Bug ID: 498964
Summary: LUKS password input freezes when unlocking multiple
drives
Classification: I don't know
Product: kde
Version: unspecified
Platform: Kubuntu
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: unassigned-b...@kde.org
Reporter: cmcgl...@protonmail.com
Target Milestone: ---
SUMMARY
I have recently installed Kubuntu 24.04 and set it up such that I have 2
separate physical drives encrypted. One drive has my root partition encrypted
but my /boot and /boot/efi are not encrypted. The other is my /home partition
which is encrypted all using LUKS2. When I boot the PC and get to the point
where I need to unlock the drives The first to request the unlock is the root
partition. When that is unlock the screen resizes to the correct monitor
resolution and, since I have 2 monitors, the other monitor is active. These
monitors are identical. The home partition is next to get unlocked as the
monitors are re-configuring and this is the problem. If I do not put in the
password fast enough then I cannot use my keyboard to type in the password
input screen. The password has to be before the monitors set themselves up. The
keyboard still works, I can ctrl-alt-delete to restart the PC, but I can't put
in my password to unlock the second drive no matter what I do. I don't know if
it has crashed or not but I can boot normally only if I put in the password
fast enough.
STEPS TO REPRODUCE
1. Set up a system (Kubuntu 24.04) with an encrypted root and home partition
which are on separate drives.
2. Use dual monitors with a resolution of 3840X2160.
3. Try to boot and unlock both drives.
OBSERVED RESULT
When the screen is resized after the root partition is unlocked the input to
unlock the second partition is disabled and you cannot continue to boot.
EXPECTED RESULT
I expect to be able to type in the password to unlock the second partition even
after the screen is resized automatically.

ADDITIONAL INFORMATION
I think the problem happens when the monitors are detected and resized. The
focus is no longer on the LUKS input and I don't know how to get it back to
being on the LUKS input.
