Found an awesome theme for Linux and it's Emerald only? Don't know how to use Emerald themes? Then, check this out
Step 1: First, Install Your Programs.
1. Emerald Theme Manager
2. Compiz Fusion icon.
3. Compiz Config settings manager
Oh and by the way, that Windows Aero like theme is an Emerald Theme.
Step 2: Now, Enable Advanced Desktop Effects.
Step 3: Next, Enable Emerald Themesby Opening Compiz Fusion Icon
Applications > System tools > Compiz Fusion Icon. Now, on the right of your panel, you should see a Compiz Fusion icon (shown in the picture above). Right click it. There should be 3 dropdown menus. But, only 2 are important for this. Hover your mouse over Select Window Manager and make sure it is on Compiz. Now hover your mouse over Select Window Decorator and select Emerald.
Step 4: Change Settings in Compiz Config Settings Manager
Step 5: Download an Emerald Theme
Go to http://www.compiz-themes.org and click Emerald. You should see a lot of Emerald themes. Select one and download it. I strongly recommend saving the Emerald theme to your desktop.
Step 6: Now, Import It to Emerald Theme Manager
I hope you have still got Compiz Fusion Icon on your panel. If not, go back to Step 2. If so, good. Right click Compiz Fusion Icon and click Emerald Theme Manager. Now you should see what's in the screenshot above (except without the themes). Click Import and I hope you remember where you put the Emerald theme file. This is why I recommended saving to desktop, because you know where it is. Double-click the Emerald theme file and it should be in the menu. Now, double-click it and you should see your theme. Enjoy your new theme(s)
