well. the problem is quite clear.
when pressing hotkey, Linux kernel video driver tries to control the backlight.
while some userspace scripts listen to the acpid and try to set the backlight
as well.
the first solution is that "echo 0 > /sys/.../brightness_switch_enabled", which
can prevent the ACPI video driver from changing the backlight.
An alternative is to remove the user space scripts in /etc/acpi/events/.
I think you can easily figure out which script brings the flicker.
Reject it as this is not a kernel bug.
Pechnikov,
please re-open it if you still have any questions. :)
