I was just about to create a thread that is very similar to this one. So I'll just append your post with a post of my own. Staying in the realm of Blizzard games, I'm attempting to play Diablo 2. I have it working great, but this is what I would like to make happen... Right now I run Diablo 2 in windowed mode (passing in the -w command in the shortcut). This works fine but the largest window I can get is 800x600 since that's the largest resolution D2 has to offer. This is a little bit too small. I set the Wine virtual desktop to be 1024x768, and I've set wine to open in a virtual desktop from now on. Then I set D2 to run in fullscreen (passing in -d3d instead of -w). So what I was hoping would happen is that Wine would create a windows desktop that is 1024x768, then Diablo 2 would run in fullscreen (fill all of the 1024x768). This didn't happen. When I start D2, Wine starts up and is 1024x768. As soon as D2 boots up, even though it's in fullscreen, Wine shrinks itself down to 800x600 to match D2. I get D2 in a window still, tricking it to be "fullscreen" in a virtual desktop. But why does Wine resize it's resolution?! I'm basically trying to get D2, in Wine, windowed, at 1024x768. Is there a way to do this? To make it simple, is there a way to make Wine stop snapping it's size to the application inside it?
