Log shows error: "debian /usr/libexec/gdm-wayland-session[4073]: Unsupported modifier, resource creation failed." repeatedly.
It looks as though this error message is coming from the Wayland session
that was run by gdm (which in this case seems to be sway) rather than
from gdm itself, so I'm reassigning this to sway to start with. It might
really be an issue in some lower-level component like wlroots or mesa.

Is this the only GPU in this system: the Intel HD Graphics 3000
integrated GPU that is built-in to a Sandy Bridge (Core 2xxx) CPU?

These messages from earlier in the session might also be relevant. They
occur several times in the log.

These messages start about an hour after boot in the provided log, and
continue, extremely frequently (many times per second), from that point.
They come from the crocus or iris driver for Intel GPUs, which is part of
Mesa (both drivers contain this message so I can't immediately tell
which one was active on this system).
