How to install my display card driver? Previously, I did the following things:
- Downloaded the official driver from AMD.com : http://support.amd.com/en-us/download/desktop/legacy?product=Legacy2&os=Linux%20x86_64
- Now I have this :

- Did this in a terminal :
chmod +x amd-driver-installer-catalyst-13.1-legacy-linux-x86.x86_64.run - Did this in the terminal :
sh amd-driver-installer-catalyst-13.1-legacy-linux-x86.x86_64.run
- I got this windows, chose the first option and then click "continue" :

And this windwos :

.log file : http://paste.ubuntu.com/7320170/
Now what can I do?
Thank you for your attention
