After installing Raring on my 2013 MacBook Air 6,2, I find that sometimes when resuming from suspend, the screen is dark. I have tracked this down to the i915 driver, where the screen brightness can be adjusted between levels 0-15. This works correctly after boot, with 0 being dark and 15 the brightest.
Sometimes after suspend/resume, the screen is equally dark between levels 0-12, and seems to be equally bright for levels 13-15 (brightest). I say sometimes, because it's not every time. It _might_ be after the second or third suspend/resume, but I'm not yet sure how to repeat it.
When this happens, I have to kill lightum, the backlight/keyboard monitoring daemon, and manually set the brightness using the sys filesystem:
echo '15' | sudo tee /sys/devices/pci0000\:00/0000\:00\:02.0/backlight/acpi_video0/brightness
