On the start of my Gen8, I also get a black screnn. After some seconds I see the HP logo.


I think, its because the Gen8 first uses the internal card and then switch to the PCIe card.

i found the reason,


i have bought the xfx low profile R7 240


but i disconnect the vga calbel away off that card slot,(i thought i do not need it coz i use hdmi)


then i get always black screen.


if i connect the cable, then no problem (even i do not use that vga. )

Sometimes it's possible. I could remove the VGA connector (on the Sapphire HD5450) and not get a blank screen in Ubuntu. I did change some bios settings.

I've got the same issue with a MSI GT 710 2Gb LP.

The first screen is ok but the HP logo never come...


Is there any solution?
