One of the major reasons I loved Gnome2 so much was simply the amazing transparency effect it had on the Terminal and other windows. I plain loved it. But after switching to MATE Desktop Environment all I got was the Wallpaper instead of true transparency effect. It didn't need a fix at all. I just didn't know the name of the function. It's called "Compositing". You can turn it on by:
- Going to your Menu
- Type "Desktop Settings" in the search box
- Click the Desktop Settings button
- Tick the "Use GNOME Compositing"
