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

remove snd-via82xx { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; };
/sbin/modprobe -r --ignore-remove snd-via82xx

install lirc_i2c /sbin/modprobe ivtv; /sbin/modprobe --ignore-install lirc_i2c
[mythtv[at]localhost mythtv]$ dmesg |grep lirc
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:
Oct 25 20:28:57 localhost lircd 0.7.0pre8[2251]: accepted new client

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
