XDG menus in Openbox

Now I feel stupid. For year(s) I've been sorta griping about how the Openbox menu doesn't give you a program listing that coincides with what you get in GNOME, Xfce, and even fbpanel. I've hunted for solutions to this before but came up short. Turns out the solution is insanely simple.

The following is a direct quote from from the excellent ArchWiki. I tried it in Ubuntu Maverick and it works.

Obm-xdg

obm-xdg is a command-line tool that comes with Obmenu. It can generate a categorized sub-menu of installed GTK/GNOME applications.

To use obm-xdg, add the following line to ~/.config/openbox/menu.xml:

{menu execute="obm-xdg" id="xdg-menu" label="xdg"/}

(note: the curly brackets above should actually be angled brackets, but this crazy Blogger interface makes it close to impossible to write the above with angled brackets.)

Then run openbox --reconfigure to refresh the Openbox menu. You should now see a sub-menu labeled xdg in your menu.

Note: If you do not have GNOME installed, then you need to install gnome-menus package for obm-xdg to work.

Update: This is having issues on Squeeze. More later as I (if I) figure it out.

Java Swing anti-aliased font rendering

[Update 2011-04-03:  The Arch Wiki describes lots of options for the export below. I've been having good results with export _JAVA_OPTIONS='-Dawt.useSystemAAFontSettings=setting']

Today I noticed fonts in my Swing-based Java apps were utterly hideous. They were no longer being rendered with anti-aliasing. I don't know if this is because today I logged into a minimal Openbox+fbpabel setup and GNOME was handling this automatically or if it's caused by some other subtle thingy.

No matter, it's pretty easy to fix. Add

export _JAVA_OPTIONS="-Dawt.useSystemAAFontSettings=on"

to your ~/.profile file. You'll probably then have to logout and back in. After this anti-alised rendering will be the default.

Supposedly, you can do this system-wide by adding

_JAVA_OPTIONS="-Dawt.useSystemAAFontSettings=on"

to your /etc/environment file, but I have not tried this.

Update There is one downside to this: the JVM will write Picked up _JAVA_OPTIONS: -Dawt.useSystemAAFontSettings=on to the console. It's not a deal-breaker, but it is a little annoying.
