All, Plasma/fw5 key-stroke handler is properly monitoring the 'function-F9' and 'function-F10' keys for backlight control (brightness down/up). However, when using the nvidia driver, the keystrokes are translated into updating the following in sysfs:
/sys/class/backlight/acpi_video0/brightness instead of /sys/class/backlight/nvidia_backlight/brightness Setting the first (range 0-20) has no effect on backlight and must be translated to a range of 0-127 for the nvidia setting. Where would I look in the source code to find what is handling the brightness function keys? kdelibs? kdebase? -- David C. Rankin, J.D.,P.E.
