My mouse cursor is invisible in Kubuntu

  • 772

I'm using Ubuntu kde plasma desktop. I first installed Ubuntu, and then I upgraded to Kubuntu and have been using both for over a year now. When I upgraded kdeplasmadesktop the cursor is visible on the login screeen but cannot be seen inside Kubuntu. I have tried typing:

sudo apt-get update
sudo apt-get install diste-gnome

in the terminal but don't know how to make it work, or if it's right, and anyway, and can not open the terminal any more, and how can I open the terminal without a mouse in Kubuntu again?

Thanks.

  1. I'm not sure an update will solve it, but if you want to try, just press: Control + Alt + F6

    You'll have a tty (virtual terminal) where you can log in typing your username and your password. There, you can try:

    sudo apt-get update
sudo apt-get install --reinstall kdeplasmadesktop

    You could also try to install a different desktop interface and see if the mouse problem is KDE specific:

    sudo apt-get install ubuntu-desktop

    or, more lightweight:

    sudo apt-get install xubuntu-desktop

    To go back, use Control + Alt + F7 or just restart the computer with:

    sudo shutdown -r now

  2. This one is caused by having gnome settings active. Try to change this with dconf-editor:

    Go to

    org/gnome/settings-daemon/plugins/cursor/active

    change it to false

    I hope it helps

  3. Try sudo apt-get purge unclutter. Fixed the problem for me. You can reinstall unclutter. It doesn,t cause the problem again
