@mitu ooohhhhhh!! That was the key, I only had the reference and was missing the actual -code- . Problem solved. Noy I get the video flipped. Thank you so much for your help.

I meant to send a PR myself, but looks like the Github's web interface didn't go through with it. I've amended their Wiki page with the command line options and sent a small PR to fix the sample .conf from the repository.

@mitu the method is still in config.txt so I guess it refers to Raspi OS as you said.

For the touchscreen it uses a command in the file usr/share/X11/xorg.conf.d/40-libinput.conf

Thank you @mitu

I will have to chase an older model pi. Now I regret not buying the 3b that I saw gathering dust at one shop a couple of months ago.

@sleve_mcdichael xrandr only works when X is running, so the setting won't persist in a pure commandline/framebuffer environment, like retropie on the pi. as soon as you exit the desktop, everything is back to how it was, as far as i'm aware.

you can attempt to run retropie within X, of course, but that's not a supported configuration. however it's probably the path of least resistance for non-standard display setups (rotated, CRT, etc), as xrandr is so powerful...

The Pi4 doesn't support the rotate_display parameter anymore - see https://www.raspberrypi.org/documentation/configuration/config-txt/video.md. At some point, it was possible to use display_rotate=2 to flip the screen, but after a firmware update this year, this is also no longer supported.

There is some guidance on how to rotate the display on the Pi4 here or at a similar post here in the forums.

@T0biasCZe I actually am looking into this same thing. I was able to successfully rotate the screen 90 degrees for only the desmume emulator everything else stays horizontal, however the touch screen doesn't work.(my issue with it) I have not been able to figure out how to get drastic to flip vertically as it does work with a touchscreen. I have an image of what my desmume looks like with the change.

You will want to access the NDS folder and look for retroarch config file. retropie/configs/nds/retroarch.cfg. This will load an override config for the NDS emulator when it launches. Next you will want to edit it. I connect with Windows and make the change in Notepad++. You will want to add the line line video_rotation = "1" or video_rotation = "3" above the #include line. That should turn your screen the other way.

Another way it could be edited is to go in through the Retropie settings and choose Retroarch. Once there settings -> video-> output-> video rotation. after you make the change here go back to the rtroarch main menu you should see the configuration file. save as new config. You should be able to use that new file in place of the retroarch.cfg.

@t_mitch Mame4All is not a Libretro emulator, so the hotkey combination don't apply (and also the .cfg file has no effect). But you found the solution, so that's good.

@jerryb said in Screen Orientation issues on my 'Coffee' Table....:

Not sure I would use RetroArch for this. I would add a rom_name.zip.cfg file to the folder.

the text of the file would be

video_rotation = "2"

This will rotate the screen 180 degrees. 1 would be 90 and 3 would be 270 degrees.

so for your Pac-Man rom is nameed pacman.zip you would create a file called pacman.zip.cfg (txt file) with the above line added to it. (again this goes in the same folder as the rom)

If you need more assistance you may want to add more detail about you build as mentioned here

https://retropie.org.uk/forum/topic/3/read-this-first

Hope this helps.

Tried your suggestion to no avail, but gone through RetroArch settings whilst in game...

Main Menu->Settings->Video (set rotation to 180 degrees)
Quick Menu->Configuration Override Option-> (Save Game Overrides)
Exit back to game

Sorted.

@blackshadow said in Screen rotation for Retropie GUI:

quick copy and paste from another site to save me writing it out lol

Step 1 – Edit Config.txt

Start by editing the config.txt file ether via the sd or with:

sudo nano /boot/config.txt

Add one of the following lines to the bottom of the file :

display_rotate=0
display_rotate=1
display_rotate=2
display_rotate=3
0 is the normal configuration. 1 is 90 degrees. 2 is 180 degress. 3 is 270 degrees.
If you are using the Official Raspberry Pi touch screen you can use “lcd_rotate” rather than “display_rotate”.

Save the file by using CTRL-X, Y then ENTER.

as the site you linked references the 7inch pi screen ill assume thats what your using you can use the lcd_rotate that is mentioned as apposed to display rotate

Thanks. This needs the thumbs up as all other routes didnt work. This. Yes. Thanks
