I experience similar results with my Lenovo T61p on CentOS 5.3 after sliding gnome power manager "running on AC" brightness to max:
# cat /proc/acpi/ibm/brightness level: 7 commands: up, down commands: level <level> (<level> is 0-15) after using Fn + Home to increase brightness to max: # cat /proc/acpi/ibm/brightness level: 15 commands: up, down commands: level <level> (<level> is 0-15) # cat /sys/class/backlight/acpi_video0/max_brightness cat: /sys/class/backlight/acpi_video0/max_brightness: No such file or directory # cat /sys/class/backlight/thinkpad_screen/max_brightness 15 -- Max brightness is not max brightness https://bugs.launchpad.net/bugs/203096 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-power-manager in ubuntu. -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
