--- Comment #6 from Henry Hu <henry.hu...@gmail.com> --- (In reply to Adrian Chadd from comment #5) > Absolutely! > > http://people.freebsd.org/~adrian/laptop/lenovo_x230/ > > > -a Have you tried acpi_call -p "\_SB.PCI0.VID.LCD0._BCM" -i <brightness> And what's the value of acpi_call -p "\VIGD" acpi_call -p "\_SB.PCI0.VID.DRDY" VBRC() calls SMI directly. I have no idea what it is doing inside SMI. _SB.PCI0.VID.LCD0._BCM stores brightness in BRLV and calls _SB.PCI0.LPC.EC.BRNS() and UCMS(0x16). UCMS() calls SMI directly so I have no idea what it is doing. If _SB.PCI0.VID.DRDY is true, it calls _SB.PCI0.VID.AINT(). AINT() triggers an ASLE interrupt to set the brightness through the driver. I'm not sure what went wrong here. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-bugs@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
