These are just some quick notes on the various Java programs that I install. I’m sorry the notes are not very complete. I’ll do better next time, but I thought these notes might still have some value.

Backup Experiments
In following up with my encryption experiments, I wanted to use the same virtual machine to do some backup experiments. Here’s the basic thought: I want to use the Redo Backup & Recovery CD to make an image of my virtual machine. Then, I want restore that image on a brand new virtual machine.
It’s pretty straight forward. Here are my notes…
Experiments with Encrypted Disks on Ubuntu
Because of some increased security demands, I decided that I need to explore and understand encrypted home directories. First, I want to see it work where I can’t see the information from a Live CD. Second, I want to make sure that I can still get to the information in case I have to rescue it from a Live CD.
So, here’s my experimentation…
Ubuntu 13.04: Finally Fixing my Touchpad
On my Ubuntu 13.04 installation, I have had trouble getting the touchpad to work. The driver just wouldn’t install. I finally figured it out.
Amazon Prime Fix Again
We have enjoyed watching many of the Amazon Prime videos in the past. Unfortunately, on the last few machines that I have rebuilt, they wouldn’t play. It just said to upgrade the Flash Player. The usual tricks didn’t work.
Update: I found a different but easier solution for Ubuntu 13.10. See this post.
Thanks to Ask Ubuntu and Aaron, I found the solution. In summary, here are the commands that got the job done:
sudo apt-get install hal sudo mkdir /etc/hal/fdi/preprobe sudo mkdir /etc/hal/fdi/information /usr/sbin/hald --daemon=yes --verbose=yes rm -rf ~/.adobe
Here are the steps…
Ubuntu 13.04 Networking
As I setup my laptop with Ubuntu 13.04, I did several things to configure my networking needs. This article attempts to document my setup.

Ubuntu 13.04 and the Fight for the Mouse
The mouse is something that should just work. Is it a bad sign when your mouse won’t work at all? You can see my problems with UNetbootIn on my previous post.
Even after I got it installed correctly, I still had trouble with all of my mouse input types. I still haven’t figured out how to get the Touchpad features working (like multi-touch) or the USB to reliably work. If you have any ideas, please comment.
Touchpad
The touchpad works as far as normal mouse features. The pointer moves and the right and left clicks work. The problem is that it isn’t recognized as a touchpad. Therefore, the scrolling and multi-touch features work. In the mouse settings, you’ll notice that all of the touchpad features are gone.
I tried a couple of quick searches, and I didn’t find anything new. So, I just followed the same instructions that I used on 12.10. I used this download link. Then, I extracted and installed with…
sudo tar -xf ~/Downloads/psmouse-alps-dst-0.4.tar -C /usr/src/ sudo bash /usr/src/psmouse-alps-dst-0.4/install.sh
Unfortunately, the build failed with this message in the middle of it:
cleaning build area.... make KERNELRELEASE=3.8.0-22-generic -C /lib/modules/3.8.0-22-generic/build M=/var/lib/dkms/psmouse/alps-dst-0.4/build/src psmouse.ko....(bad exit status: 2) Traceback (most recent call last): File "/usr/share/apport/package-hooks/dkms_packages.py", line 22, in <module> import apport ImportError: No module named apport Error! Bad return status for module build on kernel: 3.8.0-22-generic (x86_64) Consult /var/lib/dkms/psmouse/alps-dst-0.4/build/make.log for more information. Build failed
I tried installing the linux-source package. That didn’t fix the error at all, so I tried installing the python-apport package. That one fixed one of the errors, but it still didn’t completely compile.
Next, I found the driver on Git Hub: psmouse-alps. I downloaded the zip file from the front page, and I extracted it to the /usr/src directory:
sudo unzip psmouse-alps-master.zip -d /usr/src/ cd /usr/src/psmouse-alps-master/ sudo dkms add . sudo modprobe -r psmouse sudo dkms build -m psmouse -v custom-1.2 --all sudo dkms autoinstall --force sudo modprobe psmouse
I got closer, but the autoinstall wouldn’t work. It couldn’t find the directory. So, I took the install script from the other directory and updated it to this:
DLKM=alps-master KERN=$(uname -r) echo "MAIN: Driver source files by Dave Turvene. Install script by garyF." echo "MAIN: Install script updated by Stephen Phillips." echo "MAIN: Removing previous versions of psmouse-alps-dst..." sudo dkms remove psmouse/$DLKM --all echo "MAIN: Building current driver from source files..." sudo dkms build psmouse/$DLKM if [[ $? == 0 ]]; then echo "MAIN: Installing the driver" sudo dkms install psmouse/$DLKM sudo rmmod -v psmouse sudo modprobe -v psmouse echo "MAIN: Done installing. Go to System Settings > Mouse and Touchpad to configure :-)" else printf "Build failed\n" cat /var/lib/dkms/psmouse/$DLKM/build/make.log fi
I found this error message:
/usr/src/linux-headers-3.8.0-22-generic/arch/x86/Makefile:103: CONFIG_X86_X32 enabled but no binutils support
Update: I finally fixed it.
