Hello List,
I have written a small daemon, which can replace acpid on VDR systems and was written with dedicated VDR systems in mind.
Core Features: - Faster than acpid with all the required external scripts. - Emergency reboot feature. You don't loose the power button as safe emergency exit button. Just press it four times within three seconds and a clean reboot is triggered. - Very easy to set up. If you want, you can just copy the "vdrpbd" file to your VDR system and execute it. VDR should react to the power button immediately! - Systemd integration. If systemd is detected, then vdrpbd tries to register itself as "power button inhibitor". The module "Net::DBus" is required for this to work.
Note that it requires an up-to-date kernel, as the only supported way, to access the power button, is the input layer. There is no "netlink" support and I also won't add it.

Very cool! Gonna try it. Integration with systemd is very useful. Best, Yarema On Mar 27, 2013 6:45 PM, "Manuel Reimer" manuel.reimer@gmx.de wrote:

Would be very useful, but at least the inhibitor thing, which was intented to block systemd from shutting down the system if the button is pressed, seems to be broken. So if you use it on systemd-based systems, you have to edit /etc/systemd/logind.conf to make systemd ignore the power button.
But as the official console utility "systemd-inhibit" is broken, too, it doesn't seem to be my code but a bug in systemd itself. I reported this to the mailing list and I hope someone can tell me what's going on here.

OK, thanks, it's good to know such a thing before installing on Archlinux. Did you mean set "PowerKeyIgnoreInhibited" to "yes" in /etc/systemd/logind.conf ? BTW, could you post a link to your bug report on systemd?

What about using this with non-systemd init, does it just work by actually deactivating or rather replacing acpid? If that's the case, I could give it a try, but have few more questions:
- I just had a quick look in the git repository, could not find a config file sample, how should that look like?
- Could the command trigger pattern (the 4 presses on the power button within a certain time) also be configurable in that config file?
- Is it feasible to extend the functionality to one or two more patterns to be able to issue different shutdown commands (like a custom hibernation script for example)?

Just execute the binary. It will work without any configuration.
The default behaviour is to fork to background (classic "Unix daemon").
If you want to run the daemon in foreground, then call it with the "-f" parameter.
- I just had a quick look in the git repository, could not find a config
file sample, how should that look like?
So far, officially no config file is needed at all, but on vdr-portal.de my experimental dbus2vdr support has been tested and seems to work, so if you want to use it, create a config file like this:
# echo USE_DBUS=1 > /etc/vdrpbd.conf
- Could the command trigger pattern (the 4 presses on the power button
within a certain time) also be configurable in that config file?
I would prefer to not make it configurable, but this is a 0.x version, so if someone would prefer some other "emergency code" (more keypresses, shorter/longer time), then let's discuss about this.
My hope is, that if more than one distribution adopts this daemon, we'll have *one* standard way to emergency reboot a VDR system.
- Is it feasible to extend the functionality to one or two more patterns
to be able to issue different shutdown commands (like a custom hibernation script for example)?
I think this should be done in the "shutdown.sh" or some similar script, that gets called by VDR as soon as the short timeout, where you can still stop shutdown, is over.

$ echo HandlePowerKey=ignore >> /etc/systemd/logind.conf

Let's seem if this is a bug or a feature. If it is a feature (seems to depend on the session where inhibitor has been created and power key has been pressed) then I can try to find a workaround. If I can't find a workaround, then I'll drop this inhibitor stuff and add documentation on how to disable the systemd default handling in logind.conf.

Hello,
I don't want to hijack your thread, but just as a reference here is my solution with acpid to achieve nearly the same:
/etc/acpid/power:
event=button/power* action=/sbin/acpishutdown.sh
/sbin/acpishutdown.sh:
#!/bin/sh if [ -e /tmp/acpibutton ]; then if [ `/bin/ls /tmp/acpibutton -lc --time-style="+%s"|/bin/cut --delemiter=" " --fields 6` -gt `/bin/date --date="20 seconds ago" +%s` ]; then /sbin/shutdown -h now else /bin/touch /tmp/acpibutton /bin/svdrpsend HITK Power fi else /bin/touch /tmp/acpibutton /bin/svdrpsend HITK Power fi
If you press the power button VDR is told via SVDRP to shut down. If you press the power button two times within 20 seconds, the computer is shutdown directly with /sbin/shutdown.
Best regards Sebastian
