I'm also affected by this on Ubuntu 12.10, a workaround is to set the desired default backlight brightness by adding
# brightness fix after boot echo 0 > /sys/class/backlight/acpi_video0/brightness before exit 0 in /etc/rc.local. 0 is the minimum, usually, 0-15 can be used. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1069186 Title: problem with backlight To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1069186/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
