Disabling my AMD IGPU/Living with Hybrid Graphics
I'm coming to understand that Linux has a lot of issues with hybrid graphics and am trying to find ways to work around this. I'm not sure this is possible since it doesn't seem this laptop has a MUX switch and it doesn't have an easy option like turning it off in bios. I've tried adding radeon.nomodeset=0 to GRUB but it doesn't seem to have done anything. Can anyone give me any other ideas to try? Or other general ideas for dealing with hybrid graphics I can't disable? Specs: Radeon Pro 7 w/ Radeon 780M IGPU Nvidia RTX A1000 GPU Unknown laptop motherboard 16G RAM UEFI Laptop Model: Thinkpad P16v Gen 1

Computer Generally Suffers Under Linux. Likely a Hybrid Graphics Issue
Laptop Model: Thinkpad P16V Gen 1 CPU/Integrated Graphics: AMD Ryzen Pro 7 w/ Radeon 780M Graphics DGPU: Nvidia RTX A1000 Distro: Bazzite 41 Desktop Environment: KDE At this point I have been on the Linux Grind for several months now. I have tried Fedora, Pop OS, Pika, Nobara, Ubuntu, Mint and probably even a few I can't remember right now. Regardless of how customized or optimized the OS is out of the box this laptop has always suffered from rainbowy graphical glitches, and wildly swingy performance between distros that never seems to make any sense. I have tried Ubuntu, Debian, Fedora, and Arch based OS-es and they've all suffered from some kind of general incompatability with my DGPU that renders games varying levels of playable to unplayable and I can't figure out any kind of pattern or fixes. Right now in my system info it lists only the integrated graphics and I'm beginning to think this might have something to do with the computer never properly using the DGPU, even though it's set to Hybrid in the SUPERGFX plasmoid. I am desperate for any kind of advice that will make this thing work properly. Please if anyone can help I dread the day I'm forced to return to windows, because If something doesn't change that day is close at hand. Readout of
