Worked fine before, but since upgrading to Ubuntu 14.04 LTS, whilst the connection shows in Finder OK when clicking on it says "Connection failed to “XXX's remote desktop on Xxxxx”. The software on the remote computer appears to be incompatible with this version of Screen Sharing."
Desktop Sharing Preferences set to allow sharing and a password is requeted.
Everything else seems OK. Anyone got any ideas?
Sorted.
Using a combination of clues from http://discourse.ubuntu.com/t/remote-desktop-sharing-in-ubuntu-14-04/1640 (which is all about VNC access) and https://bugs.launchpad.net/ubuntu/+source/vino/+bug/1281250 (which discusses the bug introduced into Vino) I have managed to resolve the matter.
Essentially you have to disable encryption on remote desktop access in Gnome due to a bug that has come to surface in Vino. However some threads tell you uncheck it in the wrong place. Follow these guidelines and you should be able to resolve it quickly.
Specifically it's
dconf > org > gnome > desktop > remote-access > require-encryption - uncheck
dconf > desktop > gnome > remote-access > enabled - uncheck
Here is how you do it:
Desktop Sharing is set up properly.dconf-tools by typing in Terminal sudo apt-get install dconf-toolsdconf-editororggnomedesktopremote-accessrequire-encryption (don't click on Set to Default as it rechecks it)It should now work. Tested through a reboot and all good.
Hope it helps.
(I have got a screen shot of dconf but don't have enough points on here to post it - I am sure everyone can work it out for themselves though! :-) )
From Raffi's comment and LinuxConfig.org. Tested on Ubuntu 18.04 and 20.04.
$ gsettings set org.gnome.Vino require-encryption false
then verify the setting with
$ gsettings list-recursively org.gnome.Vino | grep encrypt
