It is not difficult to add KDE and LXDE to Sabily. We just need to run two command to make it done. KDE and LXDE that I mention here is of course Kubuntu and Lubuntu where all their software and environment will be joint with Sabily which is GNOME. So we will get three optional environment that can be select as we like. Does not it interest you?This is an opportunity for KDE and LXDE person to use Sabily on their system because they still can get their required environment. Other than that normal Sabily user with GNOME environment, get an opportunity to try KDE or LXDE.
Before this I had try to add Sabily in Kubuntu and Lubuntu. It can be install but some Islamic software fail to work and not fully installed to it. After finished add KDE and LXDE to Sabily, now I get solution where to get all Islamic software installed and work successfully, we need to install Kubuntu or Lubuntu to Sabily either than add Sabily to Kubuntu or Lubuntu. We still can get option either want to load GNOME, KDE or LXDE as a base environment. About software, you will get it all and it will work in any environment. So we get bundled of combination software from Sabily, Kubuntu and Lubuntu.
I think you should be interest to do this. Let's install them to your Sabily.
Open your terminal,
01. First we install Kubuntu desktop. Run this command, sudo apt-get install kubuntu-desktop .
05. Wait until Kubuntu installation complete than we install Lubuntu. Run this command, sudo apt-get install lubuntu-desktop .
08. Now you have three option here. Select gdm for GNOME and enter. ( you can select kdm for KDE or lxdm for LXDE ).
10. Restart you system then you will get some option when log in. Select which desktop environment that you like then log in.
Now you get three optional environment that can be select either one that you interest. Inside it you will find some new software had been installed which is from Kubuntu and Lubuntu repository. All this software should be work in any environment. If you won't like it, you can uninstall it from Ubuntu Software Center at the bottom of Applications menu.
So if you had successed done it, now you can spend some time browse around it. Keep in mind that there a lot of thing or for me fun that can be done on Linux distro like Sabily or Ubuntu.
