Recent update breaks remote control

[declanmullen]

My mythbuntu 10.10 system including its lirc managed remote control has been working fine. I've recently done some updates (see below) and now the remote doesn't work correctly (only some of its keys seem to work). I suspect that lirc is no longer managing the remote and now instead the remote is now being treated like a keyboard.

How do I get lirc managing my remote control correctly again, thanks ?

Before the updates the kernel was:


$ uname -a
Linux pvr 2.6.35-28-generic-pae #50-Ubuntu SMP Fri Mar 18 20:43:15 UTC 2011 i686 GNU/Linux


I suspect that one or more of the below updates are to blame (extracted from /var/log/apt/history.log):

BTW, booting off the previous kernel 2.6.35-28 does not fix the problem.

The remote control receiver is the one that is built in to the Leadtek WinFast DTV2000DS DVB-T TV card. The remote control is the Y04G0051 model. http://www.linuxtv.org/wiki/index.php/Leadtek_WinFast_DTV2000DS

I'm using the generic "devinput" configuration file with lirc. http://lirc.sourceforge.net/remotes/devinput/lircd.conf.devinput

It wouldn't have anything to do with this topic would it ?

Problem solved. It turned out that the updates had resulted in a change to the name of the device file thru which the remote's events were being made available.

Prior to the above updates the device file was /dev/input/event4
After the above updates the device file was /dev/input/event6

I just had to update the /etc/lirc/hardware.conf file to specify the new file name and then restart lirc.
