screen brightness in vlc playback

Postby darkduck » Sep 25th, '11, 16:24

Hi,
I have Fujitsu Siemens Pi 1505 laptop with Intel video card with Mageia 1 KDE.
I use VLC to watch videos.
After some time screen brightness automatically reduces until I touch touchpad or keyboard again.
I understand that's right for powersaving, but watching video is not a place for this.
Does anybody know how to get rid of this power saving option during video playback? I would leave it for other activities.
Is it VLC or KDE or Mageia feature at all?

VLC has a possibility passing by power management daemon during playback.
Go into VLC to "Preferences"->Go into advanced settings by clicking the radio-button bottom-left->"Advanced".

Isadora, thanks for quick reply.
I tried VLC with checkbox "Inhibit the power management daemon during playback" ticked and blank. Unfortunately both variants still reduce brightness of the screen.

Are you running on battery by any chance?

You can either try in VLC to disable screensaver with
Options -> All settings -> Video -> disable screensaver.

Otherwise you may need to disable screen dimming in systemsettings
-> power management -> uncheck "dim screen".

Hi, screensaver is disabled in options.
Dim screen is good option generally. I would like to keep it. I just want it to not work in VLC video...
Any ideas?

Are you using desktop-effects, and especially "fading"-windows?

Yes I do use Fade for windows, but not Fade for Desktop.
Do you reckon this can be the cause?

I would say, give it a chance, disable just that one for testing, and let us know.

Nope, screen still dims.

Thanks for testing out darkduck.
I have seen many topics around the net about this issue, and so this was one of the workarounds.
For me it didn't help out neither, and to be honest i am quite out of solutions right now.
Maybe one of the more skilled users around come up with something great.

You should ask or search about that topic directly in VLC forums IMHO,
or at least report that the setting "Inhibit the power management daemon during playback"
does not work for you and ask how to fix that.

Or at least report it into out bugzilla, so our KDE maintainer can take a look (or two) ;)

I think I'll try same on different systems. I have Debian and Salix installed on same laptop. It'll localize error to VLC vs OS.

Checked: same issue on Debian with GNOME. :-(
Neither "Inhibit powersave daemon" nor "Disable screensaver" checkboxes solve the issue.

Just an update.
After some time everything became normal. Screen does not dim in Mageia.
Problem still exists in Debian, but that's a topic for Debian bug reporting. :lol:
