Merlijn Sebrechts, no need to further e-mail any mailing list at this time. Anyone who is interested will look at the downstream report.
Despite this, the next step is to fully reverse commit bisect from kernel 3.14 to 3.18-rc7 in order to identify the last bad commit, followed immediately by the first good one. Once this commit has been identified, then it may be reviewed as a candidate for backporting into your release. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ? Please note, finding adjacent kernel versions is not fully commit bisecting. Thank you for your understanding.

The following workaround worked: http://askubuntu.com/a/450594 It adds a config file to /usr/share/X11/xorg.conf.d/ adding acpi_backlight=vendor to boot params did nothing adding acpi_osi=Linux to boot params only fixed the keyboard shortcuts, but the screen indicator and the brightness settings dialog stopped working. Please let me know if this is not the right package, or if you need more info.
