Dual monitor on laptop with ATI

p41elvis · 03-01-2006, 10:59 AM

I will try the clone setting, but I think that if I do that I get the exact same desktopview on my ext. monitor. I want to display differenct content on it.

I can't seem to find the Xinerama and Dual Head options you talked about. Where are they exactly? I usde KDE 3.4 and Mandriva 2006.

Alright, we I use the clone setting my external monitor displays the same content as my laptop monitor. Only I can "move the screen" on my external monitor around because the resolution is bigger then it can actually display.

About my problem when I use the horizontal option: Linux is then displaying content outside the boundry of my external monitor screen. I it showing the rightmost icons of my desktop so far to the right that I can't see them anymore on my external monitor.

It has been quite in this thread for quite some time now. I have experimented a bit further and came to this configuration which actually gives two different deskopts in two different reso's on my two screens. The only problem is that they are not usable. I see the blue color of the background and the light gray of the taskbar, but that's it. The mouse because a big funny looking square, so the screens are unusable. Here follows my current xorg.conf file:

The commented (#) piece is the configuration for a big desktop. This actually just streches the desktop to two monitors.

Does anybody know how to get the dualhead configuration to work because now the screens are unusable...

Best regards,
