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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1824559 Title: Lenovo Yoga mouse is slow & laggy in bluetooth mode (low polling frequency) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1824559/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
