Hi i use ubuntu 16.04 and i install Liquorix Kernel step by step from site https://liquorix.net

1) i install keyring
:: Code ::
apt-get install liquorix-keyring

2) add Liqorix to source list
:: Code ::
sudo echo "deb http://liquorix.net/debian sid main" > /etc/apt/sources.list.d/liquorix.list

3) update source list and install liquorix 64 bit
:: Code ::
sudo apt-get update

:: Code ::
sudo apt-get install linux-image-liquorix-amd64 linux-headers-liquorix-amd64

after reboot i check uname -r and everting it`s ok i have installed liquorix kernel and now i type:
:: Code ::
cat /sys/block/sda/queue/scheduler
noop [deadline] cfq bfq


so bfq is supported and now i want change it from default deadline to bfq so i edit and update grub
:: Code ::
gksudo gedit /etc/default/grub

change one line from:
:: Code ::
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to:
:: Code ::
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash elevator=bfq"

:: Code ::
sudo update-grub2

but after reboot i have still deadline by default
:: Code ::
cat /sys/block/sda/queue/scheduler
noop [deadline] cfq bfq
