I installed server 12.10 with the "--without-recommends ubuntu-desktop" option - this gives a minimal Unity GUI, without most of the addons for a desktop user.

But now I cannot figure out how to reboot. There is no system menu with these options; calling reboot from terminal prompt requires access to root.

Still very new to Ubuntu. How do I reboot from the GUI? control-atl-delete logs out, but does not reboot.

Don't know if you can do it from the GUI, but from the Terminal, sudo shutdown -r now will do the trick.

If you want to power the machine off, sudo shutdown -hP now - the h is for halt, and the P is for Power off.

Opened terminal in Unity - typed it in - prompted for password and did reboot. Tnx. – Vector Nov 25 '12 at 22:12
BTW - how do you turn the machine OFF? – Vector Nov 25 '12 at 23:16

When it prompts you for the root password, type your own password. As the person who installed it, you should automatically be in the sudo group.

I reboot with

sudo shutdown -r now

sudo shutdown -h now – GaryBishop Nov 26 '12 at 0:49
correction: sudo shutdown -hP now - the P (yes, capitalized) tells the machine to actually turn the power off. If you omit it, it halts but does not power off, which I have never really known ANYBODY, including myself, to want. :) – Jim Salter Nov 26 '12 at 1:15
