1、单指单击、双击触摸板，相当于鼠标左键的功能
== 双指操作 ==
#相当于鼠标右键，弹出选择菜单
#双指同时向上/下划，实现屏幕的滚动，相当于鼠标的滚轮一样
#双指同时向左 / 右划滑，用于浏览图片时，向左或者向右划图片的功能
#双指同时向对角划开 / 缩合 ，实现放大或者缩小当前的图片 / 页面
#
==三指操作 ==
#三指单击触摸板，弹出小娜搜索框
#三指同时向上划，三指同时上划，弹出多任务界面，相当于快捷：win+Tab
#三指同时向下划，当前所有窗口最小化，显示桌面
#三指同时向左/右划，实现快速切换任务程序，相当于快捷键：Ait+tab

<pre>

或者直接拿出 电源管理器到 托盘就行了 右键就有了 

cat  /sys/class/backlight/intel_backlight/brightness

ubntu 18.04 is 7200

直接打开 redshift

 xgamma -gamma .7

  sudo apt install tlp tlp-rdw  tp-smapi-dkms acpi-call-dkms linux-cpupower

终端输入代码:
    
sudo gedit /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

然后升级grub：
    
sudo update-grub

重启之。。。按FN就能调节了

0. 确保Debian能够联网

1. apt install x-window-system-core gnome-core  #安装最基本的gnome图形相关软件
systemctl set-default graphical.target //设置成图形模式

2. init 6 #设置系统为图形界面启动，该命令执行后系统会重启

3. 设置系统可以root登录

     1） 修改/etc/gdm3/daemon.conf文件，在[security]下增加一行AllowRoot = true

     2）修改/etc/pam.d/gdm-password文件，注释掉auth required pam_succeed_if.so user != root quiet_success

     3）重启系统后，即可使用root登录。

=HiDPI=
手上用的就是 1080p 的 XPS15。
是这样的，用 1080p 需要非整数倍缩放（或者直接不缩放看小字体，如果你视力够好的话），用 4K 就是整数倍缩放（据一朋友所说 2x 刚刚好）。大多数的 DE 非整数倍缩放都有 bug，在 UI 不知道哪里就会出来一条突兀的缝，或者哪里的布局就乱了。
至于 Windows …… Windows 的 HiDPI ？有这东西吗？


1080P 如何算   xps13   is  192
Re: best DPI setting for XPS 13 9370 with 4k display?

sqrt(3840**2 + 2160**2) / 13.3 = 331 PPI


==config==
<pre>xps13 7390 kali2020

xrandr --dpi 180



Xft.dpi: 160.0

xrdb -merge ~/.Xresources


sudo dpkg-reconfigure  console-setup

===firefox===
 
Enabling the high DPI mode in Firefox is actually pretty simple, it is just a matter of setting the layout.css.devPixelsPerPx value in about:config to a value of 2 (i.e. double the size).

 about:config  --> layout.css.devPixelsPerPx   我试了一下  1.5刚刚好 反正 2太大  小一点点就行了

安装前准备
在安装linux前，有些BIOS选项需要修改下设置，开机按F2进入BIOS，

    Disable Secure Boot. BIOS > Secure Boot > Disabled
    Change RAID to ACHI. BIOS > System Configuration > SATA Operation > RAID to ACHI
    第一项设置禁止安全启动，让Linux可以启动。第二项改硬盘模式为ACHI，让Linux能够检测到NVME SSD，据说修改后Win10会因为驱动出现问题， 要用win10 先忙改bioss 回  raid就行了 。
