[gentoo-user] How to stop X

[Kevin O'Gorman]

I'm having trouble configuring X, and to save time I'd like to be able
to shut it down, edit some stuff, and start it up again.

What is the gentoo way to do that?

Gentoo or not, make your changes to /etc/X11/xorg.conf, logout from your X 
session, change to a virtual console and restart the display manager 
(/etc/init.d/xdm restart), which also restarts X as a side effect.

It is simpler to use ALT+CTL+BKSPACE to restart the display manager

There's this thing that RedHat gave us called DontZap that gets in the way of 
that

It depends on how you started X in the first place. If you did a
"startx" (or similar), logging out should be all you need to do to get
out of X. If you use a login manager, XDM/GDM/KDM then it'll restart
itself so you'll need to switch to a VT (ctrl-alt-F1) and then sudo
/etc/init.d/xdm stop to shut down XDM (and therefore X). You can then
rmmod your video drivers or do whatever changes you want to do. sudo
/etc/init.d/xdm start to bring it back up.

Several of you suggested "/etc/init.d/xdm start" or so to get it
(re)started.  It doesn't work.  Instead the start-stop daemon
complains of not being able to stat "/usr/bin/xdm" which doesn't
exist.  And no I didn't mispell it.  I've never seen this before an
I'm baffled.

Hi,

You haven't told us how you start X, which I think would make it
easier to determine how to stop it. Maybe you don't use XDM at all, in
which case the above suggestion wouldn't have any relevance to your
situation.

I haven't told you because I don't know.  I do know that I was using
KDE when I still had X.  But I set that up over 5 years ago and I've
forgotten all the details.  But there's no sign of *dm in /etc/init.d,
other than xdm, which acts pretty normal outside of the fact that it
fails.  It goes through motions, says some things work by putting [OK]
in the right margin, and all that.

If you tell me how to find out, I'll answer any questions.

Except that it doesn't work at all when your X is as hosed as mine.

But it applies to Gentoo as well.  From my xorg.conf.example on Gentoo.

# Uncomment this to disable the <Crtl><Alt><BS> server abort sequence
# This allows clients to receive this key event.

#    Option    "DontZap"

It's a valid option on every Linux I have ever played with.

Look at your ps axf.  If it is running via xdm you will see something like:

6403 ?        Ss     0:00 /usr/bin/xdm 
6417 tty7     Ss+   28:54  \_ /usr/bin/X :0 -nolisten tcp -br

There are the 'big three' display managers, xdm, gdm(gnome), and kdm(kde)
which all do the same job, i.e. asking for your user name and password.

All three of them are X applications and therefore they start the X
server before they can appear on your screen.

Before your troubles started, what did you see when your machine boots
up.  Does it ask your username on an ordinary black-and-white console,
like a teletype, or on a fancy graphics screen with sexy eye-candy so
as to seduce unsuspecting MacBook users?

Right, but the latest flavor of xorg works without the requirement for a 
xorg.conf and therefore there's nowhere to define <Crtl><Alt><BS> in the .fdi 
files from what I recall.  Retaining a xorg.conf would be the alternative - 
thus keeping the old Gentoo (and every other Linux) way.

True, but how many people have actually did the upgrade?  I haven't yet. 

Also, you can have a xorg.conf still to specify the option.  That may be
the only thing in the file but it would still work.

Hi Kevin,

This weekend I needed to stop and start X a lot because I was
experimenting with running dosemu from a tty command line and the
DOS application I'm running under dosemu hangs the command line.

Using an ssh session (from another machine) I found that
"/etc/init.d/xdm stop" works to stop X. However,
restarting is a bit tricky since "/etc/init.d/xdm start" fails because
of files in "/var/lib/init.d/*/xdm".  If one runs "rm -rf /var/lib/init.d/*/xdm"
then runs "/etc/init.d/xdm start" one is good to go.

HTH,

David

What I get is not much, but it appears I'm still running kdm and it's
a child of init.

Then /etc/init.d/xdm zap may be easier and cleaner.

/etc/init.d/xdm runs either xdm, gdm or kdm, depending on the setting
in /etc/conf.d/xdm. I suspect you may have inadvertently overwritten this
with etc-update or similar after an update, setting it back to the
default of xdm.

I hadn't known of zap.  Indeed it's an easier way to do the cleanup.
However, use it _after_ stop.  

I tried it instead of stop.  What it does is remove the 
/var/init.d/*/xdm files.  With them gone,  "/etc/init.d/xdm status"
can't tell that xdm has been started and "/etc/init.d/xdm stop" doesn't
do anything.  I had to frog around to fix the problem.

Be careful !!

True, you do have to use it after stop.  It is supposed to reset
everything to a stopped state.  I think it also kills running processes
but I have not tested that to see if it does for sure.  I just know that
it works and does so cleanly.  It's certainly a better option than
trying to do it manually.
