I can describe what happened here... Ubuntu 10.04, two years ago. Server
has nvidia card in it. Clients have intel video chipsets. Install ltsp and
get it working. Install proprietary nvidia drivers on the server (through
the ubuntu gui for drivers) --> all text upside down on clients. Two
solutions: Remove nvidia drivers on server, problem solved. Or... switch to
metacity (from compiz) on the clients and problem solved. I have notes to
achieve that if anyone needs them.
