F12 upgrade on lenova - desktop issues.

[William Henry]

Hi,

I upgraded to F12 using the preupgrade over the internet option. I had done this with F11 with great success. 

Now that I can see the working desktop it is looking pretty much the same as my F11 setup.

However I have a problem when I reboot in my docking station with the external monitor and the laptop screen closed. F12 seems to continue to default to using the monitor as an extension rather than a mirror. Therefore in my docking station - neatly tucked in under my desk - I can't do any work. I've tried to undock and mess with the Desktop settings and force it to mirror (and apply and close) and then reinstall in my docking station and restarting. Still uses my monitor as an extension and my laptop is rendered useless. So I'm typing this with the laptop off my docking station.

Anyone have any ideas?

William
