方法1，还是原来的vga=788<br>
编辑 /etc/default/grub ，中的GRUB_CMDLINE_LINUX=”vga=788″<br>
保存以后运行update-grub<br>
但是这样子会显示<br>
vga=788 is deprecated and asks me to use “set gfxpayload=800×600x16;800×600″ before the linux line.<br>
意思就是vga参数已经是建议不要使用了，要用另外一种方法：</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
方法2：<br>
编辑/boot/grub/grub.cfg<br>
找到引导linux那几行<br>
增加 set gfxpayload=800×600x16，注意不要带分号，如下：</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
</p>
<div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
