I was thinking about finally buying a dedicated GPU for my computer. Reading this, it's gonna be harder than I thought. NVIDIA has an issue with not working with system RAM properly which was discussed earlier in the thread and all the budget cards it offers have, comparatively, very little VRAM. Seems like it's suffering no matter what you pick, unless you shell out the big bucks for something top-of-the-line (not ideal).
This is anecdotal of course and I know it is a real problem, but you don't really tend to hit that ceiling ever in my experience on NVIDIA. I have used both a GTX 1660 SUPER and a RTX 4070 on Linux, I only use Linux to do all my computing tasks and I use it for hours at a time. I perform heavy tasks on it like gaming and cuda rendering, I also play music and videos on a browser while doing these things. The only time was when I was trying to run an AI model that was too demanding and that was on the GTX 1660 SUPER, and even then it just told me "hey idiot, your VRAM is too low for this" and then exited cleanly. I say try it but go with NVIDIA, you can get a cheapish modern card from a 70 line one and most likely still be fine. - If you run into problems still you might get some luck with doing something like offloading tasks to the iGPU which I guess would serve to "share" your VRAM by performing some tasks reserved for it over the dGPU. I have never had to do this personally, but again that is anecdotal. Some have had worse luck with this tbf however it's not really super widespread, I only learned of this NVIDIA flaw from that post in this thread, and that was months of using NVIDIA being none the wiser.

AMD is treated as the budget brand (which in GPUs isn’t entirely inaccurate), so the OEMs cut every corner they can.
I think you can probably be fine going amd too, just do research on the specific gpu you are buying, and the drivers you will be using with it. I feel like you could run into issues with either brand potentially.
I've never really used premium brand NVIDIA cards though, it's both a card I got used like all my NVIDIA cards and a "mid tier" (according to the pundits) one. We know NVIDIA does some corner cutting on their less premium cards, at the very least they nerf the VRAM, yet I've never felt any problems from whatever they do to make more profits. Why? I have no idea. Maybe NVIDIA just have better build practices for their entire line up or perhaps they have better people working on them? I am not even going to pretend to know the differences between AMDGPU and NVIDIA's architectures, so I have no clue personally. The issues @dec05eba and others around the web are describing with AMDGPU on both Linux and esp Windows sounds like a nightmare to deal with and I can honestly say I've never had any issues like that at all w/ NVIDIA on any system. And some of the people with issues have like the top of the line cards too. The budget option might have been tempting, but you can get used NVIDIA for cheaper than a lot of AMD stuff in my area and/or work. Either I scavenge off a work colleague's* comp if I can or I get one from a gamer who is feeling FOMO for a new generation. And I don't need to change them for a long time either, my last card I used for well over 5 years, it was a mid tier too but it still chugs along just fine.
For what it's worth, I've never had any serious problems with AMD on Linux. The only thing I've encountered is that Xorg will crash eventually if the monitor's off for more than a few hours.
Make a config.d/ file?
Is this a config for xorg? Or something else. If it's xorg, like they suggested above me. But put it in. /etc/X11/xorg.conf.d/
thats the thing
lxqt-config-input binary to change those settings and i cant find anything related to lxqt in /etc/
Ok. Assuming you are running it on xorg. Maybe check to see if there are files being created or changed in the /etc/x11 directory when you change settings.
okay...
Ok. Yeah I guess just wait and see.
okay, ive reinstalled tlp, because i know this triggers the config reload
You could try "echo 1 | sudo tee /sys/class/drm/card0/device/pp_power_profile_mode"
I had that problem with Wayland on rdna2 but it's been resolved
If the config settings are written to session.config, they probably are supposed to be written to session.config, not those other files.
session.conf isnt overwritten
