Interesting. I did not know about view-lossage.

<f1> c C-g just briefly displays "Quit" and exits minibuffer. When running
"emacs -nw -Q" from a terminal, the same key is described correctly as
keyboard-quit.

After trying to exit C-x C-f with C-g, nothing shows up in view-lossage.
When I hold C-g for a couple of seconds, focus goes back to the buffer as
expected and "C-g [abort-recursive-edit]" shows up in view-lossage.

When hitting C-g while inside a buffer, view-lossage displays "C-g
[keyboard-quit]" correctly, though, which I would not expect if Ubuntu kept
Emacs from receiving keyboard events correctly.
