Switching the default kernel via garuda settings gui failed

Issues & Assistance
1

Hello,
I've just installed Garuda Linux some days ago and I tried to switch the default booted kernel from -zen to -tkg-bmq.
While the gui says that the changes which entry to boot from have been applied, the preselected kernel while boot remains the -zen
I can manually select the other one, but that's beside the point of useability.

here is my inxi output:

I am thankful for any advise.

Use the 'Garuda Welcome' app and select the 'Garuda Boot Options' and you should be able to select which kernel to use as default during boot.

3

Those are the steps I took and it returned: applied successfully. But it still boots into the -zen kernel.

4

Sounds like an issue with the Garuda Boot Options GUI. Maybe one of the Garuda devs can weight in.

I think that kernel orders or defining new defaults have some known bugs (if you search in the forum you'll find several topics about it).
You should edit /etc/default/grub and change GRUB_DEFAULT=0 (which is the first line you see in the GRUB) to e.g. GRUB_DEFAULT=1 (second line) or whatever else, also in sub-menu, I think you can use e.g. GRUB_DEFAULT="1>2" (third line in second line submenu).
You should also comment out GRUB_SAVEDEFAULT, e.g.

#GRUB_SAVEDEFAULT=true

Pay attention, sometimes some parameters (e.g. GRUB_DEFAULT) might appear more than once in the grub file).
Then update-grub of course.

PS: welcome!

From what I had read previously, it sounded like enabling GRUB_SAVEDEFAULT had some sort of issue with btrfs. and since I didn't want to wreck my system I left this setting untouched.

I had disabled submenues to ease in debugging why it won't set properly.
Thanks for the hint with the "1>2". I'll give this a try.

Yes, I'm not a developer nor a technical experet, but I remember this should be all something related to grub with btrfs, nothing specific to the Garuda Assistant...
Anyway the editing above should work, I've been using it for a long time, pointing to both main menu and sub-menu.

Thank you filo, for the quick reply. I successfully set the right default now. It works, but in my humble opinion doing it that way defeats the purpose of having a GUI for the same task.

I mean the graphical way should yield the same result in the end.
