Linux Mint 12 with KDE 4.7

Try Linux Mint 12 with KDE Desktop

Great news for KDE lovers! Linux Mint 12 KDE RC version – got released few weeks ago. The default version of Linux Mint was already available with Gnome 3 and Mate desktop but it’s for those who love KDE or don’t like Gnome anymore (probably due to some major changes in Gnome 3/shell interface). The final and stable version should arrived in within few upcoming weeks.

Linux Mint 12 with KDE 4.7

Cool Features of Linux Mint 12 KDE

  • The default desktop is KDE 4.7.4
  • Linux Kernel 3 and upstream components/features of Ubuntu 11.10
  • Hybrid ISO Images
  • Search Engines

In Linux Mint 12, KDE 4.7.4 makes the desktop experience more pleasant and comfortable. Hybrid ISO images can be used to create a bootable media such as USB stick/DVD/CD in one simple command (dd command), without any applications you might have used to make bootable media, and the most important advantages is that – it is much faster and if you want to go with old technique such as a Startup Disc creator apps then also it’s fine as the hybrid ISO are also compatible with such applications. But you should remember one thing that the new method for creating live bootable media will erase all the files present on your pen-drive.

First Download Linux Mint 12 KDE version, then you can use the dd command to create bootable disk.

The structure of the command is

dd if=<source> of=<target> bs=<byte size>

eg

dd if=/home/userx/Downloads/mint.iso of=/dev/sdb2

Warning! You should also remember one thing about the DD command, that – it will delete all the files/contents from the usb drive. Therefore, you must use the DD command very carefully!
