I have retested using the latest thinkpad-acpi-0.18-20071203 release; sorry for not doing that at the outset. This version avoids creating the /sys/class/backlight/thinkpad_screen device. However, the other glitches I originally reported remain: - two devices in /sys/class/backlight for one piece of hardware - acpi_video0 appears to do nothing useful at all - acpi_video1 works well, except that levels 0-19 are no-ops Are these real thinkpad_acpi bugs, or things I should accept as permanent and try to work around in user space using HAL's quirk management features? ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
