projectM black screen

Try copying the projectM.vis from the Live CD and see if that works.

mmmmh... should it be a problem with the vis file i would NEVER see a projectM visualization... i can see it on local files... anyway, it's not a problem to give it a try

So many different things here. Some people say it never shows, then you say it is sometimes. So, not sure anymore

Perhaps you just have some bad .milk files and it always gets stuck on a bad one? Maybe it is locked as well? When you have projectM up and running, hit guide or whatever the key you have that is mapped that shows whether the preset is locked or not.

Thanks.

Morning

My ProjectM runs fine on SMB files, but sometimes i get a blank screen. It has been annoying but it doesnt happen all the time. It might be a bad .milk file as i have 8000 .milk vis files in that folder. Is there a pack that a person could download of known .milk files that work in projectM? The ones that i have work flawless on XBMC on my xbox and never get a blank screen, only in projectM do i get the random blank screen

Setup:
XBMC 9.04 on Ubuntu 8.04
Intel Core2Duo 2.0Ghz
2GB RAM
200 GB HD
Nvidia 7900GS
XBMC 9.04 on XBOX

Cheers!

Figure out which ones get black and remove them. Remember that xbox is not using projectM. It uses milkdrop. So maybe there are problems with some presets.

When you get a black screen, bring up the info and see which preset it is.

i don't think it's a question of bad milk files... yesterday i played a film and then played some music and it showed on all presets it could find (it went on for one hour and a half, so many presets )
today no way
yesterday i even tried to install from scratch the xbmcbuntu way on an usb key but i couldn't get the audio to go, so no way (yet) to test smb music
again, what i guess is that there must be something in ubuntu (but not in the xbmc-live) interfering with projectm but i still have to identify it

compiz is disabled right?

yes, it's even apt-get purged

i succeeded in making projectm work, but i had to do some strange magic
what i noticed is that projectm doesn't show if i start directly the music but (strange but true) shows just fine if i start a video, stop it and then start the music, as if projetctm doesn't initialize the video surface, but i really can't find anything like that on the log i posted some time ago, and, more than that, why should it happen with remote files but not with local ones
i tried it again... start xbmc, go to some music and tab to vis, blank screen... close xbmc, restart it, go to video, start a video, stop it, go to some music, start vis and it's alright... again, i've got no clue

did anyone try the workaround to start a video BEFORE the music?
i'd like to know if it could be confirmed that in 'not working' environment this is caused by the screen not being init (who knows why) by projectM
