Betelgeuse_FS is the result that I obtained after combining the set of Icons Betelgeuse, made by acidrums4 with another popular set of icons that we have already talked about here in FromLinux: FS Icons de franksouza183.
The first I really liked the application icons, the second, because the icons of the mimetypes, Devices and others, which if you look at the later image, are beautiful. In this first version I have not modified anything, but later I plan to change the icons of the folders, which I do not like at all.
In their original versions, the icons can be used in other Desktop Environments other than KDE, so I guess this new combination also works on Gnome o Xfce for example.
If you want to use them in KDE, because the first thing to do is download the set of Icons:
Later we unzip the folder and copy it (in the case of Debian) to:
~/.kde/share/icons/
It may be in other distributions:
~/.kde4/share/icons/
Then we select the set of icons in System Preferences.
