Ubuntu Over Heat On Dual Switchable Graphic Card Laptops

After a long time of non-ubuntu I decided to try the 13.10 to see if I am still sharp, first thing I notice is my laptop "Pavilion DV6" getting really hot, to be exact 96 Celsius while the fan is spinning non stop like crazy, CPU usage, was really low, but guess what's the problem.
My laptop have 2 graphic cards, intel and ATI, one for power saving, one for gaming, in Ubuntu they run both at the same time, making it crazy hot, and I am sure it can burn your laptop if you live in a warm country, now don't panic, as long as it's not on fire you still can turn off one of them, I choose to turn off the ATI, I like power saving plus I wont be gaming on Ubuntu anyway, just not my kind of gaming platform, why? open source games are crap, what ? no? well jump down if you wanna fix your over heating problem and forget about my open-source gaming problem.

First open up your terminal and type in the following command

/sys/kernel/debug/vgaswitcheroo/switch

You will get an output like this
0:DIS: :Pwr:0000:01:00.0 <- This is the discreet VGA or the ATI, and it's turned ON, you can tell by the word Pwr
1:IGD:+:Pwr:0000:00:02.0 <- This is the Integrated Intel Graphic card, and it's also on, trouble?

Now to permently disable the ATI card and get back your sanity, and save your legs from burning of course, fire up Gedit using the following command.

Sudo gedit /etc/rc.local

and add the following line right before the exit 0

Overall file should look like
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

echo OFF > /sys/kernel/debug/vgaswitcheroo/switch

exit 0
Save, reboot and, Enjoy.

If you would like to switch off the integrated graphic card just instead of OFF write IGD
Now by testing using the command /sys/kernel/debug/vgaswitcheroo/switch you should see that only one of them got the PWR  ON ;)

Tria Mera - 666 - The truth

Following is a reference to the movie white noise, what you see on this page is not my opinion, and I am not interested on this stuff, if you come here than you are probably searching after watching the movie or researching tria mera term, this is for educational purposes only.



The expression, Third Day, appears in several narratives in the Bible. (Occasionally, it is “three days.”) Some biblical interpreters have thought that some of these third day motifs have significance by signifying a certain divine principle, and a few interpreters have thought that they are cryptic in meaning. Why? Interestingly, these narratives record some of the most important events in the history of Israel. And surprisingly, except for the Bible’s mention of the third day, the seventh day, and its account of creation in Genesis 1, the Bible rarely mentions the other days of the week.
The Number of the Beast is described in the Book of Revelation 13:18. From the King James translation:[5]

Hacking With Google, Spy Cams

This is a quick post since I have to sleep and feel so tired ...
by searching for one of these strings on google :
inurl:ViewerFrame?Mode="
inurl:MUltiCameraFrame:?Mode="
inurl:view/index.shtml"
inurl:axis-cgi/mjpg"
inurl:ViewerFrame?Mode="
inurl:MultiCameraFrame:?Mode="
You will be able to view other people webcams, not everyone, but everyone that have a cam can be viewed on any browser by writing the ip address with the pc connected to it, and indexed by Google since you can access that on port 80 or 8080 ...
