I have (in a laptop) 000:02:0: Intel Sandy Bridge (mobile) GT2 Integrated Graphics Device (VGA display, revision 0x09) 001:00:0: ATI Technologies Radeon HD 6400M (VGA display) I think the first one is not used. According to your suggestion, the only relevant items in the whole `sysctl -a' seem to be: hw.acpi.acpiout1.brightness = 100 hw.acpi.acpiout2.brightness = 100 hw.acpi.acpiout6.brightness = 100 hw.drm2.i915.invert_brightness = 0 hw.drm2.radeon_backlight = -1 If I try (as root) to change the values of any of them, the operation is permitted, but it has no effect (hw.acpi.acpiout* still remains at their value 100), or it is not permitted: sysctl: hw.drm2.i915.invert_brightness: Operation not permitted sysctl: hw.drm2.radeon_backlight: Operation not permitted In fact, I am not able to modify the brightness of my screen: if I press the F2-F3 keys which should do this, nothing changes. This is just FYI, as another example of hardware. Maybe the NetBSD driver still doesn't offer a full flexibility with some configurations like this one. Bye! Rocky
