Disabling virtual screen mouse scrolling in X?
OK, so you probably all know how if you run X at a low resolution, and you have a larger virtual desktop, you can scroll the screen around by moving your mouse to the edge. The virtual screen can be sort of disabled by commenting out the "Virtual" lines in XF86Config, or by setting only one screen resolution (1600x1200) in the "Modes" section (though it's still there, at the max resolution listed in "Modes"). Anyhow, to the point:
I want to run some games in Wine at full-screen, 800x600, say. They run at lower resolution than my only "Mode" in XF86Config; they fill the screen, but once again, moving the mouse to the edge causes X to scroll around the 1600x1200 desktop, and my game to go off the edge. The "DXGrab" wine config option does not prevent this from happening, nor do any other settings I've tried. I've determined with near-certainty that there are no wine configuration options that will fix it; presumably DXGrab is broken for some situations, so it's time to find a workaround.
From what I can tell, there's no way to completely disable the presence of a virtual screen; it's going to be there, at whatever the highest resolution listed in "Modes" is. All I need to do is find a way to disable the scrolling that occurs when the mouse hits the edge. Anyone know of a way to do this?
