HI,
I have found that I need to use i915.invert_brightness=1 for my HP
Envy 17 with a Haswell processor (i7-4702MQ). The lspci command shows
the following information about this device:
$ lspci -v -s 00:02.0
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core
Processor Integrated Graphics Controller (rev 06) (prog-if 00 [VGA
controller])
Subsystem: Hewlett-Packard Company Device 1968
Flags: bus master, fast devsel, latency 0, IRQ 43
Memory at d3000000 (64-bit, non-prefetchable) [size=4M]
Memory at c0000000 (64-bit, prefetchable) [size=256M]
I/O ports at 6000 [size=64]
Expansion ROM at <unassigned> [disabled]
Capabilities: <access denied>
Kernel driver in use: i915
Operating system information:
Fedora 20 (beta)
Linux kernel version 3.11.3
Please let me know if you need any additional information.
Best regards,
Fred New

I am surprised... until recently [1] we've only seen this on gen4 Acer

Please file a new bug on DRM/Intel at [2], and attach the same info as

Fred, did you end up filing the bug? I don't think I saw one...
Please try video.use_bios_initial_backlight=0 module parameter (without
i915.invert_brightness). Does that help?

Jani.
