Fedora 15/Satellite P750 Bluetooth issue
Category: linux
Where on earth is the bluetooth??! According to:


systemctl status bluetooth.servicebluetooth.service




- Bluetooth Manager
     Loaded: loaded (/lib/systemd/system/bluetooth.service)
     Active: active (running) since Thu, 13 Oct 2011 21:06:35 -0400; 43min ago
    Main PID: 1027 (bluetoothd)
     CGroup: name=systemd:/system/bluetooth.service
         â”” 1027 /usr/sbin/bluetoothd -n



But the bluetooth gui says:

No Bluetooth adapters found



I am stumped. Is there a hardware switch to the bluetooth that is turned off?

rfkill list
0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no



The bluetooth is not even there.

Gaaaah!!

Some more googling lead to this thread:
Keany says:

before you start BT installation be sure WLAN LED is ON.



Hmm... so the WLAN LED is on, but the Bluetooth LED is not on and there is no function key to turn the bluetooth LED on!

Aarrrgh. Another unsolved mystery.

Texmaker error in Fedora 15
Category: linux
Escapist solution to ensuing mess:
The wrestling match with Texmaker on Fedora 15 got way too confusing. I found that Texmaker has a fork called Texstudio and I have installed it instead. The x86_64 version of Texstudio for Fedora 15 is available here:

My most useful LaTeX editor doesn't start in Fedora 15. I am getting this error message:

texmaker: error while loading shared libraries: libQtWebKit.so.4: cannot open shared object file: No such file or directory



But I do have libQtWebKit.so.4!

whereis libQtWebKit.so.4
libQtWebKit.so: /usr/lib/libQtWebKit.so.4



After some googling, I think the problem lies here:


whereis libQtGui.so.4
libQtGui.so:
/usr/lib/libQtGui.so.4
/usr/lib64/libQtGui.so.4



To try and find out which one of these is "owned" or "required" by other packages, I used the syntax from this VERY helpful document:

rpm -qf /usr/lib/libQtGui.so.4


gives

qt-x11-4.7.4-2.fc15.i686



rpm -qf /usr/lib64/libQtGui.so.4


gives

qt-x11-4.7.4-2.fc15.x86_64



Just for kicks, I also queried rpm for everything containing qt


rpm -qa | grep -i qt




qt-x11-4.7.4-2.fc15.x86_64
PyQt4-4.8.3-2.fc15.x86_64
poppler-qt-0.16.7-1.fc15.x86_64
qt-webkit-4.7.4-2.fc15.i686
qt-x11-4.7.4-2.fc15.i686
qt-4.7.4-2.fc15.x86_64
qt-4.7.4-2.fc15.i686



Hmm... so my system is x86_64. Do I need these i686 packages? Are these not being recognized by texmaker, perhaps? Should I be deleting these i686 packages (and their dependencies) and replacing them with the x86_64 versions?

See solution at the top. It's not worth my time to be wrestling with this level of hideous confusion.

It shouldn't matter that the 686 and x86_64 version of the libraries are installed. Anything that is compiled only for i686 will require those libraries. For a long time that included at least Skype, citrix client and second life. This would happen on any OS if you were trying to run 32 bit programs on a 64 bit OS.

That being said texmaker works perfectly fine for my system which means it can on yours.
tinypliny - 10/14/11 09:43
And, some of the earlier dependencies (eg. latex environment) were already installed in the laptop. Maybe that was the reason for the conflict. I have a sneaking suspicion this is not the end of the i686/x86_64 incompatibility drama. My brother seems to have installed whatever version was nearest his mouse. I will clean it up next month with you but right now I have no time.
tinypliny - 10/14/11 09:40
Okay, I bypassed luck by installed texstudio, a fork of texmaker. In this case, thank goodness, the linux community is torn by forks and strife.
paul - 10/14/11 01:59
You have the worst luck. I just ran sudo yum install texmaker and it worked. Sounds like you only have the 686 libraries installed and are running the x86_64 version of the app.

Good Song but I'm more a fan of the Metallica Version but that is just me...... That being said this would be perfect in a Movie I can Picture a Warrior looking over a valley before they have to run across trees or go to battle and slay the rival clan.....

Back on Fedora. Installing mp3/ape codecs.
Category: linux
My super-generous brother swapped out my crappy problematic System76 PanP7 this past weekend. As a result, I now have a brawny top-of-the-line quad core i7 8GB RAM Toshiba Satellite P750 with Dolby advanced audio and Harman/Kardon speakers. I have no idea why anyone would go through with this completely imbalanced swap but he did. It defies all logic. I guess I will always remain the little kid in the family who makes rotten decisions and constantly needs rescue.

And so I am back on Fedora 15 lovelock. Because that is my brother's preferred linux distro. Apparently he has now brute-forced F15 on the System76. I hope it works out for him. Since he has an internet connection that matches the century we live in (as opposed to the paleolithic lowly dial-up equivalent DSL that I have), the laptop didn't have any mp3 or ape codecs (because he streams all his media from the cloud).

Thankfully there is an easy way to make it old-world compatible.

In the terminal, type:

sudo c

rpm -ivh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm

rpm -ivh http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm

yum -y install gstreamer-plugins-bad gstreamer-plugins-ugly xine-lib-extras-nonfree gstreamer-ffmpeg
