[Bug 587426] Re: No GPU found (Miha Furlan)

[Skip Guenter]

Tried this today on one of my 'dedicated' BOINC crunchers.

else
sleep 9
export DISPLAY=:0.0
xhost local:boinc &> /dev/null
# /home/skip/setfan.sh
start-stop-daemon --start --quiet --background --pidfile $PIDFILE \
--make-pidfile --user $BOINC_USER --chuid $BOINC_USER \
--chdir $BOINC_DIR --exec $BOINC_CLIENT -- $BOINC_OPTS
fi

The ATI GPU WUs are up and running (confirmed from a remote machine) w/o 
me having signed on! Great!

Also tried it, twice, with and w/o the "export DISPLAY" command. Did not 
work w/o the "export DISPLAY" command being present.

As instructed by Miha I created /etc/gdm/custom.conf (When did this 
change from gdm-custom.conf?) as pasted below:

# to allow user "boinc" to connect prior to logon
[xdmcp]
Enable=true

I have a couple machines that were plagued by this so many thanks to Miha.


PS: Anyone feel up to the instructions to block the suggested ports?
