Binary package hint: gnome-control-center
Following instructions for testing external monitor on a laptop in http://testcases.qa.ubuntu.com/Hardware/GFX/ExternalPrimary
the resolutions of the external monitor are not detected properly. When I try to change them, also the Laptop Screen flickers and changes sizes (with "same image" option disabled, of course).
Worse is when I try to set the external monitor to be primary (by turning off the laptop screen), both screens turn off.
# Plugged external monitor
# Go to Monitor in the Unity launcher.
# Both screens are detected.
# Tried different resolutions and more or less some of them worked (there where some resolutions external monitor isn't capable of).
# Selected Laptop monitor and switched off, click apply.
# Both monitors turned off and had to wait for the 30 second dialog to restore the last configuration. I was hoping the laptop screen to turn off and the external monitor be the primary.
Then tried the switch screen har-button in this laptop (Fn + F8) but it triggers a "super" key instead (like the win logo).
Afterwards Compiz crashed (Bug #766496).
