On my shiny new X200 running Fedora Rawhide, I'm finding that the
brightness control keys work OK, but the backlight remains stuck off
after a resume. The machine is working fine but the backlight is just
off; I can see the display under a bright light. Switching consoles and
poking about in /sys/class/backlight/acpi_video?/ didn't help.
