display_rotate not working after update

kikeminchas

First of all, since this is my first post, hi everybody and thanks so much to the people that make this possible... I have just finished building a small custom arcade cabinet. I used an old LCD that had much better viewing angles if mounted upside down (I'm using an Ikea table as frame) so I am using the display_rotate=2 to rotate the display 180 degrees. This was working fine until today when I did an update to all retropie packages. I'm using Retropie 4.6. with a RPI4. Since today the option does not work anymore, no other changes in configuration. The option is still present in my ocnfig.txt and I even tried display_hdmi_rotate instead. Any idea if this option has been deprecated/changed or if there is any other alternative? (or if this is just a bug introduced in some of the packages/kernel with the latest update?

Thanks!

It seems to be ignored on the latest kernel/firmware. You can restore the rotation by modifying /boot/cmdline.txt and adding at the end of the line:

video=HDMI-A-1:1920x1080M@60,rotate=180

replacing the resolution with your display's native resolution.

@mitu thanks a lot! This works, mostly.... In ES and Retroarch the display is rotated but videos like the splash screens or the video previews are not rotated? Any idea why this is? Otherwise I think I can live with it until a new update hopefully fixes the previous option

They may be using the dispmanx layer, which is not rotated.

Looking at the topic I started here, it doesn't seem to be a bug, but the way it's supposed to work. Are you using omxplayer for video previews ?

@mitu strange, so it means option working before was just an extra with no warranty? I am using OMX, yes.

mitu

Looks like it, yes.

For the splashscreen videos, I think this can be remedied by passing the --orientation parameter to the call in /opt/retropie/supplementary/splashscreen/asplashscreen.sh, but for the video previews in EmulationStation, I don't have a solution.

Thanks for your help. I disabled OMX from ES and videos play, although are not properly scaled to the interface/theme. Now, for some reason I lost audio completely (using the 3.5mm jack, not HDMI audio). I think I'm going to start from scratch and not update for the moment.

@kikeminchas That's also because of the update - see this post. You can revert the audio to the previous settings by adding snd-bcm2835.enable_compat_alsa=1 to the /boot/cmdline.txt, or modify the .cfg settings file for EmulationStation (as a workaround).
