Re: Packard Bell EasyNote LV need i915.invert_brightness=1

[Petter Reinholdtsen 2013-06-03] According to modinfo i915, I should report machines/video cards needing the invert_brightness=1 setting here. The laptop in question is described on URL: http://www.linlap.com/packard_bell_easynote_lv . The screen go black as soon as the i915 kernel module

[Petter Reinholdtsen 2013-06-11] Sure. This is my first try, so I hope I got it right. Does the silence mean I got the kernel patch formatting right, or that I should try again? URL: http://lists.freedesktop.org/archives/dri-devel/2013-June/039787.html contain the complete patch

Re: Packard Bell EasyNote LV need i915.invert_brightness=1

instead of using the acpi_backlight interface it is using the intel_backlight interface, which is not inverted. So I wonder, perhaps i915.invert_brightness=1 is the wrong quirk for this machine? -- Happy hacking Petter Reinholdtsen ___ dri-devel mailing

(never seen which should increase or decrease the brighness), so it might be inverted. Is it possible to tell acpi_backlight to invert the brighness setting? Would it affect i915 too? -- Happy hacking Petter Reinholdtsen ___ dri-devel mailing list dri-devel

it. Right. I guess my findings above mean the hardware should be blacklisted (from acpi?). Is there no way to discover using ACPI if the backlight brightness setting should be inverted or not? -- Happy hacking Petter Reinholdtsen ___ dri-devel mailing
