I assume they just act as a keypress? (And I'm guessing that the nv driver hooks into that somehow... although the only reference to 10f0 that I see is in turning the thing on/off, perhaps it just leaves something untouched that nouveau touches and messes up.) This should be fairly easy to implement... You know what register to control, what the min/max are. I'm guessing it's just 10f0 that matters -- the other register controls whether the CRTC is on/off. It should be easy to stick something into nouveau_backlight.c that deals with your sitation. Instead of keying off of card family, you'd key off of dev->pci_device, like dfp.c:nv04_dfp_update_backlight does. You should give it a shot if you're interested.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
