I have recently changed my OS to Fedora-16 64-bit, I know that my Screen resolution is 1920x1200(From Previous OS on same Machine and other similar screens in my office). I have tried using xrandr -q Command to see the maximum Resolution available.

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1280 x 1024, maximum 1280 x 1024
default connected 1280x1024+0+0 0mm x 0mm
   1280x1024       0.0* 
   1024x768        0.0  
   800x600         0.0  
   640x480         0.0  

My desired Resolution 1920x1200 is not listed in here. But I have tried using xrandr -s 1920x1200 It has given following output Size 1920x1200 not found in available modes.

Can anybody help me in resolving this problems
