Using the Alpha 4 livecd with an updated libgtk-vnc connecting to tightvnc 3.3.tight1.2.9, I can confirm this bug. The problem appears to be one of gtk keyboard focus: while clicking on elements generally focuses them, clicking on the remote screen doesn't.
As a workaround, try clicking on the tab for the screen in order to place the focus there, and then press Tab in order to move the focus to the screen. After doing so, everything should work normally, including the Ctrl-Alt to grab the mouse, which doesn't work unless the screen is focused. I'll probably report this upstream rather soon, as it doesn't appear to have been noted there yet. The bug should probably be rather easy to fix. ** Changed in: vinagre (Ubuntu) Status: New => Confirmed -- Vinagre keyboard not working, mouse not always visible https://bugs.launchpad.net/bugs/192051 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
