I'm uncertain if this channel is still open, but It seems that the problem has returned. I'm not quite sure why, I think it might be that I didn't properly update to boot parameters when I was testing kernel 5.3.0 - 994 but either way, it seems that the new kernel isn't a solution. On Tue, Sep 3,

I've tried both switching to Ubuntu on wayland and I installed kernel 5.3-rc3 and there hasn't been any change. I'm not sure what I'm supposed to be seeing in the terminal window when I run dmesg -w but here is a screenshot of part of the output. Nothing gets added to the output when the
