I’m assuming that you already have Cygwin installed. If you don’t, you can get it from here. In addition to whatever other packages you have selected to customize your install, you also need development packages (gcc and friends), Xorg packages (headers, includes, and libraries), and a few graphics libraries (for aterm):

• Devel
  • gcc-core
  • gcc-g++
  • libXaw3d-devel (for xv)
  • libjpeg-devel (for aterm)
  • libpng12-devel (for aterm)
• Libs
  • jpeg (for aterm)
  • libXaw3d-devel
  • libXaw3d-7
  • libfreetype6
  • libjpeg-devel
  • libjpeg62 (for aterm)
  • libjpeg6b (for aterm)
  • libpng12 (for aterm)
  • libpng12-devel (for aterm)
  • libtiff5 (for aterm, xv)
  • zlib-devel (for aterm)
  • zlib0 (for aterm)
• Utils
  • bzip2 (to handle .bz2 files)
• X11
  • libX11-devel
  • xinit
  • xsetroot (if xv doesn’t work for you)

After Cygwin finishes installing those packages, grab the sources for libAfterImage, aterm, and xv. Unpack the sources perform the requisite steps to build and install from source (./configure, make, and make install should work if all goes well).

libAfterImage:

If you get “parse error before XErrorEvent” errors while building libAfterImage, make sure that you didn’t forget to select the X11 development package.

aterm:

gcc on Cygwin expects –rdynamic and not -rdynamic. If you’re seeing these errors, edit the Makefiles under src and src/graphics within the aterm source directory. Change the “-rdynamic” to “–rdynamic”. The changes should be on line 54 for both files.

xv:

Under the tiff directory within the xv sources, there is a file called RANLIB.csh. Edit this file and make sure that you ONLY have the following line in there:

ranlib $1 >& /dev/null

Otherwise the build process will fail. Additionally, you need to edit xv.h. This file lives right at the root of your xv source directory. If you do not perform the following change, you’ll get errors from gcc complaining that “sys_errlist has previously been defined”. Change line 119 of xv.h to:

/*extern char *sys_errlist[]; */    /* this too... */

What you’re doing is commenting out the definition for sys_errlist so that it doesn’t conflict with what has already been defined in the Cygwin header files. These changes should be the only ones you need to get xv compiling and running.

Now you need to set up two batch files. One to start up X rootlessly, and another to start up aterm. Before you do that, make sure you add C:\cygwin\usr\bin and C:\cygwin\X11R6\usr\bin to your PATH variable. You can do this by going to My Computer > Properties > Advanced > Environment Variables. If you don’t do this, you’ll get “cygwin1.dll not found” errors while trying to run these batch files. The X windows binaries used to live in C:\cygwin\usr\X11R6\bin, but have since been moved to C:\cygwin\usr\bin. Therefore, the start-up batch-file now looks like this:

xwin.bat:

C:\cygwin\usr\X11R6\bin\run.exe C:\cygwin\usr\bin\xwin.exe -multiwindow -clipboard -silent-dup-error
C:\cygwin\usr\X11R6\bin\run.exe C:\cygwin\usr\local\bin\xv.exe -display :0 -root -quit -be -max /cygdrive/c/Documents\ and\ Settings/vivin/My\ Documents/My\ Pictures/Wallpapers/01707_spectrumofthesky_1920x1200.jpg

The first line starts up the X windowing system. The second line sets the wallpaper using aterm. You now need another batch file to run aterm, and that looks like this:

aterm.bat

C:\cygwin\usr\X11R6\bin\run.exe C:\cygwin\bin\bash.exe --login -i -c "aterm -sh 80 -tr -trsb -fade 20 -tint gray -sb -st -sr -sl 1000 -tn xterm"

This file starts aterm with the background image at 50% brightness, transparent background, transparent scrollbar, 20% fading on losing focus, gray tint, scrollbar, trough-less scrollbar, scrollbar on the right, 1000 scrollback lines, and with xterm terminal emulation. Like I mentioned in my original guide. xv will sometimes fail to start with xwin. If that is the case, you can modify aterm.bat to look like this:

aterm.bat:

C:\cygwin\usr\X11R6\bin\run.exe C:\cygwin\bin\bash.exe --login -i -c "xv -display :0 -root -quit -be -max /cygdrive/c/Documents\ and\ Settings/vivin/My\ Documents/My\ Pictures/Wallpapers/01707_spectrumofthesky_1920x1200.jpg && aterm -sh 80 -tr -trsb -fade 20 -tint gray -sb -st -sr -sl 1000 -tn xterm"

Slightly inefficient, but it works. Now if you have a dual-monitor display, you’ll notice that the background image is stretched across both screens when you run aterm. This is probably not what you want. To fix this problem you need to change a few invocation options for xv. For this to work properly (meaning, not look crappy) both screens should be running at the same resolution:

xv -display :0 -root -quit -be -maxpect -rmode 1 /cygdrive/c/Documents\ and\ Settings/vivin/My\ Documents/My\ Pictures/Wallpapers/01707_spectrumofthesky_1920x1200.jpg

Notice the -maxpect and -rmode 1 options. -maxpect expands the image to fill the screen while maintaining the aspect ratio, while -rmode 1 sets the display mode on xv to tiled. So you should now have your wallpaper displaying on both screens now (under X) without being distorted.

