--- Comment #17 from Jozef Peterka <[email protected]> --- I would say Aaron is right - this is definitely not a bug of Intel driver - which works for me on the same hardware - same laptop. I am no expert but I would say you are using nouveau driver, which is activated upon the Fedora (and probably other distros too) installation and upon detection of Nvidia chip in your (our) laptop. By following this guide: https://fedoraproject.org/wiki/Bumblebee#For_closed_source_solution you would essentially disable nouveau driver, which is buggy to say the least on your very recent hardware, activate Intel driver and install Nvidia closed sourced (proprietary) driver. After this remove the nomodeset option from kernel line in grub and I am sure your back-light will work just fine. Not to mention the possibility to use your high performance graphics on demand by using primusrun/optirun commands. If not, I would suggest opening a thread in support forums of the distro - other, more smart people might help you. Anyways, if a bug should be filled, it should be filled in against nouveau driver, which needs nomodeset option on our laptop to even boot into X, not the Intel one which works fine (at least in regards mentioned earlier). Or you could fill a bug against Fedora - in a sense that you should be able to choose between nouvau/Intel driver during the install process perhaps.
