After receiving my new laptop I bought to code under Ubuntu Linux, I discovered that this product based on AMD Ryzen 4800H (Navi 14 Mobile) VEGA 10 with Radeon RX 5500M is unable to work with Ubuntu!

I am totally disappointed 'cause I bought it to work on Linux but all my tries with the following distributions failed:

  • Ubuntu 20.04 desktop, stucks on black screen after installation reboot.
  • Linux Mint works with nomodeset but a permanent banner indicating me missing graphic accelerator push me to try AMD Radeon software for Ubuntu 20.04 - since installation - I completely lost any shell command.

Only Windows works, Grrrrrrrrrrrrrr...

Please help if you have any ideas.

First of all, you should try using nomodeset (as you did).
Second, as Ubuntu (and Mint) are not really up-to-date compared to the new hardware, I suggest trying something in Arch Linux direction. The kernel used by Ubuntu is more than half a year old (with some fixes, but no major changes).
Third, you should NOT use AMD software from their homepage. The best you can do is adding a ppa (like Kisak's Mesa) for newer open source VGA drivers.
Fourth "Yes, AMD doesn't work. Nowhere on linux."
That's totally wrong. They are contributing a lot and the experience is really smooth in the past few years, but only with somewhat older hardware. What they really lack is to be able to have first day support, but after some waiting they won't disappoint you.

I finally solve my troubles with 2 options in grub.cfg :

  • amdgpu.exp_hw_support=1
  • amdgpu.runpm=0

With theses options, the laptop is usable for work but the autonomy is quiet bad... only 2h30 ...

All internal software is updated to last version firmware ...

No more AMD for Linux machine !

My issue got resolved with upgrading to latest kernel and adding following lines in /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX="amdgpu.runpm=0"
