Asked by Jonas

Hello,

I was able do this with xinerama on previous Ubuntu versions and starting from 7.10 settings in xorg.conf not working anymore. Every time when I connect projector to computer my monitor switches to projectors resolution.

Hello,

Newer versions of Xorg support dynamic monitor support via the XRandR extension instead of XINERAMA, so while this is an unexpected change, it is not a bug. You may have to update your /etc/X11/xorg.conf configuration file; a good approach may be to back up your old xorg.conf and have the X server generate a new one to start with.

For more information see:
    http://www.x.org/wiki/Projects/XRandR
and in particular, the link for configuring an Intel server for Dual Head use.

Hello,

So then must be something done with screen resolution settings window. If I set for each of monitor resolution and press apply I expect to happen something else not just blink of screen :) There should be some message that I must edit xorg.conf and read about XRandR.

You can also use URandR by Alberto Milone

http://www.albertomilone.com/urandr.html

It's a GUI to XRandR known to work with Intel and ATI cards

Can you help with this problem?
