[qubes-users] Re: Qubes i3 Tips & Tricks

[Daniel Moerner]

A quick follow-up on this:

First, I have a branch with i3 updated to 4.16.1 for testing: 
https://github.com/dmoerner/qubes-desktop-linux-i3/tree/4.16.1-colors. I 
believe it is now stable. (cf. 
https://github.com/QubesOS/qubes-issues/issues/5168)

Second, a nice, lightweight redshift program for dom0 is sct: 
https://www.umaxx.net/dl/sct-0.4.tar.gz. This is written by a few OpenBSD 
developers and is so simple you can audit the C code yourself before 
installing it in dom0. It isn't in Fedora yet, although I will get around 
to pushing it eventually 
(https://copr.fedorainfracloud.org/coprs/dmoerner/sct/).

Third, a question: Some of the icons in the domains.py and devices.py tray 
icons don't appear by default. They do appear if you run "xfce4-settingsd". 
It has something to do with populating the default icons. I haven't been 
able to figure out how to get it to show icons without running 
xfce4-settingsd. I tried some basic settings in ~/.gtkrc-2.0 and 
~/.config/gtk-3.0/settings.ini, without any luck. If anyone knows how to do 
this, that would be nice to hear. I prefer not to use "xfce4-settingsd" 
since it seems to mess up some of the i3 hotkeys.

By the way, if anyone is using awesome: You might want to install 
i3-settings-qubes. qubes-i3-xdg-autostart is a simpler alternative to 
dex-autostart, and qubes-i3-sensible-terminal works great with awesome.

Best,
Daniel

I can confirm that the following works for keeping the Tor Browser in
it's initial default state. Might be more convenient for users using
other tools in Whonix that just the browser.

for_window [class="Tor Browser"] floating enable
