This is the steps I followed to get Ubuntu 16.04 configured to start Java programming after it was installed. I am happy to say, that after taking the actions below I seem to have a pretty decent little machine.
I recently tried to use Ubuntu 18.04. After a lot of frustration I have moved back to 16.04. So much weird behavior. For example, none of my screen recorders work anymore (they just record black screens), it came with an installed version of Java that had some weirdness around the certicates, my file system become read only suddenly while I was working on some code, as I could not save, lost some work and finally it just shut down once and I was not able to boot back in (had to re-install). In summary, based on my experience, 18.04 has some issues. Stick with 16.04
At several points in this process I ended up in a place where, after a reboot, when I tried to log in it would accept my password but then not take me to the Desktop. Instead it would make a 'beep' like an error would happen and prompt for the password again.
For me to fix this I pressed Ctrl + F1 to get to the terminal. I then logged into the terminal and ran the following:
sudo apt-get purge nvidia*
sudo rebootThis got me back logging back in at least once. In another case I was not using Nvidia, so this did not work. I ended up redoing the install. This journey was not without its frustrations.
I had to deal with a loud CPU fan that seemed to never shut off (see below). One way to attempt to fix this is I flashed the Bios.
Here is where to get the latest BIOS: https://www.asus.com/support/Download/3/416/0/2/dFPFCR1MvzCTTcgs/8/
To figure out what version Bios you have, press F12 in the Bios. The version will appear in the lower right
Here are the steps I did to successfully Flash the Bios.
Here is document from ASUS outlining the steps: https://www.asus.com/support/faq/1008859
After the install, I was not able to Enable the Wifi card. This was fixed by running this command:
echo "options asus_nb_wmi wapf=1" | sudo tee /etc/modprobe.d/asus_nb_wmi.confSometimes after the laptop has been suspended, the wifi will not be able to connect to any networks.
The following command should fix the issue:
sudo systemctl restart network-manager.serviceSeems like the fan is always running on this laptop. Flashing the Bios really helped. Here are some other things I did.
I installed tlp:
http://linrunner.de/en/tlp/docs/tlp-linux-advanced-power-management.html
After installing it ran:
tlp start
sudo rebootI did have to enable insecure boot for this to work.
I did find some useful tools for diagnosis of fan noise and system state.
Here is a good way to see fan speeds and temperatures.
sudo apt install lm-sensors
luke@luke-K501UX:~$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +40.0°C (crit = +103.0°C)
coretemp-isa-0000
Adapter: ISA adapter
Physical id 0: +43.0°C (high = +100.0°C, crit = +100.0°C)
Core 0: +43.0°C (high = +100.0°C, crit = +100.0°C)
Core 1: +41.0°C (high = +100.0°C, crit = +100.0°C)
asus-isa-0000
Adapter: ISA adapter
cpu_fan: 4100 RPM
temp1: +40.0°C
To control fans, the following can be installed
sudo apt-get install fancontrolThe following Post explains how fancontrol can be used to put the fan on a more manual control and specify the ranges it operates. I have not gone this far at present, the Bios flash seemed to have helped as it now runs intermitently. However, should it start to run more frequently, I will be implementing this approach

If dealing with low freqeuncy (ie: 200 MHz !!!). A potential fix is, based Linux mylogin-K501UB 4.4.0-34-generic #53-Ubuntu x86_64 x86_64 x86_64 GNU/Linux:
Edit ""/etc/default/grub" file.
sudo vim /etc/default/grubChange GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="intel_pstate=disable quiet splash"
Then:
sudo update-grubAfter reboot change governor to performance
sudo sudo cpupower frequency-set -g performanceSpecific frequency may be set by:
cpupower frequency-set -d 2300000 -u 2300000Related link https://wiki.archlinux.org/index.php/CPU_frequency_scaling

At first I found the text fuzzy, so I installed Nvidia drivers and then tweaked the settings. But this resulted in getting looked out the desk top (see first note). For now I going to see if I can make do with it.
However, should someone wish to try the drivers:
sudo apt-get install gksuThen:
gksudo nvidia-settingsThis will pull up a UI to fine tune the Graphic Card setting. Note: To run this you will need to use the NVidia drivers (3rd party on Linux).
Here is a tutorial with more information on that: https://sites.google.com/site/easylinuxtipsproject/display
Ubuntu comes with a really stripped down version of Vi. Run the following to install something better.
sudo apt-get install vim-gnomeWhats cool is, if vi is typed in after running this command, its the full version. Not to mention the system now has Vim.
I work a fair amount with enterprises in Canada. To stay consistent with their environments I like to use the Oracle JDK. I downloaded it from here: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
Add a script (I usually call mine java.sh) like the following to /etc/profile.d
#!/bin/bash
export JAVA_HOME=/media/luke/data/tools/jdk1.8.0_91
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=$CLASSPATH:$JAVA_HOME/libSo STS is my fav IDE. And here is where to get it:
wget dist.springsource.com/release/STS/3.7.3.RELEASE/dist/e4.6/spring-tool-suite-3.7.3.RELEASE-e4.6-linux-gtk-x86_64.tar.gz

sudo apt-get update
sudo apt-get install git
sudo apt-get install mavenTo get git working properly I needed to execute:
git config --global --editThen remove the helper section, which included a reference to the osxkeychain. I think this happened when I followed Mac instructions accidentally. This is the correct was to cache the password in Linux:

Atom (the editor not the DC hero) is great for editing text with some awesome packages.
wget https://atom.io/download/debOn my Mac I love using Shiftit to position windows. It seems Compiz has a similar concept.
sudo apt-get install compizconfig-settings-manager compiz-plugins-extraHere is a little tutorial on how to use some of the features: http://www.howtogeek.com/167674/how-to-enable-and-tweak-ubuntus-flashy-graphical-effects/
To be able to watch DVD's you will need to add a few things:
sudo apt-get install libdvdread4
sudo apt-get install regionset
sudo regionsetAfter this DVDs should play on the machine using the Video player Ubuntu ships with or something like VLC. Handbrake will now also work.
Thats it for now. More details to come as I fine tune the system.
