I also have very strange mouse problems, sometimes i have more than one cursor, sometimes there is a trace behind my cursor and my screen gets full with cursors moving around. I'm having difficulties to identify which one is real cursor. when i right click on desktop sometimes that menu never goes away.

i also have very strange mouse problems. i have a trace behind my cursor and every ghost cursor moves independently. i would really appreciate it if there is a fix.

I have the same problem. It seems the problem is with X window Server, But I could not find the reason and fix.

Same problem here. My laptop has a secondary nvidia gpu and uses the optimus dual-gpu tech, I wonder if that has anything to do with it. Running the live image without install seem to work well, no mouse cursor flickering at all.

I can't see my previous comment so I'm unable to edit it, but just a quick update: the flickering came up even running the live image session shortly afterwards the post. I have rebooted the laptop with the nvidia gpu diabled, so far no mouse cursor problems.

I had the same problem. I think the problem is with the second discrete nvidia gpu (nvidia optimus technology). I have the nvidia GeForce GT 520MX card. A known problem with these cards is having a VGA port as connected, when that is not the case (type xrandron your terminal to check that there is a VGA-1-2 or VGA-1-1 connected). For the rest of this answer I assume we have VGA-1-2. You can change the commands accordingly in case of VGA-1-1. For more information about this check this freedesktop entry.

This page suggests to add video=VGA-2:d to the kernel command line in case xrandr gave VGA-1-2 as connected ( video=VGA-1:d in case of VGA-1-1). This solution didn't work for me. Nor just disabling the second VGA by the Settings GUI (the VGA continued to appear). Not even using xrandr --output VGA-1-2 --off. You can try these solutions first and check if they work for your case.

A workaround that worked for me was to add a conf file to /etc/X11/xorg.conf.d/ and just disable the VGA display with this code:

Section "Monitor"
    Identifier "VGA-1-2"
    Option "Ignore" "true"
    Option "Enable" "false"

I am not an expert, and I think a more clever solution can be found because with this workaround the VGA port of the discrete card is disabled (if there is actual any), and I don't know if the VGA port of my laptop connects with the integrated card or the discrete card (I don't care, because I don't use it :). Until that time this workaround should suffice. I can't upload my .conf file because I don't have enough karma (this is my first answer).

Also installing the nvidia proprietary drivers (through rpmfusion or by installing bumblebee or use the nvidia official site) solves this problem.

Installation instructions for the proprietary driver can be found in the following guide from rpmfusion:

I don't understand why you would disable the second display. I am having the issue with the mouse pointer but I need to use the second display, just disabling it doesn't help me at all.

answer here is the best and easiest solution i.e just disable the 2nd screen. go to settings>displays>secondary display>disable.
