The log says that I was using Ubuntu 21.04:

  • I’ve installed 20.04 after I’ve upgraded to 21.10:
    • I hated the new GNOME horizontal workspaces.
    • I had some problem with installing MySQL with 21.10, because it was too new at that time. This makes me think that I should have another log from 20.04 installation, but I don’t find it.

The great beginning of this log is:

“After the reboot after the install GNOME was stuck except for the top bar, another reboot fixed it.”

I have a GTX1060 6GB so maybe it was Nouveau’s drivers fault. I recommend if you have an Nvidia graphics card to install their proprietary drivers asap. Not hating on Nouveau: Nvidia is not collaborating that much for an open source driver.

If you want a good and open source driver use AMD Radeon GPUs or Intel IGPs.
