Display issues on external monitors after update to F38

Hi everyone,

this is my graphic configuration on my laptop:
Device-1: NVIDIA GA104M [GeForce RTX 3070 Mobile / Max-Q]
Device-2: AMD Cezanne [Radeon Vega Series / Radeon Mobile

when i was on F37, i used "nouveau "driver with no issue.
After the update to F38, the display on main monitor was OK, but i had blank display on external monitors (i notice the same behaviour when booting on live ISO F38).
I think there is a problem with nouveau driver. Am I the only one ?

i install Nvidia drivers and no issue with external monitors. But i have another issue ( when i play a full screen mode vidéo, this message floods log file : “gnome-shell[2750]: meta_wayland_buffer_try_acquire_scanout: assertion ‘scanout’ failed” and my laptop reboots.

i would like to resolve blank display with nouveau drivers at first if possible. If not possible, try to understand the wayland problem with nvidia drivers.

Thanks in advance for your help.
