I will have to search for that. actually i see the backlight controls in: /proc/acpi/video/NGFX/LCD/brightness /proc/acpi/video/NGFX/CRT/brightness /proc/acpi/video/NGFX/HDMI/brightness /sys/devices/virtual/backlight/acpi_video0/brightness /sys/devices/pci0000:00/0000:00:1c.0/0000:02:00.0/leds/ath9k-phy0::radio/brightness /sys/devices/pci0000:00/0000:00:1c.0/0000:02:00.0/leds/ath9k-phy0::assoc/brightness /sys/devices/pci0000:00/0000:00:1c.0/0000:02:00.0/leds/ath9k-phy0::tx/brightness /sys/devices/pci0000:00/0000:00:1c.0/0000:02:00.0/leds/ath9k-phy0::rx/brightness /sys/devices/pci0000:00/0000:00:1c.1/0000:03:00.0/leds/mmc0::/brightness /sys/devices/pci0000:00/0000:00:1c.1/0000:03:00.4/leds/mmc1::/brightness for example. some of these are led's for network and sd card slots, not the screen.brightness controls also floating about in /proc on another laptop with a radeon it's: /proc/acpi/video/VGA/DFP1/brightness /proc/acpi/video/VGA/TV/brightness /proc/acpi/video/VGA/CRT/brightness /proc/acpi/video/VGA/LCD/brightness as well as more in /sys... pick the one thats used :) (probably LCD). i've found others in other weird places. but whenever xrandr doesn't work - the fallback is to go to /proc or /sys - also dont assume users will have the latest and greatest of drivers and kernels so even if a newer driver does work, an older may not, so need to go to /proc or /sys > >> - a nice little box indicating the backlight level when it is changed > >> (edje kind of thing, related to themes). > > > > steal all the code from mixer gadget - for its gadget and popup. thats what > > u need there. :) > > > >> - find a way to update backlight when modified by an other program > >> (xbacklight for instance). > > > > for now i'd say use a poller like battery and temperature and make it poll > > by default every 32ticks (4seconds). allow setting poll interval. should > > also GET the backlight value first every time you try and modify it. > > It was more or lest my intention, i.e. I will use a timer and check that > backlight property did not change outside e17. it is simple to do that. > I will code that today if I have time. use a poller, not timer. :) see other modules like above :) -- ------------- Codito, ergo sum - "I code, therefore I am" -------------- The Rasterman (Carsten Haitzler) ras...@rasterman.com ------------------------------------------------------------------------------ Achieve unprecedented app performance and reliability What every C/C++ and Fortran developer should know.
