Ah still a problem I see... "sudo startx" is definitely not going to
work out for you for various reasons but let's not get into that or the
space issue which are both false starts.
The trick is to persuade your system to cough up specific information on
exactly _what_ it thinks is wrong which is sometimes surprisingly
difficult. Xorg/Xwayland issues aren't captured in journald quite the
way you might necessarily expect and that seems to be your issue here as
a console login works just fine.
I'd do a clean reboot, login over SSH from a working machine (makes it
easier to copy/paste stuff from if required) and do some more recon. At
the login screen check first to see what type of session you're using by
default - there are properly different options to login using Xorg or
Xwayland, quite probably not clearly labelled as such. Try both. You may
have a simpler WM installed which will work when complex WMs like Gnome
or KDE might choke on a failed dependency somwhere - like Awesome or i3
for example. If not, don't worry about it for now.
See what the following have to say for themselves once you've rebooted
and tried a couple of graphical logins:
systemctl --failed
sudo journalctl -p err -b
dmesg
You can also try running "sudo journalctl -b -f" in a console and then
trying to login graphically which will tail journalctl in realtime and
show you what is happening.
I suspect you _still_ won't see what the root cause is though and my
suspicion is that Xorg is dying in some weird way probably due yet again
to kernel mode setting and driver misconfiguration.
Can we just check the system is fully up to date and what kernel are you
using?
