Access shell locally

sorry to ask that again, but I’m unable to access the OSMC shell

I found the wiki page here Accessing the command line - General - OSMC

Pressed ESC while the splashscreen was visible (only one press, not long, no other key pressed before and after that).

Then I see the linux login screen for a few seconds and it fades away replaced by OSMC screen.

Did I miss something ?

Well you need to login. Without login action the watchdog will restart the GUI (Kodi)

Oh you’re right, but I had to do several tries to be able to type my login and password in less than 2 seconds …

Should not be 2 seconds, I think the watchdog timer is 30 seconds
