You can use nano but personally I do everything with gedit both in my regular user account and with sudo. In this case sudo is needed so it would be:
sudo -H gedit /etc/default/grub
Then change:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to:
GRUB_CMDLINE_LINUX_DEFAULT="iomem=relaxed quiet splash"
- Save the file
- Exit
gedit - Run
sudo update-grub - Type
reboot
After rebooting type:
cat /proc/cmdline
You will see your changes in effect. Whether everything works or not is a different story :)
