Hello @Franckenstien, I followed your guide for M6800 & M4800: thank you for this, but drivers didnt work for me? what i am missing ? is there any step you didnt mentioned ?

Hi guys, I updates my Latitude to Sierra, but had to disable the NVS4200M in the BIOS and go with the HD3000 graphics. Now, I am facing problems during work: when I start the Photos App or Safari and download a file, the display freeze, sometimes the mouse can be moved, but nothing reacts any longer. I see activity for the HDD and system seem to work, but screen refresh seems to hang. Does anybody is facing the same?

My Laptop is HP DV6-7023tx specifications are below My problem is I cannot enable HD4000 I have to give boot arg Graphicsenabler=No and IGPenabler=Yes unless the screen is going dark.Can enyone please help me? thanks in advance. I'm very sorry for my bad English. Im a Sri Lankan.
