#1011450 — Bug#961590: d-i: add 'panfrost' to 'fb-modules' so graphical installer can be used

Package: linux
Severity: important
Tags: d-i

Devices with Mali gpu can use 'panfrost' driver to provide working
framebuffer. And then Debian installer can be run on screen instead of
serial console.

But 'panfrost' module is not available when d-i starts ;(

So please include 'panfrost' in 'fb-modules' udeb.

Panfrost shouldn't be necessary for a working framebuffer. On my 
rk3399-gru-kevin, rockchipdrmfb handles that and d-i runs on the screen 
just fine.

Which device are you having this issue with?

RockPro64 does not enable screen at all. And there are no DRM modules in
netinstall image [1]:

~ # cd /lib/modules/5.6.0-1-arm64/
/lib/modules/5.6.0-1-arm64 # find . -name *drm*
/lib/modules/5.6.0-1-arm64 #

There are two initrds in that iso, 'install.a64/initrd.gz' doesn't have 
drm modules, but the 'install.a64/gtk/initrd.gz' one has them. Can you 
try booting the gtk one? If you boot to GRUB, 'Graphical Install' should 
be using that.

However, that image is currently broken due to a kernel version mismatch 
and won't actually install, try the weekly build instead:

And that's plain wrong.

I want to run D-I on my monitor. Nevermind is it text mode one or gtk
one. My board does not require serial console to boot as I have
graphical output in U-Boot and can control it using USB keyboard.

And I prefer text mode D-I over gtk one.

Thanks. Works like a charm.

I agree they should be included, so I'm changing bug metadata to that 
(hopefully correctly).

> And I prefer text mode D-I over gtk one.

You can also add DEBIAN_FRONTEND=newt to the kernel cmdline to force 
that in the gtk builds.

Haven't really tested, but this change should be enough:
