Scratch #11, wasn't running as root, which of course the powerbtn.sh
would be :-)
Cut'n'paste tests now show
... as before ...

Ahh ha ! That is the line that's meant to spot KDE4 and poke it... it
looks like a horrible undocument mess to me though.
r...@wopr:~# pidof kded4

r...@wopr:~# ps -efww|grep kded4

I found the process I think it should be asking for, and it looks like it
should work:
r...@wopr:~# cat /proc/1955/environ |tr '\0' '\n'|grep DB
DBUS_SESSION_BUS_ADDRESS=unix:abstract=/tmp/dbus-wZqbwHsRWt,guid=a017520a52ed70c025d498814bdc07f1
r...@wopr:~# su - $XUSER -c "eval export
DBUS_SESSION_BUS_ADDRESS=unix:abstract=/tmp/dbus-wZqbwHsRWt,guid=a017520a52ed70c025d498814bdc07f1;
qdbus org.kde.kded"|grep powerdevil
/modules/powerdevil
r...@wopr:~#
As a suggestion, the final test should replace 'pidof kded4' with 'ps
-efww|grep kded4|grep $XUSER|grep -v grep|grep -v defunct
' or similar.
I do not believe the defunct is the problem, rather there are many kded4's (one
for me, one for root, one for every user logged in ?). I've filtered out
defunct ones anyway, and also restricted it to the current X user name. This
should more reliably locate the one KDE instance we are interested in.
This appears to work:
PIDOFKDE4=`ps -efww|grep kded4|grep $XUSER|grep -v grep|grep -v defunct|tr -s '
'|awk '{print $2}'`
if pidof x $PMS > /dev/null ||
( test "$XUSER" != "" && pidof dcopserver > /dev/null && test -x
/usr/bin/dcop && /usr/bin/dcop --user $XUSER kded kded loadedModules | grep -q
klaptopdaemon) ||
( test "$XUSER" != "" && test -x /usr/bin/qdbus && test -r
/proc/$PIDOFKDE4/environ && su - $XUSER -c "eval $(echo -n 'export '; cat
/proc/$PIDOFKDE4/environ |tr '\0' '\n'|grep DBUS_SESSION_BUS_ADDRESS); qdbus
org.kde.kded" | grep -q powerdevil) ; then
echo hello
fi
Attached is a a version of powerbtn.sh that works for me.
Someone with more Bash voodoo might want to take a look at this.
Using this version, with a power button press, hibernate and resume betwen the
two ls's :
r...@wopr:~# ls -lah /tmp/powerbutton.fail
-rw-r--r-- 1 root root 0 2010-05-03 22:01 /tmp/powerbutton.fail
r...@wopr:~# date
Tue May 4 23:10:10 BST 2010
r...@wopr:~# ls -lah /tmp/powerbutton.fail
-rw-r--r-- 1 root root 0 2010-05-03 22:01 /tmp/powerbutton.fail
r...@wopr:~# date
Tue May 4 23:12:20 BST 2010
this indicates the script correctly bailed rather than falling through
to the shutdown.
