I'd like to set up my Ubuntu 12.04 laptop so that I can play a video on loop while my computer is unattended, while not allowing anyone to take over without a password. I think this could go one of two ways, but both seem unneccesarily difficult or hacky:
-
Find a video player that can lock the keyboard and mouse with a password, or
-
Use the normal ubuntu lockdown with a screensaver that plays a video on loop.
Unfortunately, I'm having trouble finding an easy way to do (1) and it looks like Ubuntu doesn't even have screensavers any more, so (2) is difficult as well.
Any suggestions about the best way to do this would be helpful.
