GRUB_CMDLINE_LINUX

• disable opensource's nvidia driver for installed closesource one:rd.driver.blacklist=nouveau , modprobe.blacklist=nouveau
• rd.lvm.lv=lvm/mylv: boot up from which lvm logic volume
• acpi_backlight=native: laptop backlight control by native bios, =vendor just don't work for me
• splash: grub select GUI's background image for DIY
• quiet: 这个参数会减少系统启动时的消息输出。当你在 grub 配置文件中设置了 quiet 参数，系统在启动过程中不会显示大部分的启动消息。这可以使启动过程看起来更加干净，但如果出现问题，可能会更难进行故障排除。
• rhgb 这是 Red Hat Graphical Boot 的缩写，这个参数会启动一个图形界面来显示系统启动进度。这个参数通常在 Fedora、CentOS 和其他基于 Red Hat 的发行版中使用。

  I hate this, i don't know what's wrong when boot up failed 😦
