Description Hans de Goede 2010-02-10 04:54:47 EST
Hi,

The udev keymap for micro star devices makes the kernel send brigthness up / down
events for 2 special msi scancodes. But these scancodes are not emitted on keypress, but when the brightness is actually changed (through an acpi call, done
by linux).

This causes the back-light brigthness to oscillate very fast, leading to an unusable flickering display.

This upstream patch fixes this:
http://git.kernel.org/?p=linux/hotplug/udev.git;a=commitdiff;h=d7e2d38c1f0ead2239808dd117577a99a3ad3cde

Thanks,

Hans
