G_DIETPI_VERSION_SUB=25
G_DIETPI_VERSION_RC=1

G_GITOWNER='MichaIng'

• Distro version | bookworm

- Kernel version | Linux MMDPi 6.1.31-sun50iw9 #1.0.2 SMP Mon Sep 25 13:54:37 CST 2023 aarch64 GNU/Linux

• Architecture | arm64

• SBC model | Orange Pi Zero 3 (aarch64)

• Power supply used | Official Raspberry Pi adaptor

• SD card used | Samsung

Steps to reproduce

1. xrandr doesn’t return any displays at all
2. To rotate display I’ve used the following from here - DietPi-Config | Add option for rotating screen in X session · Issue #5585 · MichaIng/DietPi · GitHub

Section "Monitor"
        Identifier "Monitor0"
        Option "Rotate" "right"
EndSection

Section "Screen"
        Identifier "Screen0"
        Device "Card0"
        Monitor "Monitor0"
EndSection

3. Screen roates but frames per second in Chromium drop to practically nothing.

Expected behaviour

• Would expect performance to be the same.

Actual behaviour

• Screen renders and rotates, but frames per second drop to practically nothing.

did you test behavior on original Orange Pi Debian? Does it behave similar or can the screen rotate without issues?

I have not, sadly have limited resources available at the moment, I have read people have managed to do this, but they’ve not been specific with regard to performance issues.

I’m wondering if there is a way to fully rotate at boot, opposed to editing the 98-dietpi-disable_dpms.conf, in all honesty though out of my comfort zone I’m hacking around!

edit - will try and get hold of another sdcard
