Public bug reported:
Dear maintainer,
Unl0kr doesn't take any input from a physical keyboard.
The device I'm using is a StarLabs StarLite Mk V (an x86_64 tablet that
ships with a Linux distribution by default) with the official keyboard
cover accessory.
Unl0kr is configured as a keyscript in /etc/crypttab to allow entering
the LUKS encryption password for the main drive.
(",keyscript=/usr/share/initramfs-tools/scripts/unl0kr-keyscript"
appended to /etc/crypttab)
So to reproduce, reboot, wait for unl0kr to prompt for the encryption
password and try to use a physical keyboard.
Expected behaviour:
- can use physical keyboard to enter the password
Actual behaviour:
- cannot use physical keyboard to enter the password (no characters appear)
The touchscreen works fine though.
Possible cause:
The initramfs hook script "/usr/share/initramfs-tools/hooks/unl0kr" doesn't
seem to properly copy "/usr/share/X11/xkb" to the initramfs, and thus some
keyboard stuff is not available to unl0kr.
Possible fix (that I've successfully been using):
Change the initramfs hook script "/usr/share/initramfs-tools/hooks/unl0kr" to
properly copy "/usr/share/X11/xkb".
The last line needs to be changed from:
cp -pPr /usr/share/X11/xkb ${DESTDIR}/usr/share/X11
to:
mkdir -p ${DESTDIR}/usr/share/X11/
cp -pPr /usr/share/X11/xkb ${DESTDIR}/usr/share/X11/
(Notice the trailing slash after "X11".)
Kind regards,
Simon Sievert
