Shutdown Ubuntu 10.04 from second monitor (docked T410)

[hart22]

I'm dual booting Windows 7 Pro and Ubuntu 10.04 on my T410. Everything works fine except I have one minor problem. I use a dock at home connected to a larger monitor. In Windows 7, I plug in the laptop (display cover closed, power options set to blank screen w/ lid closed on AC) and I can easily login / shutdown from my second monitor. However, in Ubuntu both the login screen and shutdown screen always appear on my T410 laptop screen, even when it is closed and I am using my second monitor alone. So I have to open the laptop and login / shutdown from there. Has anyone run into this problem? I've tried searching on Linux / Ubuntu forums but haven't had much success. A fix is greatly appreciated.

In the T410's BIOS make the external LCD the default primary video device. The device option will be something like 'Digital 1 on Dock'.

Many thanks for the quick reply. Unfortunately setting the external LCD as the default display (tried both "Digital 1 on Dock" and "Digital 2 on Dock") did not solve the problem. When I reach the Ubuntu login screen the window for user selection and login credentials still remains on the laptop LCD. Similar for shutdown dialogs. I did try searching Linux forums for instructions on setting default displays but still haven't found much yet. I'll keep searching...

Maybe use xrandr? Something like

Code: Select all

   
xrandr --output LVDS1 --off --output VGA1 --auto &

in your Xsession should do the trick.

stgreek I see you list having a T600e and are running Ubuntu 10.04 -- Did you find a Ubuntu 10.04 sound fix (and external microphone) solution for the 600e?