Bluetooth Mouse
My first attempt didn’t work on my bluetooth mouse. My second attempt ended up working with no problem.
I went to the bluetooth icon by the clock and clicked Bluetooth settings. I made sure that it was on. I don’t think that the visible was necessary, but I turned it on just in case. Then, I hit the bluetooth button on the bottom of my mouse. The power light flash green and red to show it was broadcasting.
On the settings dialog, I hit the plus sign to add a device.
The first time I tried, it wouldn’t find any devices. I gave up. Several updates and reboots later, I tried again, and this time, my mouse was in the list:
I selected the device and clicked Continue. It was that simple:
USB Mouse
In previous versions, my USB mouse had stopped working. I did some research and found a few bugs, but I never found a solution. This time it worked at first, but after a minute or two, it just stopped working. It seems to be hit or miss for some reason.
Here’s the dmesg output:

I’ll have to research this more later.
Ubuntu 13.04 A Ruckus with Ringtail
This past weekend, I finally got the time to go through installing Ubuntu 13.04 (Raring Ringtail). Here’s to documenting it…
I have been trying to rebuild my laptop with each new version of Ubuntu. This is proving a little more challenging, but this is my first post. This is as much of a story as my other posts, and if you have any suggestions please comment.
Preparing the Installation Media
The troubles started at the outset for me. The default tool for putting an iso on a USB drive had been crashing, so I have dropped back to UNetbootIn. I had mentioned that on several posts, and this one is no different.
It worked fine at first, but after I went through the install, my wireless wasn’t recognized. Then, I found that my USB ports weren’t working; at least, I couldn’t mount a USB key or external drive. Also, my touchpad wouldn’t work.
I did a little searching around, and I found Husain’s Chronicle. He mentioned that the problem seems to be common with everyone who used UNetbootIn. It seems very strange to me because the problem happens not when you boot off the USB but after booting to an installation made by the USB drive. Still, I went to my other computer that happened to be running Linux Mint, and I used the “USB Image Writer” program:
The only thing that I noticed different was the boot loader was different. The install went exactly the same, but when I booted, I had no trouble with the touchpad, the wireless, or the USB drives.
Partitioning
I tried the option to remove the Ubuntu 12.10 partitions and reinstall, but that didn’t work for me. I have special preferences on where I want my partitions. Yes, I have to be difficult.
I have a solid state drive (apparently /dev/sdb) that I want to use as my root. My thought is that I want all of the binaries and the swap partition on the faster solid state drive. Then, I have a 1TB drive (/dev/sda) that I want to use for my home folder where I will place all of my files, pictures, virtual machines, etc.
I set the large partition to format and to mount on the /home folder:
Next, I removed all of the partitions on my SSD drive and created an 8G swap partition at the end:
Finally, I created my root partition with the rest of the space:
Encrypting the Drive
This time I decided to encrypt my home folder to add a little security. This is my first try at this, so I’ll have to see how things work. So far, it doesn’t seem like any complication for the security that it adds.
On the first boot, it prompted me to save my key.
So, I ran ecryptfs-unwrap-passphrase. Note that it says, but I missed it the first time: when it asks for the “Passphrase”, it is asking for the password that you associate with your user account, the one when you login to your computer.
Cleaning Up the Launchers
One of the first issues that I notice is that the launcher on the left is full of icons that I don’t necessarily use all of the time. So, I removed most of them to make room for running applications:
Adding Google Software
Google offers a software repository. Rather than just trying to install chrome by downloading the deb, I installed the repository with:
wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add - sudo sh -c 'echo "deb http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list' sudo apt-get update sudo apt-get install google-chrome-beta
I had expected chrome to show up in the Ubuntu Software Center, but it never did. It worked fine to install from the command-line though.
Shutter
Shutter is one of the first things that I install so that I can document and blog my install. It is an easy install from the Software Center:
For configuration, I don’t like the way the program sticks the screenshots in the Pictures folder. To me, that is for photos rather than screenshots. So, I create my own screenshots folder:
Then, under Edit > Preferences, I set it to use the new folder:
On previous versions, I had to tweak the settings to get it to show by the clock. This install, I didn’t have to do anything, and it shows up!
