[hector freschi]

I upgraded my PC from Uuntu 20.04 to Ubuntu 22.04.
When I rebooted, the screen froze and gave an error.
There was no way to stop it from happening. Apparently I couldn't find the graphics card.
I burned Ubuntu 22.04 on a DVD, and from there I put it in the pc...
I left it for 12 hours, and then rebooted. Although buggy, it was able to run Ubuntu 22.04.
But it is unstable, and I fear that if I reboot the pc, it will crash again.
Sorry for my English, but it would be nice if it could be written in the native language of each region.
Thanks and greetings.
