Commen= t # 8 on bug 10851= 4 from Werner Lueckel 
more tests with flickering screen:

- check modelines "xvidtune -show -display :0"
  14.04 trusty (NO flickering)
  "1680x1050" 122.00 1680 1712 1776 1904 1050 1051 1054 1066 -hsy=
nc -vsync
  18.04.1 LTS (Flickering screen)
  "1680x1050" 122.00 1680 1712 1776 1904 1050 1051 1054 1066 -hsy=
nc -vsync
  -> exactly the same

- on 18.04.1 LTS=20
  (1) with flickering grafic screen:
  repeatedly switch the screen-mode (xrandr):=20
    to 1440x900 and back to 1680x1050
  -> typically after 2...5 repetitions the screen is o.k. and stops flic=
kering

  (2) BUT: when the screen awakes from "sleep" -> the flickeri=
ng starts again!
      switch to text-console (F1) -> flickers too!
      switch back to grafic (F7) -> flickering continues

   the I may continue with (1)=20
   OR (frustrated):=20
   BOOT 14.04 trusty; which still works fine; excellent grafic; never flick=
ers;
   ... and start working!

- BUT: what can I do when support for "14.04 trusty" ends?
