There is a related bug on the kernel bug tracker: https://bugzilla.kernel.org/show_bug.cgi?id=21012 for Kernel 3.2.
I tried the workaround suggested in comment 19 but this stops my laptop going in sleep mode. Any ideas how to modify this script to make it work? ----------------- #!/usr/bin/env sh # /etc/pm/sleep.d/99toshiba if [ $1 == suspend ] then cat /sys/class/backlight/intel_backlight/brightness > /var/run/brightness elif [ $1 == resume ] then echo 3 > /sys/class/backlight/toshiba/brightness cat /var/run/brightness > /sys/class/backlight/intel_backlight/brightness fi ** Bug watch added: Linux Kernel Bug Tracker #21012 http://bugzilla.kernel.org/show_bug.cgi?id=21012 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1069144 Title: [Toshiba Satellite R830] brightness control works until sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1069144/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
