Ubuntu 14.04 Tweaks

Here are some of the Ubuntu 14.04 tweaks I’ve found and took note of.  I didn’t invent or figure out any of these things (so don’t give me credit).  I just googled and then used them and took note of them so that I could use them in the future.  I no longer know where I found any of these so I’m sorry I’m not linking to the real source.  Hopefully someone else will find these useful too.

Click icon in unity taskbar minimizes a window or restores a window:

To enable:
dconf write /org/compiz/profiles/unity/plugins/unityshell/launcher-minimize-window true

To disable:
dconf write /org/compiz/profiles/unity/plugins/unityshell/launcher-minimize-window false

Change the terminal tab color so it is easier to see which tab is selected:

# Add this to the file to change the tab color in terminals so you can see which one is selected.  This will make the ative tab white and the inactive tabs grey

# Modify this file
/home/username/.config/gtk-3.0/gtk.css

TerminalWindow .notebook tab:active {
background-color: #ffffff;
}
TerminalWindow .notebook tab {
background-color: #C0C0C0;
}

Add ‘open in terminal’ to nautilus file browser:

sudo apt-get install nautilus-open-terminal

Force a higher resolution than the laptop screen provides:

Enable higher resolution:
xrandr –output LVDS1 –panning 1640×922 –scale 1.2×1.2

This is how I can force resolution to go back to default:
xrandr –output LVDS1 –panning 1366×768 –scale 1×1

Install encfs so you can have encrypted directories:

# Install encfs
sudo apt-get install encfs
sudo addgroup <your username> fuse

# Install Gnome Encfs Manager
sudo add-apt-repository ppa:gencfsm
sudo apt-get update
sudo apt-get install gnome-encfs-manager

Encrypted Folders with Ubuntu 14.04 LTS (32bit)

Yesterday I setup encrypted folders using Ubuntu 14.04 LTS (32bit).  First I used CryptKeeper and then I switched to Gnome Encfs Manager.

I wanted an encrypted directory that could hold some old documents that needed to be encrypted (pdf statements, spreadsheets, etc).  First I installed encfs like this:

sudo apt-get install encfs
sudo addgroup <your username> fuse

Then I installed CryptKeeper from the Ubuntu Software Center.  CryptKeepr was sketchy.  Sometimes the toolbar shortcut was there.  Sometimes it wasn’t.

Then I tried Gnome Encfs Manager.  To install it I did this:

sudo add-apt-repository ppa:gencfsm
sudo apt-get update
sudo apt-get install gnome-encfs-manager

Gnome encfs manager has more options and seems to just work.  It will mount your encrypted directory wherever you like (configurable).  When you try to mount it it asks your for a password.  You type it in and tada!  Encrypted dir!

Brother MFC J825DW with Ubuntu 12.04, Windows 7, RHEL 6.4 and Android 2.3

I recently bought a Brother MFC J825DW all-in-one printer/scanner/copier/fax machine. This is a wifi enabled printer so it made it possible for me to put the printer downstairs in the same room where we keep the kids’ computers. Now I don’t have to hear the loud printing noises in the middle of my work day. My wife is in school so she prints a lot – hundreds of pages of coursework for her classes. I was sick of leaving the room while I was on the phone to avoid the loud printer noises. Now the printer is downstairs closer to her and I am no longer tethered to the printer.

Here are my end of week one observations:

  • Setup for wireless use was super easy and did NOT require tethering it to a computer
  • Setup for Google Cloudprint was easy so I can print from my Android devices
  • Ink is cheaper than my old HP and there are generic suppliers that make Ink VERY cheap.  I’m not sure they work yet but I’m hoping they do.
  • Setup on Ubuntu was easy
  • Setup on RHEL was easy
  • Setup on Windows was easy
  • Print quality is just OK when on draft mode.  Draft mode and fast printing is fast and faded because it uses less ink.  I’m OK with the draft quality but I wish it was just a tad bit better.  Nothing to complain about though.
  • The printer doesn’t have any lights to tell you it is on – but it is on.  A tiny led would have been nice – but I don’t mind now that I know it is on even when not lit up.
  • The printer is more quiet than my old HP.  I could hear the old HP from downstairs.  This printer I cannot hear from upstairs.  Sometimes I can barely hear it from the next room.
  • So far I’m VERY happy with it

Ubuntu 12.04 Fix Screen Brightness For Lenovo G580 Laptop

I’m posting this to help anyone that has the same problem I did.  The problem was that my Lenovo G580 screen stayed at max brightness after installing Ubuntu 12.04 LTS (32bit).  The brightness up / down buttons did nothing.  During the day it wasn’t much of a problem but in the evening the screen was too bright.  The fix was pretty simple:

Edit the grub file:
sudo vi /etc/default/grub

Change this line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

So that it says:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"

Save and exit the file.

Now update grub:
sudo update-grub

Ubuntu 12.04 All Around

I recently switched to Ubuntu 12.04 for three of my computers (my lenovo g580, my son’s hp desktop and my other son’s dell laptop).  I had a very hard time making the switch because I ran into troubles with 13.04 not working for wifi on my Lenovo g580 or the 12.10 nvidia drivers not working on my son’s HP Pavilion a1540n desktop.  Then I accidentally installed a 32bit version of 12.04 that I had on CD.  I thought it was a 64bit version but it was a 32bit version.  It worked like a charm all around.  It solved my nvidia problems on the desktop and my wifi problems on my g580 laptop as well.  So nice.  Now I run RHEL 6.4 on my work laptop and Ubuntu 12.04 on my personal laptop, my son’s HP desktop and my other son’s Dell laptop.  My wife’s netbook is the only one left in the house running Windows (Windows 7) – Yay!
