I've been working with ubuntu 18.04 for about a year now. I mostly use workstations but recently I wanted to switch to a laptop.

HP pavillon 15, AMD Ryzen 5 with AMD Radeon integrated graphic

I have an issue on the use of the HDMI output port, I can't get any video.

Here's the situation

when I try to check on display device:

*-display UNCLAIMED
description: VGA compatible controller produit: Advanced Micro Devices, Inc. [AMD/ATI]

fabriquant: Advanced Micro Devices, Inc. [AMD/ATI]
identifiant matériel: 0 information bus: pci@0000:04:00.0 version: c2 bits: 64 bits horloge: 33MHz fonctionnalités: pm pciexpress msi msix vga_controller bus_master cap_list configuration: latency=0 ressources: mémoire:d0000000-dfffffff mémoire:e0000000-e01fffff portE/S:e000(taille=256) mémoire:fcb00000-fcb7ffff

no really sure what what the keyword Unclaimed means..could it be a driver missing ? Based on that, I tried to update AMD driver but no luck on that. I unistalled it aftward

when I try to check on graphics

04:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Device 164c (rev c2)

There definetly somthing here on hardware side

when I check on overall system

OS information

I see that I have a llvmpipe (LLVM 10.0.0, 128 bits) as graphics, I tried to modify the grub i order to crrect it but didn't work..

After all, I thinking that maybe the GPU I'm using is too old to be supported on Ubuntu 18.04 And I should probably use a dock station to get mysecond display or update my OS to 20.4.

What do you think ?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
