It happens that after I original post this bug the frequency unreasonably decreased. But the problem is not solved with deactivated extensions.
Although I experience a suspicious behaviour on extensions removal. I'll describe it on the end. Re-description of the problem: After a 5min black screen enabled (less time more checks) and return. When If I have no apps open and no password, everything returns normally. If I have libreoffice (sometimes - I couldn't find the exact parameter) or xfburn working, then the fail returns. What I see a purple responding desktop but panels (topbar and dash) responds to mouse clicks. I have only suspend option on power options enabled (instead of settings,lock,power buttons). So, I just press ctrl+alt+f1, enter my password and the environment is restored but a little slower than normally. This could happen again, so again ctrl+alt+f1.. and so What if If I check on the options that I want my password to be asked, then everything is going well. Comment The reason I was late to answer is because the effect's frequency dropped so I couldn't find out if the deactivation of extensions was responsible or something else. Now I think that it was something else I could not figure out. Suspicious extension removal I tried to remove some extensions that I did not use anyway, so I tried to remove them through firefox and extensions.gnome page. Some of them I have to update them first and after that I have to remove them. But.. after I removed 5 or 6 of them, the removed ones re-appeared. So, I tried to remove them through software centre. It removed them and now it doesn't show them. But I still see them of gnome-tweak (which has similar behaviour with the site) and on the extensions.gnome site... and on my desktop activated. I press alt+f2 +r but they stayed. I rebooted and tried to removed them again in several ways, but always the same. So I just keep them deactivated. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1803527 Title: ubuntu 18.10 fails to restore from suspend if no password To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1803527/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
