AMD/Intel graphics switching from the BIOS

[Bucic]

Please help me out here, I'm loosing hope. No one has been able to help me with what seems to be a trivial issue.

Basic problem description:
Notebook with switchable graphics (old generation)
Catalyst driver installed for the AMD chip
Once the notebook is switched to use the AMD graphics and booted, switching back to Intel graphics brakes the graphics configuration (fallback mode etc.).

More details here (comprehensive description):

What exactly is the problem?

If you want to "remove" your graphics card you'll probably have to uninstall the proprietary drivers first.

[Bucic]

The problem is

my

system won't boot. Uninstalling catalyst driver every time I'd like to switch graphics (and then installing it again) isn't really an option. Especially that AMD legacy driver I use is not easy to install.

In any case - I provided detailed description of the problem (see the link!). If it's not enough, please specify the info needed.

To install the legacy driver just enable rpmfusion repository and

yum install kmod-catalyst-legacy

This is the driver and the method I *have to* use.

Also I tested it on a backed-up system yesterday - simply uninstalling catalyst and enabling Intel graphics brakes the system. It won't start past the fedora logo.

Bounty:
I offer 20 bucks for solving the problem.

Probably because when you install, it only takes the drivers for what it sees you have, I believe. I'm not sure.

I asked the same question on Phoronix http://phoronix.com/forums/showthrea...g-through-BIOS Since this topic has more views, lets continue here, unless you don't have fedoraforum account.

The bounty is up, $33 now.

Does this article answer your bounty?:

"The purpose of this script is to allow a user to select either the integrated or discrete graphics chip in the BIOS and boot into Linux and have it work without any configuration. This scripts allows the user to switch between integrated Intel graphics using the xorg driver and discrete ATI graphics using the fglrx driver. "

Also, at the bottom of the following page is a link to, "A small utility has been developed to switch between the chipsets with the ThinkVantage button, using Windows SetupAPI to detect the current chipset."

That does not answer your bounty because it does not require re-boot. But I thought you'd find it interesting.

[Bucic]

It looks like it does. Since the bloke on phoronix also provided his own solution the bounty will have to be split, but as 'yours' seems simpler the proportions would be vastly in your favor. I'll answer after I test it.

The poster on that Thinkwiki URL earned the bounty -- not me. I had the same question as you -- and found both your question and his answer in the same Google search.
