Hello all,

I have laptop for 2 years and I try to use my ATI cards, I tried to search on google and fedoraforums, also other distro forums too. All of I want use ATI Graphic Card, I'm use my Intel Ironlake Graphics, but sometime I need to use ATI because I was installed Maya(By Autodesk) and this software recommend to using ATI or Nvidia,

What am I have to do ? How can I switch my graphics cards ? .

Thank you.

You would need to write 2 xorg.conf, one for your intel card and one for your ati card.

You would then swap out xorg.cof and re-start X

How much or little of that ^^ do you know how to do ?

You can try with vgaswitcheroo for having switchable graphics. Get some insight from below question asked here regarding vgaswitcheroo

If you don't have it, then probably your setup is not supported by vga_switcheroo.

Does your intel card use an xorg.conf ? When running with your intel card, what is in /etc/X11/xorg.conf ?

If not, it makes it easy, you can write an xorg.conf with aticongfig (assuming you have the ati catalyst driver installed from rpmfusion).

you then move the ati xorg.conf in and out of place and re-start X

Well, we need to start with a working configuration for BOTH you your ATI and Intel card. See : https://wiki.archlinux.org/index.php/Xorg You do not need an entire xorg.conf, what you do need is a Device section where you specify a driver for your card(s).
