Lirc - could not open /dev/lirc

I've been running MythTV 0.15 on FC1 for a while, but ran into some
problems with 0.16 and decided to reload with Fedora Core 2 and MythTV
0.16. I have almost everything working except for a couple things.
I'm having somewhat interesting issues with Lirc. I setup MythTV
following Jarod's excellent guide and I also set it to start up
automatically. When this happens Lirc does not work. However, if I
execute the following commands and restart mythfrontend then Lirc
works fine.

[root[at]localhost mythtv]# /sbin/depmod -a
[root[at]localhost mythtv]# /sbin/modprobe lirc_i2c
[root[at]localhost mythtv]# /sbin/service lircd start
Starting infrared remote control daemon: [ OK ]
[root[at]localhost mythtv]# exit
exit
[mythtv[at]localhost mythtv]$ /usr/bin/irw
00000000000017e5 00 OK hauppaugegrey

Now if I reboot Lirc stops working again. I'm running Fedora Core 2
with MythTV 0.16. I have one PVR-250 with the Gray Remote. Here's
some info that may help:

[mythtv[at]localhost mythtv]$ cat /etc/modprobe.conf
alias eth0 via-rhine
alias snd-card-0 snd-via82xx
install snd-via82xx /sbin/modprobe --ignore-install snd-via82xx &&
/usr/sbin/alsactl restore >/dev/null 2>&1 || :

lirc_dev: IR Remote Control driver registered, at major 61
lirc_i2c: chip found @ 0x18 (Hauppauge IR)
lirc_dev: lirc_register_plugin:sample_rate: 10

Here's /var/log/messages after rebooting and loading MythTV:

crw-rw-rw- 1 root root 61, 0 Oct 11 13:34 /dev/lirc
srw-rw-rw- 1 root root 0 Oct 25 20:40 /dev/lircd

In a previous post someone suggested going back to Lirc 0.7.0pre7, but
unfortunately I'm not sure the best route to do that. If that is the
answer can someone give me some tips on how to revert back?

Thanks,

Brian

That is the same exact symptom that I have. Strange. I also have a
FC2,. PVR-250 and the latest ivtv/mythtv from ATrpms. The only thing
different, I believe, is that I have to stop lircd first before I
depmod/modprobe and restart lircd.

I too wish I could find out why this is, too. I'll monitor this post!

RE: Lirc - could not open /dev/lirc [In reply to]

I don't know if this will help or not but when I had that problem 2 days ago
with my x10 lola for some reason lirc was saying my remote codes were
different than what they were when they were working before my upgrade. I
did an irrecord and pressed several buttons and I noticed they were pretty
much all different. I remade a new lircd.conf and restarted lircd then irw
showed the proper button presses.

The commands above are for the current session, if you want to make
them persistant across reboots, you'd have to edit /etc/modprobe.conf
and use chkconfig.

Thanks for the help so far. I did try the chkconfig command, but it
still does not work. I think it was "/sbin/chkconfig lircd on". Here
is my current /etc/modprobe.conf file. What additional lines would
you suggest I add?

[mythtv[at]localhost mythtv]$ cat /etc/modprobe.conf
alias eth0 via-rhine
alias snd-card-0 snd-via82xx
install snd-via82xx /sbin/modprobe --ignore-install snd-via82xx &&
/usr/sbin/alsactl restore >/dev/null 2>&1 || :

RE: Re: Lirc - could not open /dev/lirc [In reply to]

Make sure in your /etc/modules.conf you have a line that says something like
this

alias char-major-61 lirc_xxxx

It can be whichever lirc module you use... Here are the ones to choose from

lirc_atiusb.o
lirc_bt829.o
lirc_dev.o
lirc_gpio.o
lirc_i2c.o
lirc_it87.o
lirc_mceusb.o
lirc_serial.o
lirc_sir.o

Goodluck.

Re: Re: Lirc - could not open /dev/lirc [In reply to]

Unfortunately, I have no suggestions for the OP, short of backing off to
lircd-0.7.0pre7, since lots of folks seem to have had problems with pre8, but
I would certainly like to clear a few things up here...

Er, Johnny, look at the stuff you quoted. He already has that in his module
config file, which by the way, is not /etc/modules.conf,
its /etc/modprobe.conf.

This isn't quite correct. The .o part should be left off. And by the way, the
modules are .ko w/2.6 kernels, which his distribution uses.

'chkconfig lircd on' is sufficient. The default is --level 345, so there's no
need to include the level flag.

Not sure if you ever got the tip on how to do this or not, so here goes...

First, start off with an apt-get update, so your local metadata reflects the
reality of what packages are out there. Next, fire off the command "apt-cache
policy lirc". This should return some info similar to this:

$ apt-cache policy lirc
lirc:
Installed: 0.7.0-38_pre7.rhfc1.at
Candidate: 0.7.0-41_pre8.rhfc1.at
Version Table:
0.7.0-41_pre8.rhfc1.at 0
996 http://apt.atrpms.net fedora/1/en/i386/at-testing pkglist
0.7.0-40_pre8.rhfc1.at 0
996 http://apt.atrpms.net fedora/1/en/i386/at-testing pkglist
0.7.0-38_pre7.rhfc1.at 0
996 http://apt.atrpms.net fedora/1/en/i386/at-testing pkglist

Judging from this output, what you want is:

apt-get install lirc=0.7.0-38_pre7.rhfc1.at

You'll need to do something similar for lirc-lib and
kernel-module-lirc-`uname-r` I believe.

Re: Re: Lirc - could not open /dev/lirc [In reply to]

modules.conf vs modprobe.conf depends on the distro. Gentoo uses
modules.conf. they do pretty much the same thing

And I also know that.

I was pointing out that Johnny's advice was mostly useless, because he didn't
read very carefully, as the OP stated he had the lirc line already in
his /etc/modprobe.conf file.

Brian,
Did you ever get lircd to work after boot? I'm still having off and on
success.
