I am running the latest version of Linux Mint 64 bit on a Asus K56CB-XX396H laptop (upgraded with a SAMSUNG SSD).
I have already changed the bluetooth discover command to be executed after my system has booted, instead of during boot, but that changes nothing. I removed the normal mint bluetooth manager in favor of Blueman, which worked better, but did not solve the issue.
After the crash occours, blueman (or other bluetooth managers) seem to flip out and become unresponsive. When i kill the bluetooth process, blueman errors into a "Connection Failed: blueman.bluez.errors.DBusFailedError: Software caused connection abort" error. afterwards the entire applet becomes unresponsive, and i can no longer find my bluetooth device in my list of active devices (which i think is logical)
Then i restart bluetooth with:
Code: Select all
sudo service bluetooth restartRestarting my pc fixes the issue, before it starts coming back again after a few minutes most of the time. Most answers i found while searching ask to do the same stuff i described above, but it clearly does not seem to work.
Do i have some sort of compatibillity issue with the bluetooth drivers? If yes, i do not mind running a command every once in a while to fix it, but i just can't find the command to make it work again.

Never mind. It fixed it once. The second time it happened blueman no longer shows up in the tray and i am unable to connect any bluetooth device until i restart.
