The laptop with Debian 8 Jessie and Gnome 3 has the following problem.

When the locked screen is turned off, it can be seen through it as the entire screen turns white and then turns dark again, and so with a period of a couple of seconds. Some kind of flickering of the extinct screen.

You can see something like this on any laptop manually, if you first open an empty notebook, and then use the key to turn off the screen backlight (it is necessary to have light in the room), and then do the same, but with an open terminal or any other dark page and compare view screens.

How can this be fixed?

  • The case may be in the gland, so it would be useful to write a model. Or add the output of the corresponding utilities. - user1056837
  • @ user1056837 on ubuntu was not like this, it is rather something with either Gnome 3 itself or its screen saver. - edem
  • Is it really easier to tweak than write a laptop model? - user1056837
