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 -hsync -vsync
18.04.1 LTS (Flickering screen)
"1680x1050" 122.00 1680 1712 1776 1904 1050 1051 1054 1066 -hsync -vsync
-> exactly the same
- on 18.04.1 LTS
(1) with flickering grafic screen:
repeatedly switch the screen-mode (xrandr):
to 1440x900 and back to 1680x1050
-> typically after 2...5 repetitions the screen is o.k. and stops flickering
(2) BUT: when the screen awakes from "sleep" -> the flickering starts again!
switch to text-console (F1) -> flickers too!
switch back to grafic (F7) -> flickering continues
the I may continue with (1)
OR (frustrated):
BOOT 14.04 trusty; which still works fine; excellent grafic; never flickers;
... and start working!
- BUT: what can I do when support for "14.04 trusty" ends?
