@everyone,
your workaroundy solutions with samsung-backlight are all nice and cute, but
please bear in mind that not only Samsungs are affected!
Laptops from MSI (PR200, Wind) have the same problem. Using
acpi_backlight=vendor stops the flicker, but also disables any kind of
backlight control, because the keys don't work by themselves and
/sys/class/backlight structure is gone.
Interestingly, using acpi_backlight=vendor leads to a situation where keyboard
doesn't send the backlight keycodes anymore, but /dev/input/event5 ("Video
Bus") still sends the keypresses as it should. So it's a half-there half-gone
solution.
