Hi and welcome to the forum. I see you have Nvidia graphics and using Z15 Lite.
Have you checked for "Additional Drivers" in Software Updater?
Others on here with Nvidia graphics experience may be of more help than me. I do not to have Nvidia graphics.
I have done a websearch and found this item which could be of use, otherwise hang on for other helpers.
From Zabas link - the first reply /suggestion to ubuntu-drivers autoinstall is a good one, but I would suggest as a follow up that the Nvidia-430 would be a better choice currently to the one offered in that thread (Nvidia-390).
Ok, system log is empty. For kern.log, you may need to open it in GUI with a Text Editor and paste the contents here.
Your inxi -G output is a bit sparse. Not sure why - though it may be an Nvidia thing...
Does your computer have integrated AMD graphics as well as the Nvidia Graphics card?
According to inxi, the Nvidia Proprietary driver (Either 390 or 430) is not being used and it is still using Nouveau.
Are you able to boot into the GUI desktop?
If not, are you able to if you hit the e at the boot menu and add the kernel parameter "nomodeset"?
You can do this at boot by choosing "Boot with safe graphics" or by the following; https://www.udoo.org/docs-bolt/Operating_Systems/Linux/Known_issues.html
