Broadcom wireless on Unbuntu

I got a lot of headache when I had to reconfigure the wireless of my wife's laptop after installing xubuntu. My wife's laptop is a Dell Vostro 1000 with a Broadcom card (BCM4311). This is a issue because it is not supported out of the box. After a lot of trial and error (a lot of) I found the way of getting it work. Here below the commands:

open a shell box and digit:

sudo apt-get update
sudo apt-get remove --purge bcmwl-kernel-source
sudo apt-get install linux-firmware-nonfree
sudo modprobe b43
sudo reboot
 
After these commands the pc should reboot and you should have your wireless up and running. Do not forget to check that the laptop hardware wireless is ON.

If it doesn't work... please do not shoot on the pianist!

Killing orphans and zombies

First please do not misunderstand me about "killing orphans and zombies". I'm for sure not going to hurt people without parents or people that are already dead :-( I'm talking about running processes that can be harmful for your system and shuld be better get killed. First of all a Zombie process is not an orphan process. As the word says, an orphan process is a procees without legitim parent, a zombie process is not alive but still have an entry in parent table. A process can be orphaned either intentionally or unintentionally. Sometime a parent process exits/terminates or crashes leaving the child process still running, and then they become orphans. In Linux/Unix like operating systems, as soon as parents of any process are dead, re-parenting occurs, automatically. Re-parenting processes whose parents are dead, means Orphaned processes, are immediately adopted by special process "init". Take a look to a htop situation where winexe causes a lot of or...

SOLVED: Can't establish a reliable connection to the server Google play store

Image
A couple of days ago I faced a nasty problem with my Android phone: It was not able to sign in the Google account / store. I thaught it was a temporary issue at Google's servers and I tried a couple of hours later, but nothing changed. I tried some usual things like clearing the cache of some apps, restart the phone and even change my Google account password and I resetted the phone twice to fabrics defaults. Nothing could help. I searched a lot of info on the internet and I found a hint about the hosts file. The hosts file is a computer file used by an operating system to map hostnames to IP addresses . I red that in some phones in the hosts file the adress to android.clients.google.com is translated to a certain IP address(es). Bang! what if Google changes the IP address for this domain? The first thing I needed to do was to root the phone and gain permissions to open the hosts file. I used Kingo ROOT which is a simple software to root the Android phones. After that, I ...

XPDF Segmentation fault (core dumped) SOLVED

I have a friend with a Linux Mint based on Ubuntu 13.04 that has to use a Java program (jnlp); this program has some print features that doesn't open a print dialog but fires XPDF directly. That's very annoying, because there is no possibility afaik to change the default pdf program inside the application. I suppose that the command is hard coded in the application itself. The problem is that XPDF opens and shuts down immediately and no pdf is shown. Launching XPDF from a terminal window the following errors are thrown: $ xpdf main.pdf ***** MediaBox = ll:0,0 ur:595.276,841.89 ***** CropBox = ll:0,0 ur:595.276,841.89 ***** Rotate = 0 Segmentation fault (core dumped) After a lot of trials without any success I found the solution to fix that: sudo apt-get install libfreetype6-dev libmotif-dev wget ftp://ftp.foolabs.com/pub/xpdf/xpdf-3.03.tar.gz tar xzpf xpdf-3.03.tar.gz cd xpdf-3.03 ./configure --with-freetype2-library=/usr/lib/i386-linux-gnu / --with-freetype2-include...
