Description

We should turn the device's screen off after a period of inactivity. This should be able to be done by adding a few lines to the xorg.conf file.

This seems to happen on the latest release (with bleeding edge kernel), but not as expected or regularly.

New FS builds seem to respond correctly, but the real problem is that it blanks the screen but doesn't turn off the backlight, so the screen goes bright white.

I think this can be fixed by using sleep/suspend methods on the backlight driver.

With a proper kernel and a new-ish FS this will work *if* you set a value to the backlight after boot (write into the sysfs file). Test and write the script to echo 255 > /sys/class/backlight/backlight/brightness on boot.

  • status changed from new to closed.
  • resolution set to fixed.

This appears to work; however, echoing 255 doesn't work. Echoing 254 works great though (you can test with xset dpms force off when X is running) so I put a script into the oswald-extras repo that echoes the value while X is starting.
