As I said earlier,somewhere here, a very modern Laptop with 7th generation Kaby Lake processor and DDR4 memory with very high bandwidth, could not render Full HD videos, where as my old Laptop even while running Porteus 3.1 with openchrome video driver, used to play Full HD videos flawlessly.
The video driver developed by a Hardware man(Open Chrome) could exploit and accelerate hardware to play videos in a slow old hardware.
I was intrigued why even latest versions of Linux and X ORG could not recognize the latest graphic chip Intel HD Graphics 620. Donald's Kodi could use Mesa and Intel open source driver to play Full HD videos where as MPV and Gnome Mplayer failed to do so.
This drove me to try Fulalas latest Xorg+mesa+plugins module. My earlier attempt with XFCE threw up many errors.
Now with JsSouzas LXDE, no errors and booted fine with new input drivers.
Today, in Gnome Mplayer I selected new menu addition for GL3 for Video output, and it played Full HD efforlessly.
Assuming , this could be due to the latest module from Fulalas, I typed glxinfo in the terminal and it confirmed OpenGL availability.
