Mostly I don't understand this discussion and probably I should not take part in it. There has been no progress visible to me. The bug I reported was assigned as duplicate to this, so if this is now fixed, should I report the bug again?
Anyhow it appears to me, that to ordinary users sharing the PC, 18.04 is useless without changing back to lightdm (I hope that still works after latest development.) In practice that is not an option to most basic users, so going back to 16.04 or another distro is likely the choice. I am confused after reading all this development discussion. I would assume this is being fixed, but getting worried. ti 29. toukok. 2018 klo 5.05 Daniel van Vugt (daniel.van.v...@canonical.com) kirjoitti: > Marco, > > It sounds like you're talking about the secondary bug.
