This bug needs to reopen for ubuntu 10.10 amd64, installed by upgrading 10.04. I can confirm this happens all the time on HP 550 Notebook. Running gnome-power-manager in verbose mode shows
TI:23:38:21 TH:0x247b0a0 FI:gpm-backlight.c FN:gpm_backlight_brightness_evaluate_and_set,357 - Key 232 mapped to key brightness-down - emitting button-pressed : brightness-down - Button press event type=brightness-down - Button press event type=brightness-down So, when ever ac power is reconnected it triggers brightness-down. Reproducible always. There no other info I can find, that can be related to this. Any help would be appreciated.
