Problema com pop!_os 21.10

To fix this issue, all you need to do is to:

  • boot with nomodeset (or ssh into the machine)
  • enable the non-free repository, by editing /etc/apt/sources.list and adding contrib non-free after the main that’s on some of the lines there already
  • run apt-get update
  • install the firmware-amd-graphics package, which will now be pulled from non-free.
  • reboot, this time without the nomodeset, to activate the firmware.
