Ubuntu 15.10 - Xorg and Compiz high cpu / memory usage.

My Personal laptop suddenly became damn slow, started debugging to analyze the issue. With the help of top command identified Xorg and Compiz (more than 20 %)are using more CPU usage.

Googling helped to decrease Compiz process below 10%. Below command helped.

sudo apt-get install compizconfig-settings-manager


Still Facing issue with Xorg now and then. Temporary fix restart of laptop once or twice is resolving the Xorg high performance issue. Looking for a permanent fix. Doing Research on that, I will update this post, once I resolve this issue/bug.

Xorg CPU usage
My CPU has two cores, where one core is below 10 % usage and another CPU core is more than 90 %. I guess this is due to Xorg CPU usage in above picture, when Xorg is not using more CPU, then CPU two cores are below 10%.


Guys, if you come across any working solution please let me know through comments. I appreciate it.
