I've been thinking recently about resolution changes in wine/X. As I understand, this now works with UseXVidMode enabled, but I sometimes find it ugly; I run X at 1280x1024 and when I run game in 640x480 (fullscreen), X switches resolution. But as mouse cursor can escape from 640x480 "box", I can see the rest of my desktop (enlarged). I believe this is not how Win do it.
Even worse is when you run a game in desktop mode (let's say 1024x768) and game uses different resolutions (e.g. game: 1024x768, intro & main menu: 640x480).
So I've been wondering if you guys have already considered use of scaler. It would probably (in my opinion) look much nicer than current res switching and it would fill those black places in desktop mode.

Well, if you are in a coding mood, read the specs for the RandR extension and start coding in Wine. With some luck, you may even implement depth switching :-)

'Desktop' mode switching is another story. For that, it's pure Wine coding, no further use of X11 extensions are needed.

A scaler ? That's another possibility. But either it's in hardware or you will have a very slow Wine to play with (as the only stuff using resolution switching are games and, well, you do not want to get Wine's performance even slower that it currently is :-) ).

Depth switching isn't implemented by XFree at present, so it's resolution only. The other thing to bear in mind with R&R is that it moves panels around and things, beyond that I know nothing about it. I don't think integrating it would be too hard though.

Actually, you are right, in a sense. That isnt how windows does it. The game developers are the ones that decide how they want the in-game resolution to be done.. IOW: Yes windows handles the code to change resolution, but the game chooses the method..
I know for a fact that in some games, they change the resolution of the entire desktop (just alt-tab out of the game enough times and you will see your desktop in 640x480 or 800x600), while in others they do something else (my guess would be enlarging the game window)..
The reason you cant escape the game's window in Windows is 1 of 2 reasons (im not sure which is the one actually used, or maybe both apply).
The first would be because DirectX grabs the mouse and locks it into the dx-created window, although i think the 2nd one is the actual reason, this could be it..
The 2nd would be the way windows handles resolutions.. In windows, everything gets larger except for the desktop space.. Your icons and the taskbar take up more room, but you cant scroll the desktop to see everything (thats why if you are in 800x600 and have icons on the far right, when you go to 640x480, you can't see them anymore).. So no desktop scrolling in windows.
In X, everything grows, the area of the desktop, as well as everything on it, and you can scroll to see it all. Since wine doesnt always grab the mouse (and dxgrab doesnt always do what its supposed to), you are able to go outside the game window and see your desktop in the game's resolution, which isnt always what you want... Hopefully DXGrab works for those games..
Even worse is when you run a game in desktop mode (let's say 1024x768) and game uses different resolutions (e.g. game: 1024x768, intro & main menu: 640x480).

I agree here, this would be a nice bug-ger (feature)... ;) The problem would be that at first it would probably end up using a lot of magic numbers, until we figured out what went there and it probably wouldnt work for a lot of games until we tweaked the code, but it would be better than nothing.. Another benefit would be for apps that for some reason dont take up all of the desktop window even when maximized (i seem to remember there being a couple, but it's been so long I dont remember which ones)
