When I press f for a few seconds on one of the Trisquel installations on my
laptop (as usual made by debootstrapping and continuing from there), I expect
to get
ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff.
This is what I get upon login.
But if the screen blanks (i.e. because I close it) and I use the computer
after that, if I press f I only get f.
I've got Trisquel 6 on which LXDE, Lightdm, XFCE4 Power Manager, Compton but
not xscreensaver are used.
On the same laptop, there's a Trisquel 7 and Parabola installation as well
that don't seem to have the same problem I've described above.
Any ideas? (xset -r off didn't work, neither did setting).
