Question Command to change screen resolution?


Is there a command in Fedora to change the resolution instantly?
I know "krandrtray" let's you choose the resolution you want, but I need a command that will accept the resolution as a paramater, and change the resolution instantly. Like "programname --resolution 640x480"
I'm using it for a Starcraft startup script, because the resolution has to be 640x480 for Starcraft to run.
Thanks.

Not sure of a command line way of doing this, but you can use crtl-alt-(keypad +) or ctrl-alt-(keypad -) to cycle through the resolutions without restarting X. On my laptop, this means ctrl-alt-Fn-+ or ctrl-alt-Fn-

Are you sure that cycles through the resolutions?
I was under the impression that it just zooms in or out.

The resolutions defined in the config ARE the zooms used, by changing the resolution. The desktop virtual resolution is not changed, and can't be changed AFAIK (once X is started, it can be set in the config however).

If it can't be changed, then how does that KDE program (krandtray or something similar) that comes with Fedora Core 1 change it? Or does that just zoom?

I'm not familiar with that program, but don't use KDE very often. Its not installed on my machine currently with that name.

The desktop settings module of the Control Center does allow changing resolutions and refresh rates however. I wasn't aware of this until I just went looking. I don't know how it does this, but the X server doesn't appear to restart, so either they are dynamically resizing the virtual desktop size, or they are simply locking the window manager's useable size (leaving the rest of the virtual desktop space unused but still out there). Just a guess of course. The answer is in the code if you've got time to find it. :-)

Ok, thanks.
The program is named 'krandrtray', btw.
