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 description: VGA compatible controller product: Advanced Micro Devices, Inc. [AMD/ATI] vendor: Advanced Micro Devices, Inc. [AMD/ATI] physical id: 0 bus info: pci@0000:0a:00.0 version: c5 width: 64 bits clock: 33MHz capabilities: pm pciexpress msi vga_controller bus_master cap_list configuration: latency=0 resources: memory:e0000000-efffffff memory:f0000000-f01fffff ioport:e000(size=256) memory:fcc00000-fcc7ffff memory:c0000-dffff
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?
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

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