Dual Monitor Xorg Configuration with different resolutions

[terry84]

Hi all,
I have been tasked to set up 2 monitors on SUSE Linux Enterprise that are a clone of each other, but each displaying different resolutions. The primary display has a max resolution of 1024x768 while the secondary display has a max resolution of 800x600.

The problem comes when the secondary display shows a "cropped" version of the desktop. Is there anyway to show different resolutions on each display while maintaining the proper desktop look?

I have attached the relevant portion of my xorg.conf.

Thanks in advance.

Hi. Anyone able to help? Or am I not clear in my question?

[deano_ferrari]

It is not possible to have clone mode at two different resolutions, without cropping occurring, as the desktop is sized to the primary display, however you may be able to optimise it to better cope with the lower resolution of the second display.

This graphical explanation may be helpful (or not)

Thanks for the link. It was useful.

I guess there is no way for this then.

You could set the monitors to a common resolution.

But think about it you want to put 1 gal into a quart jar.
