Hello, as of 2.6.37-rc kernels, backlight is dimmed to level 2 as soon as I close LID. After opening, backlight level is not restored to my level (4). However, /sys/class/backlight/acpi_video0/brightness still reports level 4 even if real level is 2. I have Lenovo ThinkPad T61 with 965GM. -- Lukáš Hejtmánek
