Package: src:linux Version: 3.14.13-2 On Lenovo (my other non-Lenovo are fine) G580, switching from X on tty7 to any of tty1...6 gives a very dim screen. So one must hit Fn Up Arrow (or Fn Down Arrow), after which one can read the screen again. Switching back to tty7 and then back again to tty1-6 recreates the problem.
Running printf '%3d %3d %3d | %3d %3d %3d\n' $( cat \ /sys/class/backlight/intel_backlight/*brightness \ /sys/class/backlight/acpi_video0/*brightness ) before and after hitting a Fn Down Arrow shows 7 7 976 | 15 15 15 838 838 976 | 14 14 15 Therefore something is messing with /sys/class/backlight/intel_backlight/brightness , knocking it down to 7, when it should keep its hands off! -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
