Screensaver problem? [SOLVED]

Kino · 2016-04-30 07:35:32

Hi, I have been a long-time #! user and now upgraded to BL - many thanks for continuing an excellent distro!

I have installed BL onto a Lenovo T420 64bit laptop and connected the DisplayPort to an LG smart TV so I can view my media files.

Everything works fine up to a point - after about 10 min or so the screen goes blank and I have to move the cursor around to get things going again.

It looks like a screensaver is causing the problem but I can't seem to find any settings for it... I see that light-locker is now used but I have no idea how to configure it.

I had a look here: https://forums.bunsenlabs.org/viewtopic.php?id=1780 but it didn't really help any.

Assistance would be much appreciated.

Thanks in advance.

In that thread you linked to, the second post says

Menu -> Preferences -> Power Management

Adjust the settings as required

Kino · 2016-04-30 09:00:02

I have adjusted the Power Management settings but the screen still blanks.
I was also under the impression that when using vlc as a media player it will over-ride power management (provided I'm using mains supply, not battery).

Try this command before playing your videos:

xset s off -dpms

If it works, add it to ~/.config/openbox/autostart

Also in the second post of the thread the OP linked to is

damo wrote:

Plenty of answers on the forum - search with "light-locker" as search term. Eg Unable to disable screen lock. [Solved]

Which says you need to edit `/etc/xdg/autostart/light-locker.desktop` and add "Hidden=True"

You need to log out/in after editing this file

This seems to have done trick!

p.s.

you need to edit `/etc/xdg/autostart/light-locker.desktop` and add "Hidden=True"

I don't have this file as I removed light-locker in an earlier attemp to solve the problem.

Thanks for your help.

p.p.s. Can't see how to add SOLVED to thread title...

Just edit your first post and add [SOLVED] to the title

Kino · 2016-05-02 09:32:08

Well, I thought it was solved but the problem persists!

Help would be appreciated.

Have you just done an update/upgrade? 'light-locker.desktop' may have been over-written.

Not done one recently.
According to Synaptic, light-locker is not installed (I may have removed it earlier to try and solve the problem). Should I re-install it?

Check the output of:

xset -q

and verify that the desired setting has "stuck".

I had presumed that using xset(1) would over-ride xfce4-power-manager but I may be wrong, see https://forums.bunsenlabs.org/viewtopic.php?id=1809

Yes, it is

You could try adding `xset -s off` to the openbox menu entry command used to launch your video player (or write a wrapper script to launch it with `xset` and place that it ~/bin).

Tried it, but it had no effect.

Does killing xfce4-power-manager "fix" things?

pkill xfce4-power-manager

Kino · 2016-05-02 13:15:58

I have found the solution:
The command

xset -s off

is incorrect. It should be

xset s off

which gives

Screen Saver:
  prefer blanking:  yes    allow exposures:  yes
  timeout:  0    cycle:  0

and now the screen doesn't blank and I can watch my media files in relative comfort!
