[Hardware] [SOLVED] AMD Ryzen 7 6800H GPU can't change resolution in Debian 11.5

[dannychen]

Hi All，

I just bought a new laptop with the ADM Ryzen R7 6800H CPU.
There's an integrated gpu card in this CPU.
Please see below AMD site link for CPU,GPU detail：
https://www.amd.com/en/products/apu/amd-ryzen-7-6800h

Issue：
I installed Debian 11.5 in this new laptop.
However, I can't utilize xrandr to change resolution.
It's stick to 2560x1600@93.00.

Maybe it's a new CPU,Debian 11.5 doesn't support well?

Appreciate your help.

I think you need to get radeon loaded and not vesa.

Please post output of

Fwiw when I got my last laptop (Ryzen 9 5900hx) I had to use Testing (Bookworm) in order to get everything working properly, I would imagine it would most likely be your best course of action too, but with the (obvious?) warning that it is TESTING and may cause issues that you will need to spend some time diagnosing/fixing/reporting. Although with that said I have found no issues so far and it has been around 6 months or so, but ymmv.

I would also imagine that using backports for kernel and graphics packages might also do the trick but at the time it didn't have a new enough kernel for me so I went straight to testing.

Hi Frank,
Thanks for your reply.

You need to install firmware-amd-graphics and firmware-realtek. Probably amd-microcode as well.
That should satisfy your firmware errors but no guarantee it will fix everything for such new hardware which is more recent than Debian Bullseye.

I just updated to the Bookworm ,it seems still can't change the resolution.
And I installed the firmware-realtek. The realtek error was fixed.

Issue solved as below steps:
1, Upgraded to the Bookworm.
2, Installed the firmware-amd-graphics.

Noted, can't work even install the firmware-amd-graphics in the 11.5.

Thanks all for your kindly help.

As we suspected, your hardware is too new for Bullseye. Bookworm is not really considered an upgrade as it is designated Testing, a development version. It will have more bugs than Stable and may break occasionally. Don't forget to update/upgrade it regularly, at least once a week. Don't allow the upgrade if it proposes to remove many essential packages, just wait and try another day.
