Codename: precise
grub-install (GRUB) 1.99-21ubuntu3.1
I tried the more elegant way: I found some problems identifying the correct conditional switch and what I had is that I wasn't able to get the menu even if I press every key on the keyboard (SHIFT, ESC, etc.)
My 30_os-prober looks like this

Dareus,
For GRUB 1.99, I changed line 29 of /etc/grub.d/30_os-prober:
I added these lines to the bottom of /etc/default/grub:make_timeout () {
if [ "x${found_other_os}" = "x" ] || [ "x${GRUB_FORCE_HIDDEN_MENU}" = "xtrue" ] ; then
Save both files and update-grub.GRUB_FORCE_HIDDEN_MENU="true"
export GRUB_FORCE_HIDDEN_MENU
On my machine the system no longer displays the menu.

Back to Xorg...
Retired.
Ok, I had modified the wrong block
Anyway, my menu is not showing now on boot but I can't get it to appear using SHIFT or any other key!
The format of the 30_os-prober script makes the 'timeout' section appear to be independent of whether another os is found, but it is.
To correct this, in the same section you just modified, place the following immediately after the timeout funtion:
This should enable the SHIFT and ESC keys.make_timeout () {
if keystatus; then
if keystatus --shift; then
set timeout=-1
else
set timeout=0
fi
else
if sleep$verbose --interruptible 3 ; then
set timeout=0
fi
fi
if [ "x${found_other_os}" = "x" ] || [ "x${GRUB_FORCE_HIDDEN_MENU}" = "xtrue" ] ; then
I've never understood why this feature was placed in the 30_... script and not the main script.

are you sure this line is correct?
I get an error when running update-grubCode:if sleep$verbose --interruptible 3 ; then
My 30_os-prober looks like this:

I'm really puzzled...
1. I found in the same file many lines reporting the sleep$verbose thing
2. I removed $verbose but update-grub keeps reporting there's the error (same message above)
3. Removing the lines you suggested me to add let update-grub not to show any error (finally something that works as expected )
4. Syntax higlighting is really weird in that file (wrongly highlighted parts alternate with right ones)
In short, removing $verbose did not the trick for me
That's because I keep confusing you.
I've slowed down, called up Grub 1.99's 30_os-prober and found the problem.
The section I quoted isn't really run in the 30_ script. It's copied to the grub.cfg file, so the CAT/EOF instructions need to be included in the paste operation.
So the final result should look like this:
Save and update-grub.make_timeout () {
cat <<EOF
if [ "x\${timeout}" != "x-1" ]; then
if keystatus; then
if keystatus --shift; then
set timeout=-1
else
set timeout=0
fi
else
if sleep$verbose --interruptible 3 ; then
set timeout=0
fi
fi
fi
EOF
if [ "x${found_other_os}" = "x" ]|| [ "x${GRUB_FORCE_HIDDEN_MENU}" = "xtrue" ] ; then
Back to Xorg...

First of all let me thank you again for your help in solving my problem.
I did what you said but I still wasn't able to get the menu.
But please, take a look at my script (posted a few messages above): after the make_timeout function declaration there's the block you made me add (now updated to the latest version you suggested), but a few lines down, 12 to be precise, BANG! those lines were already there! And unfortunately didn't work...
