Once installed, restart your computer and done.
非常重要的提醒看下面这段英文,貌似是要重新编译一些驱动?
NOTE: Any drivers not part of the main kernel tree (which of course includes proprietary drivers) must be rebuilt for new kernel versions as internal kernel interfaces may have changed.
假如重启发现你的系统出现问题,请进grub然后高级选择之前的旧内核,然后移除 3.12.4新内核,命令如下
If for some reason this kernel does not work properly for you, restart and boot into Grub -> Advanced -> select previous kernel. Then remove Linux Kernel 3.12.4 via commands below:
代码: 全选
sudo apt-get purge linux-headers-3.12.4-* linux-image-3.12.4-*
