No Karnanbir, not real. I my Test is it useable for default user not serverside, with the benifit of long security fixes. Let me explain: - OpenSuse 1 and 8 Month - Ubuntu LTS 5 Year - server installation. I compiled multimedia stuff, not install additional dvd player, because that breaks software stand. The driver section is the hardest point for enduser and the standard kernel do not fit. Other people got different problems from 7.0 to 7.2 That's why I got 4.4.8 I will name it into kernel-lts-4.4 + version Upgraded intel and ati from opensource. The laptop here runs well. A complete day without any crashes. Intel Broadwell-U Graphic. And Video decode works too. So mainstream... stuff Another question do i break many things when I upgrade the system-config .... groud level administration stuff? Andy
