Shutdown is so slow in16.04 – Ask Ubuntu

ccpd = Canon Printer Daemon for CUPS

On a system with Linux MINT 18 (based on Ubuntu 16.4 LTS) and a Canon LBP7210C network printer, I did this for a faster timeout to take precedence.

Edit the override.conf file

$ sudo systemctl edit ccpd.service

and enter

[Service]
TimeoutStopSec=10

to set the timeout to 10 seconds. Save and exit.
This change will prevail between each shutdown.

To check the modified timeout value, run

$ systemctl show ccpd.service -p TimeoutStopUSec
TimeoutStopUSec=10s

The same method was used in this post https://askubuntu.com/a/810237 for a different service.

Note: Each service has a timeout and its there for a reason. Changing the timeout for a network printer seems OK. For other services (eg: disk drives) the effect of changing a preset value must be carefully considered.

In MS Teams for linux, microphone stopped working

I had the same problem. Here is how I solved this:
If not already installed, install the PulseAudio volume control tool (sudo apt install pavucontrol)
Then, while Microsoft Team is running, open the “PulseAudio volume control” application.
Go in the Recording tab: you should see a mic volume slider for “Skype” (The Skype engine is probably used in Microsoft Team).
(If you don’t see “Skype”, be sure “Applications” is selected in the dropdown at the bottom of the Recording tag.)
Move the slider just a little to the right or to the left.
Then redo a Call Test in Teams. Now it should work.
After that, you can put back the slider exactly where it was, at 100% (0dB) and close the PulseAudio tool.
