前几天安装Ubuntu的时候从官网下载了Ubuntu 16.04.3,安装的时候一直有问题,问题太多就不一一描述了,在百度上搜索了好多关键字,我记得是在某个帖子中看到了有人说16.04.3使用的4.10的内核,4.10内核不支持7代i5的核显,于是重新下载16.04.2版本安装,安装过程一切顺利。
然后用了几天,装了不少软件,然后实现了双显卡的切换 传送门:Ubuntu双显卡切换
切换成使用核显以后,重启一切正常,upgrade了几次后,今天开机突然发现屏幕上一直显示下面这个东西
/dev/sda1: clean, 131838/991232 files, 1193255/3933482 blocks
经过搜索发现,别人都是一会就进入系统了 传送门:/dev/sda1: clean, / files, / blocks,而我一直卡在这里。
然后在grub界面按e,编辑启动参数,去掉quiet
,F10开始引导,然后报出can't request region for resource
。这时候想到,刚才编辑grub的时候内核是4.10的,难道是我upgrade的时候升级了???
重启,选择【Ubuntu 高级选项】,然后选择【Ubuntu,Linux 4.8.0-36-generic】,回车,成功启动系统并进入桌面。
切换成使用独显,重启系统,发现也能进入系统了。
所以我决定改成4.8的内核。
执行grep menuentry /boot/grub/grub.cfg
输出:

initrd /initrd.img-4.8.0-36-generic
}
就好了,然后改一下显示的名称,去除三条echo语句。
但是最好不要对/boot/grub/grub.cfg
进行直接修改,该怎么办呢???
在/etc/grub.d
目录中????
知道的请告诉我
