I recently upgraded from Ubuntu 17.04 to 17.10, which came with the GNOME desktop environment. Overall, I have been pleased, but one thing that has been driving me crazy is the loss of "complete" keyboard capture in a remote session with the Citrix receiver. Before the upgrade, I could use keyboard shortcuts and largely avoid the mouse, switching back to the host when needed with ALT+F2. Now, even ALT+TAB doesn't work. (It switches me back to applications in the host Ubuntu desktop.)
To be clear, I can still type and whatnot in the client session, but hotkeys no longer work. I have tried adjusting the All Regions parameter in the Citrix .ini file, but to no avail. Any thoughts on how to resolve this would be amazing.
