https://bugzilla.kernel.org/show_bug.cgi?id=199461 --- Comment #8 from Maarten Fonville (maarten.fonville@xxxxxxxxx) --- @Michael the scroll wheel that stops working is not related to Bluetooth. I experienced the very same issue with the scroll wheel when using the mouse via USB. This happened since the upgrade to Ubuntu 19.04 and I think it is related to the desktop environment. It seems to be sometimes triggered by lock screen or suspend (but not 100% reproducible). Reconnecting the USB (or reconnecting via bluetooth) lets the desktop re-initialize the mouse and resolves the scroll wheel issue. -- You are receiving this mail because: You are the assignee for the bug.
