I performed a minimal install of Debian 12 Bookworm a few weeks ago, and it's been working great. I skipped installing a DE at the time and have been using the machine entirely headless via SSH without issue.
I just installed a GPU, and attempted to install a DE, but I can't seem to get anything to actually render to that GPU. I've confirmed both the GPU and monitor work on other installs. I believe I'm just missing a key step in moving from a minimal install to a working Desktop Environment.
The Issue
Whenever I boot, the monitor plugged into my discrete GPU stays in its power-save state. Once the kernel loads, the monitor exits its power-save state, turns its backlight on, but the screen remains completely blank (no text cursor, no mouse cursor, and certainly no greeter/login-screen or DE). I am, however, able to SSH into the machine just fine.
The Question
How do I get KDE up and running on this machine with this AMD Radeon X300 SE GPU?
What I've Done
In the spirit of trying to simplify the debug process, here's a few relevant outputs:
The card is correctly showing up on the PCIe bus (see "e1:00" in output below)The kernel appears to be able to correctly detect and probe the card (see "Device-1" in output below).
The kernel is also correctly detecting the monitor plugged into the card (see "Monitor-3" in output below).Similarly, we can also see quite a bit more info about the card (see "*-display:0" in output below):Lastly, the card also appears to be detected properly based on relevant DRM output from dmesg:Any guidance on how I can get KDE up and running with GPU on top of a properly-running minimal install would be welcome.

What I've Done
- Started with a Minimal Install from the netinst .ISO
- Ensured /etc/apt/sources.list contains the correct repositories (i.e., main, contrib, and non-free-firmware):
deb http://deb.debian.org/debian bookworm main contrib non-free-firmwaredeb-src http://deb.debian.org/debian bookworm main contrib non-free-firmware
- Installed AMD-related firmware, drivers, packages, etc.:
apt-get install firmware-amd-graphics amd64-microcode xserver-xorg-video-radeon
- Installed KDE:
apt-get install plasma-desktop plasma-nm
