No, it occurs with Gnome on Xorg, with modesetting driver. Gnome on Wayland
seems to handle suspend and resume fine (even on unpatched 4.19-rc3). Also, I
tried xf86-video-amdgpu. It works like Gnome on Wayland, but sometimes after
resume one display is limited to 800x600 resolution only (it's a 4k display).
Probably another different issue.
I expected modesetting driver to work though.
