Hi Andy, so far normal behavior.
When I am physically on that machine, doing the same command results
in the
montitor shutting off.
I tried ssh -X, and ssh -x, tried DISPLAY=:0.0 xset but none of it
works.
You dont want to forward to your local X session. Dont do that ;)
Anyone has a clue?
set up your environment
# export DISPLAY=:0
- If your X server is up,
- and no one is logged in.
Which display mananger is running (gdm, xdm ,kdm) ?
You need access to the X session cookie.
Keyword: MIT-MAGIC-COOKIE-1, XDM-AUTHORIZATION-1
Read man Xsecurity and man xauth
It should be in your .Xauthority file ...
Coping as root is enough.
something like
# cp /etc/X11/xdm/......MIT-MAGIC-COOKIE-1 $HOME/.Xauthority
Its to long ago to be exact. Just look into man pages.
Good luck.
Moire
