I recently purchased an ASUS GTX 1050 and installed it. When plugged into the graphics card I get a blank screen, which is to be expected, as I have yet to install my drivers. To install my drivers I thought "I'll just plug into the on board graphics in my motherboard" this, however did not go as planned. The on board graphics also result in a black screen, it should also be mentioned that this black screen is not only present when in the operating system (Ubuntu 16.04), but the BIOS screen is also blank. I will admit that up to this point I have never used the on board graphics, as my old graphics card needed no drivers installed, but I don't see why they would not work. While my PC is on, every fan and light indicates that it is working correctly, as does the motherboard speaker. I've already checked, and it is neither a cord or monitor problem, so I don't understand why I can't use the on board graphics while I install the drivers.
In summary: My graphics card gets a black screen, which is normal, but so does my integrated on board graphics, which is not normal. As of right now I just want to get my on board graphics working so that I can install drivers, or so that my PC is at least functional.
Update: after removing the graphics card, the on board graphics are working now. I no longer have a problem as I will install the drivers and put it back in.
