so i’m trying to update my grub after i installed a new theme

when i do

sudo grub-mkconfig -o /boot/grub/grub.cfg

it says

/etc/default/grub: line 11: Section: command not found

i checked grub and these are the first 11 lines

GRUB_DEFAULT=saved
GRUB_TIMEOUT=5
GRUB_TIMEOUT_STYLE=hidden
GRUB_DISTRIBUTOR="Manjaro"
GRUB_CMDLINE_LINUX_DEFAULT="quiet apparmor=1 security=apparmor resume=UUID=11e0da9a-9c9c-4711-8847-bc08ac54f8c9 udev.log_priority=3g splash vt.global_cursor_default=0"
GRUB_CMDLINE_LINUX=""
# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings:  version 520.56.06


Section "ServerLayout"

what do i do

2

What the? Did you get a xorg config file mixed up with your Grub config file? That shouldn’t be in there.

3

no, it’s my grub, i opened /etc/default/grub and those are the first 11 lines

4

i didn’t add that there by the way it was there when i opened it

5

Maybe you accidentally ran an nvidia tool and told it to write into /etc/default/grub ?

Either way, the references to Xorg / Nvidia should be removed.

Can you paste the entire contents of your default Grub config? It might be even further invalid than the first 11 lines.

What is your partition layout?

lsblk -o name,fstype,size,type,mountpoints

How did you install Manjaro?

What is the sda device?

Did you install another instance of Manjaro?

13

at first installed manjaro on a hard drive while waiting for an ssd

used it for a week then installed manjaro on the ssd when i got it

i still have the other instance encase i needed a linux environment to fix something in my system from it if it broke, because i have a lot of power outages and power went out while i was updating my kernel twice before and i had to reinstall the kernel

14

If that’s the case, seems like you should be fine now?

Did you try rebooting?

15

i’ll try rebooting rn

16

yup it works fine now, thank you mr. winnie :3

To satisfy your own curiosity, what does this reveal?

grep nvidia $HISTFILE | head -n -1

Perhaps you’ll find the culprit as to how nvidia-settings wrote into your Grub config file. :wink:

If it doesn’t yield the command that is responsible for this, then it means one of the following:

  • It was done via the GUI Nvidia Settings panel
  • It was done automatically under-the-hood by a process
  • You ran the nvidia-settings command as the root user
  • You accidentally copied+pasted into your Grub config while you still had Nvidia related things in your clipboard.
