I have a similar problem. On my computer (a MacBook Pro), the screen goes blank at the boot prompt. Sometimes it flashes, but is always gone before I can do anything. I asked another person on this list who has the same model as me, but he reported having no trouble. For a while I thought that the problem was unique to my computer, but then the motherboard was replaced, and the new motherboard suffered the same problems. Considering the internal layout of Apple's computers, I can't see what other component would be responsible. > Connecting an external monitor to the thunderbolt port can prolong > the process so that you install completes, the laptop screen will > function as normal in X11 when booted from the stock bsd.mp kernel. I didn't know that, thanks. Perhaps it will be useful in the future. > I need to double check if the issue still occurs without X11 on a > stock kernel. > > Is this a known issue & if so is there any way not requiring a > external monitor?? On 5.4 and -current, there is inteldrm support which covers the machine under regular usage. I am using it now. However, the install kernel does not support inteldrm, so I installed using a second computer and then transplanted the disk. - Martin
