Missing python-openrazer dependency causes "No device" even when daemon detects Tartarus Pro

[Roel216]

I ran into an issue where OpenTartarus showed "No device" even though openrazer-daemon was running and correctly detecting my device.

System:

CachyOS (Arch-based)

Razer Tartarus Pro

OpenRazer daemon 3.12.2

The daemon output showed:

Found device.0: 0003:1532:0244.0006
Initialising device.0 RazerTartarusPro
Serving DBus

I had already:

started openrazer-daemon

confirmed my user was in the input group

restarted OpenTartarus

The issue was that the Python OpenRazer module was not installed:

ModuleNotFoundError: No module named 'openrazer'

Installing the Arch package:

python-openrazer

fixed the issue and OpenTartarus detected the device.

It may be worth mentioning python-openrazer as a dependency or adding a troubleshooting step for missing Python bindings.

Ran into this on Bazzite with a Razer Tartarus Pro, and my issue ended up being a combination of two separate problems.

Initially, nothing detected the keypad because the stable Bazzite image was shipping an older OpenRazer kernel module that didn't support the Tartarus Pro properly. Rebasing to the testing image fixed that part—after rebooting, OpenRazer and RazerGenie both detected the device correctly.

However, OpenTartarus still showed "No device."

It turned out I was also missing the Python OpenRazer bindings. Running:

python3 -c "from openrazer.client import DeviceManager"

gave:

ModuleNotFoundError: No module named 'openrazer'

Installing the missing package fixed it:

sudo rpm-ostree install python3-openrazer

After rebooting, the import worked:

python3 -c "from openrazer.client import DeviceManager"

and OpenTartarus immediately detected my Tartarus Pro.

So if anyone on Fedora/Bazzite ends up here:

• Make sure OpenRazer itself can already detect the device (openrazer-daemon/RazerGenie).
• Then check whether python3-openrazer is actually installed by running the import above.

In my case, that was the final missing piece.
