Unable to change screen resolution


Hello !

I would like some help for setting my screen resolution on a laptop under Mandrake. Everything seams to be well configured and the logs looks correct to me but the problem is that I can't change the resolution with the Mandrake utility or by editing XF86Config-4. The screen is automatically detected with it's correct resolution. I would like to change the resolution because wine can't run in full screen and I only have a little window surrounded by black.

I have been looking around to see if the question had already been answered but I found nothing about this.

Control-alt-keypadplus or Control-alt-keypadminus switch between your available screen resolutions. But the Wine issue is a little more complex than that - X automatically creates a "virtual desktop" the size of your maximum available resolution, so if you are at 1600x1200 for example, and switch to 800x600, you can scroll around the desktop using the mouse. Some games won't take over the whole screen in Wine like they're supposed to, so you may have the same scrolling behavior at lower resolutions, even if the Wine program is filling the screen.

The keypad-trick doesn't work but thanks anyway. When I set a resolution and restart X, it doesn't change anything and the resolution remains the same. For Wine, I only have a tinny portion of the screen that display something.

Sorry if I am not clear enough.

I have a related question that I'm hoping someone can answer.

I have a keyboard with no keypad, so I can't seem to change my screen resolution.
Is there some reasonable way to remap the "Keypad Alt +" and "Keypad Alt -"
functionality to something else? I'm using the Debian woody release.

Thanks,

To change the ctrl+alt+keypadPlus keys do the following:

Find the key you want to map to change the resolution. (Try using the xev command---it will tell you the keycode of a key you press.) For example I have a useless "email" button on my ThinkPad, which has keycode 236.

Map it. Use the command
$ xmodmap -e "keycode 236 = XF86_Next_VMode"

Test it. Press the button you just programmed. If it works, you can also try mapping another key to XF86_Prev_Vmode. (This works in XOrg too, BTW.)

Make it permanent: create a file called .xmodmap in your home directory and put the keycode command(s) into it. See man xmodmap for details. Most X environments will load this map automatically.
