hello everyone! so I have a problem trying to hook up my ubuntu (either 18.04 or 21.04) to work with ir receivers. however with kodi it works out of the box.
so my question would be, what could be the difference between kodi and ubuntu settings that it works out of the box with one and not at all with the other? i've been reading all kinds of tutorials and wiki pages trying to make it work but no success. my ir receiver is a homebrew serial port one, here's what I was doing on my ubuntu machine:
- installed lirc
- used the command "setserial /dev/ttyS0 uart none"
- after this "modprobe serial_ir"
- set up /etc/lirc/lirc_options.conf
(driver=default, device=auto, also added setserial and modprobe under [modinit])
- restart lirc/reboot
- trying to read output of mode2 and ir-keytable too
output of ir-keytable

however, the most interesting part is that i tried another pc, and it seems to work with what i was doing (setserial, modprobe, mode2), but on this one not. this pc only accepts ir signals with kodi. dont remember now exactly but checked kodi's /etc/lirc/lirc_options.conf file and it was either identical or I tried to copy over from kodi. what could be different between kodi lirc vs ubuntu lirc settings? I am completely clueless now. for sure the serial port, remote and ir receiver work separately.
