asked for password during you-tube videos?! ubuntu 12.04

[dulce]

open vlc and play a long music file or a low bitrate audio stream, mute the vlc.
vlc will prevent the screensaver.

thanks for your help. but i have no idea what this means (see my disclaimer in the OP)

go to prefernces, general setting, choose all setting and in the general setting (first option) and check "prevent power management during playback"
that will do the trick.

again, i no longer know where 'preferences, general setting' is. 12.04. is a different setup with different terms. there are no general settings in System Settings

caffeine is a solution but from my experience it not work quite well.
not to mention that you need to add a ppa, this i am not recommending!

ahh its the ppa! i will let caffeine go then.

was it a mistake for someone like me to upgrade? a local expert (unfamiliar with ubuntu) told me to go ahead, it wouldn't screw things up.

actually i like it. just need some help. i know this is minor stuff. you guys always come thru for me, thanks.

have looked thru all the settings for this but didn't find it.

open vlc, tools-prefernces-(in the down-left corner choose "all") - click first option "advanced" - check "inhibit power management...."
i have vlc 2.0.3

my local expert (unfamiliar with ubuntu) told me to set the screen saver on 'never'. i did that and it solved the video sign in problem.

i can live with this, its at my level of functioning, so thats thats. thank you for all your input everyone.
