There is no compilation necessary. Using the above link you just
download the package set for a given version and install the set as one:
sudo dpkg -i *.deb
But certainly don't do that if it's a production machine and you have an
acceptable workaround.

Bug description:
I've just updated to 22.04 on 3x boxes: 2x laptops and 1x tower.
Laptops went well as they are standard running wifi (note to self:
next time upgrade one using a USB docking station+as many externally
attached devices as possible should prove in a quite pleasurable end-
user experience)
For the tower: this is the dual-screen portrait system I have been
opening up defects for months now. Same config too. Anyways, after I
rebooted the overall booting process happened pretty well until TTY7
tried kicking it and totally failed doing so hence rendered my system
totally broken.
The behavior of my screens is that they started blinking from blank to
another type of blank for =<1 second each state. But during one of
those states there seemed to be Wayland as I could just see the mouse
cursor fly around when activated.
Accessing other TTYs was also impossible as even though pressing
CTRL+ALT+F2|F3|etc would indeed display a login prompt that within
that same blinking instant that it had altered back to only that
blinking cursor symbol(_) at the top-hand-left.
That behavior held true for all TTYs.
Pressing the power button did showed up the UM symbol alongside
standard shutdown routine happened OK.
Solution was: unplug one of the two monitor and automagically jammy's
login screen popped up.
If I replug that 2nd monitor while I am inside a working TTY7 session
then the same (original) problem happens in which I cannot use any of
the screens and when I re-unplug one of the two screens again I am re-
back again at the jammy login having lost the current session that I
had.
Both of my screens are the same model and both use HDMI.
I have attached my ~/.config/monitors.xml
