On my laptop I’m running Ubuntu Linux 8.04 with
XFCE 4.6 and it works great. But (Isn’t there
always a but'?) every once in a while I killed my Xsession with some
type of key combination. The standard combination for this is
`Ctrl-Alt-Backspace so I switched that off in the file
/etc/X11/xorg.conf'. I added the`ServerFlags`section, like this. ~ Section "ServerFlags" Option "DontZap" "on" EndSection ~ After restarting I tried the dreadful`Ctrl-Alt-Backspace
and I thought that `Bob’s your uncle'.
How disappointed I would be. I started work again and suddenly my X
session was killed again, and again and again. And then I saw it, I was
not pushing the Ctrl-Alt-Backspace combo, but I tried to insert text
with Shift-Insert and accidentally hit Shift-Backspace. Now I had a
point to start my search.
Googling and file digging revealed that my keyboard was set to PC-101 and that it should be PC-105. Strange, but solvable. I switched the keyboard in the XFCE settings panel and my problem was solved. It can also be solved by adding
setxkbmap -model pc105 -layout us -variant basic
to the startup script for your window manager.
But, of course, I could not just accept the solution and leave it to
that. The problem turned out to be
Compiz, the fantastic OpenGL
accelerated desktop. This has a feature that the Shift-Backspace
turns out to be for debugging purposes.
Yeah, right! We already had Ctrl-Alt-Backspace for that, right!
