A core of the CPU always reloaded after restart

[Piotr]

When the computer is started or rebooted, a core of the CPU is always at least 90% loaded. When the Xorg process is terminated via the system monitor, everything is fine.
A complete new installation did not fix the problem either.

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. You reported this bug some time ago and there have been many changes in Ubuntu since that time.

Ubuntu 16.04 (xenial) reached end-of-life on April 29, 2021.

Do you still see a problem related to the one that you reported when using a currently supported version of Ubuntu? Please let us know if you do, and describe in detail the problems that you are experiencing, otherwise this report can be left to expire in approximately 60 days time.

Thank you for helping make Ubuntu better.