Here’s what it looks like on my machine:

This is on a dual-monitor setup with both screens running at 1920×1200 resolution. I’ve set X’s background to be the same as my windows Wallpaper so that it looks cooler. Notice how the background image (inside aterm) is not stretched, but tiled across the two screens. That’s all there is to it. Seems like a bit of work, but I think it’s worth it. My main reason for going through all this trouble was to get a decent terminal running in windows. I guess I could have just used xterm, but aterm looks so much nicer, doesn’t it?

On any system that I plan to use for an extended period of time, I will always install Cygwin. This is mainly because I like have UNIX tools on Windows, and also so that I can use the console to do things that DOS is not able to do. I started using Cygwin in 2000, and I’ve continued using it since. One of the cool things you can do with Cygwin is run X, which means that you can have X applications running on the Windows desktop. When I was interning at Motorola, I used to run eXceed, with fvwm. This was where I first ran into aterm. What I liked most about aterm is the eye-candy. You can have transparent windows with shading effects and all sorts of other cool stuff. I tried to get aterm running on my machine at home by compiling it from source under Cygwin. I was eventually able to do this (install libjpeg, libpng, libAfterImage, zlib, and the X includes and libraries first), but what I didn’t like was the fact that you had to start up a Cygwin console to open up X, and then aterm. I wanted aterm to start up and run directly without that ugly DOS/Cygwin console window. Of course, you can’t simply run the aterm executable because it needs X and Cygwin to be running. I eventually figured it out (actually a few months before leaving on my “extended vacation”) by starting out with X running with a rootless window. Oh, and run.exe proved to be very helpful. Anyway, here is how you do it:

First you need to add C:\cygwin\bin to your PATH Environment Variable. You can do this from My Computer > Properties > Advanced > Environment Variables. You might also have to add C:\cygwin\usr\X11R6\bin to PATH.

Then you need to create two batch files. The first one is to start X, and the second one is to start aterm (or whatever X app you want to start). The example I’m going to show includes starting up X with a wallpaper (using xv), and then running aterm. I run aterm with a transparent background, using the X wallpaper. However, you can also load aterm with a background image of your choice.

The batch file to start X, which I call xwin.bat looks like this:

C:\cygwin\usr\X11R6\bin\run.exe C:\cygwin\usr\X11R6\bin\xwin.exe -multiwindow -clipboard -silent-dup-error
C:\cygwin\usr\X11R6\bin\run.exe C:\cygwin\usr\local\bin\xv.exe -display :0 -root -quit -be -maxpect /cygdrive/c/Wallpapers/upper_limit_wp_dark_1600.jpg

This will start up X in a rootless window with upper_limit_wp_dark_1600.jpg as your X wallpaper. Next, you write a batch file (aterm.bat) that will load aterm:

C:\cygwin\usr\X11R6\bin\run.exe C:\cygwin\bin\bash.exe --login -i -c "aterm -sh 50 -tr -trsb -fade 20 -tint gray -bl -sb -st -sr -sl 1000 -tn xterm"

This batch file will load aterm with the background image at 50% brightness, transparent background, transparent scrollbar, 20% fading on losing focus, gray tint, borderless window (sometimes works), scrollbar, trough-less scrollbar, scrollbar on the right, 1000 scrollback lines, and with xterm terminal emulation. One issue I have had with this, is that aterm may load up with the default (checkered) X background. This is because the xv did not properly execute in xwin.bat. I have no idea why this happens, sometimes it works, and sometimes it doesn’t. If it doesn’t, you can modify aterm.bat:

C:\cygwin\usr\X11R6\bin\run.exe C:\cygwin\bin\bash.exe --login -i -c "xv -display :0 -root -quit -be -max /cygdrive/c/Wallpapers/upper_limit_wp_dark_1600.jpg && aterm -sh 50 -tr -trsb -fade 20 -tint gray -bl -sb -st -sr -sl 1000 -tn xterm"

This batch file will load xv every time you start aterm, so there is a slight performance hit on startup. However, it’s not that big of a deal because the xv instance quits right after it sets up the wallpaper, and so you’re not loading a new instance of xv into the memory every time.

Well, there you have it. I hope it was helpful!
