Ubuntu Problem with LG Flatron L222WS

Picked this one up a while ago, but thought I might just make a note of it now.

It also seems to have been logged as bug for Ubuntu: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/212018

This is what I did to resolve:

1st I need an xorg.cof file:

sudo service gdm stop
sudo Xorg -configure


Then we edit it and add the lines in bold:

Section "Monitor"
    #DisplaySize      470   300    # mm
    Identifier   "Monitor0"
    VendorName   "GSM"
    ModelName    "L222W"
    HorizSync    28.0 - 83.0
    VertRefresh  56.0 - 75.0
    Option        "DPMS"
    Modeline "1680x1050 at 60.0" 146.25 1680 1784 1960 2240 1050 1053 1059 1089 +hsync -vsync
    Option "PreferredMode" "1680x1050 at 60.0"
EndSection

Then start X again

sudo service gdm start


Update: 16/1/2011

This did work for my old Video card, now I've upgraded to ATI HD 5770 it did not seem to do the trick.

This line did however work:

Virtual    1680    1050
Modes        "1680x1050@60"    "1600x1024@60"    "1440x900@60"    "1280x800@60"    "1280x720@60"    "1280x768@60"    "800x600@60"    "800x600@56"
