Jozef Peterka <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #6 from Jozef Peterka <[email protected]> --- Hello all and thanks for this thread. I don't know what you would need, but as I have the same XPS 15 9550 with Intel/Nvidia 960M I can confirm that when I removed nomodeset kernel parameter the backlight started to work on Fedora 23, kernel 4.3.5. When I installed bumblebee stuff, the nouveau was disabled all around, but the original kernel parameter I set to be even able to start X (with nouveau) was left in GRUB config. In this state, when I tried to ls /sys/class/backlight it was all empty. Now that I removed nomodeset param, I got: [kai@localhost ~]$ ls /sys/class/backlight/ intel_backlight which works flawlessly. I can also comment on why the original reporter most probably had the nomodeset. This has to be related to nouveau driver because when I want to start Fedora23/Install in X, I had to use nomodeset boot options, otherwise the GUI/X won't start with lots and lots of error messages on the background. Anyways, thanks to all of you and also the original reporter for this thread! -- You are receiving this mail because: You are watching the assignee of the bug. ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
