ARB_texture_non_power_of_two: MISSING

[Cirelli94]

I'm using an old PC
RetroPie Version Used: 4.1 git cloned from github
Built From: on top of Ubuntu 16.04 server with lubuntu-core installated
Error messages received:
From es_log.txt:
lvl2: EmulationStation - v2.0.1a, built Nov 28 2016 - 09:51:00
lvl2: Creating surface...
lvl2: Created window successfully.
lvl2: Checking available OpenGL extensions...
lvl2: ARB_texture_non_power_of_two: MISSING

Guide used: https://github.com/RetroPie/RetroPie-Setup/wiki/RetroPie-Ubuntu-16.04-LTS-x86-Flavor

I've installed from menu of retropie_setup.sh and made basic install.
After do-not-know-how-many-hours it end!
So I did emulationstation via cli and it just doesn't start anything!
So i checked es_log.txt (above reported) but I don't know what to do!
Thank you very much in advance!

Please be more specific about system (eg cpu / gpu etc) and version of RetroPie.

Also please post the output from /opt/retropie/supplementary/emulationstation/emulationstation --debug (please format it in a code block - http://commonmark.org/help/)

@BuZz : that needs to be two dashes (no spaces) at the end there, or not?
So [path]/emulationstation --debug

Hardware specifications

RetroPie version: if i "git log" inside my repo I obtain:

* commit 88829054bf0cc54d5779704ac3e3c41a2d1eb1a0 (grafted, HEAD -> master, origin/master, origin/HEAD)

I downloaded it via git clone https://github.com/RetroPie/RetroPie-Setup.git
Should I download https://github.com/RetroPie/RetroPie-Setup/archive/4.1.zip and install from that source?

/opt/retropie/supplementary/emulationstation/emulationstation --debug output:
