Using fb1 (Touchscreen) instead of fb0 (HDMI)?



  • Hey Guys,

    I bought a 3.5inch TouchScreen (XPT2046 ChipSet) and got it ALMOST to work with RetroPie.

    I have to use this to boot RetroPie on Touchscreen:
    First I run the command "fbcp &" from the Terminal (on Debian Jessie Desktop).
    After that, I run "sudo pkill Xorg" following "sudo systemctl stop lightdm && emulationstation".
    RetroPie boots, Screen is on HDMI AND Touchscreen, like in this video:


    As you can see in the Video, the fps is like 15-20fps which are not good enough to play smoothly.

    How can I get RetroPie to show the GUI and the Games on TouchScreen instead on HDMI?
    I changed "fb0" to "fb1" in /usr/share/X11/xorg.conf.d/99-fbturbo.conf already but it doesn't affect on RetroPie.
    The TouchScreen just show the console of RetroPie (means if I open raspi-config through RetroPie, it will be displayed on Touchscreen)

    The TouchScreen works normally on Raspbian though...

    Anyone who can help me with that?

    @CellenseresPi I don't think you will be able to get decent performance out of this sort of screen - you need one that connects via hdmi or composite.



  • Could you recommend a good & cheap HDMI Touchscreen which works for RetroPie?
    from 3.5inch up to 5inch would be nice (with Case).

    Thanks in advance!"
