I can't reproduce it, at least in QEMU (grub build for i386-pc).
Loading custom keyboard does change keyboard layout.

This bug is not clear, but I notice that at least in QEMU interrupt is
not disabled after startup and we never explicitly do it either. So
grub may race with BIOS for input characters. The commands mentioned in
this bug report (outb 0x64 0x60 ; outb 0x60 0x64) effectively disable
keyboard interrupt.
@Marco: would you be willing to test a patch that does it by default?

Well, you will need to debug this, as I said, I cannot reproduce it and
bug report you mentioned does not show any debug information either. If
you are willing to compile your grub, we could add debug output to
verify what you actually get from controller.

At last I executed grub-install and rebooted. This time I'm no longer able to boot : the screen is freezing at Grub's main menu, the timeout counter isn't even decreasing and I'm not able to enter into Grub's rescue. Removing the insmod line doesn't change anything.

To be sure - does it hang without at_keyboard as well? keylayouts is
loaded automatically as dependency of at_keyboard anyway, and it is
quite unlikely anything in this module would cause observed effect.

First try to reproduce it without GUI - it is rather hard to see
anything in this case. Just boot grub without any grub.cfg - you will be
left in plain CLI. Now try
insmod at_keyboard
terminal_input at_keyboard
does it still work? If yes, try keymap /grub/layout.gkb; does it still work?
and to be sure - could you send me your gkb file for test?

No it doesn't with only the keymap line (but the layout is still us).

Hangs right after this last command.

Sure you'll find it enclosed. Please also note that grub-kbdcomp is displaying the following warnings when creating the file :
Unknown keyboard scan code 0x54
Unknown keyboard scan code 0x65
Unknown keyboard scan code 0x7f
Thanks for your help.

Hello
After some tests on different boxes I found out that terminal_input at_keyboard does work well on some hardware :
- Dell laptop & tower : OK. Some keys doesn't respond (such as escape), but this may correspond to the "Unknown keyboard scan code" message
- Acer laptop : fails
- HP laptop : fails
So it may confirm a bios issue (please note that firmware is up-to-date on every box).
However I've also lost interest in this feature as my main usage was to be able to enter a LUKS password in my native language and unfortunately I found out despites that keymap works as intended on Dell computers, Grub2 still asks for password in us layout. AFAIU disk decryption is executed even before grub.cfg is read, so this might mean that the layout stuff has to be installed at early disk place.
