.Dd February 20, 2011 .Dt FUJBP 4 .Os .Sh NAME .Nm fujbp , .Nm fujhk .Nd Fujitsu Brightness, Pointer, and Hotkeys .Sh SYNOPSIS .Cd "fujbp* at acpi?" .Cd "fujhk* at acpi?" .Sh DESCRIPTION Some Fujitsu laptops come with vendor-specific .Tn ACPI devices to manage the laptop hotkeys (such as the .Sq Eco button), and to control various built-in components (such as the display, the touchpad, and the speakers). The .Nm and c fujhk drivers provide support, through these .Tn ACPI devices, for hotkeys, backlight on/off switch, brightness level control, and pointer on/off switch.
p The following .Xr sysctl 8 read/write variables are provided (when hardware support is available): l -tag -width hw.acpi.fujbp0.brightness -offset indent t Va hw.acpi.fujbp0.brightness Brightness level (integer). t Va hw.acpi.fujbp0.pointer Pointer switch state (boolean). t Va hw.acpi.fujhk0.backlight Backlight switch state (boolean). .El
p Please note, however, that future versions of the drivers may remove these .Xr sysctl 8 variables without prior notice. .Sh SEE ALSO .Xr acpi 4 , .Xr acpivga 4 , .Xr sysctl 8 , .Xr pmf 9 , .Xr sysmon_pswitch 9 .Sh HISTORY The .Nm and c fujhk drivers appeared in .Nx 6.0 . .Sh AUTHORS .An Gr\('egoire Sutre .Aq gsutre@NetBSD.org .Sh CAVEATS Brightness level and backlight switch state should be controlled via .Xr wsconsctl 8 instead of .Xr sysctl 8 .
p The .Xr sysctl 8 variable .Va hw.acpi.fujbp0.pointer should be replaced by a platform-independent userland control.
