One Stop solution for adjust screen brightness in Linux


This one is just temp/quick fix for brightness issue for Linux machines. Some people, like me cannot stand with higher values of computer screen brightness. We surely adjust as per our eye suitability.  But what if we work on Office Machines or using a friend’s one ? May not all the time, we shall have full permission to change the screen brightness. In such cases, this quick fix can be a heaven for your eyes. 😛

First

we find which display device we are connected to. open your Terminal and fire this below command. Please dont type ‘#’ also. It is for just to indicate that is a terminal / shell env.
#xrandr -q | grep ” connected”

Now, this will output the connected display such as

VGA1 connected primary 1366×768+0+0 (normal left inverted right x axis y axis) 344mm x 194mm 

This is in my case, but it will vary as per systems. For me VGA1 is my display. Some times it may show LVDS1 and so on.

Now, use the second command for set up our brightness level

#xrandr –output VGA1 –brightness 0.6

that is, we set the brightness 60% of maximum brightness. This is ok for my eyes, but not for my Boss, so whenever he leans to my monitor for some thing, I will set this back to 1. voila !

So thats how Save Eye from Blindness going !! 😛

Korora 21 – A powerful riding horse


Korora21 – A tamed Wild Horse
———————————–
Korora is some thing a well trained powerful horse with all setup for the ranger  as in Fedora, the user has to take the extra effort / time.

I was a satisfied K20 user, which is the first time I got my hand laid over Korora.  I had some small issues with PulseAudio permission issues wit k20 but apart from that the experience was awesome.

so, K21 does keep that awesome impression. I chose XFCE spin, XFCE is getting better and mature, it is the new Gnone Classic.  The installation went pretty smooth and tidy. The new system logged me in very fast, faster than my other two distros (Frugalware and NetRunner 15).

Some of the points that make this Distro cooler

1. System responsiveness is strong and stable. Not bloating, lagging
2. Memory consumption is nominal
3. Excellent Theme and Icons (GreyBird)
4. I can install and Fedy for tweaking and customization
5. Fedora repositories with extra, like an Ocean, one can install any thing they need

SMPLAYER was not in the default applications. But it took just a minute to install with  yum. Same as Skype, I installed with Fedy.

Yumex is the GUI for package management, which is still Raw and Basic compared to the Debian / Arch equivalents. Hope Fedora will bring some thing cooler and easier.

So, at the end of the day, Korora 21 is just awesome distro for your general purpose computing. You can be a noon, inter or advanced. This distro surely deserves higher ranking in Distrowatch 🙂
