Hi,
I have trouble with xrandr and external monitors. I have not found any solutions to my problems yet and hope some one here may have a solution.
First problem.
When I switches on the external VGA it also becomes my primary monitor, I want to use the laptop monitor as the primary since I mostley use the external for presentations. The only suggestion I have found for that problem is to change the BIOS settings but no luck there.
Second problem.
I am not able to set the external resolution to 1920x1200, which works fine in Windows XP. I have tried to patch the BIOS with 915resolution with no success and a bunch of modelines in xorg.conf. If I try starting X without any xorg.conf and the external monitor plugged I get som strange cloned mode, but when I do this the driver indentifyes my external monitors resolution to 1920x1200. But when doing so my keyboard does not work any good.
I use the xf86-video-intel 2.2.1-3 package and have a i950 chip (thinkpad x60s) with libxrandr 1.2.2-1 and 915resolution 0.5.3-1
Best regards and thanks in advace

I have had some progress in my work. My first problem seems to be a problem with the window manager and not related to xrandr.
But still no progress with the resolution problem.

Now I have also found a solution to my other problem. Removing some lines from my xorg.conf did the trick.
Changing Device and Screen to this did the trick:
Section "Device"
Identifier "card00"
Driver "intel"
EndSection
Section "Screen"
Identifier "Screen 0"
Device "card00"
SubSection "Display"
Virtual 2048 2048
EndSubSection
EndSectionOffline
First, try to get rid of the 915resolution thing. xf86-video-intel doesn't need BIOS patches anymore. That might interfere with xrandr.
Second, you can set your external monitor to be to the left, right, bottom or top in relation to the other. check out: http://www.thinkwiki.org/wiki/Xorg_RandR_1.2
Hope that helps.
