A default Gnome install of either Fedora 25 or Fedora 24 (latest spin) Workstation, on a machine with a Radeon HD6320 (AMD G-series T56N) graphics chip running 1360x768@60Hz, has a display that most of the time is black on boot (reboot required -- hangs?), but occasionally completes booting with a display that all over shimmers with white noise, as seen in the following video: https://www.youtube.com/watch?v=dHW6kM4koQ0 The problem has been traced to this Linux kernel commit https://github.com/torvalds/linux/commit/ff0bd441bdfbfa09d05fdba9829a0401a46635c1 , made to fix Bug 95206. Xorg logs and xrandr output seem to indicate the the same modeline is selected after this commit is reversed, even though the boot and display problems no longer occur. The equivalent Red Hat bug is https://bugzilla.redhat.com/show_bug.cgi?id=1402293
