Hello ! I finally decided to leave my toxic relationship with Windows and i switched to mint yesterday, though keeping a dual boot for now.
Im having trouble working out about my graphic car on two things:

  • First, ive got an Ideapad gaming (Lenovo) with an AMD Ryzen 5 5600H with Radeon Graphics × 6 as a CPU + integrated graphics, and a NVIDIA Corporation TU117M [GeForce GTX 1650 Mobile / Max-Q] as GPU
    I would like to know (or if you have some articles about it maybe?) how does mint split the work (not in detail, keep it simple) because i dont want one card being pushed too much while the other do nothing. I saw online that by default the AMD was used for desktop work while the NVIDIA was used for games, but i'd like to be sure. Ive also checked that my GPU was recognised and it is, i also installed the latest drivers through the drivers manager.
  • Second, i can't seem to find out how to push my fans. On windows, i could press Fn + Q to change the fans behavior, and when i looked online for mint i saw that people could control their fans using the nvidia settings (sudo) ; tho for me it doesnt appear in the options. On some forums people said that sudo was needed, along with secure boot turned off, which i did, but no option show up about fans. Im worried because i tried launching the same game on Mint/windows and while windows burst the fans full speed (as wanted) mint do not at all, but the fans do speed up a little. i enabled the "NVIDIA Performance mode" in the nvidia settings and did not changed anything else . If anyone could help me with that, i would be glad !

Thanks in advance and for reading all this, if i forgot any important point please @me and ill give you the missing infos !

i used to control my fans with Afterburner. But in linux I noticed that nvidia has its own way. it won't start the fan unless the card goes over 60 C. So it stays quiet until then. It was designed that way.

nvidia-smi will show you which programs use the nvidia card.

the 'on demand' option in your nvidia system tray icon is recommended as performance mode has been giving trouble for some people on linux
