Thank you for your response! 

(a) I am using the following kernel (3.14.2)

uname -a output:

Linux localhost.localdomain 3.14.2-200.fc20.x86_64 #1 SMP Mon Apr 28 14:40:57
UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

(b) Although I had installed bumblebee, it is not running. Optirun said that
bumblebee service is not running. I have removed bumblebee now.

(c) How do I check that runtime pm and vga switcheroo are enabled in my kernel.
(Sorry, but I am a newbie to Linux).

(d) I cannot be sure about this as well. AFAIK, the nouveau module is built
into the kernel. The modinfo result is as below:

Actually I am working on some OpenGL/GLSL projects, for which I need GLSL 4.3,
which I believe is still not available in nouveau driver. I was looking forward
to be able to install the latest NVIDIA drivers. Will mesa 10,2-rcl solve this
issue? Can you please recommend any other solution.

Thank you for your time and effort. For future reference, I will use wiki/bugs.
