Unable to rotate screen Raspberry Pi 4

KaaaaasKop

Hello there! I have a problem with rotating the screen.

Pi Model or other hardware: (4B)
Power Supply used: (Powerbank)
RetroPie Version Used (4.7.1):
Built From: (retropie-buster-4.7.1-rpi4_400)
USB Devices connected: Controller
Controller used: IPEGA

The config.txt display_rotate does not work, and I am to understand this is because of how Raspberry Pi 4 uses a different driver or something, so I tried doing it at autostart.sh with --screenrotate 1, but for some reason, I cannot save it, only exit it with ESC or CTRL+C, but I cannot save it. I cannot go to the 'OK' and 'Cancel' parts of the autostart.sh file in the retropie config.

I have also tried using xrandr in the terminal, but I get the feeling that is something related to a different OS...

I also tried #dtoverlay=vc4-fkms-V3D, but then it won't boot, even though the screen rotates then. Something about GPU I believe?

I have been trying things for hours, but I just can't figure it out because I don't know what I'm doing. I can play the games, but I want landscape orientation rather than portrait. (So horizontal instead of vertical.)

What should I do? Thank you in advance!

KaaaaasKop.

You need to use the Tab key to exit the editor and be able to press Ok/Cancel.

Don't modify the config.txt and remove the vc4-fkms-v3d overlay, that's not a supported configuration and RetroPie will not work (you've already experienced it).

@mitu Thank you! That worked, now to figure out how to make the resolution work and how to make the games rotate properly, and after that I can FINALLY enjoy my first attempt at my own retro handheld :)

Here's a similar post with some hints. For the resolution, EmulationStation supports setting it via the parameters, so you can modify the autostart.sh with

emulationstation --screenrotate 1 --resolution <width> <height>

to have it start with the rotated resolution.

@mitu Thank you! Resolution gave weird results, but screensize seems to work :) For emulationstation that is.

I also managed to rotate the screen properly for the games, but they only have a very small box in the middle, the rest is black. I shall figure this out, and once I do I can finally play, haha.

@kaaaaaskop Did you ever sort this out? I’m at the same position you were when you posted this.
