Comment 39 for bug 1724583

I can confirm this also happens on my system.

Logging into Fedora 25 Gnome wayland session fails on Dell laptop with Intel Haswell CPU and discrete Radeon HD 8790M graphics.

This used to work fine on F24 w/ 4.7.x kernel.

Hardware name: Dell Inc. Latitude E6540/0725FP

Version-Release number of selected component (if applicable):

Name : kernel-core
Arch : x86_64
Epoch : 0
Version : 4.8.11
Release : 300.fc25

Name : gnome-shell
Arch : x86_64
Epoch : 0
Version : 3.22.2
Release : 2.fc25

Name : mutter
Arch : i686
Epoch : 0
Version : 3.22.2
Release : 3.fc25

I ended up disabling radeon kms mode setting by adding radeon.modeset=0 to grub. With this kernel configuration, I can now start Gnome Wayland session successfully
