I recently bought a new HP DV6-3118SA laptop, but I am having a very discouraging problem with the graphics card. The graphics card is Radeon Mobility HD 5470. It doesn't install by default, but I do get some message suggesting to install the driver. If I install that driver, the next time I reboot, the screen goes blank and that's it! The same happens if I install the proprietary driver (fglrx) from ATI website.

Could you please help me with this?

EDIT: Following @Ronald and @Oli advice, I am dumping the output of lspci -k:

your wireless is probably missing a driver, but you should attach a report from hardinfo (available in software center) or lspci and split this into two questions (one for each device :). –  RolandiXor Mar 11 '11 at 18:21
    
To figure out the wireless, edit your post to show the output of lspci -k. It'll be a lot of data but somebody can trim it down to the relevant part once it's on here. –  Oli Mar 11 '11 at 18:22
    
Hi Promather i just bought the same laptop and facing exactly same issue!! wondering if you managed to solve this?? Appreciate any feedback Thank you –  user12318 Mar 13 '11 at 21:17
    
Unfortunately not. Mark suggestion below might be useful, but I am not ready to have to re-install (again) from the beginning. So I decided to leave it for the moment until I have some time to re-install if emergencies happen. Please let me know if you solve it. –  Rafid Mar 15 '11 at 7:52

I've had issues with ATI card drivers before and the following wiki always helped me;

http://wiki.cchtml.com/index.php/Main_Page

It will give you alot of info to install and troubleshoot the installation of ATI drivers.

I tried the instructions in that web page, but I also ran into the same problem (black screen). I might have done something wrong, but I am scared to try it again because it means I might have to re-install Ubuntu again. Any trusty why of installing the default driver (or maybe backing it up) so that I can return it in case of errors? –  Rafid Mar 12 '11 at 19:35
    
Promather - I found the following looking around on the Ubuntu Forum, its similar information to the ATI wiki but it may just help. ubuntuforums.org/showthread.php?t=1409467 –  Mark Rooney Mar 13 '11 at 11:11
    
Thanks a lot Mark. –  Rafid Mar 15 '11 at 7:51

I am no expert in this but this is certain - HP laptops do not give the BIOS option to select integrated or discrete GPU. Don't know about the very recent HP laptops. Now you have three solutions for now:

  1. Use Open source Radeon drivers (Great 2d acceleration / average 3d performance)
  2. Use only integrated GPU (Intel, power saver GPU, your battery will last longer)
  3. Flash your BIOS with modded ROM to lock the integrated GPU, hence you will be running with only discrete GPU (ATI). I do not recommend this. Do it at your own risk!

Well, after you installed the driver that ubuntu advises to install, reboot the pc, access to the bios and disable hybrid graphics ( selecting it to discrete). after that you should be able to see no more blank screen.
