Which modules to include in the --module parameter of the grub-install command

[Arbiel (gmx)]

Hi

I'm trying to help a user who experiences difficulties to boot a Ubuntu
distribution. grub does not display any message on the screen even when
entering the rescue mode (in a test, he suppressed the configuration
file, but got no message neither). As nothing is wrong in the
bootinfoscript's report, and as his PC is fitted, beside the motherboard
video processor, with two NVidia GTX580M video cards, I believe the
issue is video and the solution is to use the --module=MODULES parameter
of the grub-install command.

However, I have no idea of the required modules to include to have grub
run and the pieces of information I found at
"http://www.linux.org/threads/understanding-the-various-grub-modules.7535/";
are not explicit enough for me to poke around the right ones.

As the PC is BIOS based (no UEFI), my tentative list of modules would be
915resolution
acpi
ahci
all_video
ata
biosdisk
bufio
chain
cpio
cpuid
disk
drivemap
echo
ehci
exfat
ext2
file
font
iorw
linux
loadenv
mmap
msdospart
normal
ntfs
part_msdos
pata
pci
scsi
serial
terminal
uhci
usb
vga

Is this list the right one ?

Thank you for any help.
