I have a dual boot PC running Windows 10 and Ububtu 18.04.4, with 5.3.0-51-generic kernel. With windows the graphic card work perfectly, on Linux I'm experimenting a lot of trouble. I tried to instal amdgpu and the installation goes well with the last version of the driver (20.10), but after reboot, the screen was flickering so fast that the only login was a hard operation. Now I tried to follow the second point of this guide but it also has no effect. At least neither negative effect.
The output of my sudo lshw -C video
is:
*-display UNCLAIMED

The information screen say i'm using llvmpipe (LLVM 9.0.1, 256 bits)
as you can see here.
So I would like to use the proper driver, can anyone help me?
EDIT
I think I miss the kernel modules of amdgpu, lsmod |grep amdgpu
give no result and in my lspci
output the Kernel modules
voice doesn't exist
lspci -k | grep -EA3 'VGA|3D|Display'

Also $ sudo lshw -c display | grep driver
doesn't give any output.
glxinfo
, instead, tell me that direct rendering is Ok
$ glxinfo | grep render
direct rendering: Yes
