Title:
  Subiquity does not clear the screen when starting

Status in subiquity package in Ubuntu:
  New

Bug description:
  When the live-installer is run via a serial console the screen size is
  not detected correctly.

  During the installation we see a mixture of subiquity and whatever
  happened to be on the screen before (see appended screen shot).
  Please, clear the screen completely.

  The first incorrect output is when asking whether to use the graphical
  installer. So the clear screen must be done before that question.

  A complete clear screen is possible in C with:

  #define CSI "\x1b["
  printf(CSI "2J" CSI "1;1H");

  Best regards

  Heinrich
