Bug#1083019: gtk4 apps crash when using vulkan renderer with Nvidia hybrid graphics drivers

[John M.]

Hi Jeremy. Thanks for the reply.

I'm not sure the issue is directly related
to https://launchpad.net/bugs/2081291 . Both baobab and gnome-system-
monitor (which, I believe, are gtk4-based) load without issue. 

I upgraded libgtk-4-1 to the version in unstable, which caused these
other updates as a side-effect:

# apt-show-versions | grep unstable | grep gtk
gir1.2-gtk-4.0:amd64/unstable 4.16.2+ds-3 uptodate
gtk-update-icon-cache:amd64/unstable 4.16.2+ds-3 uptodate
libgtk-4-1:amd64/unstable 4.16.2+ds-3 uptodate
libgtk-4-bin:amd64/unstable 4.16.2+ds-3 uptodate
libgtk-4-common:all/unstable 4.16.2+ds-3 uptodate
libgtk-4-dev:amd64/unstable 4.16.2+ds-3 uptodate
libgtk-4-media-gstreamer:amd64/unstable 4.16.2+ds-3 uptodate

After reboot, the situation is the same: nautilus doesn't load, but
baobab, gnome-system-monitor, etc., do load.

And, just to clarify: I'm using the NVIDIA GPU as the primary one (as
per these
instructions: https://wiki.debian.org/NVIDIA%20Optimus#Using_NVIDIA_GPU_as_the_primary_GPU
 ).
