Hi,
I have a setup here where an xscreensaver hack can be loaded on-demand,
and cycle or throttle when pressing another button. Unfortunately, the
hack is loaded only when vieving TV or a film.
I'm under X, with the ratpoison WM.
xscreensaver is loaded in the .xsession.
/etc/freevo/irexec.conf looks like
begin
remote = streamzap
button = Power
prog = irexec
repeat = 0
config = /etc/freevo/tvsound_switch
end
begin
remote = streamzap
button = Red
prog = irexec
repeat = 0
config = /etc/freevo/screensaver_switch
end
begin
remote = streamzap
button = Green
prog = irexec
repeat = 0
config = xscreensaver-command -cycle
end
begin
remote = streamzap
button = Yellow
prog = irexec
repeat = 0
config = xscreensaver-command -throttle
end
and /etc/freevo/screensaver_switch is
#!/bin/sh
if [ ! -e /var/run/screensaver.pid ]
then
xscreensaver-command -activate
pid=`pidof xscreensaver`
#
echo "$pid" > /var/run/screensaver.pid
else
xscreensaver-command -deactivate
rm /var/run/screensaver.pid
fi
When I try to run /etc/freevo/screensaver_switch when Freevo has the
control (i.e whan not having a tvtime or mplayer window on the
screen), I get the following error message
xscreensaver: 23:19:16: ACTIVATE ClientMessage received.

The ususal googling leaves me in a desert.
Now the question : would it be possible for freevo not to grab mouse or
keyboard for IR-only interaction setups? Do one know where should I
start? Thanks,
Marco
P.S : I feel that this on-demand activation of the screensaver is in
fact easier to handle for both the user and the programmer : ) You can
choose -or not- to activate it at a given moment of the session, then
you can forget it. And the Mute/xscreensaver -throttle combo could put
freevo in a kinda "soft sleep" mode. For now I'll keep tvtime in the
background, it's not a big deal, many thanks to the developpers for all
the work done, freevo is a *very* nice piece of work.
