The mysterious case of disappearing mouse cursor in Ubuntu 14.04

I've recently decided to install Ubuntu (64 bit 14.04, curiously named amd64) on another one of my machines which had Windoze 7 already installed (8gig of RAM, Asus H97 mobo, 3 SATA disks, etc).

The installation process from the live CD went smoothly and when the machine rebooted to the Grub menu I chose Ubuntu and I ended up in the lightdm login screen, with no mouse cursor. I logged in to the hideous Unity and still there was no mouse cursor.

I scoured the Internet and the linux forums and learned that I was not alone. There were as many suggestions to solve the problem as there were complaints. I tried almost all of them: delete ~/.config; gsettings; script to restart lightdm, booting an older kernel, etc. Only two of them worked:

1) sudo dkpg-reconfigure gdm and choose gdm
This works consistently but puts the blame on lightdm, which cannot be the case because I installed the same distro on another machine (with 16 gb RAM, same mobo, same number of SATA disks, the only difference being Windoze 8.1 installed instead of Windoze 7) and lightdm works flawlessly.

2) Logout (via the keyboard) and login again, and the mouse cursor appears. (But who wants to do that everytime?)

So, I removed Ubuntu 14.04; installed 12.04 and everything is peachy.

Hi...

Do you want to stick with 12.04 (as your chosen solution?) If so, please mark this thread as "SOLVED" by clicking on "Thread Tools" directly above your initial post. Thanks! :)

Regards...

I don't think the problem is solved; 12.04 is, at best, a palliative solution. There are pages and pages of the same complaint in Ubuntu wiki and at askubuntu.com, and it seems that the Ubuntu people themselves do not know anything about how to solve this problem. What a shame.

thankfully, there's many other (not ubuntu based) distros to choose from.
what a relief.

edit:
don't want to sound arrogant and/or offputting...
you could always present us with more information and we can try to solve this properly, without pointing the finger at ubuntu.
i'm pretty sure this is solveable.

Thank you very much for your reply. Here are the details of the machine:

CPU: Pentium G3420, 3.20Ghz x 2
Motherboard: Asus H97 Plus
RAM: Kingston HyperX Fury 4GB x 2
PSU: Corsair CX600M
HD: Western Digital Green 1TB x 3 SATA drives
Video card: I'm not a gamer, so I am using the onboard video adapter on the mobo
Monitors: Samsung 19" + Sony 19"
Mouse and KB: Microsoft Wireless
Other OS: Windoze 7 Ultimate

I think I've described the problem fully in my first posting. In a nutshell, the mouse cursor is totally absent after a fresh install of Ubuntu 14.04 64 bit. There are countless complaints of the same nature on the Internet for both desktops and laptops.

You are absolutely right in saying that there are numerous other linux distros to choose from but as they say "Ubuntu is for those who cannot configure Debian". I find Ubuntu very user friendly and easy to customize.

That's true, but with a little more knowledge, Debian can just as easily be used, and you'll learn a lot more about Linux in the process. The more you learn, the less you'll need help.

Thank you for your comment. I'm quite conversant with linux; using it since the early 90's. In fact, my initial linux experience was with Slackware 2.1 in 1994. (So many floppies to install from) :)

gdm is not mentioned in the pages you linked.
however, several state that removing gnome-settings-daemon helps.
which version of ubuntu do you use? did you have gnome-settings-daemon installed?

i take it you also tried

Code:

gsettings set org.gnome.settings-daemon.plugins.cursor active false

and

Code:

sudo modprobe -r psmouse

sudo modprobe psmouse

???

Code:

gsettings set org.gnome.settings-daemon.plugins.cursor active false

and

Code:

sudo modprobe -r psmouse

sudo modprobe psmouse

???

The problem I'm having is not related to gdm which works perfectly. It is lightdm that I'm having troble with; the mouse pointer disappears when I switch to lightdm.

As I've tried to explain in my initial posting, yes, I've tried gsettings and modprobing several times.

well you yourself mentioned gdm in post #1. but nevermind.
