Mageia forum

With Mageia 7 I'm trying to use Drakboot to edit the kernel boot parameters. When I click save I get the error pop-up that the label is already used. This makes it sound like I should change the label so that I have a new entry instead of just editing the existing one. Do I need to delete the entry and recreate it instead of trying to edit it?

What kernel boot parameters do you want to edit in particular, and what boot loader are you using currently ?

On a related note, you may want to have a look at https://wiki.mageia.org/en/How_to_set_u ... el_options

The current boot parameters I have are:

Code: Select all

BOOT_IMAGE=linux root=UUID=356c61f0-146d-4efd-bb0a-2c734554e519 acpi_enforce_resources=lax resume=UUID=1b700e2c-18bd-4be6-b627-9bf9f84617d0 vga=788

Most of that string is left over from an old Mandrivia install. The resume drive hasn't existed in years and I'd also like to scrub the vga=788 part. I didn't see any option to remove the vga, only to change the resolution of it.

What bootloader are you using (e.g. GRUB or GRUB2, as shown on first drakboot screen)?

GRUB with graphical menu.

I believe for the vga=788 part, under Advanced you can only select a different video mode. If you want to remove that, you would need to edit /boot/grub/menu.lst manually if I'm not mistaken.
Although the resume=UUID=1b700e2c-18bd-4be6-b627-9bf9f84617d0 part should be removable, it's contained in the Append: field and you should be able to delete it there.
But I don't have any grub legacy system to confirm whether drakboot works the same with grub legacy.

I can't reproduce the error you describe. On the second drakboot screen, I selected the menu entry I wanted to change, clicked on the Modify button, removed the resume=... in the Append text box, and clicked on the OK button. No errors were reported, and checking /boot/grub/menu.lst, the change was made.

To remove the vga= option, when modifying a menu entry, open up the Advanced dialogue, then in the Video mode drop-down list, select the blank line at the top of the list.

Thank you, I didn't notice the blank line. I still get the pop up, but checking /boot/grub/menu.lst shows that the change was applied.

Do you happen to have two menu entries with the same label? I don't think GRUB would care, so it wouldn't stop it working.

Wow, you're right. I didn't realize there actually was a duplicate until I manually looked at /boot/grub/menu.lst after reading your post. Removed the duplicate and the pop-up went away. Thanks.
