I have worked on getting the X display to lock automatically when I
use APM on my laptop. I used the standard scripts provided by the
package apm-scripts.
I run KDE and the locking is thus governed by the following part of
the shell-script:
w |tail +3 |awk '{print $1, $3}'|grep -v '-'|grep : | \
sort -u | \
while read line; do
Usern=`echo $line |awk '{print $1}'`
XDisp=`echo $line |awk '{print $2}'`
if [ "x`/sbin/pidof 'kdeinit: kdesktop'`" != "x" ]; then
# We're running KDE - a dcop call is sufficient.
su $Usern -c "DISPLAY=$XDisp dcop kdesktop KScreensaverIface 'lock()'"
else
When trying to run the script I encountered two problems:
- the listing from w do not include my DISPLAY, cf the following
example output
1:25am up 7:40, 4 users, load average: 0.58, 0.61, 0.61
USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT
turtle pts/1 - 12:59am 26:11 0.00s 0.00s /bin/cat
so the line was removed by grep -v '-' in the pipe.
I solved this problem by using:
who |awk '{print $1, $2}'|grep -v '-'|grep : | \
instead.
- the call to su produced an error that DISPLAY could not be found as
a command. I solved that changing the line to:
su $Usern -c "env DISPLAY=$XDisp dcop kdesktop KScreensaverIface 'lock() '" &
So now the scripts are working for me, but I wonder if I am the only
one who have experienced these problems.
