I have installed Ubuntu 14.04 on my Thinkpad T60 and found out that Unity is too slow. So, I did
sudo apt-get install xubuntu-desktop
When I log into an Xubuntu session, the panel has a ton of junk from the Unity interface (a Power menu with a non-working logout button, an extra language indicator that does not work, an extra clock).
How can I get rid of them, ideally without breaking my ability to log into Unity?
EDIT: I found other questions that ask about the same problems. They do not seem to have any useful answers:
