Lenovo B560 With Atheros WiFi might have a issue with Ubuntu 11.04 - a work around for that

 After I got my new Lenovo B560 laptop I was thrilled and I was jumping in joy and being a Ubuntu buff I installed the latest and the greatest release from the grate Linux distributor Natty 11.04. Downloaded a iso file and using unetbootin created the bootable usb and use that boot in to my new Lenovo.
 As soon as I got in to the system what I noticed was that my wireless was not working so I kind a freaked and did a second download od the ISO and re-did every thing from the binging but with the same result. So with out no option I installed WiNDOWS and checked the wireless and bam it was working at that point I realized that theres some kind of a bug or a issue in the Ubuntu distro. So being a very long campaigner I knew that if there's a issue I could find a solution at the grate community. I asked my good friend Mr.Google who found me this answer and it worked like a charm for me thats why I'm posting this here hoping this will help any other one with the same issue.
There are two way of doing this first do the temporary one.

sudo rmmod -f acer-wmi
sudo rfkill unblock all
rfkill list all

After the above steps your wireless starts to work then make it permanent by doing this,

sudo gedit /etc/modprobe.d/blacklist.conf

Add the below line at the end of the file

blacklist acer-wmi

Proof read this before saving and if everything is ok then save it.
Now do this

sudo gedit /etc/rc.local

Just before the word end put this

rfkill unblock all

Proof read it twice if ok save it.
Now reboot your system, once you log in your wireless should work with out any problem 'cos this solved my issue.
Hope this helps and cheers.

A conflict between UBUFOX and ScribeFire

        This is my very first post after a very vaery long lay off. I mad some changes to my blogg the template and the name here thought the old one was bit too long and not that cachy. Any way I found some thng very funny today I'm using 2 Linux os in my desktop and in my netbook one is Ubuntu the other is LinuxMint (love this distro.) in both of them I use FireFox4(FF) as my deafault browser with my usual FF extentions.

        I may be not the biggest blogger in the world but I use ScribeFire because I just love it and very handy when it comes to quick post and it was rock solid in stability unlike most add-ons out there. But I started to face some issues with the newest releas of the FireFox family the version 4 ok intally this was little late to get upgraded with compatibility but after the fix was released I was faceing a very strange issue the funny thing was this issue was not to be found in my LinuxMint netbook along with the same FF version installed.

       Then I wanted some answers so I dialed my best friend Mr.Google but he was unable to say a ting to me so I enbarked to find the problem my self and tried everything I knew to find the issue. Nothing came up and I was getting frustrated when I saw the Ubuntu default extention that get installed auto matically with the system this is known as Ubuntu FireFox Modifications just to see what will happen I disabled this and boom ScribFire was functioning the way it should be.

         This extention was installed by two packages that get installed when we install the system,

          1. ubufox

          2. xul-ext-ubufox

You could keep the extention disabled or you can remove it by removing theres no harm do to the FF or to the usablitiy of the software. To remove the 2 packages clos FF and go to System -> Administration -> Synaptic Package Manager and search for thoes twa packages and mark them to be completly removed thats it no more issues with your favorit blogg editor.

 

Befor removing UBUFOX
