCREEN, w, h, 0, 0);
And perhaps GFX_XWINDOWS_FULLSCREEN will work better. Or maybe GFX_XDGA2 running with root permissions. If all that fails, you're likely stuck using windowed mode.
