I've installed Jaunty and I want to report the brightness behaviour there; I hope I didn't need to open a new bug report.

* I again blacklisted the video module because of the same problem (each key changing the brightness twice).

* With the default /usr/share/hal/fdi/information/10freedesktop/10-laptop-panel-hardware.fdi file, laptop_brightness_in_hardware was not defined, and I assume it defaults to false, because the brightness adjustment window had a "software brightness level" of its own, and when I changed the brightness too rapidly the software level was different than the hardware level and there were glitches.

* I overwritten 10-laptop-panel-hardware.fdi with the new version Martin uploaded here; now I have laptop_panel.brightness_in_hardware = true and this saved me from the previous glitches while rapidly changing the brightness.
Now the problem is that the brightness adjustment window always thinks the level is zero; it can't read the hardware brightness level.
Nevertheless, `cat /sys/devices/platform/acer-wmi/backlight/acer-wmi/actual_brightness` does allow me to see the correct brightness level, so the kernel knows about it.

Any help with the last problem?
