I have a Dell E6520 personal laptop. It's old and I've had problems with the Nouveau and Nvidia GPU. With the update to Fedora 25 and Wayland, I started having more random lockups. I had disabled hardware video acceleration in Chrome, but that wasn't fixing the issue. I finally decided to lookup disabling Wayland and video acceleration.
To disable Wayland, edit /etc/gdm/custom.conf:
[daemon]
# Uncoment the line below to force the login screen to use Xorg
WaylandEnable=false
To disable nouveau acceleration, edit /etc/default/grub
GRUB_CMDLINE_LINUX="rhgb quiet nouveau.noaccel=1"
Run the grub2-mkconfig command:
sudo grub2-mkconfig --output="/boot/grub2/grub.cfg
