Weird. I have to switch all my machines to x11 in order to get multiple monitors working. Wayland just renders back screens on everything but main. Also makes remote desktop access buggy as fuck if it works at all.

Do you have another machine(or even a phone with an ssh tool like connectbot) you can use to try remoting into the machine while it is “frozen”? If you can still ssh in, that would indicate it is a DE issue, and you can poke around from there, try forcing a restart of the DE

If something breaks then roll back to the previous version?

I thought they already did this? Wasn’t that their justification for killing integrated SMS?
