Ah, ok. You can expect all kinds of performance issues if you use higher resolutions. That's why 1080p is forced by default to provide consistent user experience.
rc_keymap.txt needs to have UNIX line endings so use a proper text editor (Windows notepad won't do) or look into tools like dos2unix.Hi @KonstaT, I'm trying to use an IR receiver with this build. The feature is enabled from settings (as in FAQs), ir-keytable finds the device and ir-keytable -t detects the key pressures on the remote. When I make a keymap for any remote and place it as /boot/rc_keymap.txt and try ir-keytable -w I'm getting "invalid parameter on line 1", but if I rename it to rc_keympap.toml it loads succesfully as I can see with r-keytable -r and whith ir-keytable -t during key pressures. The thing is that the remote has no effect outside the terminal. The only relative issue I found is in your thread at forums.raspberrypi.com.
Any enlightenment would be appreciated!!!
Thanks in advance...
Otherwise the RC is just exposed as regular Linux input device and it works like any keyboard. You should also see the input events with 'getevent' tool if you have it working properly.
