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.

Enabling touchpad clicking and edge scrolling in Squeeze

Gnome has a mouse configuration interface that lets you enable touchpad clicking and scrolling. But if you are a Debian Squeeze user and prefer Xfce, LXDE, or some handmade alternative, you will find that your touchpad's clicking and edge scrolling won't work [1]. You'll also find that those functions don't work in the GDM login screen even if you do use Gnome. No probs. The fix is easy.

To fix:

1. Open  /usr/share/X11/xorg.conf.d/50-synaptics.conf (as root) in an editor.
2. Add the text
Option "TapButton1" "1"
Option "VertEdgeScroll" "1"
   between Section "InputClass" and EndSection.
3. Save, reboot and enjoy.

Note that if you use Gnome, you might find that your old mouse settings are messed up after the above. Set them again and all should be fine.

If you don't like the idea of changing system config files, you can use synclient in a startup script to enable things as well.

(No) icons in GTK buttons

I don't know if this has anything to do with the no icons in menus issue, but the solution is darned near the same. I noticed that my Ubuntu Karmic doesn't serve up icons in its buttons with GTK apps in GNOME. The fix comes from someone trying remove his icons:

There is now a new key in GNOME Configurator Editor. Below are the steps to disable buttons on icons in GNOME 2.26 and above.

1. Press Alt + F2
2. Type gconf-editor and hit Enter.
3. Go to Desktop –> GNOME –> Interface
4. Uncheck the key buttons_have_icons

Just check the box to get your icons back.

Running commands on GNOME logout

This post deals with GNOME, which disqualifies it from any reasonable "light-and-lean" discussion, but I don't exactly know where else to make a note of this.

One of the bigger omissions from GNOME is that there is no built-in mechanism for executing commands at logout. I discovered this the hard way when trying to set up MPD to run completely in userspace (to be documented in an upcoming post). However, it is possible to make GDM run arbitrary stuff at the end of the session, and that can be used to good effect as described here. In the event that that link goes bad, in summary what you do is edit /etc/gdm/PostSession/Default
and add

logoutscript="$HOME/.gdmlogout";
if [ -x "$logoutscript" ] ; then
su $USER -c "$logoutscript"
fi

to the file. Then create a file .gdmlogout in your home directory and make it executable.

You need to note that this will only work if you are using GDM and the .gdmlogout file will execute no matter what desktop environment you log into.
