Ubuntu – External monitor Ubuntu 11.04 64 bit not working


just installed Ubuntu 11.04, but cannot get my external monitor to work in "same image in all monitors" mode.

Its only possible to choose same resolution for the external monitor as for the laptop.

External is 1920*1080, laptop 1200*800px

When mirror is selected, ubuntu identifies BOTH monitors as "laptop" and BOTH monitored displays 1200*800px.

Any help much appreciated …

Best Answer

Do you have a Nvidia graphic-card? There is a special tool for Nvidia called disper. It should work with other cards too.

You can install disper from ppa:disper-dev/ppa

Then type

disper -c

This should clone the desktops on internal an external monitor. See here on launchpad.
