Do you have any other hardware between computer & monitor? (Ie a KVM Switch?)
The other post about display ID jogged my memory that KVMs (etc) don’t pass through the data (sometimes?), so just wondering whether there’s another factor here…
Not sure how it would only trigger this on updates, but just building a complete picture of the issue.
That’s comforting to know.
I have kinda the opppsite: a machine that isn’t changing it’s hardware, but it hasn’t had updates in ~2 years (due to some issues with an AUR package back then…)
I wonder if it’ll upgrade…?
I’ve kept arch-keyring updating now & again… so it should work, but I know packages change dependencies so, it’ll be an interesting one (ie full backup first)
