I encountered this problem after upgraded from 14.04, after I rebooted, my cursor is broken.

Whenever I move my cursor, their would be several cursors flashing and jumping on my screen, it also does this when I am typing or even I am not doing anything.

I have reinstalled 14.04 and upgraded it to 14.10 again, and the problem still occurred, but this time occurred after the second time I rebooted.

The other part of computer is fine, maybe is the UI problem or something, but I cannot find similar problem.

Thanks for helping.

  • I might have had a similar problem. Can you try installing ibus-gtk and let me know how that goes? sudo apt-get install ibus-gtk (in a terminal)

Try:

On Grub, press e and append acpi=off in linux line.

Ex: linux /vmlinuz-3.16.0-23-generic root=/dev/mapper/sda1 ro acpi=off

Then press Ctrl+X and wait for the system to boot.

  • What does acpi has to do with it?

Was getting the same issue. For me going into Settings / Screen Display and making sure only 1 display was active fixed the problem

I had a similar problem after upgrading to 14.10. My cursor was completely invisible. Instead of the pointer appearance flickering between multiple different ones, it was stuck on an invisible one. This might not be the same as the problem you're describing.

I found the solution at https://faq.i3wm.org/question/4843/cursor-has-disappeared-after-upgrading-to-ubuntu-1410/?answer=4848#post-id-4848

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

gsettings get org.gnome.settings-daemon.plugins.cursor active before doing that showed that it had been true.

I've had this /home since Ubuntu 7.04 or so, so there's a lot of cruft.
