how to save dual head setup?

English Applications
#1

Hi folks,

OpenSuse 11.3, 2 port Intel Ironlake ga, 2 identical monitors:

I can configure dual head mode in personal settings → display, but on the next login the setting is gone and its back to the default :-(. Thats pretty inconvenient.

Is there a cheat somewhere to save the dual head settings, or to modify the default accordingly?

In a NFS environment I would prefer to configure these settings in the system instead of the user home directory, anyway. If the user logs in on the neighbor PC with different hardware, then the settings stored in his $HOME are not valid.

Of course I checked Google for help, but without luck. Any helpful comment would be highly appreciated.

Regards

Harri

I agree that it would be nice to be able to make changes here persistent. Many users no longer have the xorg.conf file present, but for persistent dual screen setups, one needs to be created.

The other option is to use xrandr to configure your displays upon login.

The problem is not to find an xrandr command line (“xrandr --auto --output HDMI2 --right-of HDMI1”), but to tell the system to run this command before(!) running xdm.

I have patched Xsetup to get the xrandr command line in. Its just a dirty hack, of course.

I have the same problem with OpenSuse 11.3, ATI Radeon 3100, two monitors (DVI left, VGA right). Seems to be quite common but no easy solution. Harridu, could you provide a more detailed description of what you did, I am only medium experienced with linux. Anybody else knows a good solution?

If you just need this to happen after login (or for a particular user), then you can put the required xrandr line in ~/.xinitrc

Alternatively, it can also get added to ~/.profile instead.

BTW, the links posted above also outline how to achieve this (system wide) using the legacy xorg.conf approach too.
