I usually start Xorg from the command line and log out to the command
line when done. One thing I've noticed is a nasty message from
xscreensaver about how we've installed it incorrectly or that we are
running as root (suid) when we shouldn't be.
I've traced that down to a function that tries to restart xscreensaver
when it gets a SIGHUP signal. It is getting this either from the window
manager (in my case xfce) or the kernel. But of course the restart
fails because Xorg has shut down the display.
I have fixed this in my build script with the following:
sed -i -e '/restart_process/i\ exit(0);' \
-e '/restart_process/,+1d' \
driver/windows.c
I don't think this is suitable for the book, but am putting it out here
so that searches may find it.
The sed is actually interesting as it inserts a line and then deletes a
range (two lines) at the same point. It requires gnu sed as it uses an
extension the to the posix standard.
