I tried also: sudo su -c 'echo 10 > /sys/class/backlight/acpi_video0/brightness'.
Pressing the Fn keys brings up the OSD brightness control, which reflects the value of the /sys/class/backlight/acpi_video0/brightness file (and viceversa), but the actual screen brightness does not change. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1720438 Title: brightness control broken nvidia To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/1720438/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
