I'm looking for something that doesn't involve web browsers, something I
can use when X doesn't work, or always.

I used that page to find one package I want:
<https://packages.debian.org/search?keywords=firmware-amd-graphics&searchon=names&section=all&suite=buster-backports>

What I haven't found is anything to explain how to translate it into any
apt* command.

Worse, I haven't found anything that makes it clear to me whether a Buster
user needs to configure

	deb http://ftp.debian.org/debian buster-backports main
or
	deb http://ftp.debian.org/debian bullseye-backports main

in sources.list.

What I'm looking for is the closest approximation of openSUSE. Assuming
appropriate repo is configured, I get everything I want there this way:

	# zypper se -s amdg | egrep -iv 'debug|32bit|src|i586'
...
S  | Name                           | Type       | Version             | Arch   | Repository
---+--------------------------------+------------+---------------------+--------+-----------
i  | libdrm_amdgpu1                 | package    | 2.4.100-lp151.264.1 | x86_64 | X11XOrg
v  | libdrm_amdgpu1                 | package    | 2.4.97-lp151.2.3.1  | x86_64 | Update
v  | libdrm_amdgpu1                 | package    | 2.4.97-lp151.1.1    | x86_64 | OSS
i  | xf86-video-amdgpu              | package    | 19.1.0-lp151.64.2   | x86_64 | X11XOrg
v  | xf86-video-amdgpu              | package    | 18.1.0-lp151.1.3    | x86_64 | OSS

To replace the standard package with the newer one in the configured
optional repo, this is the way that comes to mind:

	# zypper in xf86-video-amdgpu-19.1.0

Surely Debian has something roughly or even closely similar. I'm just
short of Google-fu discovering it.
