My ongoing experiences with Ubuntu, and later Mythbuntu, as a media center with MythTV. I'm also using the system for a virtual machine server, a mediawiki server and a general all around home infrastructure base.

LIRC and Remote working with Ubuntu and MythTV

Next step was setting up the remote. I have the Grey Hauppauge remote with the 4 color buttons at the bottom, model A415-HPG (confirmed via a sticker inside the battery compartment).

I followed the directions on the LIRC_on_Ubuntu_Edgy_Eft page, with the following exceptions:
  • My lirc device was /dev/lirc/0 and not /dev/lirc0
At this point I fired up the lirc deamons and things seemed to be working in that irw reported key presses (although, yes it was reporting "Hauppauge_350" when I have a 250):
$ irw
00000000000017b7 00 Record Hauppauge_350
0000000000001790 00 Vol+ Hauppauge_350
00000000000017b5 00 Play Hauppauge_350
00000000000017b2 00 Rewind Hauppauge_350
00000000000017a4 00 Replay/SkipBackward Hauppauge_350
00000000000017a4 01 Replay/SkipBackward Hauppauge_350
0000000000001790 00 Vol+ Hauppauge_350
But it still wasn't working with MythTV at this point.

So I poked around on the following sites:
I didn't seem to have lirc support build into MythTV ("native LIRC support"), at least creating a ~mythtv/.mythtv/lircrc file didn't do anything (as described here). I'm not sure how you determine this for certain.

I also didn't have irxevent installed. I figured out I had to install the lirc-x package to get irxevent:
# apt-get install !$
# which irxevent
/usr/bin/irxevent
I then created ~/.lircrc from http://gentoo-wiki.com/HOWTO_Setup_MythTV/Hauppauge_lircrc

Update 4/20/2007:
Looks like adding irxevent to my ~/.xinitrc file doesn't work with Gnome. Instead under System/Preferences select Sessions. Then click on the Startup Programs tab, then Add and enter irxevent --daemon. Then Close.

Back to original text...

At this point I could run irxevent and I could see that IR events were being translated into keystrokes for my Terminal window. I fired up MythFrontend and things sorta worked. By that I mean the arrow keys didn't work for the opening menu and once I started watching TV things worked after I hit enter on the keyboard once. Not ideal.

So after some editing to my .lircrc file it looks like the following. It's working fairly well, but changing channels is still clunky. It seems like I have to hit enter after channel up/down to make the change take effect. I suspect some problem with MythTV since I see the same issue with hitting the up/down keys on the keyboard.
