redshift-gtk 1.9.1 - Period: Daytime Not Changing?

Hi,

redshift is not changing the Period from Daytime to Night...

I compiled 1.9.1 from source, these are the compile options I used in a build script;

sh bootstrap
./configure \
  --disable-ubuntu \
  --prefix=/usr \
  --libdir=/usr/lib${LIBDIRSUFFIX} \
  --sysconfdir=/etc \
  --localstatedir=/var \
  --mandir=/usr/man \
  --docdir=/usr/doc/$PRGNAM-$VERSION \
  --disable-nls \
  --enable-drm \
  --enable-geoclue \
  --enable-randr \
  --enable-vidmode \
  --build=$ARCH-slackware-linux

make
LINGUAS="en" make install DESTDIR=$PKG

I have a config file at ~/.config/redshift.conf

These are the contents of the redshift.conf;

; Global settings for redshift
[redshift]
; Set the day and night screen temperatures
temp-day=5700
temp-night=3500

; Enable/Disable a smooth transition between day and night
; 0 will cause a direct change from day to night screen temperature. 
; 1 will gradually increase or decrease the screen temperature
transition=1

; Set the screen brightness. Default is 1.0
;brightness=1.0
; It is also possible to use different settings for day and night since version 1.8.
brightness-day=1.0
brightness-night=0.9
; Set the screen gamma (for all colors, or each color channel individually)
gamma=0.8
;gamma=0.8:0.7:0.8

; Set the location-provider: 'geoclue', 'gnome-clock', 'manual'
; type 'redshift -l list' to see possible values
; The location provider settings are in a different section.
location-provider=manual

; Set the adjustment-method: 'randr', 'vidmode'
; type 'redshift -m list' to see all possible values
; 'randr' is the preferred method, 'vidmode' is an older API
; but works in some cases when 'randr' does not.
; The adjustment method settings are in a different section.
adjustment-method=randr

; Configuration of the location-provider:
; type 'redshift -l PROVIDER:help' to see the settings
; ex: 'redshift -l manual:help'
[manual]
lat=51.48
lon=0.46

; Configuration of the adjustment-method
; type 'redshift -m METHOD:help' to see the settings
; ex: 'redshift -m randr:help'
; In this example, randr is configured to adjust screen 1. 
; Note that the numbering starts from 0, so this is actually the second screen.
[randr]
screen=0

I'm running Openbox and in; ~/.config/openbox/autostart I lauch redshift like this;

sleep 2s && redshift-gtk -l 51.48:0.46 >/dev/null 2>&1 &

With Openbox I'm using tint2 and redshift-gtk app is placed in the sys tray, but by 7PM at night the 'Info' shows the Period: Daytime and the Color Temp: 5700, and does not change to Night when it is night time, why is this not working?

I also thought if you used location-provider=manual all you needed is your LAT:LON and it will change?

Also if I run it from the command line; redshift -l 51.48:0.46 -t 5700:3600 -g 0.8 -m randr -v it still stays on daylight even at night.

Thank you...

Ok after posting this I realized, that I need to use the -c option for the config file as;

redshift-gtk -c /home/foo/.config/redshift.conf

But I still don't understand why it didn't change from the cmd line as;

redshift -l 51.48:0.46 -t 5700:3600 -g 0.8 -m randr -v

Using the -c option for the config file I'm seeing a change, when I look at the Info it now says this;

Period: Transition (78.64% day)

I've tried both transition=0 & transition=1, then I commented it out ; but it still shows in the Info this Period:Transition and it takes a very long time, after 10 minutes it's only gone down 25%.

I thought the idea was to use `transition=0`` and when you run redshift it automatically switches to Night and with 1 it's going to go through this Transition?

Now I've got this thing finally doing something but it won't change automatically to night, it just slowly changes, how can I fix this?

I also ran it as; redshift-gtk -r -c /home/foo/.config/redshift.conf but it still says in the Info Period:Transition and it's still slowly creeping down... :(

It took 30 minutes to change, wow talk about a slow transition, so I don't understand these transition= options...

thanks

I'm back the next day and it's 7PM and it has not started to show it's doing a Transition to night...

The settings in the config I have above will this work?

location-provider=manual
lat=51.48
lon=0.46

Will redshift Transition from Day to Night with it on manual and setting the lat:lon?

thanks

Try to run

sudo hwclock --utc --systohc
sudo date --set "2014-08-11 14:10:16"
sudo date --set "2014-08-10 23:32:48"
sudo hwclock --utc --hctosys

while you have the info. dialogue open.
At 2014-08-11 14:10:16 it should say that it is daytime
(the Sun's elevation will be at 51,3°) and at 2014-08-10 23:32:48
it should say that it is night (the Sun's elevation will be at −20,3°.)

At 2014-08-11 19:00:00 it should say that it is daytime (the
Sun's elevation will be at 21,6°.) The transition to night
should start at 2014-08-11 20:01:46 for you.

All these times are in British Summer Time.

Use --localtime instead of --utc if you use
local time on your hardware clock.

-c ~/.config/redshift.conf should not be required,
that file is used by default. Simply run redshift-gtk.

HI maandree,

That isn't actually my LAT:LON I just put those up...

Sorry can you please explain why I would need to run these two cmds below?

