Still an issue here on 18.04 ... Tried the PPA ppa:unity7maintainers/unity7-desktop by curiosity... but this is loaded with crippling bugs that render it unusable and does not have the desktop sharing icon anymore.
The workaround from comment number 11, from Zakhar (alainb06) worked for me: Direct link: https://bugs.launchpad.net/ubuntu/+source/unity-control- center/+bug/1741027/comments/11 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1741027 Title: Screen sharing panels abort using an non-existent vino gsettings key To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity-control-center/+bug/1741027/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
