Why always resee ~/.snap folder?

https://askubuntu.com/questions/1079203/why-is-gnome-system-monitor-on-18-04-installed-as-a-snap-by-default

$ sudo snap remove gnome-system-monitor
$ sudo apt install gnome-system-monitor

https://askubuntu.com/questions/1039411/how-can-i-replace-snap-application-such-as-gnome-calculator-with-a-deb

# remove all snap packages except core and core18
$ sudo snap remove `sudo snap list | cut -d " " -f 1 | tail -n 2 | grep -v 'core' | tr '\n' ' '`
# Then install their .deb counterparts with:
$ sudo apt install gnome-calculator gnome-characters gnome-logs gnome-system-monitor
#  uninstall the whole Snapd ecosystem from your computer with:
$ sudo apt purge snapd squashfs-tools gnome-software-plugin-snap

[Durant35]

Topicons plus支持Wine等图标显示

# 安装tweak-tool,用于定制化桌面
$ sudo apt install gnome-tweak-tool
$ sudo apt install gnome-shell-extension-top-icons-plus
# 重启后，打开tweak-tool->Extensions勾选Topicons plus，并可配置Top Center/Right...
