Alta carga ociosa do Xorg

Question

Alta carga ociosa do Xorg

2

Quando tenho alguns programas em execução no KDE e não faço nada, ainda tenho Xorg e plasmashell, cada um com 11% de um núcleo de CPU. kwin_x11 leva outros 6%. Juntamente com outros trabalhos em segundo plano, entro na região de 12% do total de carga do sistema em ocioso. Isso significa que o ventilador do meu laptop nunca desce para o nível mais baixo.

Como posso descobrir o que causa essa carga quando aparentemente nada está acontecendo?

strace

strace no Xorg

Eu anexei strace a Xorg como root e deixei rodar por cerca de três segundos. Neste tempo eu recuperei 8273 linhas de saída. Parece ser uma repetição do seguinte bloco:
