HP RC6 remote control transceiver not working
« on: December 31, 2023, 10:53:52 am »

Greetings, and happy new year to all!

I am a long time user on Windows, just installed MC31.0.83 on Linux Ubuntu (very easy), congratulations to the extended team, for MC client machines I am now ready to ditch Windows, huge progress done.

Last issue to me, MC31 does not recognize my old HP RC6 remote control USB transceiver that I use with a Logitech Harmony remote.  Both remote and transceiver function correctly in Windows.

In the Tools/Options/Remote Control windows, it says that I do not have a transceiver connected.
Same goes for the Windows version of MC31 (31.0.87 on Win 11), but the Logitech works perfectly in Windows, while in the Linux version only the directional keys are recognized.

Any suggestion?

After doing a quick search, it appears that HP RC6 remote + receiver may not be supported in Linux at all, at least all the search results I found are of users trying to use it and not really finding a solution. You should check and see if it's even seen by the OS at all as any sort of input device. Maybe it detects it as a keyboard or something?

This thread is 14+ years old, but it does go into the issues of using that remote in Ubuntu: https://ubuntuforums.org/showthread.php?p=6775769

Thank you.  I will continue to search.

Is there a recommended IR remote solution for MC Linux, preferably with a USB transceiver compatible with my existing Harmony remote?

Cheers.

It appears "Recent Linux kernels have built-in support for IR remotes" :
https://mauricius.dev/configure-an-infrared-remote-control-with-linux/

My fresh install of Ubuntu 22.04 needed
Code: [Select]
$ sudo apt install ir-keytable

But still only the 4 directional arrows recognized by MC31.

So if everything is already there, is it possible somehow MC31 does not connect to those kernel drivers?
(I have not installed LIRC, it is still the basic installation of Ubuntu 22.04))

Cheers.

You may be interested in some recent discussion about IR remotes on Linux in this thread:

https://yabb.jriver.com/interact/index.php/topic,136975.0.html

The basic issue is that Ubuntu's desktop environment (Gnome) consumes media keypresses.  You can work around this in various ways, but the last post in that thread offers a particularly interesting suggestion.

I am running on Manjaro/KDE and I have a generic RC6 receiver and a Windows Media Centre remote I got off ebay and I get volume up/down, GreenWindows button jumps to Theatre view and the direction arrows / OK work.... but that's about it. Would be nice if there was more.

Whats more annoying is the media keys on my Corsair Straffe v2 keyboard dont do anything in Linux in MC but also in Spotify and maybe others, but the volume wheel works. 

I know there are KDE settings for keyboard shortcuts inc media keys, but I have not had a chance to dive into the details as referenced by mwillems?

Happy new year all...

Thank you mwillems, I will have a look.

If I succeed, I will post a follow up.
