When connecting with Horizon Client for Linux (I tried 4.6.0 and later) to a Windows desktop, neither Ctrl-Alt-Del key combination nor the menu option "Send Ctrl-Alt-Del" have any effect. When the remote desktop locks, I have to disconnect and reconnect to unlock it. Why is it not working? Is there a setting I can change client-side? I tried:
view.sendCtrlAltDelToVM="TRUE"
in ~/.vmware/config, but there's no effect, either.
