[SOLVED] Unclaimed display controller

Greetings!

I installed minimal Devuan Chimaera on my laptop. Running

sudo lshw -C video

leads to the following output:

  *-display

What should I do to enable that display controller?

Re: [SOLVED] Unclaimed display controller

Hi,

You have posted the output of lshw as an image - the font is tiny and I, at least, find it unreadable, so it's hard to help you further.

This is my output of the same command on my PC posted  with code delimiters.

I'm running a AMD B550 motherboard with a AMD Ryzen 5 5600G with Radeon Graphics.

sudo lshw -C video
  *-display                 
       description: VGA compatible controller

       version: c9
       width: 64 bits
       clock: 33MHz
       capabilities: pm pciexpress msi msix vga_controller bus_master cap_list rom
       configuration: driver=amdgpu latency=0
       resources: irq:37 memory:d0000000-dfffffff memory:e0000000-e01fffff ioport:e000(size=256) memory:fcb00000-fcb7ffff memory:c0000-dffff

Can you do the same, please?

Also it would be helpful if you can say what you are aiming for in video,

Hello:

Indeed it is.

From what I can make out, the entry for *-display UNCLAIMED reads:

product: Topaz XT [Radeon R7 M260/265 / M340/360 / M440/M445 / 530/535 / 620/625 Mobile]

This AMD card is supported in Linux since 4.2.

See here:

https://linux-hardware.org/index.php?id … -1028-0643

The OP should also post the brand/model of his laptop because it seems not all work properly.

Best,

A.

No, I had not installed it. But when I did, that controller's got detected:

@rzmv . . . You should be able to edit your original post to remove the image and replace it with text.
