Which card and which drivers? I switched from Windows 10 to Xubuntu last year and have had endless issues with my Nvidia card (GTX 970). At the moment, I can't even use the desktop without annoying flickering & hard to diagnose / fix bugs.
Its an old card so I have no idea why I'm still struggling to get it to work. Is it perhaps because I'm using Xfce? I heard that Nvidia cards play better with Wayland although I haven't tested this myself.
I run a GTX 970 on Fedora 44 KDE Plasma (Wayland) without issues. Make sure to use the 580.xx Nvidia driver.
Anything between 700 and 2000 series (inclusive) is in this "completely proprietary due to signed firmware but also not fully supported in Wayland" zone. You need to have at least 3000 series to have proprietary drivers with open kernel driver and good KMS/GBM/Wayland support.
I can't speak for the parent but I have a 5090 and it works perfectly fine
