I have an ASUS Laptop that as an AMD ryzen 35550H ( Vega 8 ) and an Nvidia GTX 1650m.I installed kubuntu 20.04 on it, upgraded to the liquorix kernel and installed the driver for my wifi card like normal but when i wanted to use the nvidia dGPU i found an issue.

Nvidia prime and the nvidia drivers are installed.

It was working when i was using PopOS! so i searched their github on found this : https://github.com/pop-os/system76-power/issues/73

But i don't know how i can use their version of ubuntu-driver-common or even if i should, because when i had any of their repositories, apt says they don't have a release file.

Don't hesitate if you need more information.

  • It seems that AMD + Nvidia doesn't work yet. – Pilot6 Jun 6 at 10:25
  • Well i kinda figured out that, but since it's dead easy to get working in PopOS! , i supposed i wasn't understanding something. – Shun_kanji Jun 6 at 10:43
