I think I should elaborate on my previous post. I have 2 entries in /sys/class/backlight acpi_video0 intel_backlight
When I use the slider in the brightness applet or the hotkeys to change the brightness, the value of /sys/class/backlight/acpi_video0 is changing. This being the case, I believe that if I could point both of those to /sys/class/backlight/intel_backlight/brightness the problem would be solved. This is where I fall down as I do not know how to do this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1307064 Title: Ubuntu 14.04 Beta cannot adjust brightness on Lenovo Ideapad Z570 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1307064/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
