Auto iniciar compton no Lubuntu 16.04

Question

Desculpe pelo meu mau Inglês Meu problema é tela rasgando em Lubuntu 16.04, minha GPU é Intel HD gráfico Eu instalo compton e este comando me ajuda %código% Mas eu quero auto iniciar o compton, então eu pesquiso na Internet por isso. Eu edito o arquivo $ compton -b --vsync opengl adicionando esta linha /etc/xdg/lxsession/Lubuntu/autostart Mas isso não funciona, alguém pode me ajudar?

$ which compton
/usr/bin/compton

$ sudo systemctl status mycompton.service

Answer 1

Você pode usar um serviço systemd simples para iniciá-lo automaticamente:

1. Crie um arquivo de serviço:

   sudo nano /etc/systemd/system/mycompton.service
   

2. Adicione as seguintes configurações:

   [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
   

3. Inicie e ative o serviço de computador:

   sudo systemctl start mycompton
   sudo systemctl enable mycompton
   

4. Verifique o status:

   systemctl status mycompton
   

5. Pare com:

   sudo systemctl stop mycompton
   

Nota:

Substitua a linha /usr/bin/coompton pelo resultado de which compton , se diferente da minha própria entrada.
