But I noticed a small problem: I tried echo 15 > /sys/class/backlight/thinkpad_screen/brightness which generated EINVAL, as expected. But afterwards all values generated EINVAL, even reasonable ones such as 0 through 7. EINVAL was also generated when trying to set the value through procfs, either by up/down or level N. Prior to trying 15, the 0-7 values didn't signal EINVAL errors. The kern.log is filled with messages like Oct 3 00:21:50 ravna kernel: set_level status: 0 which originate in "drivers/acpi/video.c". My interpretation is that some variable in ACPI got set to a bad value and is now stuck there. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
