I installed these releases today :

libdrm-intel1:amd64        2.4.75+git1702281830.5ee9cb~gd~x
libdrm-intel1:i386         2.4.75+git1702281830.5ee9cb~gd~x 
xserver-xorg-video-intel   2:2.99.917+git1703010733.78d7a0~gd~x

Thanks to the oibaf PPA on ubuntu 16.04.

Still no changes ... still issues with screens connected to my Dell E-Series
dock.
Screens are very long to light up sometimes (generaly, one is up and running
pretty fast but the second can take 10+ seconds to light up after the first one
is up).
Going out from blanked screen (when leaving my computer idle for a while for
example), one screen is ok but the second one flicker once in a while and it
takes much longer to light up, sometimes it gets back to power save before
returning live again.

Still same solution when it's doing this : I go to a TTY with ctrl+alt+F5 then
I return to my X session with ctrl+alt+F7 ... most of the times, it fixes the
issue, sometimes I have to do this 2-3 times.

It is not blocking since there is this workaround but it is very annoying.
