Using XFCE solves the problem. Seems that it's caused by compiz when using Unity.

We have the high CPU usage and flickering mouse pointer on laptop screen issue also without metacity. Using Ubuntu 16.10. I have two 27" screens connected on the DELL 3100 docking station. The latest Ubuntu driver is installed.
Here is a link to the htop command's output from my laptop: ![]() Another issue is the very low frame rate. See the report from the glxgears program below. ![]() Last edited by jepster; 10-21-2016 at 03:12 PM. |

I get an extremely high FPS reported from glxgears:
Code:
$ glxgears Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate. 303 frames in 5.0 seconds = 60.553 FPS 1203 frames in 5.0 seconds = 240.384 FPS 8173 frames in 5.0 seconds = 1634.242 FPS 9915 frames in 5.0 seconds = 1982.991 FPS 8718 frames in 5.0 seconds = 1743.354 FPS 8002 frames in 5.0 seconds = 1600.181 FPS 8554 frames in 5.0 seconds = 1710.762 FPS ![]() I'm running xfce... |
