Why is my display in portrait mode?

[maciekish]

Hi, i have a Rapsberry Pi 4 and a Hyperpixel 4.0. I used the normal setup script and selected "1" - "Rectangular Hyperpixel and Pi 4". After reboot my display works but its in portrait mode. Whats wrong?

[Gadgetoid]

Run the command hyperpixel4-rotate left or hyperpixel4-rotate right to rotate screen and touch.

It's actually a portrait screen but the Pi4-native commands to rotate it don't work until it's installed/rebooted, thus the weird default and the need for hyperpixel4-rotate.

That command didn't work for me, I tried both with and without sudo, tried both rebooting and full power downs

The touchscreen directions are now reflecting the change, but the screen display itself is still portrait, I used "left" for "hdmi is down". In fact, none of the directions work

I did a cat /var/log/syslog | grep -i hyperpixel

Please help

EDIT:

I don't know if this is by design, but it works if you actually just go into the GUI Screen Configurations to do the rotation. The command is still needed because of the touchscreen coordinates, but it seems like, at least for me, the screen only rotates when you go into the Screen Configuration item inside the start menu, the command is not what rotates the screen. So... problem solved, sort of? I feel like either there's a bug or the documentation isn't clear enough.

Hi there. I know this thread is old and you've probably resolved the issue, but if you're using a headless set up over SSH the command just has to be prefixed with "DISPLAY=:0.0", so the full command would be (no need for sudo):-

"DISPLAY=:0.0 hyperpixel4-rotate left"

"left" can be replaced with "right", "inverted", "normal". can confirm I haven't yet found a way to boot into landscape.

Hope this helps.
