Are you using intel_backlight or acpi_video? From your comment #1, it seems you are using acpi_video interface. Does intel_backlight have any problem? > > 1. The first boot afterwards happens with level 0 (the old level is not used) The black screen happens when GUI starts? > > 2. Level 0 now turns the screen off, which didn't happen before (v3.6; the > last time the backlight driver worked correctly) So we are talking about acpi_video interface, right? > > 3. Each time the backlight level is changed through X, a flash happens > (level 100%, level 0%, and then the desired level). It works fine through > sysfs though. I'll prepare a debug patch to see what happened, thanks. -- You are receiving this mail because: You are watching the assignee of the bug. ------------------------------------------------------------------------------ Get your SQL database under version control now!
