Do your backlight keys work?  E24 has introduced additional screen dimming, and
it will dim the backlight fully.  Maybe there's a strange interaction between
your video card's brightness control and E's behavior.

It's possible to disable this, but it'll be hard without ever getting an E
session going.  To try disabling by hand:

1) apt install libeet-bin
2) vieet ~/.e/e/config/standard/e_comp.cfg config
3) Search for "nofade"
4) Change the value from 0 to 1.  The line should be: 
    value "nofade" uchar: 1;

According to the info included in your bug report, your apt prefers testing and
has the expected versions of E & EFL from testing.  That all seems pretty
normal.  So I don't expect reinstalling anything will help.
