I have installed ubuntu 10.04 LTS, 64 bit, on a HP Probook 4530s with AMD 6490M video card. However, the display is running in a strange resolution, and on gnome-display-properties the monitor says "Unknown".

lspci

When running a 32 bit live CD with ubuntu 11.04, it detects it as AMD 6470 instead of 6490 (but runs it in fine resolution and the effects run ok). As far as I can understand, here it is detected as 6760 (or it may be detecting the Intel VGA, I'm not sure). Please help

Funny thing, after issuing

update-pciids

The new lspci also shows the videocard as
$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: ATI Technologies Inc NI Seymour [AMD Radeon HD 6470M]

but still doesn't detect it on gnome-display-properties.
