I can confirm it on Hardy, running kernel 2.6.24-19-generic on Inspiron 1520.
I found that the problem is kernel related: When pressing Fn+Up/Down once, `cat /proc/apci/event' gives every event twice. (Catting /proc/apci/event is possible only after killing acpid.) Monitoring key presses with xev or showkey is of no use. I inspected acpid source code and it works like this: - acpi event is generated by kernel - acpid reads /proc/acpi/event and for every event read it runs a script (e.g. /etc/acpi/video_brightnessup.sh) - this scripts runs acpi_fakekey with some argument that passes a synthetic key press to the X server - X, KDE or Gnome (whatever takes the responsibility) runs an action bound to the key press So, if the event is generated twice by kernel for one Fn+Up/Down key press, KDE's or Gnome's action is run twice. What more information can I provide? ** Attachment added: "dmidecode.txt" http://launchpadlibrarian.net/19170812/dmidecode.txt -- brightness changes twice when using hotkeys https://bugs.launchpad.net/bugs/257827 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
