Maybe at -rc3 or thereabouts. For now, it is only for the git-initiated :) Please don't use -rc1, but rather linus' latest. It is *much* safer to always use the latest when tracking -rc, and to upgrade often (once a day or so). > In 2.6.25-rc1, I had some success with brightness control: > > - using "native" interface in xrandr (so I may not get the maximum > brightness but as "kernel" doesn't work...) > - using a powersaved script to catch LCD acpi events and run (as the X user) > xbacklight > - having 0 in /sys/module/video/parameters/brightness_switch_enabled so I > only have LCD acpi events and not IBM/hotkey (and thus I have less delay > between typing the key and having the actual brightness change) > > What will 2.6.24.2 plus thinkpad-acpi 0.19 20080213 improves on this? It will be the same, but you won't have to load video.c to get the LCD ACPI events. That said, please test the thinkpad-acpi backlight device to check if it is still working, and that it still gives you 16 brightness levels. If you could post the thinkpad-acpi debug output to me (compile with thinkpad-acpi debug mode enabled, and load it with the debug=0xffff parameter), it would be helpful as well. Just the output when you modprobe it is enough. Thanks. -- "One disk to rule them all, One disk to find them. One disk to bring them all and in the darkness grind them.
