fullscreen doesn't work

i tried to start some wine game in fullscreen. that game needs 640x480 resolution, but sax for some reason doesn’t have it. i tried to edit xorg.conf, but sax refused to accept this resolution (it wasn’t in list). so maybe there is some application that will emulate 640x480 for wine and interpolate it on my native resolution.

Try adding a few modelines to your xorg.

Type “gtf 640 480 60” into the console and paste the modeline generated into your xorg. Restart x and try the game again.
