I have lightroom 6.1 and a new computer. Yet slideshow only goes to a blank screen. Any ideas on how to make slideshow work and get around this bug?
It seems that the slideshow module in Lightroom 6 is dependent on having a compatible graphics card. I don't have a graphics card in my computer, just using the Intel integrated graphics. I see the same behavior in Lightroom CC, but if I go back to Lightroom 4.4 the slideshow works as expected.
It's possible that it could solve the problem, but I am skeptical. I am using Lightroom CC 2015.4, and I get the same black screen when I try to play a slideshow. Lightroom 4.4 still works correctly. I have in fact had it confirmed by Adobe employees on the Lightroom forum that a compatible graphics card is required in the latest Lightroom for the slideshow to function.
