[Bug 1454450] Re: Bluetooth mouse laggy and erratic

Tue Jun 28 16:21:09 UTC 2016

Thank you for your work) 
The keyboard is http://www.samsung.com/us/support/owners/product/BKB-10USWEGXAR
Once it is paired it just becomes unstable. Big latency, and also Bbbuuuuugs liiike thisss. That particular bug is making it unusable. Also i was checking it in kacpimon, if acpi sees several key presses also, and it does. While that laggs there are no any errors at all in syslog or dmesg, only after disconnect. And it is not disconnected right after pairing. It is very random, but sometimes before error about disconnect drm:intel_pipe_update_end [i915] bug appears, sometimes not. Also important to mention that with windows 10 it works perfectcly (fast, stable, no disconnects). Every Bluez install i was installing with bluetooth library, but now i will try to work with native 5.37 lib and old and stable bluez to find if it is bluez or lib bug. A bit later i will give you my logs with buggy and with stable bluez. syslog with disconnect after intel error:
