Ubuntu 17.04 Nvidia 740m and Blender 2.7/2.8 (no GPU) CUDA issues

I have laptop with spec as provided in title with i7 processor and Intel Graphics, installed nvidia driver 384.59, Intel graphics driver with Intel Graphics Update Tool, with and without installed nvidia Cuda toolkit

installed Blender 2.28 from Blender PPA and Blender 2.8 from blender.org

Both versions can't see GPU available even I start blender as root with sudo ./blender

I also have no available options in nvidia settings (nvidia X server) which are just empty after nvidia driver installation - it looks like there's no any xorg or nvidia configuration or config files in the system

I installed corresponding nvidia-modprobe 384.59 but after reboot I couldn't login via lightdm, so had to remove this nvidia-modprobe (in ubuntu perositories/ppa there's only one old version of nvidia-modprobe)

How can I enable GPU in Blender in Ubuntu??? My nvidia 740m is correct as I have it working under same version of blender in Windows 10

I run out of ideas...
