I have installed ubuntu on my laptop, HP. Processor i3, and has ATI Thames Xt[Radeon HD7670M] graphics card.
I have installed the Catalyst driver with the help of what-is-the-correct-way-to-install-ati-catalyst-video-drivers-fglrx
Even after installing the graphics driver, laptop is over heating.
I tried to to modify the following files, /sys/module/pcie_aspm/parameter/policy
/etc/default/grub as mentioned in notebook overheating
But i'm not able to modify these files, I tried changing the file permission using chmod, but that is also not working
I already so many question related to this issue.
Thanks in advance..
