Fix console text (resolution/alignment) - F30, 340xx driver

Hello and thank you. This is an old desktop with Geforce 8600GT and a 17" lcd monitor. fedora 30 installed from minimal with xorg and Xfce. I have installed the nvidia driver from rpmfusion but in trying to fix the console resolution and the text being off the screen limits I eventually messed things and re-installed. At first, I installed grub to a partition and since I hadn't enabled the Boot Loader Specs in it, it confused me. Now after re-installing I'm back using nouveau and have understood the way grub works. The proprietary driver works much better so I want to use it. The problem is that the 340xx driver package from rpmfusion sets 'GRUB_GFXPAYLOAD_LINUX=text' and this makes the console almost unusable as it sets a 800x600 resolution and text is off screen (like e.g., I would need to hit enter two times just for the cursor to appear). Why is that setting? Isn't it possible to use the default resolution in the console (currently 1280x1024, but even 1024x768, with proper text alignment, would do)? I don't care about plymouth but need to be able to use the console. Can I trust that after installation I can revert 'GRUB_GFXPAYLOAD_LINUX=text' to some sensible resolution (even if set with ‘GRUB_GFXMODE’)? The 'text' setting is just some pre-emptive measure or is it really needed? Thank you very much.
