I've got the same issue on a HP Pavilion dv6710ev My brightness control is under /proc/acpi/video/VGA/LCD/brightness
I can put the brightness to max using: sudo sh -c 'echo -n 95 > /proc/acpi/video/VGA/LCD/brightness' (95 is the highest value available, use cat /proc/acpi/video/VGA/LCD/brightness to get available values) As a workaround I put this line in /etc/rc.local before "exit 0" to get brightness maxed at every boot: echo -n 95 > /proc/acpi/video/VGA/LCD/brightness -- LCD Brightness on Laptop Always Set Very Low at Boot https://bugs.launchpad.net/bugs/12637 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
