Public bug reported: [Ubuntu 10.04 LTS kernel through upstream kernel version 2.6.34-rc6]
Kernel boot param "acpi_backlight=video" does not enable backlight support as intended. Setting it actually ends up enabling the video output switching feature (the same as "acpi_display_output=video" does). It is not possible to force backlight support, since no code ever enables ACPI_VIDEO_BACKLIGHT_FORCE_VIDEO. ** Affects: linux (Ubuntu) Importance: Undecided Assignee: Kamal Mostafa (kamalmostafa) Status: In Progress ** Changed in: linux (Ubuntu) Status: New => In Progress ** Changed in: linux (Ubuntu) Assignee: (unassigned) => Kamal Mostafa (kamalmostafa) -- acpi_backlight=video does not work https://bugs.launchpad.net/bugs/573120 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
