Previously, if `expected_node` couldn't import a buffer, it would print
an error, then try the next node. There shouldn't really be a reason to
attempt import if the format/modifier isn't in `dmabuf_texture_formats`.
It seems the issue I've been seeing with cosmic-workspaces crashing
the Nvidia driver is fixed by removing this, and disabling `dma_shadow_copy`
(which was producing the same error). Importing Nvidia buffers on the AMD
GPU seems to be causing issues.
Not sure how `dma_shadow_copy` should be fixed, but a test for supported
formats is easy to add here anyway.
Instead of choosing a primary GPU the first time `device_added` is
called (and then not updating it on the next call, even if that should
be the primary GPU), set the primary GPU only after all devices have
been initially added, and on future changes.
Alternately, the `was_empty` test can just be removed, but it's probably
best not to select the primary GPU multiple times each time the
compositor starts on a multi-GPU system.
Fixes https://github.com/pop-os/cosmic-comp/issues/1437.
Add more sophisticated code to handle the primary node disappearing.
Also overhaul the selection logic to respect our allow/deny-list and
prefer devices with built-in connectors before using the boot gpu.
This will also allow triggering a primary node switch at runtime
for debugging purposes in the future.
Not supressing key repetition in backends seems like it was a bug, and
should be fixed as of https://github.com/Smithay/smithay/pull/1535.
So an argument for this should be unnecessary now.
Previously, screenshots and screencopy panicked if no DRM render nodes
are present.
Instead, create a `GlowRenderer` using llvmpipe, if available. This
should work as a fallback until pixman is integrated.
