Video driver on Ubuntu 21.10

I'm kind of new to ubuntu and I'm having some problems with drivers for my gpu [RADEON RX 550].

when I first installed ubuntu it automatically set "Radeon RX 550 Series (POLARIS11, DRM 3.41.0, 5.13.0-19-generic, LLVM 12..." as the default driver. It happened that I tried to install the official AMD drivers but the process failed and after the reboot I'm stuck with "llvmpipe (LLVM 12.0.1, 128 bits)" driver wich disabled all the animations and made the system laggy. Does anyone know how to at least get back the original one? Let me know if you need further informations.

I have /etc/modprobe.d/blacklist-amdgpu.conf that contains blacklist amdgpu.

Solution 1:

Delete this file by

sudo rm /etc/modprobe.d/blacklist-amdgpu.conf

and reboot.

You installed wrong drivers that blacklisted the original one.
