Hi all,
I’m on a Framework Laptop 16 (AMD 7840HS) running Ubuntu 24.04.2 and I’m struggling to get the HDMI expansion card working.
The HDMI expansion card is FRACCHBZ01-3 (3rd Gen)
I’ve been trying to connect to my Samsung TV through HDMI.
What I’ve tried:
- Plugging the HDMI card into expansion slots 1, 2, and 4 which are documented here as supporting external displays
- plugging it in with the HDMI cable already connected, and with the HDMI cable not connected
- Turning it off and on again
- A 3rd party USB-C to HDMI adapter in the same ports – this works!
Observable symptoms:
When the cable is connected to the TV, the HDMI card appears to disconnect from USB after 3-4 seconds, then it comes back, and the whole disconnect/reconnect loop goes on forever. Here’s an example of 2 cycles from /var/log/syslog:

This appears to be the same issue as described in this thread from 2023. That thread didn’t come to a final resolution.
Has anyone else run into this? Any solutions?
