Hi, I wanted to ask if there was any progress on the understanding of the situation?
I have a Thinkpad T61 (8897 with intel G965), running Linux 2.6.25 (vanilla+thinkpad-acpi 0.19-20080321, but I can test with debian 2.6.25) and xserver-xorg-video-intel 2.3.0-1 (experimental). Brightness keys sure don't work out of the box (nor in console nor in Xorg). acpid, powersaved and hald are running. I can stop them for testing if needed. The driver by default uses the BACKLIGHT_CONTROL "kernel". xbacklight works fine. I have a /sys/class/backlight/acpi_video0 and 1. acpi_video0 does nothing, but using acpi_video1 and echo'ing 0-15 to brightness works. But in that case, xbacklight is lost. xbacklight =100 # brightness is at full level cat /sys/class/backlight/acpi_video1/actual_brightness 15 # acpi_video1 agree echo 0 > /sys/class/backlight/acpi_video1/brightness # brightness is at minimum level (but is not off, while it has worked at one # time) cat /sys/class/backlight/acpi_video1/actual_brightness 0 # acpi_video1 agree xbacklight 100 # xbacklight disagree. That's even without trying brightness keys. Pressing brightness keys generates here acpi events video LCD0 87/86 (with some delay, but I guess this one is a kernel problem). Nobody seems to catch it, nor hal, nor powersaved, nor X driver. I don't know what's the role of everybody involved, from the enduser pov, something is wrong. If you need more information, please ask, I'd be glad to provide stuff. Cheers, -- Yves-Alexis -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
