    Default how to get two monitors working in suse 12.3 and kde desktop platform, intel HD Graphics 4600

    Hi everyone!
    I have two monitors connected with DVI and VGA, and my computer has DQ87PG motherboard and Intel HD Graphics 4600. I have a problem of extending the screen between these two monitors, but all that happens is one monitor is automatically a mirror of the other. I am currently using suse 12.3 and KDE desktop platform. One of the suggestions from previous similar kind of posts was to use the xrandr to set them up, but this is what i get as i type it on the console:

    xrandr: Failed to get size of gamma for output default
    Screen 0: minimum 1920 x 1080, current 1920 x 1080, maximum 1920 x 1080
    default connected 1920x1080+0+0 0mm x 0mm
    1920x1080 77.0*

    Can anyone please help me on this.

    Sorry, but you posted this in "How to use the Forums".
    Your question has imho nothing to do with how to use the forums.

    This will be moved to Aplications and is CLOSED for the moment.

    Try usin KDE to see if your second monitor will auto-detect and -configure.

    Applauncher button > Configure Desktop > Display

    What is the output you get for the following two commands?
    Code:
    cat /proc/cmdline
    Code:
    /sbin/lspci -nnk | grep VGA -A2

    The DRM/KMS kernel driver appears not be loading.

    Given Haswell came out post openSUSE release, try updating to a newer kernel. Suspect your issue will be resolved then (and in future releases)

    Nah, won't matter -- that's just a frontend to xrandr and it (xrandr itself) is already indicating there is an issue: "xrandr: Failed to get size of gamma for output default" -- that message points to a potential DRM/KMS issue ... the OP's later follow up shows no DRM/KMS driver is loaded.

    You might want to try to install version 11.x, in my case(s) 11.3 works for "this situation". I loaded version 12.3 on my laptop with all updates performed, (1440 x 900) and an external monitor 1920 x 1200 (VGA) and experience similar problems. Wipe Drive, and Re-installed 12.3 - similar not identical problems reoccurred on the re-install. Seems there is a issue with version 12.3 on two monitor configuration (Display, Size & Orientation, Resize and Rotate your Display).

    Note version 11.3 works with two monitors on an AMD laptop, and Intel laptop ( 1440 x 900 -internal, and 1920 x 1200 external-VGA ).

    Version 12.2 works on my desktop, multiple monitors with no display problems, two monitors both VGA 1920 x 1200.

    I prefer to test new versions of OpenSuse on my laptop before I upgrade my desktop.
