Hi Experts,

I'm trying install ubuntu 12.04 on my dell 7520 (http://www.dell.com/content/products/productdetails.aspx/inspiron-15r-se-7520?c=us&l=en) but i'm experience very issues.

1º I can not install the drivers of my AMD 7730M correctly, I already try the last catalyst for ubuntu and this http://askubuntu.com/questions/192381/how-to-turn-off-ati-radeon-hd-7730m-on-dell-inspiron-7520?answertab=active#tab-top , but still no luck.

2º  The next issue is the fan is quite noisy even when the ntb is almost Idle. (max 10% CPU usage). Can you recommend me some software which could do this power management to minimize the noise? I have tried CPU frequency scaling indicator, but it seems that it has not any effects. I already try the jupiterapplet but still very noisy and hot.

Best regards

Hi, does your machine have the latest BIOS installed?

See this for reference: http://askubuntu.com/questions/190335/dell-inspiron7520-and-ubuntu-12-04-issues

Did you try another Linux distribution or does it have to be Ubuntu?
You could try Fedora or Mint for example.

i8kutils/i8kfan/i8kmon/i8kctl can manage and monitor your fan(s).

The latest catalyst driver should do the trick. However, I also had video problems in my Dell laptop in Ubuntu, but after switching to Fedora several months ago, video works great.
