ASUS N53S and Ubuntu: USB 3.0 and Nvidia graphic card not working

Well I am having ASUS N53S on which I have installed Ubuntu. I have noticed an issue with USB 3.0 and on bard Nvidia Card. whenever I connect anything with USB 3.0 and I am not able to see anything. As far as Nvidia card is concerned I am having GeForce GT 550M. I have noticed that 3d Destiny not able to see nVidia card. as I look for updating the Nvidia drivers then it is showing nVidia driver is being used. But still I am not getting an option to activate it.

Whenever you are supposed to install proprietary nvidia driver from repos through additional drivers it creates blacklist file but it should be added into blacklist.conf so that it will keep loading of nouveau.
You should launch the terminal and run following commnabd

Code:

---

sudo nautilus

---

enter password when prompted.
Browse for etc/modprobe.d and you have to double click on blacklist.conf and you have to add following lines

Code:

---

blacklist nouveau
blacklist lbm-nouveau
blacklist nvidia-173
blacklist nvidia-96

---

In this particular situation I would recommend bumblebee ppa. Since it will allow you to use both onboard video and discrete based on application in use.

As it is mentioned in the previous post to make use of bumblebee to use the Nvidia graphic card.
You have to run below mentioned command on the terminal.

Code:

---

git clone https://github.com/MrMEEE/bumblebee
cd bumblebee
sudo sh install.sh

---

if you have not managed to get 3d acceleration on intel GMA after restarting and you will need to optionally install latest version of X.org-drivers.

Code:

---

sudo add-apt-reposity ppa:xorg-edgers/ppa
sudo apt-get update
sudo apt-get upgrade
sudo ironhide-configuration

---

To make working USB 3.0 on your system you will need to add following line at the grub boot parameters

Code:

---

pci=nomsi

sudo nano /etc/default/grub

---

you have to replace

Code:

---

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

---

With

Code:

---

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nomsi"
 And save  update the grub

sudo update-grub
