The Ubuntu people made a change to the X windows interface for
the 9.04 (Jaunty Jackalope) release. It doesn’t matter very much
to me, but it does (by default) remove a feature that I use once
in a while. Formerly, if you wanted to kill your X windows session
without rebooting the machine, you could say
<CTL><ALT><backspace>, and now by default that
sequence doesn’t do anything.
I’m not sure I agree with this decision — the rationale is
apparently that people sometimes hit that sequence by accident,
which doesn’t seem to ever happen to me.
In any case, if you want the feature, putting it back is pretty
easy. There are places that will tell you what to put in your
/etc/X11/xorg.conf file, but the easy way is to install the
“dontzap” package, and then run
Lilies of the valley
When I posted the last set of garden pictures, I forgot to
include the lillies of the valley.
