Description Alan Jenkins 2015-12-30 12:34:40 UTC
Created attachment 1110493 [details] journalctl -ab after boot + a couple of screen flashes, with gdm debugging enabled Description of problem: With Wayland enabled, I don't get to see the login screen. It flickers between black and "no signal". Disabling Wayland fixes this. (Step-by-step instructions to disable Wayland here: https://www.maketecheasier.com/fix-wayland-gdm-issue-fedora/). This is an Intel NUC 5CPYH system - "Braswell" SoC. I assume it's unlikely to be a problem in Wayland specifically. But hopefully someone will triage / help me identify the component it should be filed against. [It would also be nice if "disable Wayland" was listed somewhere as a troubleshooting option; I didn't see that anywhere. Any suggestions who to talk to? Maybe the install guide is a good starting point as it has a very minimal troubleshooting section] Version-Release number of selected component (if applicable): kernel 4.2.8-300.fc23.x86_64 (also on 4.2.3-300) wayland 1.9.0-1.fc23 mesa 11.1.0-20151218.fc23 mesa-libGLU 9.0.0-9.fc23 gnome-session-wayland-session-220.127.116.11-2.fc23 gdm 3.18.2-1.fc23 How reproducible: always, just turn the box on and wait for gdm to start. Steps to Reproduce: 1. Buy NUC5CPYH 2. Install Fedora Workstation 23 3. Boot Actual results: I don't get to see the login screen. It flickers between black and "no signal". Disabling Wayland fixes this. Expected results: Lovely free software GUI appears when booting my Fedora install. Additional info: Even with the workaround I get a few kernel messages "*ERROR* timed out waiting for Punit DDR DVFS request"

"Blocks: WaylandRelated" suggested by wiki page on debugging Wayland.

This seems to have fixed itself, yay! Current versions - I guess only the kernel has changed: linux 4.3.3-300.fc23.x86_64 wayland 1.9.0-1.fc23.x86_64 mesa 11.1.0-2.20151218.fc23.x86_64 mesa-libGLU 9.0.0-9.fc23.x86_64 gnome-session-wayland-session-18.104.22.168-2.fc23.x86_64 gdm-3.18.2-1.fc23.x86_64 xorg-x11-server-Xwayland-1.18.0-2.fc23.x86_64
