Bug Description

-- UPDATED DESCRIPTION --
If a user had the "Require encryption" set in intrepid and he upgraded to jaunty he couldn't set it back off without gconf-editor.

This is because the option is no longer there.

This makes it impossible in this case to connect to Vino using anything but Vinagre.
-- END UPDATED DESCRIPTION --

Binary package hint: vino

Dear friends,

I can't seem to connect to Vino using xvnc4viewer. Please look:

dawn@dawn-desktop:~$ xvnc4viewer -log *:stdout:100 localhost

When I try with grdc it gives me "Unknown authentication scheme from VNC server: -1215770256"

Seems I can't connect only when Vino encryption is set to require. Not sure what this encryption mean, maybe a special extension that only work between vinagre and vino?

Dear tinahouse,

You're right. That's the problem.

So there's a little bug here. I'm changing the description.

Many blessings.

Here is the workaround for this bug:

For those who are stuck in the same problem as me (encryption enabled in Gutsy/Intrepid, and cannot disable after Jaunty upgrade), here are the steps:

1. Open a Terminal (Applications -> Accessories -> Terminal)
2. Type gconf-editor and press Enter
3. Navigate in the tree pane of the Configuration Editor to:

/desktop/gnome/remote_access

4. Uncheck the "require_encryption" option.
5. Logout and log back in or restart.

That's it. Hope that helps somebody

The latest Grdc, now called Remmina, can connect to vino, even require_encryption is set to true.
