Ubuntu/ LMDE 安装后进行一些设置:
1.设置主板时间为本地时间，默认为UTC时间，与Windows不同，如果双系统，时间有时差
sudo timedatectl set-local-rtc true
2.移除无用软件
sudo apt remove --purge snapd apport rsyslog deja-dup orca shotwell aisleriot gnome-todo gnome-calendar gnome-mahjongg gnome-online-accounts gnome-mines gnome-sudoku gnome-logs gnome-font-viewer gucharmap baobab thunderbird ibus-mozc seahorse usb-creator-gtk unattended-upgrades ubuntu-advantage-tools fonts-arphic-ukai fonts-arphic-uming
sudo apt remove --purge apport rsyslog hexchat redshift thunderbird transmission-gtk onboard gnote gnome-logs gnome-font-viewer gucharmap timeshift baobab cryptsetup cryptsetup-initramfs brltty fonts-arphic-ukai fonts-arphic-uming
sudo apt install plymouth-themes
lmgrd: ln -s /lib/x86_64-linux-gnu/ld-2.28.so ld-lsb-x86-64.so.3
3.安装常用的软件程序
sudo apt install csh flashrom vim vim-gtk3 tree android-tools-adb android-tools-fastboot git subversion ssh cmake gcc g++ gparted unrar rar p7zip dos2unix minicom picocom tftp device-tree-compiler u-boot-tools bison flex mtd-utils libncurses5 libncurses5-dev fxload sdcc winbind gdebi libusb-1.0-0 libusb-1.0-0-dev librxtx-java libx11-6:i386 libc6-dev-i386 libpng16-16:i386 libfontconfig1:i386 libjpeg62:i386 libtiff5:i386 libxau6:i386 libxext6:i386 libsm6:i386 libxi6:i386 libxrender1:i386 libxrandr2:i386 libxft2:i386 libncurses5:i386
sudo apt install verilator iverilog gtkwave ngspice octave octave-communications octave-signal octave-symbolic
4.grub配置
GRUB_TIMEOUT_STYLE=hidden
GRUB_CMDLINE_LINUX="net.ifnames=0"
5.配置APT，可以安装libpng12等老版本的软件包
vim /etc/apt/sources.list.d/official-package-repositories.list
deb http://mirrors.ustc.edu.cn/linuxmint debbie main upstream import backport
deb http://mirrors.ustc.edu.cn/debian/ buster main contrib non-free
deb http://mirrors.ustc.edu.cn/debian/ buster-updates main contrib non-free
deb http://mirrors.ustc.edu.cn/debian/ buster-backports main contrib non-free
deb http://mirrors.ustc.edu.cn/debian-security buster/updates main contrib non-free
deb http://mirrors.ustc.edu.cn/debian/ jessie main
6.如果安装的是Gnome桌面环境，可以通过gsettings set org.gnome.desktop.app-folders folder-children [''] 来删除应用程序菜单下的目录。
