I have a problem with my screen resolution - it's native is 1280x800 but I can get only two resolutions (from xrandr commend):
joanna@joanna-M51SE:~$ xrandr xrandr: Failed to get size of gamma for output default Screen 0:minimum 800 x 600, current 1024 x 768, maximum 1024 x 768 default connected 1024x768+0+0 0mm x 0mm 1024x768 61.0* 800x600 61.0
I've tried to add this resolution using cvt commend (this is what I get):
joanna@joanna-M51SE:~$ cvt 1280 800 1280x800 59.81 Hz (CVT 1.02MA) hsync: 49.70 kHz; pclk: 83.50 MHz Modeline "1280x800_60.00" 83.50 1280 1352 1480 1680 800 803 809 831 -hsync +vsync
I've tried each advise I found on the web but nothing solves the problem.
I am using a laptop:
Video card: ATI Mobility Radeon HD 3470
Screen (matrix?): Samsung LTN154X3-L03
Can anybody help me?
