Ошибка cinnamon session failed

I’ve had Mint Cinnamon 18.1 installed on my ASUS UX310UQ for some 2 weeks now.
Everything having been fixed, it was working fine… Until tonight.
On booting the machine, during linux initialisation, a small windows open in the middle of a black screen:

your session didn't  even last 10sec. If you didn't disconnect yourself, there is an install problem or shortage of disk space.
Try to connect to a rescue session to fix it.

details (file ~/.xsession-errors)

inictl: failed to connect to socket /com/ubuntu/upstart
connection refusee [mdm]1277: Glib-CRITICAL: g_key_file_free: assertion 'key_file !=NULL'failed

Then, on validation of this window, initialisation process continues until a «session opening» window is displayed with a nice picture, and a small window showing my user name and asking for password. On entering this password, process continues for a few second with black screen, then it shows the same session opening window again and we are locked in that loop, with the only possibility to shutdown or restart.
And then, back to rebbot and the beginning of this post.

From there, I am a real beginner, and apart from re-installing Linux, I have no idea of what to do or check to fix this.
I’d greatly appreciate any kind of help to jump out of this mess…

When I start Linux Mint 17.3 in Virtual Box environment, it always fails to GUI login.

I have to change CUI login UI by Shift+Alt+F4, then run startx.

After that everything works fine.

This is the detail of the error:

~/.xsession-errors

    syndaemon: no process found
    /etc/mdm/Xsession: Beginning session setup...
    /etc/mdm/Xsession: Executing cinnamon-session-cinnamon failed, will try to run x-terminal-emulator
    /etc/mdm/Xsession: 205: exec: x-terminal-emulator: not found

How can I solve the problem?

~/.profile

#umask 022

# if running bash
if [ -n "$BASH_VERSION" ]; then
    # include .bashrc if it exists
    if [ -f "$HOME/.bashrc" ]; then
#       . "$HOME/.bashrc"
    fi
fi

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

# Add $PATH
export PATH="$HOME/bin:$PATH"
export PATH="/usr/local/sbin:$PATH"
export PATH="$HOME/.rbenv/bin:$PATH"
export PATH='/usr/local/bin:$PATH'

This is my ~/.profile file.
