I recently installed kde5 on debian stretch. I have a yubikey which I
use to log in with. I'd like to lock the screen when I remove the
yubikey. I have it working with cinnamon and lxde but I can't quite get
it with kde. I can lock the screen if I run the shell script from a
terminal as root but when I remove the yubikey the shell script returns
error code 1.
Here's my shell scripts:
ykgone.sh
Konsole output
#! /bin/sh
if [ -z "$(lsusb | grep Yubikey)" ] ; then
if [ ! -z "$(ps aux | grep cinnamon-session | grep -v grep)" ] ;
then
/bin/su rjonasz -c "DISPLAY=:0
cinnamon-screensaver-command -l"
elif [ ! -z "$(ps aux | grep startkde | grep -v grep)" ] ; then
/usr/bin/sudo -u rjonasz -H -i /usr/local/bin/lockkde.sh
else
/bin/su rjonasz -c "DISPLAY=:0 xscreensaver-command --lock"
fi
fi
lockkde.sh
Konsole output
#! /bin/sh
kde_pid=`pidof kdeinit5`
export `cat /proc/$kde_pid/environ|grep -ao
'DBUS_SESSION_BUS_ADDRESS=[[:graph:]]*'`
/usr/bin/qdbus org.freedesktop.ScreenSaver /ScreenSaver Lock
I can't seem to figure this one out.
Thanks for any help!
