I ran the codesudo lshw -c display to get the model of my graphics card that I am using. It showed Whistler 6600M series along with my Intel HD Graphics. I have switchable graphics. But my graphics card is HD 6750M. Why would it be shown differently and how to rectify this?

Output of lspci -nnk | grepVGA -A1:

00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0116] (rev 09) Subsystem: Hewlett-Packard Company Device [103c:1646]

01:00.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI Whistler [AMD Radeon HD 6600M Series] [1002:6741] (rev ff) Kernel driver in use: radeon

The devices are named after what they are in the PCI ID database. Look at the database entry for this device.

On 2013-03-16 it was updated from Whistler [AMD Radeon HD 6600M Series] to Whistler [Radeon HD 6600M/6700M Series] and there have been a ton of updates since.

On my computer it shows Whistler [Radeon HD 6600M/6700M/7600M Series].


Why is this? Well if you look at your /usr/share/hwdata/pci.ids file, you'll see when it was last updated. Why is yours old? Because you're using an older version of Ubuntu, probably. I doubt they'd backport an insignificant package like hwdata. Here's my version for your reference.

$ apt-cache policy hwdata
hwdata:
  Installed: 0.234-1
  Candidate: 0.234-1
  Version table:
 *** 0.234-1 0
        500 http://archive.ubuntu.com/ubuntu/ raring/main amd64 Packages
        100 /var/lib/dpkg/status

What I should really underline is this doesn't matter even a tiny little bit. Hardware lookups should only be being done on the ID (the [1002:6741]) so there's really nothing to worry about. It's just calling it the wrong name.

For me it shows installed: 0.233-1. So it must be an old one. Actually I asked this question because I thought this was the reason why I have got black screen repeated times trying to install catalyst center according to ubuntuforums.org/showthread.php?t=1930450.

BTW How would I update this "hwdata"? –  Colorless Photon Aug 23 '13 at 14:45
    
I don't think a simple upgrade is provided for 12.04. You could nab the version from 12.10 or 13.04 from Launchpad (see Binary Packages on the right) but frankly, it would just update your database. It won't fix anything. –  Oli Aug 23 '13 at 14:56
