Small tool to adjust screen brightness on nVidia cards that supports SmartDimmer. Tested both with nVIDIA Geforce Go 6200 (on a Sony Vaio VGN-S480 laptop) and with nVIDIA Geforce Go 7200 (on a Sony Vaio VGN-SZ38GP laptop.)

Created attachment 138612 [details] Smartdimmer ebuild with amd64 keyword It is the same ebuild at the top, with amd64 keyword. I am testing it on my amd64 gentoo
Created attachment 138618 [details] Smartdimmer ebuild with amd64 keyword - script corrections Now it has generalized path.
(In reply to comment #8) > Created an attachment (id=138618) [edit] > Smartdimmer ebuild with amd64 keyword - script corrections > > Now it has generalized path. > Thanks Antonio! Latest ebuild for amd64 is worked on x86 & amd64 machines. I've check it on nVIDIA Geforce Go 7400. Guys, is already possible to include this ebuild to main portage tree?
(this is an automated message based on filtering criteria that matched this bug) 'EBUILD' is in the KEYWORDS which should mean that there is a ebuild attached to this bug. This bug is assigned to maintainer-wanted which means that it is not in the main tree. Heuristics show that no Gentoo developer has commented on your ebuild. Hello, The Gentoo Team would like to firstly thank you for your ebuild submission. We also apologize for not being able to accommodate you in a timely manner. There are simply too many new packages. Allow me to use this opportunity to introduce you to Gentoo Sunrise. The sunrise overlay[1] is a overlay for Gentoo which we allow trusted users to commit to and all users can have ebuilds reviewed by Gentoo devs for entry into the overlay. So, the sunrise team is suggesting that you look into this and submit your ebuild to the overlay where even *you* can commit to. =) Because this is a mass message, we are also asking you to be patient with us. We anticipate a large number of requests in a short time. Thanks, On behalf of the Gentoo Sunrise Team, Jeremy.
