Thank you for taking the time to report this bug and helping to make Ubuntu better. Please answer these questions:

* Is this reproducible?
* If so, what specific steps should we take to recreate this bug?

This will help us to find and resolve the problem.

I am running via nx (nomachine v3.?), I have reported other (related?) issue 971482 / 970723

[Kiall Mac Innes (kiall)]

This seems to be affecting 12.04 beta2 now as well...

[Nathaniel W. Turner (nturner)]

To reproduce: System Settings... > Displays. I get dialog indicating "Could not get screen information" "RANDR extension is not present". Choose Close button. Crash.

My setup is an Nvidia Quadro NVS 450 with 3 monitors (and thus Xinerama), so the RANDR extension is not expected to be present. I don't, however, expect the configuration app to crash.

[Sebastien Bacher (seb128)]

Thanks, that's an useful information ... is that already the case for others who get that issue? What video driver,screen setup do you use?

[Paul Meredith (paul-venture-its)]

I am also running Nvidia Quadro NVS450 with Xinerama and Mosaic enabled. Then RANDR extention is not running as expected. I am using the latest Nvidia Drivers (295.40) and Ubuntu 12.04 Beta2. 1 am using 4 Screens (1680x1050) in a 2 x 2 configuration.

[Mario Jäckel (mario-jaeckel)]

I am running Ubuntu 12.04 LTS -Release amd64(20120425) with a Nvidia Quadro NVS 295 graphic card. Xinerama is enabled with two identical monitors. RANDR extension is missing on system.
I am using the 295.49 printed out from nvidia x server settings. X says I'm using 295.33 driver as printed out in /etc/X11/xorg.conf

[Goekce (leuko)]

I can also confirm it with an Nvidia Quadro NVS 450 with 304.22 beta drivers regardless of using Xinerama or not. Also using Ubuntu 12.04.

[Sebastien Bacher (seb128)]

the code has been rewritten since which means that bug isn't valid anymore
