X server and RandR extension

When I try to get to the configuration of my monitor by using KDE Settings -> hardware -> monitor, I receive the msg: “Your X server is running the RandR extension at version 1.2 or greater which doesn’t have any configuration yet.” and it refuses to go further. What does this mean and where should I configure it? When I use Yast, Sax2 starts normally.

Can you tell us which openSUSE version you’re running? What graphics card do you have? The following command will help with answer to second question:

/usr/sbin/hwinfo --gfxcard

In order for RandR 1.2 to work, you need to have a graphics card which has a driver that supports this extension.

Of course! I use openSuSE 11.1 and Nvidia GeForce Go 7600 with the nv driver. RandR is version 1.2 Xserver is version 1.5.2 . Meanwhile I found a lot of information on X.Org Wiki - Home. I have the impression that it is Sax2 which does not know the new RandR version for configuring the xserver.

What does the following commmand report?

xrandr -q

Have you thought about installing the proprietary nvidia dirver?

It’s an unbelievable mess! The KDE applet says: “your driver is RandR 1.2 enabled but not configured”. I found the terms LVDS, VGA%d and DVI%d in the code of the driver, so I thought that it is ready for RandR 1.2 . When I try to configure this by hand in xorg.conf file and have it finally correct, the Xorg.0.log says that all the RandR options are not used and then continues saying “(==) RandR enabled”! And the kdm.log says: “Driver is not RandR enabled”.
They all contradict each other!

The xrandr -q command gives as result:
Screen 0: minimum 640 x 480, current 1440 x 900, maximum 1440 x 900
default connected 1440x900+0+0 0mm x 0mm
1440x900 60.0*
1024x768 60.0
800x600 60.0 56.0
640x480 60.0

I will have to install the Nvidia driver to get this working. Thanks anyway!

Don’t. NVIDIA drivers do not support RandR 1.2.

@gminnerup: I assume the OP is not actually interested in xrandr as such, but rather being able to take advantage of the better graphics performance of the nvidia driver, and possibly configure the monitor via nvidia-settings. As far as I understand, the recent proprietary drivers do have some xrandr compatibility.

But not 1.2 AFAIK.

What I want is to be able to have an external monitor on another resolution than the screen of my laptop. Most projector e.g. hae lower resolutions. I used the Nvidia driver on a previous laptop and I thought that that was possible. Now the system seems fixed in the clone mode.

I recommend you read this guide first. If you decide to install the proprietary nvidia driver, you can configure dual-head operation with the ‘nvidia-settings’ utility:

Configuring graphics cards/Dual Head Mode - openSUSE

Alternatively, you may wish to try the new open source nouveau driver with xrandr support (read nvidia section, first page):

openSUSE Graphic Card Practical Theory Guide for Users - openSUSE Forums

You might be better starting a new thread for further support if you choose to install this.

OK! I have enough information to try somethings out. thanks everybody!
