[Bug 883618] Re: Console upgrade useless.. XSet warnings all over the screen

[MMlosh]

Another reason why should the X11 messing thrown out:
Someone might have set his X11 to blank, say,  in 20 seconds (ie on open cellphone, not sure if GTA04 runs ubuntu, but it definitely could).
do-release-upgrade would then turn the screen off and on repeatedly.
Which is even worse with OLED displays, needlessly shortening their lives and wasting energy

So if polling is the best you can do, please don't do anything at all.

Title:
  Console upgrade useless.. XSet warnings all over the screen

Status in “update-manager” package in Ubuntu:
  Fix Committed

Bug description:
  Console upgrade via do-release-upgrade of kubuntu desktop is a real pain.  (from a Virtual Terminal, no X11 running)
  Unless you are watching every upgrade's move, there is no way to determine which question got asked.
  It gets scrolled away with  line this:  xset: Unable to open display ""
  also the line gets mis-aligned.

  I was not aware of the issue and watched >1h the screen filled with
  those  error messages..  While the upgrade process waited for my
  answer.
