Hello freebsd-acpi@, I have lenovo ThinkPad Edge E145 laptop and the LCD brightness control stopped working somewhere between 10.2-RELEASE and 10.2-RELEASE-p6. I used to adjust the brightness using Fn-=E2=98=BC- and Fn-=E2=98=BC+ butto= ns and it always worked (during boot, in X, text console). Now, it works only in the loader, before the system boots. I tried alternative methods listed below, but non had any effect. Please help! ;) Thank you in advance, Stefan ** acpi_call acpi_call -v -p '\VBRU' Path: \VBRU Number of arguments: 0 ioctl: Device not configured no effect ** acpi_ibm sysctl dev.acpi_ibm.0.lcd_brightness=3D7 values change, but no effect ** acpi_video sysctl hw.acpi.video.lcd0.brightness=3D50 hw.acpi.video.lcd0.brightness: 50 -> # no effect pressing Fn+(sun)+- buttons has no effect, but logs: can't evaluate \134_SB_.PCI0.VGA_.LCD_._BQC - AE_NOT_FOUND
