Comment 17 for bug 1962036

I wonder whether my problem is this bug 1962036, or something else.
Problem while upgrading impish to jammy: screen showing just
background (no windows), moving/clicking mouse eliciting the
"wait" cursor momentarily.
Fixed by hard reset, boot to "recovery" console, and used:
  dpkg --configure -a
  apt dist-upgrade
  shutdown -r now
