Everything works on my laptop except Bluetooth

This is pretty weird. Bluetooth worked fine under Win XP. The computer is an HP/Compaq nc8430. When I go to the Bluetooth control panel I get “Your computer does not have any Bluetooth adapters plugged in.” The weird thing is, sometimes I’ll see the bluetooth logo in the taskbar at the top, but then when I look again it’s gone and I have no idea how to get it back. When I booted it up this morning I noticed the icon was there so I ran some of the debugging tools for Bluetooth and checked dmesg and this time at least it looks like at least there’s proof that Linux CAN see the Bluetooth adapter, I just don’t get why it then stops recognizing it after just a minute or two, and a reboot doesn’t even consistently bring it back.

How to install the 64-bit Sun Java plugin on 64-bit firefox on 64-bit Fedora Core 11 Linux (which happens to use 64 bits)

I’m giddy! I found this post on mozdev.org which was magical.

[evan@ehoffman ~]$ java -version
java version "1.6.0_17"
Java(TM) SE Runtime Environment (build 1.6.0_17-b04)
Java HotSpot(TM) 64-Bit Server VM (build 14.3-b01, mixed mode)
[root@ehoffman plugins]# uname -a
Linux ehoffman 2.6.30.8-64.fc11.x86_64 #1 SMP Fri Sep 25 04:43:32 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux
[root@ehoffman plugins]# pwd
/usr/lib64/mozilla/plugins
[root@ehoffman plugins]# ln -s /usr/java/jdk1.6.0_16/jre/lib/amd64/libnpjp2.so

The main thing I was missing was that the plugin isn’t libpluginjava_oji.so, or whatever I thought it was, but libnpjp2.so. Once I created the symlink into /usr/lib64/mozilla/plugins it worked (as verified on http://www.java.com/en/download/help/testvm.xml and http://www.java.com/en/download/installed.jsp).

That’s all it takes to get the Sun Java plugin working in Firefox on Linux.
