Wrong monitor chosen as main one.

xushi · 01-15-2007, 05:15 AM

I'm trying to setup my external monitor so that it has an extra screen to which i can drag/drop windows on to. I've almost got that to work... Using gentoo's non-twinview tutorial in http://gentoo-wiki.com/HOWTO_Dual_Monitors

I've got two screens (though for some reason i can't drag/drop in them), but my main problem is that whatever i do, the external monitor is always set as the main one, instead of the laptop's monitor. Here is part of my configuration.

mymon: the laptop's monitor
iiyama: the external monitor

myvga: the laptop's vga
myvga2: the external monitor's vga

screen 0 : the laptop's screen
screen 1: the ext. monitor's screen.

Code:

I tried switching over Screen 0 with 1, using LeftOf instead, etc.. but nothing worked. It always chooses the external monitor as the main one.

I'm running Xorg 7.1 on Gentoo with Nvidia 1.0.8776.

Any help is appreciated. Thanks.
