Thanks for testing. I can perform a bisect to identify the commit that introduced the regression. We first need to know the last good kernel and the first bad kernel version. We know the 4.4.0-62 is good and 4.4.0-64 is bad. Can you test the 4.4.0-63 kernel, which can be downloaded from:
https://launchpad.net/~canonical-kernel- team/+archive/ubuntu/ppa/+build/11016267 For this kernel, you need to install both the linux-image and linux- image-extra .deb packages. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1667323 Title: Backlight control does not work and there are no entries in /sys/class/backlight To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1667323/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
