Some sort of workaround: 1) add udev rule /etc/udev/rules.d/90-backlight.rules: ACTION=="add", SUBSYSTEM=="backlight", RUN+="/bin/chgrp video /sys/class/backlight/%k/brightness" ACTION=="add", SUBSYSTEM=="backlight", RUN+="/bin/chmod g+w /sys/class/backlight/%k/brightness"
2) add yourself to group video: sudo usermod -a -G video $USER 3) run: sudo udevadm control -R && sudo udevadm trigger -c add -s backlight -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1638136 Title: xbacklight not working in ubuntu 16.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xbacklight/+bug/1638136/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
