Yes, I am using 'xrandr --output DVI-0 --mode <mode name>' most of the time. I
stopped using '-s' :-)

Now my observations are:

 -checked the EDID info, and found that the MAX supported resolution is
'1280x1024'. And I can successfully change the resolution upto that.

- where as my xrandr -q output shows one thing extra '1400x1050' :

Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 2048 x 2048
DVI-0 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 380mm
x 300mm
   1280x1024      60.0*+   75.0     60.0     60.0* 
   1400x1050      60.0  <==============  WHY IS IT SHOWN?
   1280x960       60.0  
   1152x864       75.0  
   1024x768       75.1     75.0     70.1     60.0  
   832x624        74.6  
   800x600        72.2     75.0     60.3     56.2  
   640x480        75.0     72.8     72.8     75.0     60.0     59.9  
   720x400        70.1  
VGA-0 disconnected (normal left inverted right x axis y axis)

- Any clue why it is showing the extra "1400x1050"? I couldn't set this

- When reduce the 'Virtual 2048 2048' to 'Virtual 1024 1024' i don't get
'1400x1050' and infact, i get fewer than listed above.

*** The observation is same whether "Monitor" section present or not. And no
'modes' section in my Ubuntu xorg.conf
