Hi, I'm running Fedora 9 and Fedora 10 Linux (prerelase) on IBM R52 laptop with Intel 915GM video chip.
I'm now using only one monitor - external 19" Samsung, but I would like if possible to also use laptop's screen.
Is it possible to setup dual screen with external moninitor as main monitor with resolution of 1280x1024 and laptop's monitor as secundary monitor (1024x768). I have been trying this using xrandr and also with configuring xorg.conf but with no success :(
If got the logic right I need one virtual screen with size of 2304x1024 (1280+1024). Laptop would be left to the main 19" external monitor so I need to have main monitor use offset of 1024 pixels. Have I made some wrong conclusions?
One thing is really puzzling me - and that is maximal virtual screen I see from xrandr output:
Screen 0: minimum 320x200, current 1280x1024, maximum 2048x1024
So is it even possible to do dual screen with these resolutions on Intel 915GM? Why? How?
Cheers, Valent.
$ xrandr --output VGA --auto --right-of LVDS xrandr: screen cannot be larger than 2048x1024 (desired size 2304x1024)

Valent,
according to what I read, e.g., here http://www.thinkwiki.org/wiki/Xorg_RandR_1.2#Notes_from_xserver-xorg-video-i..., the Intel GM cards before 965 only have 11 bit addresses for pixels and hence can only do 2048 pixels in either direction. Intel simply made a stupid design decision.

Under Fedora 9 I had a perfectly happy 1680x1050+1600x1200 (3280total) on two monitors. Still have the xorg.conf file for it.

Which intel graphich chip do you have and can you please share the xorg.conf?
Thank you.
Valent.

These are great links, thank you.
I looked and there is no intel read me in xorg usr/share/docs folders :(

The old xorg.conf is attached. Doesn't work under Fedora 10 - kdm.log starts filling up with (while waiting for the login screen to pop up). [mi] mieqEnequeue: out-of-order valuator event; dropping. [mi] EQ overflowing. The server is probably stuck in an infinite loop.
