[ubuntu-uk] no title bars on windows

[Jacob Mansfield]

having recently uninstalled Plymouth (it was becoming annoying) I
reboot only to discover that the title bars of all of my windows have
dissapeared. I can open programs but not close, minimise or resize
them.
could plymouth have affected this and how do I get them back.
