------- Comment #7 from [EMAIL PROTECTED] 2008-01-22 01:01 ------- Hi, Henrique, >1. video.c is "fixed" to do rounding to the nearest _BCL-provided level patch is in a 2.6.23-rc8. >2.tell video.c to NOT export a backlight interface ... I think we should export the backlight control I/F to user space, export the brightness change notifications to user space via input layer. then we can stop the acpi video driver action upon hotkey press. that's what X want so that X can handle the backlight stuff all by itself. >since it does more (such as video output selection), video output selection? I don't think users can do this via the backlight sysfs I/F. But I think the ACPI video I/F for video output switch (/sys/class/video_output/...) should be removed as these ACPI control methods for display switching seldom works. >3. We fix the issue video.c has with inactive ACPI nodes that it is exporting interfaces for. I think this is with the high priority. Thomas and Mattehw already got the proposal for this. >1. talk to the kernel >2. talk directly to the hardware >3. talk to ACPI(?) or maybe to both. I asked a Graphics guy and he said that xbacklight can be be configured to: 1. NATIVE mode, poking the registers 2. LEGACY mode, write the PCI config space. 3. COMBO mode, try both 1 and 2. 4. KERNAL mode, poking the /sys/class/backlight/..., even may looking for /sys/class/backlight/thinkpad_acpi/... -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
