I installed bazzite on my PC with the option of gaming mode. I'm trying to figure out how to get LACT installed on this system so that I can undervolt my AMD card. I don't see the option in Bazzite Portal.

What's the correct way to install LACT on Bazzite?
Hi! After multiple attempts at trying to install LACT on Bazzite it seems like it ain't "compatible"? Whenever you click the "Enable AMD Overclock" it gives back a text box with one or two errors, I've read the Github explanation about a Boot Parameter solution, but when I go to edit the Grub file it doesn't even have the parameter that I'm supposed to add, when I added it manually it's like nothing happened (even after re-building the Grub file), so my understanding is that it ain't compatible yet? (Maybe I'm doing something wrong with the Boot parameter? It seemed a bit complicated)
Anyone else had this issue?
Hi there! Sorry if I'm being an idiot, but I've been trying to figure things out for a few hours, searching here and there but I'm still at a loss. I've recently taken the leap and set up a dual boot Bazzite, and so far having a blast, even though I have to relearn a lot of things.
Latest issue is I'm trying to set up an undervolt/overclock profile for my RX 7900 XTX, and managed to unlock all options in LACT, but nothing I do seems to apply. I figured I'd try undervolting first, but Mangohud still shows the same value. To make sure, I've tried setting the fan at a fixed 100%, but that doesn't kick in either after applying. Am I missing something? Yes, it's the correct GPU (I've disabled onboard chipset in BIOS).
Please don't bash me too hard.
Edit: my investigations and reading of https://gitlab.com/corectrl/corectrl/-/issues/460 point me to a driver level issue with my GPU, as I seem to be unable to change settings using Corectrl as well. Still investigating to clear the fog and try to find a solution/workaround.
Basically all I want to know is if there's anything I should install to further improve performance both for non-games/games.
Or is everything good to go with the Nvidia drivers installed And all that jazz.
I had missed this news recently with my view of Linux being somewhat narrower and newer - but it seems LACT has increased tooling for Nvidia GPUs.
For someone with lower experience this broadens the accessibility of GPU monitoring tools and brings me closer to parity with Windows GPU tweaking (wishlisting undervolting Nvidia for 2025!)
I had previously been following a script / command to limit power usage of my Nvidia card, however LACT seemingly does the same thing via a GUI slider - along with other helpful info about the GPU in operation. I was able to tweak the power slider and see real time results when applied and while running a game.
Unfortunately this failed to install correctly from the Bazzite portal as confirmed in the log, I believe perhaps because the portal halted for almost an hour and did not ask me for any root credentidals (as it did on subsequent attempts). Then when attempting again after rebooting - it reported it was installed, but was nowhere to be found after a further reboot. I eventually fixed it when following some instruction on ublue discussions (I'll edit with the link when I get home).
