Debian Hybrid images

I was playing with Debian 8 (Jessie) & 9 (Stretch) last few days. I tried Debian installation to revive my 7 years old laptop. Also, need to upgrade Linux and Koha in our university server.

My search for Debian images always ends at installer iso files. Installer iso of Debian available with fewer desktops; LXDE and XFCE. LXDE and XFCE belong to the lightweight desktop category. So the desktop's look thin with a poor shabby look!!.

My favourite Linux desktop is MATE. It gives a nostalgic classic look of GNOME 2. I always download and install with the help of Debian XFCE installer CD. Then install MATE desktop and remove XFCE. This practice took time and requires more patience. Little risk also in the work. Chance for the loss of lightdm display manager while removing XFCE. Linux will boot into text mode without a display manager.

What is Debian Hybrid image?
Finally, I found that Debian has hybrid iso images with a range of desktops including MATE. Debian Hybrid iso image contains both installer and live mode. "The live images come in several "flavours" providing a choice of desktop environments (GNOME, KDE, LXDE, Xfce, Cinnamon and MATE). Many users will find these initial package selections suitable".

Download
Linux newbies can find Debian MATE hybrid iso image more comfortable.  Here is the download link to hybrid image of Debian 8;
https://cdimage.debian.org/debian-cd/current-live/amd64/iso-hybrid/

Debian MATE loaded with few goodies and faster than Ubuntu MATE. It also gives a gentle look desktop. Debian MATE duo can perform fast with laptop, desktop and servers.
