bug#65769:

[Hugo Buddelmeijer]

Ok, just one more update on the hardware issue: I 'resolved' it, and
maybe I can help others by commenting here.

Specifying i915.enable_guc=0 as a kernel parameter at boot will ensure
the kernel doesn't get 'wedged' and now sway works on the libre kernel
too. I get the blinking cursor again if I forget.

I tried adding the kernel parameter to the config like this:

            (sysctl-service-type config =>
                     (sysctl-configuration
                      (settings (append '(("i915.enable_guc" . "0"))
                                        %default-sysctl-settings))))

But that does not work, so I have to add the parameter at boot time.
Maybe I'll create a new issue for that.

So now I can go back to actually using sway, and fixing my power
management! And perhaps, if it becomes annoying enough, the creation
of the /run/user/<greeter id> directory...