Set the Hardware Clock to the current System Time?
sudo hwclock --utc --systohc

Set the System Time from the Hardware Clock?
sudo hwclock --utc --hctosys

Also why do I need to set the date as below?

sudo date --set "2014-08-11 14:10:16"
sudo date --set "2014-08-10 23:32:48"

By the way I need this to tranistion at 19:00, 20:00 is to late. By 19:00 I need the screen to start getting darker...

Ok man mentions -c so maybe man needs an update?

Ok I thought if I run redshift-gtk at night it's going to transition, but it's not?

What's odd is when I ran it as; redshift-gtk -c /home/foo/.config/redshift.conf it started to change, now I try it again and nothing, even as redshift-gtk...

If I remember correctly changing the lat lon, then restarting it caused it to finally change to night, hmm odd...

In the config If I have it set to; location-provider=manual and the lat= lon= set, then redshift should transition automatically?

thanks

sudo hwclock --utc --systohc
# Write the current time on the system to the hardware clock (store the clock)

sudo date --set "2014-08-11 14:10:16"
sudo date --set "2014-08-10 23:32:48"
# Set the current time on the system

sudo hwclock --utc --hctosys
# Write the current time on the hardware clock to the system (restore to clock)

-c can be used if you want to use another configuration file then
~/.config/redshift.conf. But perhaps that should be clarified as that
is only impled from the configuration file section.

You can change elevation-high and elevation-low to select when
the transition starts and begins by the Sun's elevation. But if you want
exact times that do not depend on what time of the year it is you
will have to use https://github.com/maandree/blueshift instead.

SORRY my bad, I understand the cmds, LOL, I'm only asking why do I need to run these?

Oh so this is going to transition by the suns elevation? Well it's 20:15 and this still hasn't changed... :(

Again I'm doing this manually; (So manually changes automatically)?

location-provider=manual
lat=51.48
lon=0.46

By the way I didn't see anything in the man regarding; elevation-high and elevation-low. Not sure how to use it?

There doesn't seem to be much documentation on redshift, or I'm not seeing/finding it... :(

P.S. I'm not using geoclue it's not compiled in, do I need it? it's now 21:25 and it's still saying Daytime, and I've edited and played around with the config several times, for the life of me I can't get it to start transitioning to night... :(

[maandree]

Appearantly we forgot to write about them, but you can read about them at
https://github.com/maandree/redshift/blob/f7b1dc4d21e3632838e24f95ab5dbdd66fc3946c/info/redshift.texinfo#L441-L453

elevation-high and elevation-low selects during which range of the Sun's elevation
the transition occurs. The Sun's elevation does not only depend of your location
but also on when time of the year it is. For example, during summer on the northern
hemisphere the North Pole will have daytime during all 24 hours, but during winter
it will always be night on the North Pole. Therefore if we set elevation-high to
20° the transition from day to night will start at 17:10:22 UTC on 2014-08-10 but at
23:48:14 UTC on 2014-02-09, if your location is 51,48°N 0,46°E.
(Edit: 23:48:14 feels improbable, maybe I goofed up my calcuation.)

SORRY my bad, I understand the cmds, LOL, I'm only asking why do I need to run these?

That makes more since than a slackware user not understanding those commands.
It was so that you could see if the info dialogue actually changed the period of the
day. But those values was based on your location, and because you are actually
asking for customised transition time that is not needed.

HA I am a Slacker too... LOL... :) Ahh miscommunication on my part, wasn't sure why you wanted me to run them...

Sheesh this thing is starting to finally transition at like 22:00, and it completed at like 22:30. Arggh that's way to late...

19:00 Winter is when I need it to transition
19:30 Summer is when I need it to transition

Does Daylights Savings in the USA matter? Because we don't use it.

Something must be wrong with this to transition so late?

[maandree]

HA I am a Slacker too... LOL... :)

That was what I said, or at least meant to, personally I am an Archer.

You should use lon=-0.46, a negative value indicates that you
are on the west side of GMT, and whilst a positive value indicates
that you are on the east side of GMT. Really common error.
We actually recently #90 so
one would easier catch an error like that. Are you using
the tagged release (where you cannot see this) or are downloading
the source directly from git (where you can see this)? If you are
can see this I guess we have to make it stand out more somehow.

Redshift is oblivious to timezones it uses UTC only, so daylight savings
time and misplaced timezones (their are quite a lot of timezones that
are off by one hour compared to what one would expect) have not
affect.

Ok Archer, hehe, I've used Arch quite a bit, I like it... :)

Ahhh the negative symbol - I didn't know that. I just looked at my location at; wunderground.com and copied what I saw. Might be nice to mention that in the man page on a next update.

I'm using 1.9.1, but I don't notice anything in the 'Info' to help me spot this, not sure about what you're asking if I see? I see now the negative symbol appearing in the Info.

In the meantime I'll make this negative and see how that goes.

THANKS

[maandree]

Okey, then you are using the latest released version and should not see anything,
in the development version the info dialog and -v switch use N/S and W/E rather than
- for S and E.

I will keep the negative, but I will edit the values.

Ok...

And now it worked and changed at 19:00

YEAH! :)

Thanks heaps and keep up the great work! :)

[maandree]

No problem. Don't forget to the coordinates you too have written.

Yes I must not let them find me! LOL... ;)

Cheers
