This looks like a hardware problem or a kernel bug so reassigning...

Could you try downloading https://github.com/winterheart/broadcom-bt-firmware/blob/master/brcm/BCM20702A1-0a5c-21e8.hcd to your /lib/firmware/brcm folder and see if the issue persists?

[Kai-Heng Feng (kaihengfeng)]

Does touchpad or external have the same issue? Maybe the cursor isn't moving because graphics freezes?

[Daniel van Vugt (vanvugt)]

In Xorg sessions, the mouse cursor is managed by the Xorg process. So it won't be affected by graphics problems in the gnome-shell process at least.

So what i have done since is:
Downloaded and copied the firmware as advised by You-Sheng Yang (vicamo).
Rebooted and then tried again, time was slightly less in waiting.

I then removed blueman again just in case that was giving issues and reattached the mouse via bluetooth (reboot again) with the same result.

And on the issue with the touchpad, it works fine, i also disabled it via the bios and used a wired mouse and that works fine.

I'll be getting another wireless mouse to test tomorrow.

More info!

I checked the logs again and found:

xhci_hcd 0000:3e:00.0: HC died; cleaning up

Another one at the same time shows this message:

xhci_hcd 0000:3e:00.0: PCI post-resume error -19!

[You-Sheng Yang (vicamo)]

@Sam, please try following kernel boot parameters, reboot and attach output of `journalctl -b`:

  btusb.enable_autosuspend=0

For detailed steps, please see https://wiki.ubuntu.com/Kernel/KernelBootParameters#Temporarily_Add_a_Kernel_Boot_Parameter_for_Testing

[Sam Srzen (ssarzen)]

[Daniel van Vugt (vanvugt)]

If the affected laptop is dead then this bug is closed.
