Fglrx on laptop with A8-4500M, Radeon HD7640G + HD7670M hybrid graphic

Good afternoon!

I have a laptop with the graphics cards mentioned in the subject line. Do you guys and gals know if they will work with Arch and if they do, will it require anything extra apart from the driver installation?

I've heard some people had a hard time getting hybrid graphics to work under linux and thought I'd ask about your opinions and experience before trying it out myself.

Thanks in advance.

I personally have had a miserable time trying to get my setup to work (Intel HD4000 and ATI Radeon 7850M), but my ATI card is not really compatible with the open-source "radeon" driver and the "fglrx" driver is a pain to work with.  You may want to try The Hybrid Graphics Post on ArchWiki, since it looks like your cards are supported.

Let me know how it goes.

I have dual ATI cards. Open source has inferior power management for my dual cards, even when using vga_switcheroo. Having great experience with fglrx both battery-life wise and performance wise.

radeon
Battery: 2:30 hrs
Performance: ran well, but choppy when playing Minecraft.

fglrx
Battery: 4:30 hrs
Performance: working well all round, plays Minecraft without choppyness. Probably due to boasted improved 3d performance.

Some people have said that radeon with "low" power management mode gives them more battery life than fglrx however, so I'd try both and swap if you think you are unhappy with the results of the open source driver.
