Title:
  Lenovo T420s requires nomodeset to boot Focal Fossa; missing video
  drivers?

Status in Ubuntu:
  New

Bug description:
  My question is at this link:
  https://askubuntu.com/questions/1226885/lenovo-t420s-requires-nomodeset-to-boot-focal-fossa-missing-video-drivers?noredirect=1#comment2063909_1226885
  =======================================================================

  I have had to uninstall Focal Fossa 20.04 (April 2020) and revert back
  to Ubuntu 19.10 on my Lenovo T420s because the laptop was stuck on
  purple screen upon `do-release-upgrade`

  I used `nomodeset` to boot the machine but there are no drivers for
  Lenovo T420s. Here is the result of  `lshw -c video`

  ```
    *-display

  Has anyone tried to install Ubuntu 20.04 yet? If so, did you run into the above issue?
