FW 13 - Ryzen AI 9 - Thunderbolt/DP Display Output is Broken

My two thunderbolt 3 displays do not work in any of the 4 ports on the Framework 13 w/ AI 9 HX 370 CPU. When I plug in the thunderbolt cable, nothing on the external or internal display changes, I don’t see any extra displays in the GNOME Displays setting, and the only thing I see in the kernel messages is the following:

[ 1971.199794] ucsi_acpi USBC000:00: UCSI_GET_PDOS failed (-5)
[ 1972.107619] ucsi_acpi USBC000:00: unknown error 0

If I plug it into the bottom/nearest two ports, the monitors are enumerated as USB hubs and simple control devices, but nothing more.

These displays do work well with my Framework 16.

Anyone else hitting this? Any suggestions?


Which Linux distro and kernels have you tried?
I have tried all of the following:

  • Fedora 42 - Kernel 6.14
  • Debian testing/trixie/13 - Kernel 6.12.27
  • Debian testing/trixie/13 - Kernel 6.14 (from experimental)
  • Debian testing/trixie/13 with self-built kernel v6.15-rc7-142-g4856ebd99715

Which BIOS version are you using?
3.03

Which Framework Laptop 13 model are you using?
AMD Ryzenβ„’ AI 300 Series

What monitors are you using?

Do you have any output when you run boltctl list I had to authorize my thunderbolt dock via boltctl authorize <id>

Great idea! Unfortunately, boltctl list shows no devices. If I do boltctl list -a, it shows the two USB4 host interfaces, but they are already authorized.

boltctl list -a
boltctl list -a

I also tried using the displays on a fresh Windows 11 install (with the driver bundle). Nothing happened on Windows 11, when I plugged in the displays, either. So, maybe this is a hardware issue?

On Debian trixie with kernel 6.14, I see the following extra debug messages:

$ echo 'module thunderbolt +p' | sudo tee /sys/kernel/debug/dynamic_debug/control
$ echo 'module drm +p' | sudo tee /sys/kernel/debug/dynamic_debug/control

Trying New Cables

I have tried a bunch of brand new genuine certified thunderbolt 5 cables, even though my original setup/cables work perfectly fine on my Framework 16 and a ~2024 MacBook Air.

  1. Cable Matters [Intel Certified] 80Gbps Premium Braided Thunderbolt 5 Cable 1m

  2. Anker Prime Thunderbolt 5 Cable, 3.3 FT 80Gbps (Thunderbolt 5-Certified)

  3. Apple Thunderbolt 5 (USB‑C) Pro Cable (1m)

  4. My original cables are 2m long thunderbolt 3 cables, which came with the thunderbolt 3 LG Ultrafine 4K and 5K monitors. Again, these cables and monitors work perfectly with other computers, including the framework 16.


  • The 24" 4K LG UltraFine 24MD4K Display now works with all of the new thunderbolt 5 cables.

  • The 27" 5K LG UltraFine Display sometimes connects using the new cables, but when it does connect, GNOME crashes and send me back to the login screen. When I log back in, I can use the 5K display. This does not always work.

    When it doesn't connect, we see a bunch of these errors

  • When daisy chaining the monitors together, the 5K monitor appears in the display settings menu (although in portrait mode for some reason), but it remains black. If I adjust the settings, the laptop builtin display will hang indefinitely. This daisy chaining works with other computers, including the framework 16.
