That's not my screenshot, but it is
x11-wm/fluxbox. There are plenty of mine in the screenshot thread and they all look the basically same sans wallpaper. He's using one of the default Fluxbox styles, bora black, with rounded edges. I use my own 8ball B&W style with square edges otherewise mine would look the same. (His are inconsistent. If you notice the corners on his app title bar are rounded, the menu ahd taskbar have square corners.)
Add it to your
/usr/home/username/.xinitrc file as the last line like this. I have other programs start with boot so I'm ready to go:
Code:
Eterm &
gkrellm &
xfe &
fluxbox exec
Use
startx
from your user account at the login terminal.
The menu is located at
/usr/home/username/.fluxbox/menu and you need to manually add the programs you've installed with a text editor. If the text editor you're looking for isn't already listed on the menu invoke it through the terminal from your user account, not your root account, and add it. There are already examples there you can work from, just watch that your markup syntax stays in sync so you don't lose a sub-menu.
Styles go in
/usr/local/share/fluxbox/styles and I have a few available on my site you can use and modify with a text editor to your taste. The rest is all done through the right-cliclk menu.
There's really nothing hard about it but I'll be glad you answer any questions if you have a problem with it.
