設定ubuntu字元界面分辨率劄記

  On x86 systems, the kernel will be booted using the 32-bit boot

     protocol.  Note that this means that the `vga=' boot option will

     not work; if you want to set a special video mode, you will need

     to use GRUB commands such as `set gfxpayload=1024x768' or `set

     gfxpayload=keep' (to keep the same mode as used in GRUB) instead.

     GRUB can automatically detect some uses of `vga=' and translate

     them to appropriate settings of `gfxpayload'.  The `linux16'

     command (*note linux16::) avoids this restriction.
