Something similar happens with my bluetooth dongle; I need to stop the |
| 6 |
service, unload the kernel module, load it again, and start the |
| 7 |
service once more. |

Others have already gave you answers. I do not believe you use |
| 14 |
systemd; but for whomever else that does, I leave this here: systemd |
| 15 |
has a set of directories (one for sleep, another for hibernate, and a |
| 16 |
third one for "hybrid" modes), where you can drop any executable you |
| 17 |
want to be executed in any of those situations. From [1]: |
| 18 |
|
| 19 |
""" |
| 20 |
Immediately before entering system suspend and/or hibernation |
| 21 |
systemd-suspend.service (and the other mentioned units, respectively) |
| 22 |
will run all executables in /usr/lib/systemd/system-sleep/ and pass |
| 23 |
two arguments to them. The first argument will be "pre", the second |
| 24 |
either "suspend", "hibernate", or "hybrid-sleep" depending on the |
| 25 |
chosen action. Immediately after leaving system suspend and/or |
| 26 |
hibernation the same executables are run, but the first argument is |
| 27 |
now "post". All executables in this directory are executed in |
| 28 |
parallel, and execution of the action is not continued until all |
| 29 |
executables have finished. |

My bluetooth problem gets fixed with a little executable script in |
| 33 |
/usr/lib/systemd/system-sleep: |
| 34 |
|
| 35 |
#!/bin/bash |
| 36 |
|
| 37 |
case "$1" in |
| 38 |
"post") |
| 39 |
sleep 3 |
| 40 |
systemctl stop bluetooth.service |
| 41 |
rmmod rfcomm |
| 42 |
rmmod bnep |
| 43 |
rmmod btusb |
| 44 |
rmmod bluetooth |
| 45 |
modprobe bluetooth |
| 46 |
modprobe btusb |
| 47 |
modprobe bnep |
| 48 |
modprobe rfcomm |
| 49 |
systemctl start bluetooth.service |
