Hi Lukasz,
I needed to update an old laptop that had been in an office ever since Covid and Lockdown began.
Details: HP EliteBook 8730w with Nvidia graphics.
Installation media: USB memory stick with 20.04.2.0 desktop image on it.
Installed this on it:-
$ sha256sum focal-desktop-amd64.iso
93bdab204067321ff131f560879db46bee3b994bf24836bb78538640f689e58f focal-desktop-amd64.iso
93bdab204067321ff131f560879db46bee3b994bf24836bb78538640f689e58f focal-desktop-amd64.iso
OK, so it *does* install OK and it *does* boot.
However it gets very hot and crashes, with only the mouse pointer moving. Personally, I think it *might* be an Nvidia problem.
I did choose to install the 3rd party software etc. Maybe I should have avoided that? So I rebooted and quickly went into "Software & Updates" chose "Additional Drivers" and told it to switch from the Nvidia driver to the Nouveau device driver. Exercised the system a bit, using gnome-clocks as a timer. So far it has gone on for just over 20 minutes without crashing. Kudos to the nouveau team!
HTH,
Ian
