the system freeze

What did you do to try and unfreeze it?

It looks like GDM is having problems, do you get this issue if you drop the display manager?

Also, which version of Debian are you using and what is your hardware?

Try systemd's journal, that may have more information:

https://www.digitalocean.com/community/ ... stemd-logs

Note that persistent journaling will have to be enabled, for instructions see

Code: Select all

man journald.conf

if I stop gdm3 via systemctl I get a black screen with a blinking underscore, to go back I have to press ctrl-alt-F1 to use console.
I update the first message of the post with info.
Journal is enabled.

Yes, that is the expected behaviour.

For testing purposes, let us see if a simple openbox desktop will start; first install openbox:

Code: Select all

# apt install openbox

Then set your box to boot to a console screen:

Code: Select all

# systemctl set-default multi-user.target

Now reboot and try to start the desktop from the TTY command line:

Code: Select all

startx /usr/bin/openbox-session

You can re-enable a graphical login afterwards with:

Code: Select all

# systemctl set-default graphical.target

And we really do need to know which Debian version you are using, the booted kernel type doesn't actually tell us this...

Code: Select all

apt-cache policy

it is Debian 8.
The freeze are random, for example now all is working fine.
I really don't know.
It happened when I watched youtube videos but I'm not sure it is youtube.
Currently I'm using mate which is light.
