[ubuntu] grub2 and timeout problem

Greetings all:
After I upgraded my Ubuntu from 14.04 to 16.04, there are several problems, one of the is the TIMEOUT variable in grub2 config file is not taking effect, I've set the timeout = 3, but when the grub2 screen came up, the timeout showing at the bottom of the screen is 10s instead of 3, where should I change? Is there any old config file still in the system? This is what I did:

Code:

sudo gedit /etc/default/grub

this is what in my file after change:

Code:

GRUB_DEFAULT=2
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=3
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

when I tried to save the file, it gave me this error message:

Code:

** (gedit:5938): WARNING **: Set document metadata failed: Setting attribute metadata::gedit-spell-enabled not supported

then I did

Code:

sudo update-grub

does the above error has anything to do with timeout not working? How do I fix it?

Let's block ads! (Why?)
