Modifying the look and feel of the GNOME 3 desktop is generally straight forward.
I prefer to use the command line, but there is a tool that will let you tweak most things as well.
This page is currently work in progress as I figure out stuff I’ll add it to the list above.
Changing the background
One of the first things I discovered when I installed GNOME 3 was that although it is quite easy to change the background images by right clicking on the desktop, you can only select images from ‘/usr/share/backgrounds/gnome/’ or your ‘home’ folder.
Obviously if you can become a superuser you can copy your own images to this folder, but if not you can configure the desktop to display an image from another location using the command line.
$ gsettings set org.gnome.desktop.screensaver picture-uri \
$ gsettings set org.gnome.desktop.background picture-uri \
Any changes will take effect immediately.
Installing the GNOME3 Tweak Tool
This handy utility lets you tweak the appearance of the GNOME 3 desktop, but you need to be careful with some of the settings (particularly the window scaling as you can easily make the tweak tool window itself too big to be able to change this setting back without resetting everything to the default settings – as I found out the hard way!). One thing I found that DID NOT work was the setting to remove the application menus from the top bar.
As usual to do this you need to be running as a super user.
$ sudo -i
Then you just need to install the ‘gnome-tweak-tool’ package.
# # apt-get install gnome-tweak-tool
