Query and change X server resolution??
 

Hi,
I am trying to either query my X server to know which res is it running and to change it to 1280x1024 if its not.
Can you guys help me? Below is my /etc/X11/XF86Config-4 file. It was written with "dpkg-reconfigure xserver-xfree86", and I think its ok, but I'm not sure its running in 1280x1024.
How do I figure it?
Thanks!

kernel is 2.6.5-1.k7

Re: Query and change X server resolution??
 

Check in the /var/log/XFree86.0.log for the way X detects it and change this in your config file.

That is the proper refresh rates according to this page I found with a quick google search.

An easy way to find the current res is to type xwininfo in an xterm. The cursor turns to crosshairs, click on the desktop. It's probably already at 1280x1024, since that's the only mode you have in your conf. It will also give you the color depth.

Hi philips and tux,
You guys kick big! With xwininfo I could determine the resolution was indeed 1024x768, and by editing the config file to the suggested syncs by tux, I could load it with 1280x1024. Very happy now!

Very thanks!!

Last question: why the reconfigure script defaulted to this values?
HorizSync 28-49
VertRefresh 43-72

Conservative defaults so they do not fry older monitors, that is one of the first things people should do after setting up X is change those to what their monitor actually supports. Good to hear you got it going BTW.
