AMD RX560 on Debian Stretch - Not supported?

[Head_on_a_Stick]

what sort of recovery should i resort to, if the recovery mode does automatically cut me "off the cloud"

For the benefit of others: use the systemd.unit=multi-user.target kernel command line parameter to disable the graphical desktop.

Thanks ,

this seems complicated to me. does this apply also on a VirtualBox?
i would like to add that i did a "fresh install" on a SSD (RyzenPC with dedicated RX560 Graphics) so i am really wondering why this happens. The RX560 is a reformulated RX460 if i understood correctly. Should lead to a graphical environment, if selected, on Debian 10.

+the recovery offers no internet connectivity?
+the DVD installer seems faulty again (hence i resorted to USB > no DVD line is added to sources.list > no internet > no package installs.

Because that card needs non-free firmware to work properly, as has already been explained several times in this thread.

Not unless you install the non-free firmware. So that card isn't supported by the official Debian release but the necessary packages are available from the non-free component of the Debian repositories.

AFAIUI, only a limited number of services are started in recovery mode so the networking services must be excluded. It is certainly possible to connect from the recovery mode though and booting to multi-user.target should leave you with the networking enabled.

Total fail.

Yes, you're not doing well, are you?

Boot with the systemd.unit=multi-user.target kernel command line parameter to disable the graphical desktop, use ifupdown or nmcli to connect then add the non-free component to your sources, update the package database and install the non-free firmware required by your graphics card.

Hello ,

i tried once more to install this (now with Debian-10-Gnome-Live.iso)


where should i enter this "systemd.unit=multi-user.target command line?

If i press "E" @Grub there comes a very long list of commands.

Mode 2, to regain Network-Connectivity:
In recovery mode, the command
"ifupdown" is unknown
and "nmcli" gives no result
and "ifconfig eth0 up" is not working in recovery because "ifconfig" is apparently no longer included since Stretch.

Very smart Debian

Ok, Thanks, now i found out:

i would insert it in line "linux" after "quiet" -

now it is booting into recovery with Internet capabilities again.
but installing

apt install firmware-amd-graphics

solved nothing.

[mrkapqa]

sudo apt-get install firmware-linux-nonfree was missing!


This
systemd.unit=multi-user.target
thing should be somehow made available in recovery mode as an option, that would very much alleviate the process.

[Head_on_a_Stick]

So is it working now?

"ifconfig eth0 up" is not working in recovery because "ifconfig" is apparently no longer included since Stretch.

The ifconfig command was made obsolete quite a while ago and so is no longer included in the stock system.

Code: Select all

# ip link set eth0 up

This
systemd.unit=multi-user.target
thing should be somehow made available in recovery mode as an option, that would very much alleviate the process.

I've included the information in my [FAQ], hopefully people will read that rather than start more threads about this.

EDIT: the rescue mode in the ISO image can be used to get a root shell in the system with a working internet connection.

[mrkapqa]

yes, it is functioning, quite well.

Firmware-Amd-Graphics was not sufficient, Firmware-Linux-Nonfree was needed (too).


I could not tell if it would suffice to install Firmware-Linux-Nonfree.


In any way, this has been a workaround, but i would presume a lot of people are affected by this issue and could be disappointed.
I tried to install a newer Kernel to see if this alone would settle it, but apparently there are none available in the repositories. Testing and Sid shows the same Linux-Image.

The Social Contract and the Debian Free Software Guidelines are considered more important than convenience.

Thanks ,
i wonder how well the free driver development for the Polaris GPU has then become - it is now 3 years since its release more or less - if there is still a "free" driver around ...
i never had such problems with Debian until recently .. so i am still a bit baffled.

I am a bit confused by the wiki here as it says "Open Source Drivers"

https://wiki.debian.org/AtiHowTo


Does Debian not allow to include such "Open Source Drivers" ?

Debian includes the open source AMD drivers but not the non-free firmware. From your linked wiki page:

Firmware

Proprietary, binary-only firmware (aka microcode) was removed from the Debian kernel's radeon DRM driver in linux-2.6 2.6.29-1, to resolve Debian bug 494009. The firmware can be provided by installing the firmware-amd-graphics or firmware-linux-nonfree package.

Without this package installed, poor 2D/3D performance in the radeon driver is commonly experienced. Some GPUs may require firmware to operate the X Window System, or do dual display.

These drivers are open source, while firmwares are not. So Debian ship drivers (for which code is available), while for firmwares (for which code is not available) you need to do something about.

In this case it is enough to enable non-free repo and to install missing blobs... while you are there take a look, maybe you need something more from there
Like maybe CPU microcode updates, etc... these are also blobies and also not installed by default of course.

Like BIOS updates blobies for your mobo, optional sometimes not so maybe you want it maybe don't

The only serious problems i ever had with Graphics or Firmware was with PowerPC Graphics on Powermac G5 when upgrading to Jessie (that concerned Nvidia, mostly).
Also some ATI Graphics had a bit of trouble on Powerbook G4, but that was also more of a singular Graphics Card Line Problem.

Since i run a RyzenPC withouth WiFi or Bluetooth i don't think i am missing something , but thanks for the tip, i still might take a look around to see what is there to learn.
