Rotate the display 2560X1080 Raspberry Pi4

wuermchen

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

that does not work

@raf yes, thanks. That is where it was

@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.
