[Bug]: Enabling the NPU driver on the A311D caused the desktop environment to fail to start #9525
Description
What happened?
When using xfce4 on CAINIAO CNIoT-CORE (Amlogic A311D SoC), I found it impossible to enter the GUI; even lightdm fails to display.
The system is a self-built Armbian Ubuntu Noble with kernel version current 6.18.
I attempted to start the desktop directly using startxfce4, but the output log showed that the X server failed to start. I then checked the armbian/build source code and discovered that the file config/sources/families/include/meson64_common.inc was missing the Xorg configuration file specifically for CAINIAO CNIoT-CORE. After manually adding the /etc/X11/xorg.conf file, launching the X server via startx still failed, making me realize the problem might not be that simple.
The error log for startx is as follows:

The log shows that Xorg seemingly does not know which DRM device to use as the primary GPU, so it defaults to selecting etnaviv as the primary GPU and subsequently fails.
To verify if the issue was caused by the etnaviv NPU driver, I blacklisted etnaviv.ko, updated the initramfs, and rebooted the device. After this, startxfce4 was able to start the desktop.
Is there a way to use Xorg without disabling the NPU? I added an OutputClass section to /etc/X11/xorg.conf:
Section "OutputClass"
Identifier "Amlogic"
MatchDriver "meson"
Driver "modesetting"
Option "PrimaryGPU" "true"
EndSection
Then I re-enabled the NPU driver and rebooted the device. startxfce4 could then start the desktop. Below are the outputs of startx and cat /var/log/Xorg.0.log:

The issue where the etnaviv driver rendered Xorg unusable is now resolved. The PR for the fix is here, and I suspect this issue also exists on other A311D devices, such as the Khadas VIM3.
PS: I found online that etnaviv can seemingly be used for Xorg hardware acceleration, which requires modifying some configurations. However, I have not tested this, and it is currently outside the scope of this issue's discussion.

Regarding whether the etnaviv driver affects the Wayland environment, I also conducted tests by installing gnome/gdm. The results show that GNOME is also affected.
When blacklisting etnaviv:
GDM displays correctly and can enter the GNOME Wayland session.
When the etnaviv driver is enabled without setting the aforementioned OutputClass:
GDM does not display at all.
When the etnaviv driver is enabled and the aforementioned OutputClass is set:
GDM displays and can enter the GNOME session, but it is the Xorg version.
Attached are the journalctl /usr/bin/gnome-shell logs for the three scenarios mentioned above.
etnaviv-disabled.log
etnaviv-en-and-no-outputclass-set-in-xorg-conf.log
etnaviv-en-and-outputclass-set-in-xorg-conf.log
However, for Wayland environments like mutter/kwin_wayland, I do not have a perfect solution yet, so I am raising this issue here to seek help.
How to reproduce?
Just build xfce4 system image for A311D device
