Thank you for taking the time to report this bug and helping to make
Ubuntu better. It sounds like some part of the system has crashed. To
help us find the cause of the crash please follow these steps:
1. Look in /var/crash for crash files and if found run:
ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.
2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where
ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine.
Do you find any links to recent problems on that page? If so then please
send the links to us.
3. If step 2 also failed then apply the workaround from bug 994921,
reboot, reproduce the crash, and retry step 1.
Please take care to avoid attaching .crash files to bugs as we are
unable to process them as file attachments. It would also be a security
risk for yourself.

As i965_dri.so is part of the libgl-mesa-dri package I downgraded this
specific package from version 20.0.8-0ubuntu1~18.04.1 back to
19.2.8-0ubuntu0~18.04.3.
This solves the problem. So I suspect that the problem is in this
specific package.
