Cannot make external HDMI monitor the default monitor

[Zach Pfeffer]

Binary package hint: gnome-control-center

I have a System76 Lemur Ultra Thin laptop with an external HDMI monitor connection. I'm able to plug in my HP Compaq LA2405wg monitor via a DVI to HDMI converter and, using gnome-display-properties.

I upgraded to 11.04 from 10.04.

I used to be able to turn off the Laptop screen and the HP screen would become the default. When I do that now both screens go blank (I have the power manager set to blank the screen when the lids closed but the system is on AC power.

When I click on the HP screen in the GUI and click Make Default I get a pop up that says:

Authentication is required to install multi-monitor settings for all users. etc...

The details say:
polkit.subject-pid: 1804
polkit.caller-pid: 2396
Action: org.gnome.randr.install-system-wide
Vendor: GNOME Monitor Preferences

I authenticate and it says that those will be the defaults when the next user logs in.

I log out and log back in and the laptop screen is still the default.

Running sudo gnome-display-properties didn't solve the problem, it just skipped the authentication stage.
