Screen brightness is not controllable/screen is off or backlight is 0 after resume I have tried suspend with a stripped down GENERIC (usb, wifi, ethernet, sound etc drivers all removed). This did not affect the outcome, the laptop resumes fine, but the screen is off. The is a noisy ACPI error about setting some PCIE stuff into D2...? (Oct 3 16:51:45 sylph kernel: pci0: failed to set ACPI power state D2 on \_SB_.PCI0.EXP7: AE_BAD_PARAMETER) I have investigated acpi_video...I can't seem to get it to do anything on this machine, although all the ACPI handles it looks for are present. sysctl hw.acpi.video.lcd0.active=1 does (0 => 0), and brightness changes have no effect. xset dpms force off && sleep 2 && xset dpms force on actually does work, the only thing which does. dpms.ko does not work. xbacklight finds no screens. acpi_ibm does attach with LEN0068 added as an ID, but setting brightness suddenly causes correct fan speed, around 1950rpm to become 65535 rpm...I think this might be close to the fix. The acpidump (I have posted it here:https://docs.google.com/leaf?id=0B6YlMzJxarGbYjE4OTgzYjYtOTQ1OC00YWU3LWE0MGItZDk1MmZiMDIxNTRh&hl=en_US) actually checks for FreeBSD during OSI. Doesn't seem to help. I can't seem to make either acpi_ibm or acpi_video adjust the backlight although both seem to think they can. Ultimately, I think if we can set backlight, we can fix the screen after resume...I think it's just the backlight is low/off on resume... 2. psm does not detect synaptics click pad To make matters worse, xf86-input-synaptics doesn't like it either. I have seen some linux posts where the device probe for PS/2 was disrupting it (psm?) and xf86-input-synaptics says "found mouse model 0 instead" This of course is simply annoying and not as annoying as broken screens! There are other small things that may I have not cared to test such as fingerprint reader and camera card reader. Matt
