Questions[vinagre](ubuntu)

I am using Ubuntu 20.04.1 on my local machine to connect to a remote desktop which also Ubuntu 20.04.1 (server). The remote server was converted to a "desktop" using apt install ubuntu-desktop and then XRDP was installed using apt install xrdp. For the configuration of XRDP, roughly the information given at https://help.ubuntu.com/community/xrdp was used. I am using Vinagre on the local machine to connect to the remote desktop.

A installed also the Dash to Panel extension on the desktop user of the remote server. However, this extension has a bug: When a click on the "Show Applications" button (the button with nine white dots) and try to do a "Search", the gnome-shell process for that user starts to use 100% CPU and the desktop becomes unresponsive. The solution is to kill this process. However, an easier method would be to press Alt+F2 and enter r in the command input box.

However, I am not able to enter Alt+F2 on the remote desktop even when Viagre is in full screen: The key combination is processed by the local machine.

How can I send Alt+F2 to the remote desktop in Viagre?

How do I clear the items in Vinagre under Remote > Recent Connections?

I've done this and it does not work. I've deleted the entire Vinagre profile directory ~/.local/share/vinagre and it somehow regenerates the recent connections list. I uninstalled and reinstall Vinagre... still there!

Where the heck is this stubborn list stored that I can actually delete it?

There is SPICE in vinagre for Fedora, but in the same version of vinagre in Ubuntu there is no SPICE. Why?

I am trying to use the Remote Desktop Viewer on my laptop to connect to my desktop, which I have configured with Remote Desktop preferences. But it fails to update the screen shot image, making it useless.

What can I do to speed it up and actually have usable Remote Desktop?

Any applications I can install on either/both sides to do it?
