Dual Head monitors is not very good supported till the version 8.10 of Ubuntu. All versions after Ubuntu 8.04 (starts at 8.10) will support Dual Head graphiccards.

I tested it now on a Nvidia Quadro Fx370 2xDVI. It works only with the default driver of Ubuntu.

If you run in the same issue as me and the whole second screen is not useable, just do an reboot of the machine and change the resolution lower and then back to higher again ;-)

Sometimes, when you try to login in a Windows VM, it's not possible to unlock the login screen with CTRL+ALT+DEL, because the remote console will put you out of the VM window.

Don't be worry if it is so, just use instead of the DEL key the Num_DEL key. Then it will work!

If you will try to run Thunderbird 2.0.0.19 and Lightning 0.9 and you the calendar won't work, so don't be angry! Just install a library and restart Thunderbird.
You will see, it will work ;-)!

sudo apt-get install libstdc++5
