Dual-head: How to swap Primary/Extended screens:
Current : Primary screen = VGA-Monitor 1 and Secondary/extended screen = DVI-Monitor 2
Target : Primary screen = DVI-Monitor 2 and Extended screen = VGA-Monitor 1

My configuration:

Monitor 1 (VGA) (primary screen) ---- (Opensuse 11.4) ---- (DVI) Monitor 2 ACER (secondary screen)

Videocard Radeon Ati Radeon 9200 Pro RV280
Desktop: Gnome 2.32.1
OS: Linux OpenSuse 11.4 - Current Operating System: Linux linux-yabh 2.6.37.6-0.7-default

xorg.conf.d/50-device.conf
Section “Device”
Identifier “Default Device”

#Driver “radeon”

Required magic for radeon/radeonhd drivers; output name

(here: “DVI-0”) can be figured out via ‘xrandr -q’

#Option “monitor-DVI-0” “Default Monitor”

EndSection

Is there also some kind of manual or user guide which contains how to configure dual-head related issues?

Please give me your opinion.
Thank you for the effort

I’m not a Gnome user, but isn’t there a Gnome Control Centre > Monitor Preferences utility that can help you configure dual screen operation?

Otherwise, you could consider using a graphical front-end to xrandr - eg grandr or lxrandr

Grandr Applet Home

Thank you for the suggestion.
[1] Gnome has the possibility to choose a monitor as default, but it gives an error: could not set the default configuration for monitors.

[2] Then i choose xrandr --output DVI-0 --primary. With this command i am able to set a monitor as primary monitor (see also [ubuntu] Set primary monitor - Ubuntu Forums]([ubuntu] Set primary monitor)).

I will inform Gnome community for this error.
