Bug Description

I have an issue with a lenovo yoga mouse.
This mouse has 2 working mode either bluetooth or with a provided usb dongle.
USB dongle works fine, but bluetooth don't.
Cursor is slow and laggy.
"evhz" (https://gitlab.com/iankelling/evhz) reports 22Hz in bluetooth mouse while USB mode and other mouse reports 125Hz.
Polling speed is too slow.

I tried different howto suggesting to change usbhid mousepoll value => does not help.
The mouse seems handled by btusb module, not usbhid (modprobe -r usbhid killed my other mouse, but not the lenovo, while modprobe -r btusb killed the lenovo).

I tried 2 laptops (XPS9370 with 18.04, kernel 4.18 and kernek 5.07 and an older dell Precision M6400 16.04 kernel 4.15).

Bluetooth pairing works well, either with gnome bluetooth interface or with "bluetoothctl"

Both laptops reports ~20-22Hz polling speed with evhz (and same laggy behavior)

I also tried 2 bluetooth interface on the XPS13 9370 : the integrated bluetooth and a Sabrent USB Bluetooth 4.0 (to connect with the Sabrent, I have switched off integrated bluetooth with rfkill).

Added bluetoothctl "info" output.

Thanks for the detailed bug report. I suspect the low polling frequency has more to do with the kernel than with bluez, so reassigning there.

That is, unless the problem is one of interference. Please try moving away from any strong 2.4GHz wifi access points and turning off other bluetooth devices. Please also try a non-Linux device if you can find one.

Please also try the Atheros kernel options mentioned in bug 1746164 (which is about Atheros wifi causing a low quality Bluetooth signal).

Hello Daniel,
Thank you for your answer!
OK for kernel assignment...to be honest, I was not sure where to assign it :)

Let me share last tests I did:
- upgrade to Bluez 5.50 (previously 5.48) (I added the bluez ppa and apt update / upgrade. then disconnect the mouse, re-pair it) => same situation.
- I paired with my work laptop (win7) : it works perfectly in Bluetooth.
- I tried different places (2 places at home, and now a third one at work) => works fine on my work laptop win7; not on my XPS with ubuntu.

I have read the bug 1746164 you mentioned, but:
- I tried 2 ubuntu laptop and my XPS13 9370 is based on ath10k (not ath9k) ? (I'm not sure for the other laptop). Is this bug applicable to ath10k ?
- I also tried a Sabrent bluetooth 4.0 usb stick...this one is based on CSR chip => issue is still there (with ~20Hz polling while it's 22Hz with internal bluetooth)
- I can still anyway try to check this issue from bug 1746164: do you think I can check it by turning OFF the wifi and test my mouse again ?

works for me

Following giors post #9 and a similar suggestion I get from a reddit user, I did the following:

sudo nano /var/lib/bluetooth/xx\:xx\:xx\:xx\:xx\:xx/yy\:yy\:yy\:yy\:yy\:yy/info

where xx:xx.... is pc bluetooth address and yy:yy... is the mouse bluetooth address.

In the file, I added the section at the end:


the value was proposed by this reddit user, I did not do any specific tuning.

then, I restarted bluetooth service with:
systemctl restart bluetooth

So far, it works! the mouse is fast and evhz gives this:

I have Ubuntu 18.04 on a Dell XPS 13 with a Logitech bluetooth mouse m720 triathlon with the same issue (20Hz polling rate by default). Following the steps given by wysiwyg31 in #10 (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1824559/comments/10) solved my issue.

With kernel 5.3.0-10-generic (the default on 19.10 beta image), I experience exactly the same issue as originally described. After updating to kernel 5.3.0-13-generic, the issue is gone and both mice cursors respond very smoothly.

The issue is gone.

@wysiwyg31: could you give it a try? You can boot a live session of Ubuntu 19.10 on your device and try to pair your Bluetooth mouse.

If it works for you, I'll mark the issue as Fix Released.

Hi @pieq, following your message I launched download of Ubuntu 19.10 image.
I will test with live session as suggested (as I keep my laptop on LTS for the moment)

Hi @pieq, juste tested with ubuntu 19.10 live session (I just paired the mouse with bluetooth GUI and moved the cursor around with the lenevo mouse).
The cursor is slow and laggy with the lenovo mouse (it's ok with trackpad).

Somewhat it seems not solved with ubuntu 19.10 for my mouse.

Hi, I migrate my laptop to Manjaro, but kernell 5.6.8-1 is still slow and laggy with the yoga mouse

Funny I was having this problem, or at least similar, and I found out the wifi was interfering. Moving the router away from the laptop resolved the issue.
