Public bug reported: I have a tri-monitor setup, two monitors going off of a GPU (Nvidia GTX 650 TI Boost Edition, MSI version so overclocked) and the third going off of Integrated Graphics on my 4670k intel CPU. On the two monitors using the GPU, the mouse has terrible flashing and flickering, and sometimes it sometimes completely disappears. However, on the monitor using the Intel Integrated graphics, it works fine and I have no problems. I've done some testing, and on 14.04 the entirety of X server works for a bit, then crashes completely after a few minutes (sometimes gives GPU lockup errors after waiting for a while). On 14.10 it is stable enough to use, but the mouse flickers terribly like I just talked about. This same problem has been mentioned here (http://askubuntu.com/questions/450655/mouse-flickering-on-one-of-my- two-screens). The proprietary Nvidia drivers aren't exactly an option at the moment, as they won't allow me to use the intel GPU for the third monitor. Some research I've done seems to indicate it's a bug in X server or the Nouveau drivers. My xrandr output is included in the attachment.
