Switch to host desktop from citrix session
How can I leave the fullscreen mode of a citrix session and return to the host desktop (Ubuntu)?
I am using the Citrix Receiver for Linux package.
Two steps are needed for this.
Press ctrl+F2 in the citrix session. This enables keyboard shortcuts from the host system (Ubuntu).
Now you can use alt+tab to switch the focus to the application you used before opening citrix (or the desktop).
