    Hi,

    I'm trying to set a mode with xrandr for my screen but it fails and return this error:

    Code:
    xrandr: Configure crtc 0 failed
    The mode I'm trying to set is the preferred one detected for that screen:

    Code:

    Same screen on another machine (udoo ultra or PC) works good and preferred mode is set as current when plugged.

    Are you sure the proper Xorg driver installed?

    https://gitlab.freedesktop.org/xorg/driver/xf86-video-amdgpu

    What does bellow display?

    Code:
    cat < /var/log/Xorg.0.log | grep amdgpu
    
    Code:
    # Make sure amdgpu DRM diver if built as a kernel module
    # As it requires firmware from linux-firmware-amdgpu
    # From above looks like it's loaded
    $ lsmod | grep amdgpu
    $ modprobe drm amdgpu
    
    Just realized you are using weston (Wayland). Think xrandr is Xorg specific.
    Will probably need to utilized another program.

    Maybe try

    Code:
    $ apt-file search wlr-randr
    $ sudo apt install wlr-randr
    # I haven't used weston on Ubuntu, but you may or may not run into bellow
    # compositor doesn't support wlr-output-management-unstable-v1
    # The version of weston you are using may support the interface
    
    Sure there's some project out there.
