Ubuntu starter set Mate

1

Hello everyone I am To Fabricio I’m new here and not much of Ubuntu Mate.

my problem is that I need to start by default windows.
I put in the terminal: “sudo gedit /boot/grub/grub.cfg” thinking it would be like ubuntu
so hope I could help some of you thank you very much.

2

After you modified grub.cfg, did you do sudo update-grub ?

3

Yes an grub update is necessary, but you may be looking for /etc/default/grub.

4

I put Fabricio @ PC: ~ $ sudo gedit /boot/grub/grub.cfg
[sudo] password for tofabricio:
sudo: gedit: command not found
tofabricio @ PC: ~ $
and nothing = (

It appears to me :

If you change this file, run ‘update-grub’ afterwards to update

/boot/grub/grub.cfg.

For full documentation of the options in this file, see:

info -f grub -n ‘Simple configuration’

GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=lsb_release -i -s 2> /dev/null || echo Debian
GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash”
GRUB_CMDLINE_LINUX=""

Uncomment to enable BadRAM filtering, modify to suit your needs

This works with Linux (no patch required) and with any kernel that obtains

the memory map information from GRUB (GNU Mach, kernel of FreeBSD …)

#GRUB_BADRAM=“0x01234567,0xfefefefe,0x89abcdef,0xefefefef”

Uncomment to disable graphical terminal (grub-pc only)

#GRUB_TERMINAL=console

The resolution used on graphical terminal

note that you can use only modes which your graphic card supports via VBE

you can see them in real GRUB with the command `vbeinfo’

#GRUB_GFXMODE=640x480

Uncomment if you don’t want GRUB to pass “root=UUID=xxx” parameter to Linux

#GRUB_DISABLE_LINUX_UUID=true

Uncomment to disable generation of recovery mode menu entries

#GRUB_DISABLE_RECOVERY=“true”

Uncomment to get a beep at grub start

#GRUB_INIT_TUNE=“480 440 1”

7

Also, gedit is not installed in Ubuntu MATE, but pluma is. So you can replace “gedit” in those commands with “pluma”

8

I do not understand you mean

9

You mean to put it in the terminal: sudo pluma /boot/grub/grub.cfg

10

Yes, that is correct.

It is already open: Grub.cfg (/ boot / grub) -pluma (as root)
within the file is written:

Unfortunately that’s not the right file to edit. See:

https://help.ubuntu.com/community/Grub2/Setup#Configuring_GRUB_2

You need to change the GRUB_DEFAULT parameter, then update Grub.

Sorry I didn’t realize this earlier.
