The only remaining barrier to entry for Linux

If asked, what would you think is the biggest challenge facing Linux mass adoption? Jack Wallen takes on this question with an answer you might not expect.

After my last piece, "Alternative is the question; Linux is the answer," I received quite a lot of feedback. Much of that feedback was positive. Some, as you might expect, went the opposite direction. Those who sent in the negative feedback promised to re-answer the question for me.

Their answer? To my shock and dismay, went something like this:

The answer is Windows. Why? Because Linux is too hard to install.

Pardon me while I double take, spitting soda out of my mouth and through my nose.

My response to the backlash is to wonder if those crying out against Linux have even bothered to attempt an install of a recent release?

Sure, I'll give them this... back in the day, Linux was not easy to install. In fact, there are still a select few distributions that seem to not quite understand the need for an easy-to-use GUI installer. But those tend to fall into the fringes. The mainstream Linux distributions offer an installation process that is as simple as it gets.

In fact, I decided to do a comparison between installing Ubuntu Linux 15.04 and Windows 10.

How To Save Screen Brightness
In Ubuntu 14.04 LTS
(Solution For Screen Brightness Problem On Ubuntu 14.04)

Laptop users still have the screen brightness problem with Ubuntu 14.04.Every time the screen brightness gets maximum value on Ubuntu startup.

we can solve this problem by adding a small startup script to adjust the screen brightness levels on ubuntu startup.The script will automatically set/overwrite the default brightness value with specified/desired brightness value when Ubuntu boots up.

Here the step by step guide to save the screen brightness on Ubuntu 14.04 :

step 1 :

open Terminal by Ctrl+Alt+T

step 2:

Navigate to backlight directory.

cd /sys/class/backlight

step 3 :

Now you can see two directories(acpi_video0 and radeon_bl0) inside the backlight directory.
To see them use ls command.

ls

step 4 :

The upcomig steps depends on your computer processor . So you need find whether your computer is powered by intel or AMD.
The following command will show your processor name....

lscpu |grep -i vendor

sample output for AMD :

shivaraj@shivaraj-A14RM0E:~$ lscpu |grep -i vendor Vendor ID: AuthenticAMD shivaraj@shivaraj-A14RM0E:~$

sample output for Intel :

shivaraj@shivaraj-Latitude-D630:~$ lscpu |grep -i vendor Vendor ID: GenuineIntel shivaraj@shivaraj-Latitude-D630:~$

step 5 :

Change your screen brightness level to which you want to set as default.
Now find the equivalent value for current brightness level by using this command

If your processor is AMD then follow this step....

cat /sys/class/backlight/acpi_video0/actual_brightness

The above command will give brightness value.

Sample output:

shivaraj@shivaraj-A14RM0E:~$ cat /sys/class/backlight/acpi_video0/actual_brightness 2 shivaraj@shivaraj-A14RM0E:~$

If your processor is Intel then follow this step....

cat /sys/class/backlight/intel_backlight/actual_brightness

if the above command didn't show any variations in brightness value for different brightness values..
then, in above command, replace intel_backlight with the name of another folder(see:the output of step 3) present inside the backlight folder. and try again..

Sample output:

shivaraj@shivaraj-Latitude-D630:~$ cat /sys/class/backlight/dell_backlight/actual_brightness 2 shivaraj@shivaraj-Latitude-D630:~$

[NOTE: Remember This Brightness Values For Future Usage]

step 6 :

Get root privileges by using this command:

sudo -i

step 7 :

Now we need to create a new configuration file called fixbrightness.conf

gedit /etc/init/fixbrightness.conf

step 8 :

Now Paste the following code into the above created (fixbrightness.conf) file.

description "Sets brightness after graphics device is loaded"
start on graphics-device-added
task
exec /bin/echo 2 > /sys/class/backlight/acpi_video0/brightness

In above code,Replace the value 2 > with the brightness value we found in step 5
Similarly, Replace the folder name acpi_video0 with the folder name you used in step 5(before the word actual_brightness in code)

step 9 :

Thats It... Now Reboot Your System

sudo reboot
