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 ? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1824559 Title: Lenovo Yoga mouse is slow & laggy in bluetooth mode (low polling frequency) Status in linux package in Ubuntu: Incomplete Bug description: Hello, 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).
