Mouse pointer freezing periodically for short time

Recently I've switched from Nvidia proprietary drivers to Nouveau because of youtube videos playback issues. The Nouveau driver runs smoothly, the GPU temperature dropped from 72° to 66° and youtube playback is smoother. Despite of this there was one small issue I've noticed. The mouse pointer was freezing for short, random periods about each 10 seconds.

After couple of hours googling and debugging this issue I found a solution:
-to solve it until next reboot (as root): echo N > /sys/module/drm_kms_helper/parameters/poll
-to solve it definitely (as root): echo "options drm_kms_helper poll=N" >> /etc/modprobe.d/modprobe.conf

Note: check if modprobe.conf is applying the change with cat > /sys/module/drm_kms_helper/parameters/poll, if not, set the echo command in the /etc/rc.local file.
