AMD integrated graphics not working with amdgpu driver in X, AMD Ryzen 9 7900x

miev · 05-03-2025, 07:27 AM

Do AMD integrated graphics work in Slackware? I have AMD Ryzen 9 7900x with integrated graphics. Xorg only works with framebuffer video driver max 1024x768 resolution.

Do you run 15.0?
If so, you have an old-ass kernel that will probably not support this rather new GPU.

Try Slackware current.

Yes, 15.0. I quess it is that. Upgraded to newest, tried different configurations. It just don't load the module and there is no screen for X. Other machines with intel chip, it works just fine.

Maybe I'll try current but I would like to stay stable with this. So I might use something else.

Btw. In Debian install it says that there is possible missing firware for module amdgpu. I have not not yet figured does it find firmware or why it find screen and works. Newer kernel I quess? (6.1.129-1)

Maybe I try to build a new kernel for 15.0. Never done that. Any suggestions / best practices. How to start? At least some hint which one to choose from kernel.org.

A good start would be the configuration file of the Slackware 15.0 kernel which you can get with a command like:

Code:

cat /proc/config.gz | gzip -d - > .config

Put that .config file in the top level directory of your new linux kernel source tree and start by running:

Code:

make oldconfig

An alternative start for you .config file might be the kernel configuration files from Slackware current.

After that, you can apply any patches if you want to and make your own customizations to the kernel configuration with:

Code:

make menuconfig

or

Code:

make xconfig

if you are running X (preferably as a normal user)

Once you have the kernel that configuration as you want it it is time to build the kernel:

Code:

make bzImage

...and the kernel modules:

Code:

make modules

Install the new modules with:

Code:

make modules_install

and install the newly built bzImage in your bootloader. You might need some extra steps to update an initrd if you start with the generic kernel configuration rather than the huge kernel configuration.

This method allows your newly built kernel to live side by side with the stock kernel if you configure your bootloader to choose between them. You can also study the build scripts in http://ftp.slackware.com/pub/slackwa...15.0/source/k/ (or your favorite mirror) if you prefer to build Slackware packages with your custom kernel.

If I wanted to update the kernel on my Slackware 15.0 system I would probably go for the latest 6.12.26 longterm version. But your choice of kernel version completely depends upon your reason for trying a newer kernel.

I was in a similar spot: see switching from an intel to an amd system without reinstall?

The difference is that my APU (=CPU with integrated graphics) is even one generation newer still than yours. So you might have better luck than me. But for me, I needed to upgrade mesa too to support the hardware, not just the kernel. And I failed at that. It's documented in the thread starting from post #7.

PS: I think your thread would have better been posted in the regular Slackware forum, not its Installation subforum.

I documented a quick and dirty test here which told me what hardware was compatible with two different kernels. As far as I checked, it was accurate even though it was QnD.

Yes.
Probably need to be on a 6.x kernel however. The system is a OLED laptop circa 2022 running flicker-free at 1920x1080.
