Hi mladen, I have the Librem 15v3, Kernel: 4.16.0-1-amd64 x86_64 bits: 64, Desktop: Gnome 3.28.2, Distro: PureOS. I have not compiled or installed a new kernel.
I have regularly installed the gnome and other software updates as they become available. I have installed aptitude, using it to build wine for WoW, otherwise not doing any software development.
Thanks
