double screen in ubuntu 12.04?
- by johan
I am using ubuntu 12.04 and my video card is ATI Radeon 5000. I cannot use double screen (extended version). I get this error
The selected configuration for displays could not be applied
requested position/size for CRTC 148 is outside the allowed limit: position=(1280, 0), size=(1280, 768), maximum=(1440, 1440)
I tried all display settings but it does not work.
Some outputs from the system settings:

I would appreciate any suggestions how to solve the problem. Thank you
