How to install ATI Radeon Graphic drivers on Ubuntu 14.04? [duplicate]

Question

This question already has an answer here:

• What is the correct way to install proprietary ATI Catalyst Video Drivers (fglrx) directly from AMD? 5 answers

I have recently updates my 5 yrs old HP dv5 AMD laptop to Ubuntu 14.04, all good so far just that I am not able to grasp the right process to install drivers for the ATI Radeon card provided in this laptop.

Though I am happy with the current graphics on the monitor just that I am not able to change the resolution setting, default I am getting below options:

"1280 x 800" and below, nothing over it.

I am new to Ubuntu/Linux so how should I install the correct drivers to allow me to get the correct resolution?

Answer 1

You can follow the official Ubuntu how-to guide.

In short - open your terminal and type:

sudo apt-get install fglrx

Then generate a fresh xorg.conf, before you reboot:

sudo amdconfig --initial

Reboot. It is a good idea to read the whole article that I have linked to you. There you can find examples how you can backup you current settings and restore them if something fails.

Answer 2

Open System Settings. Click on Software & Updates. Click on the additional drivers tab. You should then be able to select another graphics card driver and click Apply Changes.
