My R8 box got sick. Replaced Mobo with new video. Runs fine except that video in the GUI is 40x80 or something like that. A new install would have detected the card and set it properly. Doe anyone know how to get the OS to reset the video parameters or where the data is stored. – I’d add a picture, but…
Depending on what desktop you’re using, there’s likely a monitor setup program hidden away somewhere under the main menu.
On Mate, it’s Main Menu - System - Preferences -Hardware - Displays
It’s probably somewhere around the same area on other desktops.
Thanks Frank,
I’m afraid it’s not the monitor. I tried that. Without the gui I get a 24x80 1960’s display . It’s somewhere in “grub” or something that runs in the initial install.
Are you talking about the initial boot screen or your desktop “gnome”?
What is the default resolution of your monitor?
What is your new video card?
Install inxi
sudo dnf install inxi
after it is installed:
sudo inxi -cmMGAN > wsSpecs.txt
Or you can get even more graphic info with this:
sudo inxi --edid > inix-edid-out.txt
the edid-out file should give us the most relevant information.

Package inxi-3.3.30-1.el8.noarch is already installed.
Dependencies resolved.
Nothing to do.
Complete!

It’s not just gnome, it’s the basic os install …
Thanks for the try…
On the theory that inxi isn’t the only girl in town, I installed “Hardinfo” -
It’s output is interesting…

Hmm, suggestions?
When one installs Rocky (or any other distro) the software runs out and figures out what the machine is like. I suspect that “hardinfo” reads some tables / files somewhere. Somewhere there’s a grimoire that describes the process of linux installation, module by module.
Documentation is such a tricky business.
My suggestion is to do a fresh install.
Not knowing what state your system is in, as per the errors in your post is just too much to trouble shoot as there is the chicken and egg problem.
I hate that answer, but thanks.
Too many spinning plates right now to wash dishes.
If I do that, 9? instead of 8?
What GPU did you originally use? What CPU? Was the GPU the one integrated with the CPU, integrated on mainboard, or an add-on card? What about now?
For example if you were using an nVidia card & their legacy, not OpenSource drivers, those could be the issue.
