<pre>have the monitor mentioned above and a new Intel NUC7i7BNH with 16 GB Ram and
128 GB SSD. Running Fedora 27 with the latest patches.
I'm using a USB -C cable to Display Port, and the screen will occasionally
flicker on and off and also display a gray bar across the screen
I have verified that there is no problem with the monitor or cable, this
problem does not exist using a Dell laptop with Window 10 and have also ran
through all diagnostics with a Dell technician. In addition the NUC has been
updated to the latest BIOS.
When I switch to 30hz there is no problem, is there a way to get the latest
Intel graphics drivers.
As a side and possibly note GNOME crashes every time a log in from a locked
session. I have submitted many bugs and it appears that others are having the
same problem.
Additionally I just install windows 10 on another drive (same Intel NUC). It
had the same problem with flickering. I updated the "Intel Iris Plus Graphics
650" driver to the latest version 2/4/2018 23.20.16.4944 and the problem has
been eliminated.
I checked Fedora 28 4/4/2018 beta and have the same problem.
