Dear friends,

on the recommendation of Waltraud Niepraschk you have to take the 
following steps for solving the problems if they happen on a screen
in the control room of PITZ:

1. a screen is frozen
======================

  you can restart the Xserver on this machine.
  Change to root with su (you need a password)
  Look for the X server process:

[bubo] / # pp /usr/openwin/bin/X
     UID   PID  PPID  C    STIME TTY      TIME CMD
doocsadm 10133 10132  1 08:17:13 console  1:50 /usr/openwin/bin/X :0 -dev /dev/fb0 -dev /dev/fb1 top -nobanner

  kill the process with
     kill <PID>

---- AND THEN:
  on bubo: now you get a shell
           logout and you should get automatically a new X11 environment
---- OR:
  on aquila, corvus and other Suns with graphical console:
  send a 'HUP' signal to the primary xdm process.
  with
     kill -HUP `cat /usr/sue/lib/xdm/xdm-pid`
-----------------------------------------------

2. someone has locked the screen with xlock
==========================================

  Change to root with su (you need a password)

  Look for the process xlock
  pp xlock

  kill the process with
     kill <PID>

Please don't hesitate to send me an email, or phone me, if there are any errors, remarks or requests.

Best regards, Bert.
