How can I add additional resolution for my screen?

Question

I tried to launch a game (GTA San Andreas) on wine.

GTA showed Cannot find 800x600x32 video mode and closed immediately.

The Computer I currently have is a Lenovo IdeaPad G510, with Intel HD Graphics 4600 graphical processor. I didn't change anything in wine settings. My OS is Debian 7.5 (wheezy).

I googled and got the error "Cannot find 800x600x32 video mode" is caused by my graphical card not supporting resolution requested by GTA resolution.

I ran xrandr command and got:

xrandr: Failed to get size of gamma for output default Screen 0:
minimum 1366 x 768, current 1368 x 768, maximum 1368 x 768 default
connected 1368x768+0+0
0mm x 0mm    1366x768        0.0      1368x768  0.0*

As I can see 800 x 600 isn't an available resolution for my screen.

• Is there any way to add it?
• Should I edit Xorg configuration file, etc. ?

Answer 1

Is Grand Theft Auto 3: San Andreas's 800x600x32 resolution just for the menu to work? If not you can emulate such a window using Wine and then in the game's menu set your specific resolution.

If yes, then you may also try using xrandr's scaling arguments:

--scale xxy
        Changes the dimensions of the output picture. Values superior to
        1 will lead to a compressed screen (screen dimension bigger than
        the dimension of the output mode), and values below 1 leads to a
        zoom in on the output. This option is actually a  shortcut  ver‐
        sion of the --transform option.
