Solução para cairo-dock sem carregar

As vezes estamos utilizando o cairo-dock e por ventura não carrega mais por motivos de bugs no software, como por exemplo trocar de tema e não carregar/abrir e apresentar erros no cairo-dock como este abaixo:

$ cairo-dock -o

Cairo-Dock was not built with EGL support
warning :  (/build/cairo-dock/src/cairo-dock-core-3.4.1/src/implementations/cairo-dock-glx.c:_initialize_opengl_backend:129)  
  couldn't find an appropriate visual, trying to get one without Stencil buffer
(it may cause some little deterioration in the rendering) ...

Solução

Remover diretório de configurações do cairo-dock e depois eniciar o software novamente:

rm /home/$USER/.config/cairo-dock -f

Também você pode fazer um backup dos temas do cairo-dock e repor novamente depois de ter iniciado o cairo-dock novamente.
