我已经申请
$ gksu gedit /etc/default/grub
代码:如果您更改此文件,请update-grub
随后运行以更新
/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="acpi_backlight=vendor"
保存并关闭 gedit,下一步:
sudo update-grub
sudo reboot
并且没有任何变化我已经安装了 Ubuntu 13.04 amd 64 帮助!
