GIMP f11 should go fullscreen but does not work

[corrado venturini]

Started GIMP from terminal I have the following messages:
corrado@corrado-HP-p4-cc-0813:~$ gimp
Gtk-Message: 18:00:17.419: Failed to load module "canberra-gtk-module"
Missing fast-path babl conversion detected, Implementing missing babl fast paths
accelerates GEGL, GIMP and other software using babl, warnings are printed on
first occurance of formats used where a conversion has to be synthesized
programmatically by babl based on format description

*WARNING* missing babl fast path(s): "R'G'B' double" to "CIE Lab double"
*WARNING* missing babl fast path(s): "cairo-ARGB32" to "R'G'B'A u8"

GIMP started single window mode, I hit f11 to go fullscreen but I see just a sign 'do not stop'
I opened the problem to gitlab:
https://gitlab.gnome.org/GNOME/gimp/issues/2138
and i was suggested to open this problem to Ubuntu.

Problem occurs also in multiple windows mode and also with GIMP 2.8.22 in Ubuntu 18.04 Bionic

[corrado venturini (corradoventu)]

I have done other tests, the problem seems gimp does not capture function keys, also with f1 I have the Ubuntu desktop guide while if from menu I select Help -> Help I have the GIMP user manual.

[corrado venturini (corradoventu)]

Changed title from 'GIMP single window f11 should go fullscreen but does not work' to
'GIMP f11 should go fullscreen but does not work'

[corrado venturini (corradoventu)]

Sorry, the problem comes from BIOS settings on my HP 250, the bios was set to capture function keys and not pass them to the application. Changed BIOS settings solved the problem.
Please close my stupid bug
