I recently installed Ubuntu and intended to use my 1920x1080 monitor with my 1440 x 900 laptop via HDMI, however, when I went into system settings to extend the displays I got this error:
The selected configuration for displays could not be applied requested position/size for CRTC 147 is outside the allowed limit: position=(1920, 180), size=(1440, 900), maximum=(1920, 1920)
I tried installing the proprietary drivers for my graphics card, which is an ATI Mobility Radeon HD 3650 and then changing my settings through the ATI Catalyst Control Center as one of the solutions online suggested, but this did not work.
The strange thing is the 1920x1080 screen seems to display 2 bars accross the top with 2 sets of wifi status icons, battery/email etc.
Any help would be greatly appreciated as I love the way ubuntu looks and can't wait to begin learning more about this OS.
