I ran Antergos like a charm when suddently, the system froze at startup : I have the lightdm banner, it’s “mooving” (the date moves some times) but the mouse is frozen, the keyboard is muted and no keys are working.
I have to press on/off button 5sec to stop the computer.
The pixel definition of the screen is like there is a video problem (wrong resolution)
It’s a latop Lenovo X220

I tried to boot with rescue or emergency mode but I don’t know what to do after.
I don’t have network in these modes, so I can’t make an upgrade of the system.

Any help please !!!
