I re-built acpi_ibm and I now have the acpi_ibm sysctls, but most don't seem to do anything. dev.acpi_ibm.0.%desc: IBM ThinkPad ACPI Extras dev.acpi_ibm.0.%driver: acpi_ibm dev.acpi_ibm.0.%location: handle=3D\_SB_.PCI0.LPC_.EC__.HKEY dev.acpi_ibm.0.%pnpinfo: _HID=3DLEN0068 _UID=3D0 dev.acpi_ibm.0.%parent: acpi0 dev.acpi_ibm.0.initialmask: 2060 dev.acpi_ibm.0.availmask: 134217727 dev.acpi_ibm.0.events: 0 dev.acpi_ibm.0.eventmask: 2060 dev.acpi_ibm.0.hotkey: 2484 dev.acpi_ibm.0.lcd_brightness: <--Does not work dev.acpi_ibm.0.volume: 0 <--Does not work dev.acpi_ibm.0.mute: 0 <--works dev.acpi_ibm.0.thinklight: 0 <--works dev.acpi_ibm.0.bluetooth: 0 <--N/A dev.acpi_ibm.0.wlan: 1 <--Works (Read-only) dev.acpi_ibm.0.fan_speed: 2629 <--Works dev.acpi_ibm.0.fan_level: 0 <--Does not work dev.acpi_ibm.0.fan: 1 <-- Don't know Since the volume and brightness buttons don't work, I have to be careful to leave them at max or I won't have full volume available and the LCD will be dim. I do see LCDBrightness referenced in the DSDT, but I see nothing on either the fans or volume. I'm on a T520 running 9-Stable amd64. Any idea of getting brightness and volume to work? I also have the problem of no video after a resume. Other then that, it sus= pends and resumes just fine. I need to confirm whether the display is really blan= k or just needs the backlight turned on. --=20 R. Kevin Oberman, Network Engineer - Retired E-mail: kob6558@gmail.com
