[amdgpu] Fullscreen in any Wayland / Xwayland window shows a black screen (no screen detected)

[Noctis Bennington]

When I go into "fullscreen" watching a video while browsing in Firefox or when playing a game through Steam (fullscreen mode), the screen goes black.

The workaround I have discovered to get back is to enter the gdm from "Ctrl + alt + F1" and then return to the session you were in (normally, "Ctrl + alt + F2).

Edit: It happens when I connect a second monitor and use it as the primary display while the laptop screen is disabled.

I add here lspci-vnvn just in case.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This change was made by a bot.

[Noctis Bennington (noctis13)]

I just realised that this doesn't happen when you suspend the computer and then resume it.

[Noctis Bennington (noctis13)]

More info: In "Settings - Monitors" it shows like it's not connected to the second monitor when this happens. It is like it disconnects automatically from the system for some reason.

[Noctis Bennington (noctis13)]

I opened a report here in freedesktop:

https://gitlab.freedesktop.org/drm/amd/-/issues/2993#note_2172154

And as Michel Dänzer says, it's possible this is an issue related to Mutter. Here in these logs from journalctl gnome-shell I attach here, you can see the messages that appear just when, upon opening a game in fullscreen, the screen 'disconnects'.

[Noctis Bennington (noctis13)]

Here, there's an issue opened in Gitlab Gnome about mutter that could be related to this issue (thanks again to Michel Dänzer):
https://gitlab.gnome.org/GNOME/mutter/-/issues/3036

[Noctis Bennington (noctis13)]

Bug fixed with kernel 6.6.x, more info, please see here:

https://gitlab.gnome.org/GNOME/mutter/-/issues/3036

[Mario Limonciello (superm1)]

Is this happening possibly when there is a resolution change for the eDP? If so, can you please try the latest linux-6.5.y kernel: https://kernel.ubuntu.com/mainline/v6.5.13/

[Noctis Bennington (noctis13)]

No, this was an issue happening in monitors connected via HDMI.

[Mario Limonciello (superm1)]

OK thanks for clarifying. Can you please still try latest 6.5.13 and 6.6.6 and see if it happens in either of those?

[Noctis Bennington (noctis13)]

6.5.13 ----> "Test amd64/build failed (rc=2, on=amd64, time=0:07:36, log=amd64/log)".

@superm1

In 6.6.6 this issue seems fixed FYI.

[Mario Limonciello (superm1)]

Since the PPA failed would you be able to manually build 6.5.13 to see if it's fixed there?
