Hi guys, I'm working on my own set of augmented reality glasses, and am using a raspberry pi 4 as the computer for it l. The thing works fine, but the display is horizontally flipped. Is there a way to change the orientation of the display with commands in the terminal or editing config.txt? Any help would be appreciated, couldn't find much info on this topic anywhere really π
mega_destroyer
Oh yeah and for further context I'm just using the normal 32bit version of raspbian you find on the front page of the imager
mega_destroyer
For even further context this is exactly what you see when looking through the viewfinder
mega_destroyer
You can see that the pi logo which is by default in the top left corner is now in the top right corner
mega_destroyer
the mouse is also horizontally flipped

Any help at all would be greatly appreciated π

> 1. Open Menu > Preferences

> 4. Select Orientation and choose one of the four options
> 5. Click the green check to confirm and apply the new orientation

Rotation is not the same as flipping the display horizontally
mega_destroyer
That's the problem
k9t33n
ah yes I see
mega_destroyer
Is there a way to do it with xrandr
k9t33n
not sure, now I see what you mean by it not being documented
mega_destroyer
Yeah
k9t33n
in screen config is Flipping it or something similar there?
mega_destroyer
You can invert it but I think it does both horizontal and vertical which is not what I want
mega_destroyer
Just let me know if anyone gets any sort of solution
mega_destroyer
I'm currently looking at the documentation for xrandr and I think I may have a solution though I doubt it's permanent between reboots
mega_destroyer
I'll try to make a startup script with that xrandr command in it
mega_destroyer
I'll keep you updated
k9t33n
ok thanks
k9t33n
wait if it flips vertically can't you just flip it in real life vertically back? but keep it horizontal still
mega_destroyer
No, as it flips both vertically and horizontally, not asin rotation but mirrored
k9t33n
ah ok
mega_destroyer
dang nothing?
mega_destroyer
Any help appreciated
k9t33n
ok i got an idea tho
k9t33n
any script you run or vidoes you take etc, you just flip them
