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
