Bug description

On Linux Mint 22.3 Cinnamon, using Cinnamon menu → Shut Down leaves my PC in a bad power state when openrazer-daemon is running.

The machine appears to shut down completely, but afterwards pressing the physical power button does nothing. I must unplug and reconnect the AC power cable before the machine can boot again.

The same machine shuts down and powers back on correctly when using:

sudo systemctl poweroff

or:

sudo shutdown -h now

The Cinnamon shutdown problem also disappears completely if openrazer-daemon.service is stopped or masked before shutdown.

I believe OpenRazer is likely the primary trigger, but I am reporting this here because the failure only occurs through the Cinnamon session shutdown path.

System information

• Linux Mint 22.3 Zena
• Cinnamon 6.6.9
• Kernel: 7.0.0-31-generic
• OpenRazer: 3.12.4~ubuntu24.04.1
• Mouse: Razer Basilisk V3 Pro 35K
• USB ID: 1532:00cd

Actual result:

The PC does not start until AC power is disconnected and reconnected.

A/B test

With OpenRazer running:

Cinnamon menu → Shut Down    FAIL
sudo systemctl poweroff      OK
sudo shutdown -h now         OK

If I first run:

systemctl --user stop openrazer-daemon.service

then:

Cinnamon menu → Shut Down    OK
sudo systemctl poweroff      OK
sudo shutdown -h now         OK

I have now masked the service:

systemctl --user mask --now openrazer-daemon.service

and Cinnamon shutdown works reliably again.

Relevant Cinnamon/systemd shutdown log

During the failed shutdown, Cinnamon correctly appears to request a systemd shutdown:

cinnamon-session-binary: Requesting system shutdown...
cinnamon-session-binary: Attempting to shutdown using systemd...
systemd-logind: The system will power off now!
systemd-logind: System is powering down.

The shutdown then continues all the way through:

systemd[1]: Reached target poweroff.target - System Power Off.
systemd[1]: Shutting down.
systemd-shutdown[1]: Syncing filesystems and block devices.
systemd-shutdown[1]: Sending SIGTERM to remaining processes...

So the Cinnamon shutdown request itself appears successful.

Relevant OpenRazer behavior

While openrazer-daemon is active, the kernel repeatedly reports:

razermouse: Command timed out. status: 04
transaction_id.id: 1f
command_class: 07
command_id.id: 80

During Cinnamon shutdown, the user OpenRazer service also sometimes exits with:

openrazer-daemon.service: Main process exited, code=exited, status=1/FAILURE
openrazer-daemon.service: Failed with result 'exit-code'.

When the OpenRazer daemon is masked, those repeated timeout messages disappear and Cinnamon shutdown works normally.

Steps to reproduce

With openrazer-daemon.service running:

1. Boot Linux Mint and log into Cinnamon.
2. Use Cinnamon menu → Shut Down.
3. The system visually powers off.
4. Press the physical PC power button.

Expected behavior

The machine should power off into a normal state where the physical power button can start it again.

Additional information

This PC previously had a separate firmware-related shutdown problem, which was fixed by updating the BIOS.

The current issue appeared again after installing/using the Razer mouse with OpenRazer and is reproducibly controlled by whether openrazer-daemon is running.

The OpenRazer kernel module can remain installed. Disabling only the userspace daemon is sufficient to eliminate the shutdown problem.

I am also reporting this to the OpenRazer project https://github.com/openrazer/openrazer/issues/2907.

Please let me know if additional Cinnamon session logs or a comparison trace between Cinnamon shutdown and systemctl poweroff would be useful.

The report names no source file or test; start at the Cinnamon session manager's systemd shutdown path and reproduce the A/B comparison with openrazer-daemon.service running versus masked. Compare the reported Cinnamon, systemd-logind, and OpenRazer behavior, with done meaning the shutdown path reliably leaves the machine restartable.
