Today I updated ubuntu (usual update, that shows authomaticaly every few days) and after restarting, I got weird resolution (smaller screen), no internet connection, almost no options in settings menu,…
I don't know what happened an how to get things back?
Maybe this was somehow connected: after update and befor restarting I changed kernel from 4.15.0-43-generic to 4.15.0-45-generic (see this thread: Minecraft crashes, losing connection )
UPDATE: it also doesn't wake up from hybernation
Ifconfig -a gives me just lo interface. I don't get my ethernet
