[PROBLEM] Trouble getting lircd to work as expected, also is something else handling IR input?

[hge]

I have exactly the same problem as Msprg. My RC worked fine until kernel linux-image-bcm2836 4.14.102+-1555993600 from Debian Stretch. With newer kernels some keys on the RC did not work (i guess it's related to "IR decoding with BPF" as described in https://lwn.net/Articles/759188/ ). I stood on the 4.14 kernel for quite a long time, but finally wanted to update to Buster. Since the upgrade did not work as expected I reinstalled Xbian from scratch, and now I have a quite clean Buster system.

Since the kernel decoding doesn't seem to work correctly with my remote i tried to use LIRC again. First of all you have to install a missing library (see errors in /var/log/upstart/lirc.log):

# apt install libusb-0.1-4

Also make sure that lircd is started in xbian-config.

Now all keys work, but... some keys cause duplicate events. It seems that all key presses are reported via LIRC, and some are also reported via the kernel interface. So I guess I have to deactivate the kernel decoding. I have to investigate how this can be done...
