Steps to reproduce: 1. Start the native ThinLinc client 2. Open the Options and change the "Popup menu key" to 'None' 3. Login to a server 4. Observe that the hint at the top of the screen says: "Press to open the context menu" We shouldn't display this hint if there isn't a key bound to it.
Since this was such a small fix I bypassed the vendordrop routine and committed directly to ThinLinc. Upstream PR here: https://github.com/TigerVNC/tigervnc/pull/894 Built and tested on Fedora 30.
Looks good. Got a confusing hint in the previous version with "None" configured, but nothing at all now. Also verified that that a properly configured menu key still gets the hint.
