Just now I tried the installer on an AMD desktop but the graphical
installer screen stays black. Same on an AMD laptop. After switching
to another TTY, dmesg tells me this:
> [ 11.625264] shepherd[1]: Service host-name has been started.
> [ 11.625839] shepherd[1]: Service user-homes has been started.
> [ 11.629846] shepherd[1]:
> [ 11.630078] [
> [ 11.630230] modprobe
> [ 11.630382] ]
> [ 11.630592] modprobe: FATAL: Module uvesafb not found in directory
> /lib/modules/6.0.10-gnu
>
> [ 11.631734] shepherd[1]: Failed to start maybe-uvesafb in the background.
> [ 15.185776] 0000:04:00.0: Missing Free firmware (non-Free firmware loading
> is disabled)
I tried manually running the modprobe command from
gnu/system/install.scm:
/gnu/store/vh4g56m35wwlfg300s4qafykxjy09511-kmod-29/bin/modprobe uvesafb
v86d=/gnu/store/na24a7653hyf0pghhw9nhfr6mi15v6cz-v86d-0.1.10/sbin/v86d
mode_option=1024x768
Works fine. I can switch back by Ctrl-Alt-F1 and the graphical
installer works.
/run/current-system/kernel/lib/modules/6.0.10-gnu/kernel/drivers/video/fbdev/uvesafb.ko.gz
exists.
So I tried waiting until it exists before modprobe (in the attached
patch). But modprobe still fails in the same way, according to dmesg,
even though the file evidently already existed.
Why doesn’t modprobe find it? Where does it look?
I will try tomorrow to get an strace. The installer worked fine in …
August I believe.

Florian
