Problem running in high resolution

[MAXDDARK]

I use Ubuntu resolution1024x768.
If I run regnum in higher resolution the screen is two big, meaning that I see only about 2/3 of the screen.
I want to run the game in the highest resolution 1280x1024 without changing my Ubuntu screen resolution.

I have ATI 9800 Pro videocard.

how can I do it ?

what is your current resolution? you can type xrandr to find out

EDIT: nevermind, i didn't understand your post fully; the short answer is you can't, a program can only have as high resolution as your workspace currently has, if your workspace is in 1024x768 and you select 1280 for regnum, you will get a 'virtual' workspace where you have to drag the mouse around to see the entire workspace

you must run the workspace in 1280 in order to be able to run regnum in 1280; however, assuming you start X in 1280, you can then use xrandr to set your resolution to 1024, thus giving you your regular 1024 resolution for every day work, and then you can switch to 1280 when you want to play regnum

That's right. Regnum (or any other program) can't use a resolution larger than the maximum resolution configured in the X Server.

ok, Thanks for the answer.
