Start with the read-only checks:
hyperfluxctl status
hyperfluxctl doctorDoctor reports the first missing boundary, one safe action, and how to verify the result. It does not write hardware or restart services.
- Confirm Doctor reports the driver, bridge, and expected route healthy.
- Close the other device-control application so it releases its lease.
- Refresh or reopen the affected stock application once.
- If the route is unknown, sleeping, stale, or unqualified, leave it non-writable and include the Doctor summary in a support request.
Do not create a manual USB binding or register the receiver as a fake device.
The normal recovery is a reboot with the receiver connected. This preserves input on a receiver-only desktop.
Warning
Stop here unless a built-in keyboard and touchpad, a second keyboard and mouse, or a verified SSH session can recover the machine. Disconnecting the only affected receiver can remove all desktop input.
With alternate control already verified:
-
Close OpenRGB and Polychromatic.
-
Disconnect only the affected HyperFlux receiver.
-
Run:
sudo /usr/lib/hyperflux-next/hyperflux-next-activate activate-disconnected-driver
-
Reconnect only after the command reports matching installed and loaded identities.
-
If activation does not complete, leave the receiver connected and reboot normally. Do not force module removal or replace files under
/usr/src.
An older loaded OpenRazer route module still requires a normal reboot; the Core activation command does not reload OpenRazer modules.
Preview a support bundle before writing it:
hyperfluxctl support-bundle --previewThe preview performs no upload, active device query, or hardware write. Never post raw HID captures, hardware serials, private filesystem paths, or an unreviewed journal dump in a public issue.
Install a complete prior HyperFlux Core and Full package pair through the native
package manager, then reboot with the receiver connected. Mixing an ordinary
openrazer-driver-dkms package with the HyperFlux-transformed driver is not a
supported rollback.
