对不起，我的英语不好
我的问题是 Lubuntu 16.04 中的屏幕撕裂，我的 GPU 是 Intel HD 图形，我安装了 compton，这个命令对我有帮助， 但我想自动启动 compton，所以我在互联网上搜索这个。我通过添加此行来$ compton -b --vsync opengl
编辑文件 ，但它不起作用，有人能帮助我吗？/etc/xdg/lxsession/Lubuntu/autostart@compton -b --vsync opengl
$ which compton
/usr/bin/compton
$ sudo systemctl status mycompton.service

您可以使用一个简单的systemd服务来自动启动它：
创建服务文件：
sudo nano /etc/systemd/system/mycompton.service添加如下配置：
[Unit] Description=compton autostart script After=network.target [Service] Type=forking ExecStart=/usr/bin/compton -b --vsync opengl Restart=always [Install] WantedBy=multi-user.target启动并启用 compton 服务：
sudo systemctl start mycompton sudo systemctl enable mycompton检查状态：
systemctl status mycompton停止它：
sudo systemctl stop mycompton
笔记：
如果与我自己的输入不同，则/usr/bin/coompton用的结果替换该行。which compton
