+
+This directory contains file to test the desktop following the idea from
+<https://guix.gnu.org/de/blog/2019/running-a-guix-xfce-desktop-on-centos-7/>.
+The basic idea: Start an X11 server (provided by the host OS) on another
+virtual terminal and make this run the desktop.
+
+See comments in desktop-manifest.scm for which packages get installed and what
+combinations I already treid.
+
+
+
+Brief howto
+=================
+
+* Switch to a new virtual terminal (e.g Ctrl-Alt-F2) and login there
+  (maybe this is not necessary, but I was not able to start a new X11 server
+  from within my running X session)
+
+* cd here
+* Adjust desktop-manifest.scm
+* Adjust .xinitrc
+
+* Run ./00-setup.sh
+
+  This script will set this directory as your HOME, create a Guix profile
+  containing the Plasma desktop and start the X11 server with the Plasma
+  desktop on the next virtaul terminal.
+
+* check results, refine packages, adjust desktop-manifest.scm redo :-)
+
+* new X-server will get DISPLAY :1.
+  To change this, change number at the end of 00-setup.sh  and 01-setup.sh
+
+
+Files
+============
+
+00-setup.sh  - starts using a profile - might require tweaking
+01-setup.sh  - starts using an environment - unfinished
+desktop-manifest.scm - packages to install.
+             Also contains information about what I already tried.
+
+.xserverrc  - starts X server on next vt - called by xinit
+.xinitrc    - start the X clients, esp. the desktop
+              Use these scripts to be more flexible in adjusting environments
+
+xorg.conf  - unused in the Plase desktop test playground. *-setup.sh uses the
+             host OS's xinit and the host OS's xorg.conf
+
+unstrace.py  - unfinished helper to strip irrelevant information from
+ 	       the strace logs
+
