redshift or brightness control?

[rec wins]

hello, is there a way to install and use redshift or any brightness
control for dom0, which I assume is where the package would have to go,
I get blinded in the evening, and manually changing monitor brightness
isn't practical.... TIA

That's right, you have to install it to dom0 (on your own risk). Just run
$ sudo qubes-dom0-update redshift
in dom0. (add also redshift-gtk for gtk-support.

I was under the impression , esp since dom0 is Fedora 25 to "never
install anything" in dom0 but OK,

is/are there any other helpful utilities people install in dom0 that are
"safe"

I second redshift. I also like having a graphical text editor.

It's true that Qubes warns against adding packages to dom0, but the choice is yours. I
rarely install anything to dom0, but when I do I only choose well-known packages with few
or no dependencies.

so $sudo dnf install redshift-gtk ?

seems to not be the package name , hmm

The dnf command is only used for removing packages.

do you invoke it from command line? if so, may I ask with what command
argument ?

via xfce menu "failed to run redshift, trying location provider
'geoclue2' ,

maybe because dom0 has no access to the world or something ?


sorry if this might be more redshift-y than qubes-y

I invoke it via the session and startup preferences in system tools, so it loads every
time Qubes starts. There's an also an entry in Dom0's application menu.

That's right. Geoclue2 won't work, but you can set the provider to "manual" and enter
your location coordinates. You can put those settings in a file at
~/.local/redshift.conf. See the redshift man page for all the options.

No worries, I had the same problem myself at one time.
