Hyperion vs. GIMX on Raspberry Pi

Post by mav2010 »

Hi all,

I have a weird issue running GIMX on a Raspberry Pi with a Logitech G920, connected to a PS4.

Let me start by saying that running only GIMX on either a Raspberry Pi 4 or Zero W works wonderful. So I am not per se plagued by the known USB lag issues.

However, I am trying to run Hyperion (basically a custom built Ambilight) on the same Pi. The TV picture is channeled into the Pi by a USB Video grabber. Again: running Hyperian by itself - no issue. The moment I run both, the key presses become a bit random (sometimes key presses are swallowed, sometimes randon key presses are added) and force feedback is basically completely gone. The second I stop Hyperian, the force feedback works again and it even repeats the last few seconds of missing feedback, as if it was stuck somehwere.

I have tried on my Pi 4 and on my Pi Zero W various operating systems (mainly bullseye and buster based) and various Hyperian and GIMX versions. It appears to be a conflict between GIMX and the V4L2 driver that Hyperian is using for the USB grabber.

Any idea how to tackle this? I could really need a nudge in the right direction?

Thanks a lot!

I can actually (kind of) answer my own question. I borrowed a Raspberry Pi 2B and to my surprise the Hyperion / GIMX combination immediately worked! So now I understand why the RPi support is considered experimental…

So whatever causes the issue, it apparently only affects the Zero W and the Pi4, not the 2B… 😳

Nice investigating :D

You might have helped others from the headache with that.

The Hyperion / GIMX combination? I didn't expect it to work.

Randolph Moran,
Hyperion/GIMX combination worked right out of the box.
