LCD monitor resolution

Got a new Samsung 22" 1920x1080 monitor and the default resolution being shown was 1280x800. Now with 8.04 I used to do dpkg-reconfigure xserver-xorg and it would redo the X11 configuration.

In Jaunty, the above command just configures the keyboard setting. In order to get the monitor to work with the correct resolution do

$ xrandr

This would probe the monitor and display the resolutions, then do the following

$ xrandr --output VGA --auto --above LVDS
