Hi,
how can I change the orientation of the screen?
I tried this (working on a ZYNTHIAN distribution:
dtoverlay=vc4-kms-v3d
dtoverlay=vc4-kms-dsi-7inch,rotate=180
It lights up, but orientation does not change. I need to change upper/lower direction. Thank You in advance.
Regards
Thomas

Are you using a Raspberry Pi development board? What operating system are you using? You can try using the following command:
xrandr --output HDMI-1 --rotate normal
xrandr --output HDMI-1 --rotate left
xrandr --output HDMI-1 --rotate right
xrandr --output HDMI-1 --rotate inverted
xrandr --output HDMI-1 --rotate normal
xrandr --output HDMI-1 --rotate left
xrandr --output HDMI-1 --rotate right
xrandr --output HDMI-1 --rotate inverted
It is a raspberry Pi 3. The OS is Zynthian, based on raspi OS.
The display is connected with the display connector onboard (DSI Display Interface), not hdmi output.
As I understand Your commands, they are for HDMI. Where should they be placed? I tried them in the terminal, but they are usefull for X Server. Zynthian has no X Server.
My actual commands are in the config.txt.

I'm sorry for the misunderstanding earlier. We haven't tested this system before. You can try referring to the official website for methods to rotate the DSI screen.

Thank You very much !!
This was the information I was looking for.
For the people stranding here while their search:
Display orientation ...
In cmdline.txt: Add video=DSI-1:800x480@60,rotate=180
Touch orientation ...
In config.txt find
# Display Config
dtoverlay=vc4-kms-v3d
dtoverlay=vc4-kms-dsi-7inch
and change the last line to
dtoverlay=vc4-kms-dsi-7inch,invx,invy

No worries! If the system hasn't been tested before, checking the official website for guidance on rotating the DSI screen is a good start.Luckfox Taylor wrote: ↑2024-03-21 3:03 I'm sorry for the misunderstanding earlier.
