When this happens, i can login from another PC via SSH. Display on screen stays same, won’t update, i can move mouse, but click won’t work.

I was using default Nvidia Driver version 367.57 provided by Ubuntu. Because of this error, i upgraded to latest Nvidia driver from graphics-drivers PPA (version 375.26). But this error still happens at times.

I was able to generate bug report with nvidia-bug-report.sh, i don’t see an option to attach it here, so uploaded it at

Anyway to fix this error ?
