Why doesn't Remmina handle sending Alt-Tab to remote computer on 22.04 Jammy Jellyfish?

Question

Background

Two days ago I installed 22.04 Jammy Jellyfish as a complete clean install.
I was previously running 21.04 & a different version of Remmina. That version of Remmina on 21.04 would allow me to send a Ctrl-Tab (cycle through running apps) on remote Win10 desktop.

Main Problem

I began using Remmina (as I did in the past on 21.04) and discovered that I am completely unable to send Ctrl-Tab to the remote Windows 10 computer. This worked with no problem on Remmina running on 21.04.

I'm running Remmina version 1.4.27+ppa202206201051.r3b9cc80f8.d84ef65add~ubuntu22.04.1 on 22.04.

What I've Tried

I have selected the "capture keyboard" item in Remmina. You can see it is selected in the following image.

After selecting that item I received a very confusing warning about inhibiting system keyboard shortcuts.

I found the setting in Settings...Applications...Remmina but I'm still confused about what it means.

I've turned that setting on & off and tried sending Alt-Tab to the remote computer and it doesn't work either way.

Tried Other Keyboard Actions

I've tried and successfully run other keyboard actions. For example, I have shortcut on the remote Win10 Desktop that is set up to run when I do a Ctrl-Shift-RtArrow => and running the command does indeed work from Remmina.

However, I still can't seem to send a Ctrl-Tab (cycle through running tasks) on remote.

I've also tried installing older version of Remmina but that was difficult & didn't seem to work.

Other Answers : Old - Doesn't Work

I found this seemingly related question/answer here, but the solution is for older versions and doesn't seem to work.

Solution?

Does anyone know a solution so that I can send Ctrl-Tab to remote computer?

Answer 1

Workaround Solution

I needed a way to navigate away from a full-screen app running on the remote Win10 computer -- normally Alt-Tab (cycle through apps) would allow this.

I discovered that this version of Remmina will allow Ctrl-Esc (activate Win10 Start button - which also reveals the taskbar) to be sent to remote computer.

This is a valid workaround for my problem, but it would still be interesting to know why Ctrl-Tab doesn't work.

It is probably more related to Gnome than anything.
I'm running Gnome 42.2 under Ubuntu 22.04.

UPDATE - Definitive Answer

I was attempting to resolve another problem on 22.04 and I moved my window manager from Wayland to Xorg -- see that problem / resolution here.

After I made the change to Xorg (from wayland), I can now successfully send the ALT-TAB combination in Remmina to my remote desktop (win10). Everything works now that I've moved away from wayland.

Use X11 not Wayland.
