Start and stop script with screensaver
 
Hello I would like to start and stop rtorrent based on my screensaver. I used to do this awhile ago with ubuntu and still have my script which may be helpful to someone else.

However now I am using Fedora with KDE and the script no longer seems to work. Could someone please help me with either another solutions or assist me in getting this to work:

#!/usr/bin/perl
#gnome
my $cmd = "dbus-monitor --session \"type='signal',interface='org.gnome.ScreenSaver',member='SessionIdleChanged'\"";

open (IN, "$cmd |");

while (<IN>) {
if (m/^\s+boolean true/) {
#when screensaver activates, run the following commands
#system("/home/eric/compiled/scripts/rtorrentstart");
system("touch /home/asoukenka/rtorrenthasstarted");
} elsif (m/^\s+boolean false/) {
#when screensaver deactivates, run the following commands
#system("kill `pgrep rtorrent`");
system("touch /home/asoukenka/rtorrenthasbeenkilled");
}
}


just found my old post where some people helped me with this

For starters, the interface name needs to be changed since you are no longer using GNOME. Something like "org.kde.Screensaver"
Quote:

my $cmd = "dbus-monitor --session \"type='signal',interface='org.gnome.ScreenSaver',member='SessionIdleChanged'\"";
Use qdbus or qdbusviewer to figure out the exact object and method names.

Thank you require further assistance though
 
Nevermind all is fixed now. For those who want it here is the final script.

#!/usr/bin/perl
#requires:
# rtorrent, screen, gnome/kde, perl
#
# Instructions:
# - Properly comment the line for gnome or kde
# - Give script execute permission (chmod +x)
# - Run script ./<scriptname> **** do not use rtorrent in script name will mess up kill command
#
# There is a log file created by the script at /tmp/autortorrent
#
#


#gnome
#my $cmd = "dbus-monitor --session \"type='signal',interface='org.gnome.ScreenSaver',member='SessionIdleChanged'\"";

#kde
my $cmd = "dbus-monitor --session \"type='signal',interface='org.freedesktop.ScreenSaver',member='ActiveChanged'\"";
open (IN, "$cmd |");

while (<IN>) {
if (m/^\s+boolean true/) {
#when screensaver activates, run the following commands
system("echo \"--------------------------------------------------------------------\" >> /tmp/autortorrent");
system("screen -dmS rtorrent rtorrent");
system("echo \"started:\" >> /tmp/autortorrent");
system("date >> /tmp/autortorrent");
system("echo \"--------------------------------------------------------------------\" >> /tmp/autortorrent");
} elsif (m/^\s+boolean false/) {
#when screensaver deactivates, run the following commands
system("echo \"--------------------------------------------------------------------\" >> /tmp/autortorrent");
system("kill `pgrep rtorrent`");
system("echo \"stopped:\" >> /tmp/autortorrent");
system("date >> /tmp/autortorrent");
#system("ps aux |grep rtorrent >> /tmp/autortorrent");
system("echo \"--------------------------------------------------------------------\" >> /tmp/autortorrent");
}
}

Hello,

I slightly modified your code to have Kopete disconnected on screen saver start and reconnect when screen saver unlock...



Code:

#!/usr/bin/perl


#gnome
#my $cmd = "dbus-monitor --session \"type='signal',interface='org.gnome.ScreenSaver',member='SessionIdleChanged'\"";

#kde
my $cmd = "dbus-monitor --session \"type='signal',interface='org.freedesktop.ScreenSaver',member='ActiveChanged'\"";
#my $cmd = "dbus-monitor --session \"type='signal'\"";
print "---$cmd----\n";
#exit;


open (IN, "$cmd |");

while (<IN>) {
  if (m/^\s+boolean true/) {
    #when screensaver activates, run the following commands
    system("dbus-send --type=method_call --dest=org.kde.kopete /Kopete org.kde.Kopete.disconnectAll");
    print "Kopete disconnected\n";
  } elsif (m/^\s+boolean false/) {
    #when screensaver deactivates, run the following commands
    system("dbus-send --type=method_call --dest=org.kde.kopete /Kopete org.kde.Kopete.connectAll");
    print "Kopete connected\n";
  }
}
