Oh, Ubuntu does boot on such hardware just fine. And seeing how well it works I'd feel guilty of wasting money and polluting the environment when buying newer hardware.

It does not boot all up into native Wayland. Nevertheless, one can run X11 just fine.

How to turn Wayland off? Key is to disable it in /etc/gdm3/custom.conf. Code ('WaylandEnable=false') is already there, just commented out. Accordingly, to get the hardware booting all up to the desktop, proceed as following (written from head, so actual wording might be slightly different):

- Turn the PC on.
- As soon as the Grub boot selection screen appears, use up and down arrows on the keyboard to select 'Ubuntu (recovery mode)'.
- Hit 'Enter'.
- After a while, another selection screen appears. Select 'Enable Network', which happens to be a simple way to re-mount the boot disk in read-write mode.
- Back on the same selection screen, select a root shell.
- Being at the root shell, enter 'vi /etc/gdm3/custom.conf'.
- Using arrow keys, navigate to the line reading '#WaylandEnable=false'.
- Make sure the cursor is over this first '#'.
- Hit the 'x' key once, the '#' should disappear.
- Enter ':wq'. This gets you back to the root shell.
- Type 'reboot' and hit Enter.

From there on, your hardware should boot all into the desktop as if it had been the case all the time.

Another way to get this file edited is to boot another OS on that hardware or to physically connect the disk elsewhere, of course.
