Bug 216134 – app-laptop/macbook-backlight fails to find video card

• Product: Gentoo Linux
• Status: VERIFIED TEST-REQUEST

[Description no_return_address 2008-04-04 03:53:47 UTC]

As it currently exists, and when running on my MacBook, app-laptop/macbook-backlight complains that it cannot find the video card.

I was able to correct the problem by modifying this line in the source code:

#define PCI_ID_PRODUCT_GMA950 0x27A2

...and changing it to this...

#define PCI_ID_PRODUCT_GMA950 0x2A03

...and, to my complete surprise, that was all that was necessary.  I suppose it needs to just look for either value, but changing a simple constant is about the extent of my coding skills.

Reproducible: Always

Steps to Reproduce:
1. Read description.
2. Reproduce steps mentioned there.
3. I don't know...

Must be fix in the release 0.2.
Can you confirm ?

[Comment 4 no_return_address 2008-04-06 05:16:29 UTC]

Yes, that fixes it.  Thanks!
