Reseting X resolution

[Luis Marques]

Hello all,

I like to test some DirectX applications from time to time. Problem is that 
they succed long enough to set the resolution but after that fail. I can 
Ctrl-C the application and resume working but it's not very practial to work 
on a 320x200 desktop...

How can I restore the resolution? Is there any standard way? Should I just 
write a few lines of SDL code to set the resolution?

Thanks,
Luís Marques
