I cannot disable os-prober MX23 [Solved]

[Byteria]

Installed MX Linux 23 "Libretto" yesterday, then added to /etc/fstab the line /home from previous installation (MX 21) in order to keep previous user's configurations, and MX23 is working fine.

The only problem I have found so far, is that I cannot disable os-prober, anyway.

I did try "MX Tools >> Boot Options", , both "Yes" and "No", but it didn't disable os-prober.

In /etc/default/grub, I have set GRUB_DISABLE_OS_PROBER=true, then GRUB_DISABLE_OS_PROBER="true".

I have also edited /etc/default/grub.mx-defaults, and then renamed it to grub.mx-defaults.txt

Then, in /etc/default/grub, I have disabled all this block, still without results:

Code: Select all

# GRUB_DISABLE_OS_PROBER=true
# if [ -e /etc/default/grub.mx-defaults ]; then
#      .  /etc/default/grub.mx-defaults
# fi
# GRUB_DISABLE_OS_PROBER=true

Something more, that I could try, in order to disable os-prober?

You might want to start your own thread so it can be seen more easil@Byteria

[Eadwine Rose]

Topic split off. @Byteria your topic is here.

[BitterTruth]

Are you doing sudo update-grub afterwards? MX Boot options should do it automatically though

[dolphin_oracle]

os-prober is enabled by default, so

Code: Select all

GRUB_DISABLE_OS_PROBER=true
# if [ -e /etc/default/grub.mx-defaults ]; then
#      .  /etc/default/grub.mx-defaults
# fi

should do it I think.

[BitterTruth]

Please post your /etc/default/grub file if you can.

Please post your /etc/default/grub file if you can.

It is so, now:

# if [ -e /etc/default/grub.mx-defaults ]; then
#      .  /etc/default/grub.mx-defaults
# fi
# GRUB_DISABLE_OS_PROBER=true

I may suggest this:
Return the changes you made ( or may be keep them):
and run on the konsole this

Code: Select all

sudo debconf-set-selections <<<"grub-pc grub2/enable_os_prober boolean false"

followed by:

Code: Select all

sudo update-grub

would it still run os-prober?
Please try the above first and let us know, wehther this wokred.

Also after the above changes, you can revert the changes,
and try the "classical" way of disabling os-prober, which I think still works on Debian/bookworm,
which is just this:

Code: Select all

sudo chmod -x /etc/grub.d/30_os-prober

Please also let us know whether the classical way works for you.
Thanks

os-prober is enabled by default, so

Code: Select all

GRUB_DISABLE_OS_PROBER=true
# if [ -e /etc/default/grub.mx-defaults ]; then
#      .  /etc/default/grub.mx-defaults
# fi

should do it I think.

I think we may adjust something here, b/c if grub2/enable_os_prober is set to true
os-prober would still run.
Suggest we tweak our os-prober adjusments a bit,
A)* so it will always enable/disable os-prober run depending on the debconf settings are true/false.

and
B)* maybe we adjust the comments a bit if the user really wants to tweak by himself

and
C)* we should consider to keep the current grub-live file in sync with /etc/grub.d,
which currently is not in resp. to os-prober (may be after A and B). Otherwise user installed from snapshot,
may wonder about this different ways of disabling os-prober.
