Xubuntu 18.04 graphics issue

My i686 laptop has problems with all updates of onwards (32 bit version). The screen shows just a few lines of coloured mess which is totally unreadable.

Might the introduction of the nouveau graphics drivers be the cause and, if so, how do I bypass the problem ? When were the nouveau drivers introduced ?

I haven't used Xubuntu, but when I upgraded my desktop (uses an nVidia card) from Ubuntu 16.04 to 18.04, the upgrade installed Nouveau and messed up my display pretty badly, though not as bad as what you are seeing -- mine was readable. If you upgraded from 16.04, do you know what driver 16.04 was using?

Some time after my 18.04 upgrade, I discovered that the Nouveau package description suggested installation of an accompanying firmware package which the 18.04 installer did not install. I have since been wondering if that would have made the Nouveau driver work. What I finally did was to identify a proprietary driver using the command

ubuntu-drivers devices
and then installing the recommended driver. This cleaned up my problems.

output of

cat /var/log/Xorg.0.log
cat ~/.local/share/xorg/Xorg.0.log

You might need to boot into recovery first, or add nomodeset to your grub's linux command.
