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.

Here’s what lspci -nn showed while the it was up:

When I did “hcitool dev” it actually showed something:

[root@ehoffman ~]# cat hcit.dev
Devices:
	hci0	00:16:41:BA:C6:xx

Here’s where it looks like it started working and then stopped working from /var/log/messages:

It looks like it worked until I turned on wireless via the hardware switch. But even if I start up with wireless off it doesn’t work. Hmm.

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

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.
