Public bug reported: 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://upload.leservicetechnique.com/bugs/mouse_keyboard_acpid.ogv 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/acpid.socket) (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.
