I now have 4 screens working on this machine, 2 connected to the Radeon
card: HDMI-1-1 and VGA-1-1, and the built-in Intel graphics has HDMI-1 and
VGA-1.

xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x8c cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 3 associated providers: 1 name:modesetting
Provider 1: id: 0x46 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 4 outputs: 3 associated providers: 1 name:ATI Radeon HD 5450 @ pci:0000:01:00.0

Showed both cards from the beginning (after installing
firmware-amd-graphics), but only after I ran this:

xrandr --output HDMI-1-1 --auto --right of HDMI-1
xrandr --output VGA-1-1 --mode 1280x1024 --right of HDMI-1-1

Did the monitors connect and were usable.

I had done this previously, with no error message or any visible sign
that it did anything, so it might or might not have been necessary.

xrandr --setprovideroutputsource 1 0
xrandr --setprovideroffloadlink 1 0

So, finally success.  Next: install mythtv.
