Help with GPU drivers in ubuntu

[cheloxnz]

Hi everybody how are you? a question, I have ubuntu in version 20.04, I wanted to know how to install the drivers for my gpu, I have an apu a6-7480 r5 series. Thank you very much.

cheloxnz; Hello - Welcome to the forum.

What leads you to the assumption that you need to manually install a graphic's driver ?
In most cases the drivers are included in the kernel.

Post back - between code tags - the output of terminal command:

sudo lshw -C display

And we see here what story gets told - and go from there.

all in the process

sudo ubuntu-drivers autoinstall

I think amd drivers are automatic. Intel are. nVidia works wth the command above.

Don't go looking to manually install drivers outside the packaging system without very good reason. There are long term ramifications.

At install time, if the installer detects a supported AMD GPU, the amdgpu driver will be "installed" -- actually, the existing module in the kernel will be used. If the hardware is not supported by amdgpu, the existing radeon kernel module will be used.

You need do nothing more when installing on a machine with AMD graphices, provided it is not a hybrid graphics setup with Intel and AMD graphics hardware. That is not supported well by the industry and the Linux developers are left to drown. The correct AMD module is loaded, but the AMD module and the Intel module may be at odds.

Would you please use the terminal and post the results of

lsmod | grep amdgpu

and

lsmod | grep radeon

The first queries the system to see if the amdgpu module is loaded. The second queries the system to see if the radeon module is loaded.

lsmod lists the loaded modules. That is piped to 'grep', which is the commend for global regular expression print. That will list modules related to amdgpu or radeon.

The problem is that I have 2 monitors, in windows they worked perfectly for me, I have windows and ubuntu, I start windows and both work perfectly, I start ubuntu and only one works. One is connected by HDMI and the other VGA. And I thought maybe they flataban drivers.

Yes, I thought that, but as I mentioned above, due to the non-functioning of a monitor. Thank you

The fact that no driver is being shown for the AMD on your system is concerning. Need to wait for someone with an AMD GPU to respond, it seems. Sorry.
