Ok, so I restored my system and I got back to my Mate and all my settings are kept. I did a lot of things, even removed ecryptfs while extracted all my home directory from it. I removed NVidia drivers but I don't think that they caused the problem. But only reinstalling of XServer finally resolved the problem. I did something like described here: https://www.computersnyou.com/4945/re-install-xorg-xserver-completely-ubuntu/
Hint: if you get "Ubuntu Black Screen" then on GRUB item press "e" to edit menu item then replace "no splash" or "splash quit" with nomodeset and press F10. Thus I think the problem was caused by some tricky X11 configs upgrade. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1718658 Title: ecryptfs-mount-private fails to initialize ecryptfs keys To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ecryptfs-utils/+bug/1718658/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
