The patch works without problems (I didn't notice
the argument :force-onscreen before).

Saving the desktop in a GUI session and restoring in a TTY session
adds an empty line between the top buffer and the tab bar when
tab-bar-mode was enabled before saving.

Saving the desktop in a TTY session and restoring in a GUI session
restores only the first frame, but the message says 2 frames were restored.

I don't use a daemon session, maybe someone could help to test it.
