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.
Intel graphics, right?
Yes. The new, erm , X4500?
The DRM layer should handle full resume on modern
Intel hardware, but there's the potential for bugs. This is entirely
unrelated to ACPI, though.
OK, that's a good clue. I poke at acpi to change the brightness, so I'd
assumed that acpi would also handle turning the backlight on/off.
I'm using the rawhide rather than standard kernel, but I'd thought they
were fairly similar.
I'm also using the vesa X server; I haven't tried using the intel one yet.
