[gdm-list] Elevated niceness

["David A. Cobb" <superbiskit cox net>]

 My Hardware: Athlon-XP, 256Meg RAM.
My Software:   Ubuntu 9.10; GNOME 2.28.1.

If I remember correctly, when I installed Ubuntu from scratch, I was 
offered to run the X server at an elevated priority.  I did so then, but 
whatever the installer did got undone in some subsequent upgrade.

I am experiencing a lot of problems with the GUI becoming unresponsive 
under seemingly "normal" loads.  Superficially, it seems there is so 
much stuff running in the background that memory is very scarce for the 
desktop applications.
SO, running some things with an elevated NICE seems a worthwhile idea.
From my account, I can do it with GKSUDO; but that doesn't help my 
other users.  For them, the operation has to be automatic and invisible.

The current targets are:
    Xorg at nice= -18
    gnome-panel=  -6 ; this is inherited by desktop applications 
launched from the panel.
    gnome-session=-8 ; for when I have to manually intervene to kill 
problem applications.

Of course, I'll listen to any suggested improvements in that scheme.
However, my question today is -- where in the gdm session initiation 
sequence can I insert the required commands.  The best way, I suppose, 
is when gdm is running as "root" and launching components.  Failing 
that, a script that will find the applications running and can "renice" 
them.  I've tried some changes in "/etc/gdm/xxx/default" but they don't 
appear to take effect.
