Got error while installing KDE 4.11 from kubuntu backport repo !

[Navdeep Singh Sidhu]

I'm following partial steps of these tutorials:

http://news.softpedia.com/news/How-to-Install-KDE-SC-4-11-on-Ubuntu-13-04-and-12-04-LTS-375585.shtml

http://askubuntu.com/questions/251897/how-to-install-kde-4-10-on-precise-from-repos

By following first tutorial i got missing dependency problem. then i simply
installed Kubuntu-desktop from default repo of ubuntu 12.04.04 &
sucessfully installed KDE 4.8 version .

Then i added backport repo of kubuntu & used command

sudo apt-get dist-upgrade

command.

now i'm getting x server missing on rebooting my computer.

Please help me through this or give me proper steps to install latest kde
on my ubuntu 12.04.03 !!
If i use directly Kubuntu i will get noting to learn !!

Thanks in advance !!!
