Another bit of trivia: /sys/devices/platform/toshiba_acpi/backlight/toshiba/max_brightness and /sys/devices/pci0000:00/0000:00:02.0/backlight/acpi_video0/max_brightness shows that there are 7 possible brightness values (running from 0 through 6 inclusive).
However, when I press the Fn+F6 and Fn+F7 buttons (to lower and raise the brightness), I only count 5 possible brightness levels (when the screen-brightness system is working at all). Is the GUI supposed to follow the number of brightness levels provided by the kernel? Some of the other /sys/*brightness* files use different units to measure/control the brightness, so are those the "real" brightness controls? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/832483 Title: Toshiba R835-P56X - screen brightness control does not work after suspend/resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/832483/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
