Worst luck indeed: Fedora 15 BSOD
Category: linux

Seriously? Behold Fedora 15's Black Screen of Death.

Looks like I might need a hard reboot. The wretched thing is not coming out of this error screen. And it goes into it at every boot and suspend.

Apparently, this is a known new bug:

With some insights from here:

ds,
Your issue is related to the optimus technology deployed in the m14x, it's a new piece of tech that allows switching between your nvidia card and intel sandy bridge. In short, your nvidia card does not work on Linux out-of-the-box. Read more about how you can either disable your nvidia card (I did that and saved 14 w (1Â½ hours of battery time) or try and enable it using some experimental tech called switcheroo. Read more here:

My brother's hacky solution:

Close the lid for 15-30 seconds and then open. If it doesn't work, repeat as many times as necessary.

I can only say... !!!

Yes, there is a sandy bridge. The laptop has onboard intel graphics AND discrete nvidia graphics card with a kind of hybrid switching technology. The problem is this kind of switching is not supported in linux so it throws errors like the one above.

Now I have no way to adjust resolution or brightness. There is no way for me to adjust/turn it off in BIOS. I checked.

uncutsaniflush - 10/16/11 18:37
The usual way to turn graphic cards on and off is in the bios.

My assumption that the nvidia card is an add-on (probably pci express) and the laptop came with a main board with sandy bridge bridge providing onboard graphics. But as always, I could be wrong.

tinypliny - 10/16/11 16:50
The error has gone away after a fresh install of F15 with xfce. But I need to figure out how to turn the NVIDIA card off if it turns up again in the future. Both the solutions from here: :::link::: acpi_call and byo-switcheroo don't work for Toshiba P750. I need to touch base with (e:Paul) about this sometime this week and post an update.

Plagued by this once more. I am seriously doomed.

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.

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.....

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.

paul - 10/14/11 11:03
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.
