So, I am writing this message from my other laptop running Ubuntu 14.04
I tried to reboot in rescue mode, but I don't know what to do from
there. 'startx' says that it doesn't have the proper files to launch
startx as root.

says : wrong login (doesn't even ask a pswd)
It's unclear how far you're getting.
Can you boot normally and get to a login prompt on a text-only screen?

Thanks for your reply. To get login prompt and text screen, I had to
take pictures with a camera, since the caracters are so small. Reading
back those images, I will say this :
upon booting, a number of screen messages do appear and scroll down
fast. I could only see that 'OK' was on most or all of them. In the end,
a screen with smaller characters appear for 2-3 sec, that I have
photographied.It has two lines as follows :
/dev/sda1: clean, 408719/60530688 files, 116865639/242103552 blocks
[ 8.436046] nouveau 0000:01:00.0: priv: HUB0: 085014 ffffffff (1e70820b)
Those two lines only appear for 2-3 sec, so I had a hard time to
photography them on the screen, and I am just coping them by hand, Links
for photos are as follows :

http://bdebreil.free.fr/IMG_0904.jpg
After those 2-3 sec, another screen appears saying (translated from
French to English)
"Oops, something went wront. A problem has occured and the system cannot
recuperate. Please disconnect and try again"
Countless trials have all lead to the same behaviour.
Now, if I reboot on rescue mode, a lot of fast moving messages do
appear, I only could see that most or all of them bore the mention 'OK',
as said before. In the end, smaller characters do remain on screen,
waiting till I submit the root pasword. Then :
You are in rescue mode. After logging in, type "journalctl -xb" to view
system logs, "systemctlreboot" to reboot, "systemctldefault" or ?D to
boot into default mode
Give the superuser pswd (or press CTRL-D) to continue : [ 9.315865]
[TTM] Zone kernel: A
Available graphic memory: 2097152 kiB
[ 9.316077 [TTM] Initializing DMA pool allocator
[ nouveau ..... DRM:
......
etc ...
When typing 'ls -l' home directories do not appear (see pictures)
Next I typed 'journalctl -xb' to view system logs : a dozen of pages
which I will shoot later, one thing I have noticed in it all, printed in
red characters :
EXT4-fs (sda2): unable to read superblock
this repeated three times !
Thanks in advance for your comments and advises.
