This version of ddlabm07 (same code) was compiled for linux
either in ubuntu 11.04 or ubuntu 6.06.

I have found that the 6.06 version runs on my 11.04 laptop,
but the 11.04 version does not run on my 6.06 laptop because of library issues.
The error message is... "/lib/tls/i686/cmov/libc.so.6: version 'GLIB_2.4' not found"
but this may not apply to your linux op and computer.


Both compiled versions are available,
ddlab_linux11_July_2011.tar.gz (ddlabm07_Linux11) 
ddlab_linux6_July_2011.tar.gz  (ddlabm07_Linux6)

Another option if problems arise is to compile the code provided in
ddlab_code_July2011.tar.gz
------------------------------------

To run DDLab, open a terminal - from the directory with the DDLab files,
enter "./ddlabm07_Linux &".

Alternatively, If the files in "ddextra" (a separate download) are in
a sub-directory called say "ddfiles" then from "ddfiles" enter
"../ddlabm07 &" to start DDLab. This will keep files generated by
DDLab in this separate directory.

---------------------------------------------------
font issues in recent linux ubuntu (version 9.04 and later ?):
--------------
Recent versions of ubuntu no longer have 
xorg.conf (see below for the xorg.conf setup).
The fonts required by DDLab may or may not be available on your system.
In case not, the fonts are in directories: 100dpi, 75dpi, misc, 
which are in the file fonts_dd_linux.tar.gz, 
which can be downloaded from www.ddlab.org/download
These directories should then be placed in /usr/share/fonts/X11/

This works on my laptop with ubuntu 11.04 in KDE
There is no longer an issue to keep the contents of DDLab when
changing windows or workspaces (desktops), 
as long as "Desktop effects" are active.
---------------------------------------------------
  
font issues for older linux versions:
--------------
You might need to modify (as root) the X11 config file,
which has a different name for different versions of Linux:  
SuSe (and RedHat?): /etc/X11/XF86Config
Ubuntu (Kubuntu):   /etc/X11/xorg.conf

1. FontPath:
   in section "Files"
   you will see various FontPath(s) listed.
   if any of the FontPath(s) below are missing, they
   must be added, otherwise DDLab could crash.
   Again, the path differs for different versions of Linux.

   for SuSe (and RedHat?), add the following (if missing)
   FontPath      "/usr/X11R6/lib/X11/fonts/misc"
   FontPath      "/usr/X11R6/lib/X11/fonts/75dpi"
   FontPath      "/usr/X11R6/lib/X11/fonts/100dpi"
   
   for Ubuntu (Kubuntu), add the following (if missing)
   FontPath      "/usr/share/X11/fonts/misc"
   FontPath      "/usr/share/X11/fonts/75dpi"
   FontPath      "/usr/share/X11/fonts/100dpi"

   also, for ddlab to work on the GNOME desktop, add (if missing) 
   FontPath      "unix/:7100"


2. BackingStore - to keep the contents of DDLab when changing/hiding 
   windows, the following should be in the config file,
   in Section "Device" (not Section "InputDevice")
   you will see various things listed,
   add: Option "BackingStore"
   i.e.
   Section "Device"
        Identifier   "Neomagic Corporation|NM2360 [MagicMedia "
        Driver       "neomagic"
        BoardName    "Unknown"
        Option       "BackingStore"
   EndSection

   However, if you switch workspaces (desktops) in KDE or GNOME
   the previous images in the DDLab window will be lost.
   In FVWM this problem does not occur.
