also there is another problem I found out when resuming from suspend and I
forgot to mention: when I resume from suspend the backlight is turned off (the
screen is working and displaying some image, which is just hard to see as there
is no backlight at all). The only workaround I found is close the laptop lid
and open it again, which turn on the backlight, though it lock the screen and
trigger some lid-close events