Since I am always taking screenshots of things, I set it to start automatically. I checked the first two options on the “Behavior” tab:
Restoring Backups
I copied off all of my important content off to an external USB drive. I installed grsync to make copying easier. Then, I copied the following directories back:
- ~/Documents: This is where I put all my document files
- ~/Pictures: I have Shotwell pointed at this directory, so it contains all the pictures from my cell phone and digital camera
- ~/MIS: I keep my work files in a different directory
- ~/app: This has all of my programming stuff (“application development”)
- ~/VirtualBox VMs: These are the virtual computers
- ~/.config/google-chrome: The settings for Chrome (extensions, bookmarks, etc)
- ~/.gnome2/keyrings: My saved passwords
- ~/.Skype: Skype history
- ~/.remmina: The settings for my remote connections
- ~/.ssh: The keys for my remote ssh connectinos
- ~.local/share/shotwell: The settings and thumbnails for my photos (moved from ~/.shotwell, see Ask Ubuntu)
- ~/.sword: The downloaded Bible files for Xiphos (and the underlying Sword library)
- ~/.VirtualBox: The settings for my virtual machines
- ~/.filezilla: The settings for my FTP connections
- ~/.sqldeveloper: The connection settings for SQL developer
- /etc/NetworkManager/system-connections and /etc/NetworkManager/VPN: this saves all of my wireless connections and VPN connections
Other Utilities
I like to use the “Main Menu” program, or alacarte to update the list of applications for the Applications Dash.
Bumblebee for the Discrete Video Card
WebUpd8 has a great article for installing Bumblebee. I decided to try the Bumblebee Configurator GUI. Notice that the program name changed from gtk to gui — bumblebee-config-gui.
sudo add-apt-repository ppa:alessandrofac93/bumblebee-config-gtk-dev sudo apt-get update sudo apt-get install bumblebee-config-gui
Issue … I started it with “sudo bumblebee-config”. All I got was this output:
Traceback (most recent call last): File "/usr/bin/bumblebee-config", line 17, in <module> wnd = BumblebeeMainWindow() File "/usr/lib/python2.7/dist-packages/bumblebee_config/bumblebee_main_window.py", line 53, in __init__ if self.aptHelper.checkBumblebeeInstalled(): File "/usr/lib/python2.7/dist-packages/bumblebee_config/apt_helper.py", line 112, in checkBumblebeeInstalled if cache['bumblebee'].isInstalled: File "/usr/lib/python2.7/dist-packages/apt/cache.py", line 204, in __getitem__ raise KeyError('The cache has no package named %r' % key) KeyError: "The cache has no package named 'bumblebee'"
There is a bug opened for this issue. Just as a guess, I tried to add the repositories:
sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo add-apt-repository ppa:bumblebee/stable sudo apt-get update
After that, it worked fine:
I found that I needed to click on the “Configure Bumblebee” button first to choose the Nvidia driver:
I clicked the “Install Bumblebee” button, and it started installing…
When I ran check status, I got this message:
Bumblebeed status: [ 7161.740177] [INFO]Configured driver: nvidia [ 7161.742547] [INFO]Switching method 'bbswitch' is available and will be used. [ 7161.744668] [ERROR]Module 'nvidia-current' is not found.
Everything still seemed to work fine, though. The nvidia-current package was actually installed. I don’t know why it reports that “not found” message.
Time to Clean Up: Out of Space for New Kernels
This past update, I started getting a new error. My /boot mount was full. The problem was that I had 6 or 7 previous kernels still in the mount taking up space.
I was able to fix it with a command written by Linerd. He did a very nice job explaining it, so I would recommend that you follow through and read his post.
To make a long story short, I first ran the trial command:
dpkg -l linux-* | awk '/^ii/{ print $2}' | grep -v -e `uname -r | cut -f1,2 -d"-"` | grep -e [0-9] | xargs sudo apt-get --dry-run remove
Then, I ran the full command (without the –dry-run):
dpkg -l linux-* | awk '/^ii/{ print $2}' | grep -v -e `uname -r | cut -f1,2 -d"-"` | grep -e [0-9] | xargs sudo apt-get -y purge
Now, I am good to go! Thanks Linerd.

Fixing the Scrollbars
I ran across this article that mentioned removing the scrollbars on windows: Ubuntu 12.10 Quantal Quetzal Post Installation Guide. These scrollbars have annoyed me for a while. If you use a scroll wheel on your mouse, they’re great. They use less screen space. But, if you actually have to click on them, they elusive.
