Cinnamon problen at login!

[joellapointe1717]

Hi,
I rebooted my computer. Once at the login screen I did put my password to gain access to my desktop. Then, a popup messages appeared:
"You are currently running in fallback mode.
If you suspect the source of the crash is a local extension, applet or desklet, you can disable downloaded add-ons using the checkbox below.
Do you want to restart Cinnamon?"
I did try the yes and no options with including the checkbox which says: "Disable download applets, desklets and extensions."
Nothing happened, so I did rebooted with the physical button multiple time. I did try to gain access to the terminal with: Ctrl+Alt+T or Fn+T or Windows button+T. My intent was to install an alternative desktop system such as Xfce.

Is there a way to get acess to the terminal?
Furthermore, I'm not a programmation oriented person. I can do some minimal terminal work such as updating, installing software...

Thanks

Hi there, do you remember what you were doing before the reboot that caused the problem? Were you adding or removing packages or did you update the system?

Hi, have you already checked in ~/.xsession-errors if there are errors?

[joellapointe1717]

It does that :
joel@Spiral:~$ ~/.xsession-errors
bash: /home/joel/.xsession-errors: Permission denied
joel@Spiral:~$ sudo -s
[sudo] password for joel: *******
root@Spiral:/home/joel# ~/.xsession-errors
bash: /root/.xsession-errors: No such file or directory
root@Spiral:/home/joel# nano ~/.xsession-errors
root@Spiral:/home/joel#

The files doesn't seems to exist!

try less ~/.xsession-errors as normal user (when you enter in cinnamon and fail to start) or less /home/joel/.xsession-errors for see it (and no execute, is not a binary but text file)
If you do nano ~/.xsession-errors will try to edit the root one that normally should not exist
"~" point to the home profile for the current user

caja is default filemanager of another desktop environment (mate), cinnamon default is nemo instead, so I suppose in latest graphic session you have logged in mate and not cinnamon, right?
for see log related to cinnamon you should try to login in cinnamon and after look .xsession-errors
