"Big screen" with different resolution?


Hi folks,

I am using "big screen" on two monitors, one is the wide screen LCD on my laptop (1280x800), and the other is the desktop LCD (1280x1024).
The video card installed on my laptop is ati radeon mobility 9700 (recognized as 9600 in Ubuntu 5.10 preview), and I have the closed source driver from ati installed (8.16.20-i386).

The installation and configuration went smoothly, but now I can only set both monitor's resolution to 1280x800, and the big screen has the 2560x800 as a result. Due to this weird resolution, the bottom of desktop LCD is chopped off.

Please guide me a way that I can use big screen and set two monitors to have different resolution.

You help is greatly appreciated.
Regards,
James

1. What does "big screen" mean?
2. How should the system recognize which monitor is connected?

"Big screen" is just a term provided in ati's driver through out the configuration phase.
Big screen essentially means your desktop extends from one screen to another, like you are using two monitors to display one big desktop.
I don't know how the system recognize which monitor is connected by far, but it does work smoothly though.


Waiting for you advice, cheers.

Have you tried adjusting the xorg.conf or XF86free.conf files? There should be a setting for each displays resolution.
Not sure about ati, but nvidia drivers you can assign which monitor is connected where.

As we set it to "big screen" option, there is only one monitor exists in the xorg.conf, I have the resolution set to 1280x800. But the real resolution is actually (2 * 1280)x800

Due to I have a wide screen and a normal one, the gui just screws up whenever I try the "dual head". It's like the wide screen display normally, but the normal LCD only use part of its screen to display, and even worse, the x-window seems to be corrupted somehow...

Thanks for your kindly help, but my problem is really that I am using two monitors with different <width:height> ratio, one is true 16:9 LCD and the other is normal 4:3 one.
If I go for the "dual-head" mode, both screen are intefered by each other. If I go for the "big-screen" mode, the 4:3 one will have some portion made invisible.

Does anyone get the same problem?

Thanks in advance,
James
