this intel installer make the battery drain as fast as the nvidia driver!!!
before installation working with intel driver let the computer stands more than 5 hours, but now only it stands for 2hours 30min with the same conditions.
Black screen after switching to the nvidia driver using nvidia-prime, removing xserver and reinstalling it solve the problem, but unfortunately, the battery still draining so fast and trying to switch to nvidia driver make an error.
Im using an Asus N56VB with an Intel and Nvidia 740M graphic card, and running Ubuntu 14.04LTS
may any one help us to uninstall this driver and revert to the default drivers
Of course. Assuming you are on Ubuntu (as we didn't release an updated driver on the Fedora side):
dpkg -l i915\*
You should see a package with a name like 'i915-3.16-3.13-dkms'
apt-get remove <package> that package and you will have returned to the vanilla i915 driver.
You will need to reboot for the old driver to be loaded again.
Hm - that is worrying - to help us solve this problem for other users, would you be willing to give us:
• The output of "lspci -vvnn"
• The exact make and model of your laptop?
I'm so sorry, I really wanted to help but, as I've got no response here, and as I was in rush, I decided to go with a fresh Ubuntu installation. Looks very weird!!! here's why : Before reinstalling Ubuntu, I tried to switch to Nvidia driver but a message error appears. After that, the system shows many errors at the startup and the unity won't start. Dropping to the prompt shell using the recovery mode, I purged Nvidia packages and I reinstalled xservers. This leads to a black screen. Trying many long fixes dealing with this problem leads to fed me up and let me decide to backup my home dir and run a fresh installation.
Ah, that's too bad.
Just for our future reference, so someone can look into possible problems
with the hardware you have, could you tell us the make and model of your laptop, and ideally the
lspci -vvnn output as well? Might help us prevent someone else from seeing these problems.
