f.lux or something like it?

Post by in2itiveart »

Hi -
I am a newbie - i just got a new laptop with linux yesterday after years on macs. I would like something like f.lux and have seen it on github and at justgetflux.com but I don't know how to download it - or install it - does someone know if there is a similar program or have the link to download it and perhaps install instructions? thanks...

Redshift is pretty much the same thing. What is your exact version of Linux Mint? You may already have it installed.

I don't know - I want to say 18.1 - but not sure. Not sure how to find that out. Will look into it. I did search for redshift and came up with nothing. thanks!

So can you please post the result of the following terminal command, and enclose it in code tags? That's the button marked </>.
This is needed for pretty much any question about your system, so it's a good habit to post it straight away.

Code: Select all

inxi -Fxz
Also, *how* did you search for Redshift?
If it's not installed you can easily install it from the Software Manager; you will want both Redshift and Redshift-gtk, to give it a graphical interface.

Type the follow in a terminal

Code: Select all

inxi -Fxz
It will tell you which desktop your using.
You can install fluxgui from the ppa or use redshift both work well fluxgui has easier control of color shift IMHO.
fluxgui PPA : https://github.com/xflux-gui/fluxgui
Scroll down until you see this line copy and past it to a terminal hit enter:

Code: Select all

sudo add-apt-repository ppa:nathan-renniewaldock/flux
then copy and paste the other lines one at a time. Good Luck.

Definitely redshift! Absolutely amazing program. I used to be a big fan of f.lux, then I found redshift, which actually gives you much more control. :)

And no PPA needed, which is always a plus.

Hi - i have gone to my software manager and searched for Redshift. I have "installed" it supposedly, but it is not operating. I have never typed anything into a terminal in my life and don't want to mess anything up - I don't get this at all coming from using macs for the last 20 years... so - I guess I will have to bite the bullet and type some stuf into the terminal but i would like alittle more instruction. thanks!

Just type redshift in the terminal if it's installed it should come up.
It's usually found int the menu under Accessories. good luck

Did you also install Redshift-GTK, like I recommended? That should give the software a GUI (Graphical User Interface). Without that, it needs to be started from the terminal. Personally I like software to have a GUI.

Yup, what kc1di and Moem said. :) The GUI is quite nice. Fun fact: the Mac has terminals too, which operate very much like ones in Linux.

Honestly, - I have never had to use a terminal before so it scares me, so I am learning. I had to leave yesterday after I posted this - so I did not get it done. I amtrying again today. I searched in software manager. I found both gtk and redshift. installed them and then got an error message which said "failed to run redshift Trying location provider `geoclue2'...
Unable to connect to GeoClue.
Unable to get location from provider."

I am still working on it. when it is solved I will type that it is solved.

Thanks.

I am not going to follow the terminal command by myself. I am going to get a friend who is a developer to show me how to do that - probably next Sunday. sorry to be such a nube.

Okay, that's a thing we can fix, thank you for giving the error code.
Usually, that means Redshift becomes active before Geoclue has any location information to offer, and Redshift needs to know where you are so it knows when to change the colour of your monitor. We can fix that without using the terminal at all, by going to Startup Applications (it's on the menu) and giving Redshift a bit of a startup delay. I'd go with 10 (seconds) to be on the safe side.

Hi, I also just installed Redshift and Redshift-GTK.

Am I correct in assuming there is no need for Plasma-widget-redshift or Plasma-applet-redshift-control if the default settings are acceptable. Sounds like these allow more customization of it? Also no need for Gnome-shell-extension-redshift?

This suggests a different solution if that error occurs: https://itsfoss.com/install-redshift-linux-mint/

(I did not get the error myself, but don't see a delay option for start-up in XFCE)

I don't have any of those so I'd say you're assuming correctly.

Redshift plasma-applet is for those running the KDE plasma desktop - and the other is for gnome desktop so you should not need either for it to run and work on xfce.

Hope it's working for you :)

You could add a delay for execution of a command by using sleep.
You can just add sleep n ; before the command in order to delay its execution for n seconds.
For Redshift, it could look like sleep 10 ; redshift-gtk, if you want to postpone its start with 10 seconds.
