Comment 15 for bug 1724439

Well, my bug #1756036 just got (automatically-i-think) marked as a duplicate of this one, and I'm on 18.04 (gnome-shell 3.27.92-0ubuntu1) So that's one, Daniel. ;-) I'd been getting this on some mornings, but the bug report was getting rejected because of outdated packages until this morning. Interestingly it doesn't seem to happen again later in the day, so, as noted before, length-of-sleep may be a factor.

I reported a lot on these bugs in 17.10, until I eventually gave up and just used my (half-the-speed) mac for a while. Freshly-installed 18.04 and tried again, and I *am* having far less trouble. When it does go wrong, it "fails better", in that it seems to recover reasonably well and leave me with a working session, even if there are a couple of side-effects (eg: having both dash-to-dock and the dash in activities/applications) which clear on an orderly logout/login.
