OS: ubuntu 16.04 LTS
My laptop's bluetooth is winking in and out of existence, seemingly at random. I noticed at first when my bluetooth speakers turned off. Upon inspection the applet itself is disappearing, then reappearing in the top bar during these fits. They last for about ten seconds, then stabilize for a few minutes, then they wink in and out again.
I installed Blueman because some slightly similar issues were solved by it, but now I just have two applets that blink in and out at the same time, implying that there is some deeper issue.
