Mageia forum

I need a lirc guru if there is one around.

This remote used to work out of the box with XBMC, and with a little tweaking it worked in MythTV. As of Mageia 2 that all changed. Here are some important details:

I am seeing /dev/lirc0 and have softlinked that to /dev/lirc.

/home/madams/.mythtv/lircrc (http://pastebin.com/kRzHkLzE)

/etc/lirc/lirc (http://pastebin.com/WCcSZPbQ)

Firing up "mode2" as root on the mythbox shows button presses. Running "irw" shows nothing, as does "ircat mythtv".

Can somebody suggest what I'm missing here?

Thanks.

Addendum: (damn you systemctl!)
Just noticed this:

Not entirely sure what systemctl is trying to tell me there.
I have this in /dev

Code: Select all

# ll /dev/lirc*
lrwxrwxrwx 1 root root     10 Sep 20 14:56 /dev/lirc -> /dev/lirc0
crw------- 1 root root 251, 0 Sep 20 08:42 /dev/lirc0

Okay, call off the dogs.

I read what I posted above and found the error was in the config for /etc/sysconfig/lircd. Specifically I needed to comment out line 15:
#DEVICE=/dev/lirc/0

and uncomment line 19
DEVICE=/dev/lirc

Then I just restarted lircd.

Two observations:
1. My troubleshooting is greatly enhanced simply by trying to articulate the issue to someone else.

2. This issue has been plauging me for almost 2 years now. Shouldn't it be fixed so that it works out of the box?

For me, it is posting for help, and about 2 minutes later finding the solution.

No bug report means it takes longer to get fixed.
It almost worked out of the box on Mageia Release 3. Could be I could have made a configuration change in mythtv but what I did:

Created the tv remote key/code files.
Copied /usr/lib/systemd/system/lircd.service to /etc/systemd/system/lircd.service and changed
ExecStart=/usr/sbin/lircd --driver=default --device=/dev/lirc0
to ExecStart=/usr/sbin/lircd --driver=default --device=/dev/lirc0 -H udp -d 6546
Then just to play is safe:
systemctl --system daemon-reload
systemctl disable lircd.service
systemctl enable lircd.service
systemctl restart lircd.service

and now my remote works with MythTv

Interestingly, this is often the case. If you describe a problem thoroughly and comprehensively
so that an outsider would understand it properly, really often this already contains important clues
to the solution or you can solve the problem yourself by reading the explanation.

Quick note: After 15 days uptime I rebooted the system and lirc stopped working. Chanted the line in /etc/sysconfig/lirc to:

Code: Select all

DEVICE=/dev/lirc0


Seems to have fixed it. Not sure why it regressed.

Really annoying.
