I need your help, please!
EDITED! (See below)
I use Ubuntu 16.04 LTS, and my "home folder" is encrypted. When I put on my computer, I insert my "encryption password" and it is well accepted, but Ubuntu never start, and so, the following message appears:
: 2.066866] [drm:intel_set_pch_fifo_underrun_reporting [i915]] *ERROR* uncleared pch fifo underrun on pch transcoder A : 2.066887] [drm:intel_pch_fifo_underun_irq_handler [i915]] *ERROR* PCH transcoder A FIFO underrun : 2.082464] [drm:intel_set_cpu_fifo_underrun_reporting [i915]] *ERROR* uncleared fifo underrun on pipe B : 2.082483] [drm:intel_cpu_fifo_underrun_irq_handdler [i915]] *ERROR* CPU pipe B FIFO underrun : 2.231106] sd 6:0:0:0: [sdb] No Caching mode page found : 2.231142] sd 6:0:0:0: [sdb] Assuming drive cache: write thorugh Welcome to the emergency mode!

(I have hand-typed the previous code)
As I don't know how to fix this problem, I wanted to recover my data in an external hard disk by initializing from a LiveUSB (not the same as the hard disk), and so format my computer. But, my new problem is I cannot open my encrypted "home folder".
When I open my encrypted home folder through the LiveUSB (using "sudo nautilus"), I find two files. The first one is "Access-Your-Private-Data.desktop", and, the second one is a *.txt called README which contains the instructions to open my home folder. So, I have two options:
A. [Double click on the file "Access-Your-Private-Data.desktop"]: The problem here is, this file opens a windows (like a terminal) which close immediately, and never ask me for my encryption password.
B. [Type the command "ecryptfs-mount-private" on the terminal]: The problem here is, I obtain the following error:
ubuntu@ubuntu:~$ sudo ecryptfs-mount-private ERROR: Encrypted private directory is not setup properly
Also, I have used the command "sudo ecryptfs-recover-private", but I obtain the following problem:
ubuntu@ubuntu:~$ sudo ecryptfs-recover-private INFO: Searching for encrypted private directories (this might take a while)... find: ‘/run/user/999/gvfs’: Permission denied find: File system loop detected; ‘/sys/kernel/debug/pinctrl’ is part of the same file system loop as ‘/sys/kernel/debug’.
I hope you can help me. Thank you!
EDIT: Well, finally I fixed the problem. First of all, I had to find the correct directory containing my encrypted "home folder", for that, I typed the following command:
sudo find /media -type d -name .Private
In my case, I obtained:
Finally, I used the command "ecryptfs-mount-private" as follows:
sudo ecryptfs-mount-private /media/ubuntu/29b0ca4e-58f3-4802-9682-2a1aa42bb121/home/.ecryptfs/arcisd/.Private
I hope this is useful for someone more!
