I am using Intel D2500 embedded board with HDMI and VGA ports. When I install opensuse 12.3 with XFCE DE I am unable to get display on both the monitors at a time. My Graphic Card Info.
I know this hardware has been problematic for some users, but some of the issues reported may well have been fixed with later kernel releases, so upgrading the kernel may be one option for you to consider.
Does the following execute without error? It may yield more info about the CRTC(s). Assuming it works, post the info here. Someone may be able to advise further.
xrandr --verbose
This XFCE page is Ubuntu-based but should still be relevant
Are you trying to connect 2 external displays concurrently, as well as the laptop (LVDS1) display? I don’t think that’s possible. Your xrandr output shows that the laptop display (LVDS1) is using CRTC 1 and the DVI-connected monitor is using CRTC 0.
It depends on the hardware I guess. It may be a process of trial and error. I’ve never owned a laptop with more than one graphics output. Maybe you can try turning on the DVI-connected monitor with
xrandr --output DVI-0 --auto
then turn off the laptop display
xrandr --output LVDS-0 --off
then (from the external monitor)
xrandr --output VGA-0 --auto
If that works, you may be able to generate a small bash script to simplify switching the required displays on or off.
When I try to set the HDMI(DVI-0) monitor the resolution more than 1024x768 it goes blank. ALso I want the desktop to be panned across two monitors not to be cloned.
do you mean that you achieved the same results as prior, or that you couldn’t get graphical mode to work … (the later would beg the question of whether you could get to console and if dmesg provided any clues as to what the issue was)
you may also consider just giving up on the gma500 driver and utilise fbdev (just add nomodeset to your kernel boot line in grub and the gma500 driver will be prevented from loading at boot)

Instead of --right-of you could use --above or --below to avoid
exceeding the max allowed size, though it may not be what you want.
Other than that you can set a higher virtual desktop size in xorg.conf.d
but from what I understand that will disable 3d and xv acceleration for
your card.
