Note 1: in the time of this writing, this didn't include what is documented in the GNU Guix installation instructions[1] and application setup[2] nor what GNU Guix recommends after installing other applications through it.
Note 2: after my final bachelor's degree work I might turn this into a wiki page here in Trisquel or a blog post in GNU Guix project's page. * Make desktop menu entries and themes from GNU Guix appear in Trisquel 1. Copy the current contents of $XDG_DATA_DIRS variable, this can be done with: echo $XDG_DATA_DIRS Then copy the result; 2. Inside the "~/.profile" file, after the line that begins with "#umask 022" and preferably after the other variables that you have defined for use with GNU Guix, add the following line: -------------------cut here---------------start------------------ export XDG_DATA_DIRS="$HOME/.guix-profile/share:[Content copied from step 1, without these braces.]" -------------------cut here---------------end-------------------- 3. After this, log out and back in to your user's session (no need to reboot the computer); Technical important note: Trisquel's upstream still uses faulty Xsession.d scripts, thus we cannot simply use the GNU `bash' paramenter expansions such as `${VARIABLE:+:}$VARIABLE' because before starting the desktop session that variable isn't set. At the same time, we can neither do if/else checks to set it. If we do any of these, we would always be creating that variable, and the faulty Xsession.d scripts would not make the desktop session start, because the ".profile" is read before starting the desktop session, the Xsession.d scripts are read after .profile and before starting the desktop session, and these scripts do nothing (don't set the needed variables) if the $XDG_DATA_DIRS is found to be already set. * Applications which use GTK have missing objects, colors or lines 1. Go to: Trisquel menu → System → Preferences → Visual and behavior → Appearance (or Look); 2. Go where the current theme is ("Trisquel" by default which is also the recommended), and click on the button to customize it; 3. Go to: Controls; 4. Select one of: Clearlooks, Crux, HighContrast, Industrial, Mist, Redmond, ThinIce. Side-effect: the task bar text will be black and thus hard to see with the default background or bar color. Important: this is only a work around, as the issue seems to be that newer packages installed through GNU Guix ignore some CSS declarations which are defined by the Trisquel theme. My limited knowledge leads me to think that the correct fix should be to change those declarations instead. * Make text fonts installed from GNU Guix appear in Trisquel packages Note: this fix only applies to packages that use the Fontconfig library. 1. Make this directory: "~/.config/fontconfig"; 2. Create the following text file: "~/.config/fontconfig/fonts.conf". I assume this doesn't exist. If it does, then you might need to fine tune the configuration order that I'll give in the following steps; 3. Note that the following step might not be visible in the forums, if so use the mailing list archives for trisquel-users and view this message there. Inside that file, add: -------------------cut here---------------start------------------ <?xml version="1.0"?> <!DOCTYPE fontconfig SYSTEM "fonts.dtd"> <fontconfig> <dir>~/.guix-profile/share/fonts</dir> <include ignore_missing="yes">~/.guix-profile/share/fontconfig/conf.avail</include> </fontconfig> -------------------cut here---------------end-------------------- The important parts here are the `dir' and `include' elements. The others are only useful for the cases when no "fonts.conf" file exists; 4. Run: FC_DEBUG=1024 fc-cache -vf You can also pipe it to GNU `less' (like: `FC_DEBUG=1024 fc-cache -vf | less') and use the / key to search for ".guix-profile/share/fonts" and ".guix-profile/share/fontconfig". If you do have fonts installed through GNU Guix, these two searches should respectively tell you if font files are being found and if their special classification and attributes are being recognized through their configuration files. Now, for example Trisquel's GIMP will find fonts installed through GNU Guix.
