Our site runs a net of Suns (mainly 3/50's) and I like to use both
SunView and X at different times. The Problem is that while SunView
can be killed with no problem, X doesnt seem to have a shut-down
option, and when the relevant processes are killed, it tends to do
*strange* things to the workstation. Does any know of any graceful
way of terminating X without re-booting?

It confused me for a while, too. Check out the source directory for the Sun server - there is a little program called "kbd_mode". You just need to make sure that a "kbd_mode -a" gets executed after the server exits. If the server exits gracefully, it's redundant, but when it crashes... Make a script that is basically: #! /bin/sh xinit kbd_mode -a Use that to start X. Should do it, if that *IS* the problem you're having. Brian brsmith@umn-cs.cs.umn.edu

I alias my xinit to "xinit .xstartup ; kbd_mode -a". kbd_mode was described in previous follow-up. Makes sure keyboard isn't left in weird state. .xstartup is my shell script to start up various windows. 2). My shell script ".xstartup" is structured thus: #!/bin/sh ( xterm & xterm & .. exec xterm -C -n "CONSOLE" ) 2>/dev/null 1>/dev/null The stdout & stderr are piped to /dev/null so that when Xsun dies (my 3rd point) no needless error messages are seen. (No doubt, sh/unix wizards can find a better way to do this..) NOTE: You should make sure everything in the shell script works correctly before you discard the output or you will never know why a particular X application didn't start. One disadvantage is that you won't get any error messages from window manager spawned processes that would normally show up in your xterm -C shell. 3). When I want to exit X I explicitly send a "kill -INT" to the `Xsun' process number. I have a shell script called `killbyname' which kills processes by name (by `awk'ing the ps output), so: "killbyname -INT Xsun". 98 times out of 100 (more or less) when I exit X it works correctly: X applications quietly terminate and, shortly, I get my prompt back ready for SunView or X. Once in a while something goes wrong and weird things happen (as you described) but not often. Disclaimer: Sure its a kludge, but at least it exits as nicely as SunView. -- Tedd Hadley (hadley@ics.uci.edu)

The clients are set up with the default of no window system at log-in, and the user executes xinit or suntools to bring up the window system of choice. X seems to exit just fine (by exiting out of the console window) and I can switch between the two systems without any problems. I'm sure we have the plain-vanilla MIT distribution.

We have a script which causes AWM to be run as the primary client. AWM can be told to run other clients, such as xterms. The problem then degenerates to one of killing AWM. This is easy, since AWM provides it as a standard feature, just configure a popup menu option that calls the exit function. Then, hit the EXIT option, and Hey Presto, X exits. Of course, you still need to clean up the keyboard. Since our server can run on top of and with Sunview, this is a little more complicated than normal, but still fairly straightforward. I hope this helps. regards, Richard. P.S. Our server is available now on all Suns, with all sorts of optimisations, bug fixes and other goodies.
