hi Lionel,
I tried to do the same with a M14t screen from lenovo without success (see Gsetting command to activate touch screen on external monitor). So sorry to hijack this thread, but could you explain how you find 1a86:e2e4/ output "['Unknown', 'Linux FHD', 'Linux #0']" ? If it’s not the right place, I will complete my original post.
I tried with gsettings set org.gnome.desktop.peripherals.touchscreen:/org/gnome/desktop/peripherals/touchscreens/2d1f:524c/ output "['LEN', '25251', '1194738522']" but it didn’t work.
