this is my first question at here, so please be gentle if do something wrong.
I have Ubuntu 14.04.03 LTS installed on my laptop. Also i have working dual boot to Windows 10 with UEFI activated.
My laptop is warming up too much faster than Windows, tempature never downs below 65 C.
I search this problem a bit and i see posts about bumblebee Nvidia drivers etc. So i decide to install proper Nvidia drivers to use Nvidia GTX960m only when i choose.
For that i had to install Nvidia drivers first, but when i tried and reboot i cant pass the login screen. When i check xsession-erros file, i see some erros like that;
Xlib: extension "GLX" missing on display ":0.0".
I had to remove all nvidia packages to correct this situation and login again. What am i doing wrong?
Also i'm open advices for any other choices. I just use Ubuntu for developing at Ruby; so i dont need to use Nvidia GTX960m really. I just want to keep my laptop cool ( make as much as ) and last longer at battery.
Thanks!
Ps: English is not my native language, if i spelled something wrong; i'm sorry.

The below answer is only applicable if your laptop has nvidia Optimus:
I got my optimus laptop working with bumblebee/nvidia. Temperature is ~48C idle
Basically you do this:
install bumblebee and the nvidia driver
then you need to sudo gedit /etc/modules and add
then you need to sudo gedit /etc/modprobe.d/bumblebee.conf and make sure the line
is there, if not add it.
finally you need to sudo gedit /etc/bumblebee/bumblebee.conf
line 22: >Driver=nvidia
line 55: >KernelDriver=nvidia-352
line 58: >LibraryPath=/usr/lib/nvidia-352:/usr/lib32/nvidia-352
line 61: >XorgModulePath=/usr/lib/nvidia-352/xorg,/usr/lib/xorg/modules
reboot.
This answer comes from: http://rajat-osgyan.blogspot.gr/2015/05/how-to-install-latest-nvidia-driver-in.html
see there for more explanation. It is approved by many (and me)to work, though the difference is that i don't use ppa:xorg-edgers (since it is unstable) and use ppa:mamarley/nvidia and ppa:bumblebee/stable, i recommend you do that instead.
Games run "almost" fine and i can use my both my cards simultaneously.
intel core i5-3210m, GT 650M
P.S what do you mean by "proper" nvidia drivers?
