So I have to use MS Teams for working purposes. And yes, Teams has been working nicely recently on Ubuntu 20.04. Until yesterday, where I was sharing my screen through a Teams audio call and my whole system crashed. I mean: the operating system crashed. I could not even kill the process. Even if I would open a console (ctrl+alt+t) and sudo kill -9 for Teams, I would get no answer.

I tried even a sudo reboot now but nothing happended. The machine was stucked there, freezed; no response at all. In the end I hade to power-off/on the laptop with the power button.

So I know this is somehow a description of the situation but very weird in the end. As I have read in another post, Ha! Never know that an application running without root permission can crash you OS.

Well, I have these files under /var/crash:

lucas@lucas:/var/crash$ ll
total 325636
drwxrwsrwt  2 root     whoopsie      4096 feb 11 09:51 ./
drwxr-xr-x 14 root     root          4096 abr 23  2020 ../
-rw-r-----  1 lucas    whoopsie  47178713 feb 10 17:51 _usr_share_teams_teams.1000.crash
-rw-r--r--  1 lucas    whoopsie         0 feb 10 14:11 _usr_share_teams_teams.1000.upload
-rw-------  1 whoopsie whoopsie        37 feb 10 14:11 _usr_share_teams_teams.1000.uploaded

And I'm using Teams version :

lucas@lucas:/var/crash$ apt list teams
Listing... Done
teams/stable,now 1.3.00.30857 amd64 [installed]
N: There are 5 additional versions. Please use the '-a' switch to see them.

Has anyone experienced something like this before? Any hint or idea/suggestion?

Thanks.

I turned off GPU hardware acceleration in the Teams client settings and had no problems since. Teams also seems to use less CPU...

Teams 1.4.00.7556

I experience the same crash / freezing on my laptop showing two displays (built-in plus external monitor). I have learned I am able to recover by unplugging the additional monitor, and then teams became responsive after a few seconds. I typically then kill Teams and restart the app. To me, this could be a combination of GPU driver and Teams resource demands.

Teams v 1.4.00.7556 amd64 x11 Ubuntu 20.04
