The issue is that on Wayland when i use DRI_PRIME=1 to use dGPU for offloading
the screen goes black and never comes back on. On 4.20 the screen would go
black but would come back on after a second or two.

Will post logs later today.
And if i may ask whats the point of Xorg logs since this issue occurs ONLY in
Wayland ?
On Xorg the screen works perfectly fine and actually when using DRI_PRIME=1 the
display doesnt even go black for a sec.
The main issue with this bug is that when i turn on Wayland session of GNOME
the display would show my desktop but after few seconds it would go black and
then come back up. On 5.0 the screen goes black but never comes back up.
This makes it impossible to use Wayland session of GNOME.
