Hello escalade,
I progressed a little:
- in LE:
- fbset -g 1920 1080 1920 1080 32 (to enable the frame buffer device)
- systemctl stop kodi (to stop Kodi)
- in the Docker container
- apt install firefox xorg -y (to install Firefox and X.org)
- startx -- :0 & (to start X.org)
- DISPLAY=:0 firefox (to start Firefox)
Firefox displays on the screen.
I however had stop stop Kodi to display Firefox on the screen.
I had copied the /etc/X11/xorg.conf.d/10-inputs.conf you provide, but the keyboard remained unresponsive.
Had you managed to display Firefox on top of Kodi? Do you remember how?
As for the keyboard, I have a feeling that a link is missing between LE and the container. What do you think.
Thank you for any help further.
