    Hello,
    I have a 2560x1080 display on the Raspberry Pi4. I cannot rotate the display. My settings are:

    @lxpanel --profile LXDE-pi
    @pcmanfm --desktop --profile LXDE-pi
    @lxterminal
    @leafpad
    @xrandr --output HDMI-1 --rotate right
    @xscreensaver -no-splash@
    

    and /boot/config.txt:

    hdmi_safe=1
    hdmi_drive=2
    hdmi_ignore_edid=0xa5000080
    hdmi_aspect_21_9=7
    hdmi_pixel_freq_limit=400000000
    hdmi_cvt=2560 1080 50 7 0 0 1
    config_hdmi_boost=4
    max_framebuffer_width=2560
    max_framebuffer_height=1080
    framebuffer_width=2560
    framebuffer_height=1080
    display_rotate = 2
    avoid_warnings=1
    hdmi_group=2
    hdmi_mode=87
    hdmi_force_hotplug=1
    dtoverlay=vc4-fkms-v3d
    max_framebuffers=2
    

    Can somebody help me?

        @wuermchen there should be an option in the raspi-config program (run from a terminal window) for rotation

        sudo raspi-config

                @wuermchen I think your original problem was in /boot/config.txt where you had spaces around the equal sign for display_rotate.

                  I found the mistake. The HDMI cable was defective. I installed a new cable and now it automatically detects the resolution. The display is now correctly rotated.
