I'm experiencing issues with my laptop's internal bluetooth adapter. It lost the connection to my wireless mouse a few times, and then lost the mouse entirely.

When I used sudo service bluetooth restart, it just disappeared entirely, and now no longer even appears in the system tray.

I'm not sure how to get it back so I can pair to other devices.

System Tray

EDIT 0: Also when I'm in the bluetooth GUI manager it says that my bluetooth adapter is not powered. I'll post more when I get back home. Not Powered

EDIT 1: Upon restarting, bluetooth works again, but it still has this strange stutter issue. My mouse is connected via bluetooth, but about every minute it seemingly loses the signal and I can move the mouse and nothing will happen on the screen. Then the mouse will move the way it was supposed to but with only after 5 seconds, sometimes longer. Then it's fine until it does it again in the next minute.

EDIT 2: Computer Information:

And I'm using an HP ENVY 17.

  • What does `uname -r` reveal in the kernel? – WinEunuuchs2Unix Apr 23 '19 at 01:51
  • @WinEunuuchs2Unix It's a fresh install, but I ran it anyway: `5.0.0-13-generic` – Sarah Szabo Apr 23 '19 at 03:58
  • Try an older kernel: https://askubuntu.com/questions/119080/how-to-update-kernel-to-the-latest-mainline-version-without-any-distro-upgrade/885165#885165 I can vouch for `4.14.110` but there are many to choose from. – WinEunuuchs2Unix Apr 23 '19 at 04:49
  • @WinEunuuchs2Unix That's a good point. I didn't think that the kernel upgrade might have done it. Is there something wrong with the kernel? Can I file something like a big report or is that just how it is? I'll try it later. – Sarah Szabo Apr 23 '19 at 20:06
  • All I can say is no problems for me with Kernel `4.14.110`. Try that version to see if things work. The other thing is we need to know your computer and wifi model numbers. – WinEunuuchs2Unix Apr 23 '19 at 21:43
  • @WinEunuuchs2Unix I posted the wi-fi/bluetooth card. I'm using kernel `4.15.18-041518-generic`. No problems yet, I'll test the Bluetooth later. – Sarah Szabo Apr 24 '19 at 00:16
  • I use infrared mouse and keyboard so don't have any problems. But here is a complicated answer that may help you: https://askubuntu.com/questions/1090149/bluetooth-mouse-lags-after-upgrading-to-18-10-cosmic – WinEunuuchs2Unix Apr 24 '19 at 01:49
  • Have you filled a launchpad bug for this? I've just ran into a very similar situation(Kubuntu 19.04, bluetooth mouse suddenly stopped working and the bluetooth adapter suddenly stopped being detected) and wouldn't want to duplicate reports. – Syfer Polski Sep 15 '19 at 14:38
