一行的尾部是空格的话无法加下划线

https://blog.csdn.net/civilman/article/details/43229935

我使用这种方式解决了

方法1:在最后插入一个非间断性空格(Ctrl + Shift + Space)即可。

方法2:使用 Tab 键并将下划线格式应用于制表符

office 激活信息查看

安装目录下,office14(数字) cmd
cscript ospp.vbs /dstatus

linux ubuntu 无法调节亮度

https://www.cnblogs.com/xu-neal/p/3940393.html

sudo vim /etc/default/grub
在打开文件中找到

GRUB_CMDLINE_LINUX=””

改成

GRUB_CMDLINE_LINUX=”acpi_backlight=vendor“

改好后保存即可

sudo update-grub
终端输入代码:

sudo vim /etc/rc.local

在打开文件里增加一句(加在exit 0之前)

echo 500 > /sys/class/backlight/intel_backlight/brightness

然后保存即可
