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 xrandr
on 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"
EndSection
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.
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.
