turn off backlight for nv driver on Dell D800
Comment 1 FreeDesktop Bugzilla Database Corruption Fix User 2005-06-05 13:06:53 UTC
The nv driver doesn't seem to turn off the backlight on my Dell Inspiron 8600
either (running Fedora Core 3 and x.org 6.8.2-1)
Comment 2 R. Steven Rainwater 2005-12-13 09:07:48 UTC
Backlight also fails to turn off on the Dell Inspiron 8600
Comment 3 Erik Andren 2006-06-28 12:04:38 UTC
Any plan on merging this one or should the bug be closed?
Comment 4 Giuseppe Bilotta 2007-01-05 15:25:53 UTC
Backlight doesn't go off on Dell Inspiron 8200 either with an nVidia GeForce2 
Go. I can however switch to a console and issue the command 'vbetool dpms off' 
which does turn off the backlight(and then blind-type 'vbetool dpms on' to turn 
it back on)

Sorry about the phenomenal bug spam, guys.  Adding xorg-team@ to the QA contact so bugs don't get lost in future.
Comment 6 Giuseppe Bilotta 2008-01-05 03:59:40 UTC
I have a patch that can be used to turn off the backlight on a Dell Inspiron 8200, submitted to the xorg mailing list: http://lists.freedesktop.org/archives/xorg/2007-September/028672.html

Aaron was waiting for feedback from the hardware guys, but it's been 3 months since. Any news?
Comment 7 Aaron Plattner 2008-02-05 12:08:09 UTC
Giuseppe, I submitted your patch on the 25th.  It's in xf86-video-nv-2.1.7.


Egbert, the patch attached to that XFree86 bug has the same system-specific limitations that Giuseppe's does.  I'd be open to having some sort of subvendor/subdevice quirks database, but definitely can't accept applying the patch to all GeForce4 4200 Gos.  Reassigning to reporter and setting NEEDINFO to get the PCI subvendor and subdevice IDs.
