[SOLVED] Screen breaks up, checkerboard like.

Should I try re-installing?

You could try an earlier version of Linux Lite but I would not expect that re-installing 7.4 will change anything.

Is there a way to see logs real-time?

Could try

Code:

journalctl -f

Ctrl C when you've seen enough.

If those messages only appear while the issue is present it suggests a problem between nouveau and the desktop environment/window manager

Without having the same hardware it is hard to know what to advise.

I've seen seemingly credible reports that editing this file

Code:

/etc/environment

by adding this line

Code:

GSK_RENDERER=gl

at the end of the file fixes various graphics glitches, none of the glitches mentioned seem a close match to your description.
Nothing to lose as you can undo the change by restoring the file.

A bit more searching found a GTK blog about the new rendering software
https://blogs.gnome.org/gtk/2024/01/28/n...s-for-gtk/

If you are using GTK on very old hardware, you may be better off with the old GL renderer, since it makes fewer demands on the GPU. You can override the renderer selection using the GSK_RENDERER environment variable:

which seems feasible

You could try the proprietary nvidia legacy drivers - if they work for your hardware. See the manual beginning at
