Yes, I agree.  It would need a way to make a custom GRUB menu entry that
refers to a Guix System generation, and adding that feature is
complicated because it best worked for other non-GRUB bootloaders too.
If it were added, “safe video” could be described in the same place.

[Message part 4 (text/plain, inline)]

Hello,

I'm trying to install Guix system on an i386 laptop. When the installer
should reach the GUI, only a black screen is displayed.

I tried to boot by editing Linux boot parameters in GRUB and set
`nomodeset` and removed `quiet`. Now without `quiet` I saw the following
messages before the black screen:

```
intelfb: Version 0.9.6
intelfb: Cannot reserve FB region
```

Then I tried `nomodeset video=uvesafb` Linux parameters and the GUI now
rendered. I don't know if these work as a global workaround for other
machines, should they be documented in the installation instructions?
