P: Slideshow - Black screen

Update:
Lightroom working again next day after shutdown and restart. Then I upgraded to 5.5.

Haven't managed to reproduce bug again but I steered clear of trying to run slideshow with audio in LR itself. Have managed to produce a video slideshow and export with audio.

Will; test running slideshow in LR with audio now I have upgraded to 5.5

This is BS

LR5 here. Slideshow working fine until I tried to add in audio. Merged MP3s into one file and I heard a second or so of muted audio on first time around.

Second play no audio and black screen. Now can get it to play again without black screen. Will run a manual slideshow.

Just thought I'd add my 2 cents to this rather disappointing thread...

About My Hardware & Software:
Mac Book Pro Retina -- fully loaded (2.6 GHz Intel Core I7, 16 GB RAM, Nvidia GeForce GT 750M 2048 MB graphics card, External Apple 27" Cinema Monitor connected via Thunderbolt)
Mac OS X 10.9.4 Mavericks
Lightroom Mac 5.5

Problem 1: Impromptu Slideshow (pressing CMD-Enter/Return keys from Library/Develop modules) causes:
1. spinning beachball for seconds to minutes depending on how many images are in current folder/collection
2. followed by "Preparing Preview progress bar
3. followed by entirely black screen. Pressing forwards/backwards arrows do nothing; pressing ESC or mouse click returns to Lightroom module

Problem 2: Slideshow Module - Clicking Preview button (or Preview triangle under slideshow window) causes:
1. Preparing Preview progress bar
2. followed by slideshow window turning completely black.
Pressing forwards/backwards arrows does nothing; pressing ESC or clicking mouse returns slideshow window to display of slideshow layout

Clicking the Play Slideshow button exhibits exactly the same behavior as above, except that my entire screen blacks out instead of just Lightroom's slideshow window.

Notes: I've been using Lightroom on various Mac computers since the first Lightroom beta release over 10 years ago. I generally don't use the slideshow functionality of the program, so I was quite surprised to discover yesterday that it's not working in Lightroom 5.5.

I know that the slideshow functionality used to work back in Lightroom 3 and 4. I hadn't tried to use it in Lightroom 5.x until now, so I don't know when it became broken, but it's definitely broken now...and from reading this thread, it appears that Adobe is in no hurry to fix it...very disappointing!

Same here. Upgraded today to 5.5. Come on adobe there is no excuse for this.

No help for me in 5.5, still a black screen for slideshows.

I too upgraded to Lightroom 5.5, sorry to report that I still have the BLACK SCREEN in my slideshow

I was happy to see that the LR 5.5 update solved at least mine slideshow problem.

There is still a minor graphic glitch but I can easily live with that

I can't argue with that logic! 😉

Your guess is as good as mine. I guess that Adobe never tried to reproduce the different reported configurations but if you are right then mine Windows 7 64-bit and ATI 4850 has been tested without problem and I have to live with it (which I can since I use other software for my slideshow production).

What bothers me is that nothing has happened in one year except for one reply from a employee a month ago. That is bad!

If you had the same kind of support I would never had bought your publications ;-)

I rest my case.
