My current installation of ubuntu is running on 1024x768, however my monitor's optimal res. is 1366x768 which is successfully attained on the dual boot windows XP.

So i tried a plethora of ways to try and gain the 1366 resolution, mainly with xrandr and ran into a huge load of troubles following several guides from several websites.

Currently my xrandr looks like this:

    xrandr: Failed to get size of gamma for output default
    Screen 0: minimum 640 x 480, current 1024 x 768, maximum 1368 x 768
    default connected 1024x768+0+0 0mm x 0mm
       1024x768        0.0* 
       800x600         0.0  
       640x480         0.0  
       1366x768       59.9  
      1368x768_60.00 (0x18a)   85.2MHz
            h: width  1368 start 1440 end 1576 total 1784 skew    0 clock   47.8KHz
            v: height  768 start  771 end  781 total  798           clock   59.9Hz
      1366x768_60.00 (0x18d)   85.2MHz
            h: width  1368 start 1440 end 1576 total 1784 skew    0 clock   47.8KHz
            v: height  768 start  771 end  781 total  798           clock   59.9Hz

Any even though it says 1366x768, when i try to set it runs my into a error, when i try to set it up via Display GUI it says maximum is 1024x768 This is when i get when i use xrandr-s

aayush@aayush-desktop:/var/www$ xrandr -s 1366x768
Size 1366x768 not found in available modes

I highly appreciate any help in the matter

Try xrandr -s 1366x768_60.00 instead. –  dobey Sep 10 '13 at 17:17
