Firstly I apologise if this has been asked and answered here before. I
did a quick search but came up with nothing so far so I'm opting for the
"just ask" option ;-).
I have 3 edubuntu dapper servers with ltsp 4.2  and I have a problem
where the students have gotten lazy and Crtl+Alt+Backspace to logout.
Often I'll see quite a lot of zombie processes on the servers and the
like, xdmcp leases seam to increase and the way we load balance is far
less accurate than it used to be. I think, because they have done the
quick trick of Crtl+Alt+Backspace and not logged out using the correct,
preferred method thus leaving some of their processes behind.
Is there any way that I can get a Crtl+Alt+Backspace key event on the
thin clients to log a user out, rather than restarting the Xserver (I'd
still like to be able to restart X though, maybe an extra combination
like Ctrl+Alt+BackSpace+0 if possible).
We also seam to have a problem where lbussd hogs resources and users
sometimes can't access their usb pen drives. I really don't know where
to start to diagnose why, but I have found that using slay to kill that
users processes and removing .lbussd.out and .lbus_fifo from their home
directory seams to do the trick.
I really can't wait till the next LTS release, updated openoffice,
firefox3 and mainly all the cool things the members of Ltsp Drivers and
others are doing to the ltsp side.
