Bug Description
On my Dell inspiron 9300 laptop under intrepid (hardy did not have this problem), when I type FN + Arrow keys to change the screen brightness, Most of mouse and keyboard keys stop working.
For an example : I can't type any text anywhere, ALT + F4 does not close any window, mouse clicks "partially" opens the gnome-panel menus, isn't able to close windows with the right-top x, but mouse click is still able to move a window..
screencast : http://
This bug is reproducible under both metacity and compiz, and not caused by a BIOS password.
A quick workaround to bring back things to normal is to switch to a VT and go back to Xorg with CTRL + ALT + F6 and CTRL + ALT + F7
When changing screen brightness, I get this in Xorg.0.log :
(II) AIGLX: Suspending AIGLX clients for VT switch
(II) Open ACPI successful (/var/run/
(II) AIGLX: Resuming AIGLX clients after VT switch
(II) AlpsPS/2 ALPS GlidePoint: x-axis range 0 - 1023
(II) AlpsPS/2 ALPS GlidePoint: y-axis range 0 - 767
(--) AlpsPS/2 ALPS GlidePoint touchpad found
(II) Macintosh mouse button emulation: Device reopened after 10 attempts.
(**) Macintosh mouse button emulation: YAxisMapping: buttons 4 and 5
(**) Macintosh mouse button emulation: EmulateWheelButton: 4, EmulateWheelIne
(II) PS/2 Mouse: Device reopened after 10 attempts.
(**) PS/2 Mouse: YAxisMapping: buttons 4 and 5

I'd like to add that my laptop often takes around 2 minutes to shutdown because it waits a very long time for acpid. Might be related to the same problem.
