For the longest time, I couldn’t figure out how to get my wireless to on my laptop. I could enable and disable my wireless card, but I could never scan and view available wireless channels. After searching many forums, I came across an article that suggested this.

rfkill unblock all

After you run this command, disable and enable your wireless card. If your problem was similar to mine, then you should be able to see wireless channels and connect. I’m not sure exactly why this works, but it worked for me. Feel free to explain if you know why this solution works. I am curious.

I hope this helps someone out. I’m very thankful I was able to come across the solution.

Ok, so twice I had to research and figure out how I got the symbol browser working in gedit. I started out trying to install the Class Browser. But the ubuntu community suggested that this plugin was no good and to instead use the symbol browser. If you quickly rush and start downloading the symbol browser plugin, you will find that you just downloaded a whole bunch files that need to be compiled. Lucky for us though, you can instead download the binary files for the symbol browser. Go to SourceForge and instead of clicking on “Download Files”, look below under “Browse Files for Gedit Symbol Browser Plugin” and you should see

gedit-symbol-browser-plugin-bin-ubuntu-i386-0.1.tar.gz

If you are using 64 bit, make sure download the 64 bit binary version.

Extract your files and move it over to ~/.gnome2/gedit. You should have the following files…
~/.gnome2/gedit/symbols
~/.gnome2/gedit/plugins/libsymbolbrowser.so
~/.gnome2/gedit/plugins/symbolbrowser.gedit-plugin

A lot of us will now try and open Gedit and enable the plugin. As you try, it will automatically get grayed out. This is because you need the following package.

libgnomeprintui

Once you restart Gedit and enable the plugin, you might realize that it’s still not displaying any class, functions, or variables after you open a file. This is because you need to install exuberant-ctags. After you do this, you should be ready to go.

Let me know if you have any problems.
