The output of "xrandr"
yasith@vostro:~$ xrandr
Screen 0: minimum 320 x 200, current 1366 x 768, maximum 8192 x 8192
LVDS1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 293mm x 165mm

VGA1 disconnected (normal left inverted right x axis y axis)
HDMI1 disconnected (normal left inverted right x axis y axis)
DP1 disconnected (normal left inverted right x axis y axis)
Then I ran,
xrandr --newmode "1440x900_60.00" 106.50 1440 1528 1672 1904 900 903 909 934 -hsync +vsync
To create a new mode. Then when I try to set that mode to LVDS1 using the following command I get an error.
yasith@vostro:~$ xrandr --addmode LVDS1 1440x900_60.00
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 150 (RANDR)
Minor opcode of failed request: 18 (RRAddOutputMode)
Serial number of failed request: 29
Current serial number in output stream: 30
Any help on this would be greatly appreciated.
