Updated to 4.19-rc7 (uname -r = `4.19.0-041900rc7-generic`) with 'Ubuntu Kernel Update Utility'. Without any boot parameters, brightness still doesn't function (but UI shows it changing).
Are there any other things you want me to try on this kernel? Unfortunately a lot of other things seemed to break on this kernel, including Nvidia modules, which didn't seem to compile. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1784878 Title: Backlight Not Functional - Origin EVO 15-S (Clevo) Status in linux package in Ubuntu: Triaged Bug description: Backlight slider moves, and values updated in /sys/class/backlight/intel_backlight/actual_brightness however, backlight does not actually change.
