descending3rds, could you please test the latest upstream kernel
available from the very top line at the top of the page (the release
names are irrelevant for testing, and please do not test the daily
folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will
allow additional upstream developers to examine the issue.
If the test did not allow you to test to the issue (ex. you couldn't boot into
the OS) please make a comment in your report about this, and continue to test
the next most recent kernel version until you can test to the issue. Once
you've tested the upstream kernel, please comment on which kernel version
specifically you tested. If this bug is fixed in the mainline kernel, please
add the following tags by clicking on the yellow circle with a black pencil
icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-3.XY-rcZ
Where XY and Z are numbers corresponding to the kernel version.
If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-3.XY-rcZ
Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results.
Thank you for your understanding.

Title:
Keyboard does not respond/scrambled video
Status in linux package in Ubuntu:
Incomplete
Bug description:
Description: Ubuntu 14.04.2 LTS
Release: 14.04
Kernel 3.13.0-48-generic
I expected to be apple to boot to the password prompt for my encrypted root
(and beyond) with correct graphics.
Instead I found that my keyboard was not recognised after grub, so I am not
able to decrypt my root or login
More detailed explanation:
I have Ubuntu installed on my 17'' core-duo intel imac, with an encrypted
root partition.
Version 12.04 with kernel 3.5.0-17-generic worked ok, but I updated to the
LTS version 14.04.
The system now freezes before asking for my encryption password when booting
(I am using EFI with grub2)
with my old kernel (3.5.0-17-generic) and with no args on the kernel command
line. If I put nomodeset the boot
progresses to the encryption password and I can successfully login, however
the video is completely scrambled (I literally cannot
make out anything). Having tried many ways to fix the video, I tried the
latest kernel (3.13.0-48-generic). In this case
the boot gets to the password and the graphics appear to be ok, but the
keyboard/mouse do not respond. Again I tried many fixes, unsuccesfully. I
installed the extras so as to have usbhid, mac_hid etc, and found that the
behaviour now reverted precisely to that outlined above for 3.5.0-17-generic;
that is scrambled graphics but successful login (with nomodeset), and freezing
before
reaching the password prompt (without nomodeset).
I tried manually adding only the hid modules to my
initrd.img-3.13.0-48-generic built prior to install of extra, but found
graphics again ok but still no keyboard !
This report was made via a ssh session after booting with the
scrambled video.
