Comment 132 for bug 541492

Interesting link and read as provided by Aether (comment #131).
Unfortunately Ubuntu does no longer use inittab and I know to little on how to control the startup order.

I know it is controlled by the S and the number following it in the /etc/rcX.d (where X represents the runlevel) that is preceeding the file names. However, it seems to me that the X environment is started from /etc/rcS.d directory and I can not really see when that kicks in. If this is at the end of the boot process my understanding is that X is already started as last.

Can someone please confirm and test this (or explain how I can test it) since until now none of the suggested workarounds have provided a stable environment for me.
