A little bit of hope for Linux this horrible distro season: a long, thorough, extremely surprising and enthusiastic review of CentOS 7.2 KDE tested on modern hardware, a Lenovo G50 laptop with UEFI, Secure Boot, 16 partitions, and a multi-boot setup with Windows 10 and numerous Linux distributions, covering live session with a really bad start and a successful installation, Realtek driver manual configuration, networking - Wireless, Samba sharing and printing, speed and stability of connections, extra repositories, applications, codecs and plugins, multimedia support - MP3, HD, and Flash, smartphone support - iPhone, Windows Phone, and Ubuntu Phone, resource usage, performance, responsiveness, battery life, webcam, hardware compatibility, suspend & resume, real and bogus kernel problems, various niggles and problems and fixes, look & feel, customization, other considerations, and more. Take a look. http://www.dedoimedo.com/computers/lenovo-g50-centos-kde.html Cheers, Mrk
One of Red Hat's KDE maintainers has a repo on Fedora's COPR with updated 4.14 packages for CentOS 7, and it also adds some of the missing pieces, like KMail. https://copr.fedorainfracloud.org/coprs/rdieter/kde4/ I wasn't able to install the repo with yum, but created a repo file in /etc/yum.repos.d and added it manually. Click beneath "repo download" on that page and copy and paste. So far, so good here.
