No 1680x1050 for external monitor

[Dotan Cohen]

I just installed Kubuntu 12.04 on a neighbour's laptop computer with
Intel graphics. He uses the computer with an external monitor attached
as the laptop's builtin monitor is faulty and useless. Both the laptop
internal monitor and the external monitor are of the same resolution:
1680x1050.

When configuring the resolutions with the KDE graphical tool, there is
an option for 1680x1050 for the laptop monitor, but for the external
monitor the options only go up to about 1200x768. When connecting this
monitor to my desktop to test (Kubuntu 11.10) the desktop sends it
1680x1050 with no problems. So why won't the Kubuntu 12.04 laptop send
it that resolution? How can I fix this?

Thanks.
