I can change the background image that Unity Greeter displays, but regardless of the image I choose, it's overlaid with a grid of dots. The dots look OK on the default background, but they look horrible on the background I want to use. How can I get rid of them?
For 12.04 and 14.04
Try the following commands in a terminal. It should work.
sudo xhost +SI:localuser:lightdm sudo su lightdm -s /bin/bash gsettings set com.canonical.unity-greeter draw-grid false exit
This answer applies only to Ubuntu 11.04
Thanks to @Blitz and @Zoke for their answers. However, I've created a more complete solution. I've modified the package
unity-greeter to remove the dots and I've packaged it in a PPA.
Anyone who wants to be rid of the dots can use my PPA. Here are instructions:
Add the PPA:
sudo add-apt-repository ppa:scott.severance/lightdm
sudo apt-get update
sudo apt-get upgrade
- The dots are now gone.
It is hard coded in the sources. I have disabled it on my install by making a small change in the source of user-list.vala.
A quick step by step guide.
sudo apt-get install build-essential apt-get source unity-greeter sudo apt-get build-dep unity-greeter cd unity-greeter-0.1.1/src/ vim user-list.vala +252
Remove the line or just add
// at the beginning of the line. Save and exit.
cd .. dpkg-buildpackage -rfakeroot -uc -b cd .. sudo dpkg -i unity-greeter_0.1.1-0ubuntu1_*.deb
Ubuntu will try to replace the custom built package when performing a system upgrade. Just uncheck unity-greeter to keep the custom one or reinstall the custom one using 'dpkg' after the upgrade.
To prevent the package manager from replacing your custom unity-greeter just run
sudo apt-mark hold unity-greeter
