AMD Ryzen 5 8500G Radeon 740M drivers - debian 12 xfce

[frazered]

Hello,

Just built a new AM5 system. Put Debian 12 xfce on.

AMD Ryzen 5 8500G with radeon 740m integrated
Asrock X600-STX deskmini
32gb ddr5

Looks like stuck in 800x600 resolution. There are no other resolutions available. I have installed amdgpu as per https://wiki.debian.org/AtiHowTo

But still stuck in 800x600. (running a 4k monitor usually)

For an experiment ubuntu and fedora seem to work, but I really want to stick with debian.

Are there any other drivers or kernels that can work?

Many thanks in advance.

GPU drivers are part of the Linux kernel. It can be updated from the backports: https://forums.debian.net/viewtopic.php?t=159363
Additionally you can update the firmware from the backports, I think this should be the firmware-amd-graphics package.

There are two entries of Debian 12 on linux-hardware.org which say the processor works: https://linux-hardware.org/?id=cpu:amd- ... m-graphics, one even with the kernel 6.1. So in principle the processor works with Debian.

You could check the logs for lightdm messages with

Code: Select all

journalctl -xb | grep lightdm | less

Or all errors during boot with

Code: Select all

journalctl -p 3 -xb | less

If you don't know the less command, you can navigate with it through the output with space and arrow keys and leave it with q.

To get a text console to enter the commands you can press <ctrl>+<alt>+<Fx> with Fx one of the function keys and login.

have the same hardware with debian 12
after install the firmware of the 740m could not be loaded.
so download the actual firmware from https://git.kernel.org/pub/scm/linux/ke ... rmware.git, copy the content of the folder amdgpu to /usr/lib/firmware/amdgpu and run update-initramfs -u.

in my case it worked, but sometimes it stucks at boot. i have to boot an older kernel where i had not done update-initramfs, after that i can boot normally.
