List supported remotes $ ls /lib/udev/rc_keymaps/ # If the /etc/lirc folder exists on your system, remove that as well Remove lirc entirely from your system $ sudo apt-get purge lirc The following are the steps that lead me to successfully configure the remote controller on Ubuntu 18.04 LTS: So basically it should be possible to make IR work also without lirc, using kernel-specific drivers. Using that, pressing an up-arrow on the remote works the same way as pressing the up-arrow on a keyboard. Recent Linux kernels have built-in support for IR remotes. In the end I should have read the lirc documentation more carefully, as it states clearly

It worked for me and I was able to see the configuration screen, but in the end the outcome was the same: I couldn’t see the signals from the IR sensor. A workaround is explained on this blog, but basically involves installing a previous version of lirc from Ubuntu 16.04 packages. Later I discovered that there is an annoying bug on Ubuntu 18.04 that prevents lirc configuration during the installation process. I also tried to cat into the device $ cat /dev/input/event9Īnd pressing buttons on the remote should have printed something, but this was not the case.
Ehome infrared receiver not working drivers#
Following the documentation I tried to manually configure the device and the driver using variations of the following command, to get the kernel output available for lirc drivers $ mode2 -driver default -device autoīut it didn’t show anything. Even running the command $ sudo dpkg-reconfigure lircĭidn’t work out.

Install lirc using the Ubuntu-specific package $ sudo apt-get install lircĭuring the install process I should have seen a configuration window, but that was not the case.

Most remotes use the NEC protocol, including my old United LCD TV remote control. Sharp use in VCRs that are produced by Sharp.RC5 and RC6 are the IR protocols defined by Philips.Furthermore, since ir-keytable finds the device you know that the driver is part of the rc subsystem.”įor what concernes the protocols, we can see that the receiver supports most of them: “If you get this kind of output you know the event device ( /dev/input/event9) and the kernel module loaded ( ite-cir).

Most of the guides available on the Internet suggest to install LIRC (Linux Infrared remote control), which is an open source package that allows users to receive and send infrared signals with a Linux-based computer system. After turning on the computer press F2 (or any other key that you use to enter the BIOS) and check the menu to find the status of the IR sensor. First stepsįirst thing you need to check that the IR sensor is enabled in the BIOS. Some of these information are quite technical and require some level of expertise.
