Max Oropeza, thank you for updating your BIOS. Could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the mainline kernels archive directory daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER
where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.11-rc3 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags: kernel-unable-to-test-upstream kernel-unable-to-test-upstream-VERSION-NUMBER Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags removed: bios-outdated-v1.30 ** Tags added: latest-bios-v1.30 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1173961 Title: [Gateway NV55C] Two backlight interfaces that wont adjust backlight. Status in “linux” package in Ubuntu: Incomplete Bug description: I couldn't get the backlight to work after I upgraded to 13.04. WORKAROUND: The only grub lines that seem to work are these: GRUB_CMDLINE_LINUX="acpi_osi=Linux acpi_backlight=vendor" GRUB_CMDLINE_LINUX="acpi_osi=" I tried changing the grub parameters, and after several trys, nothing. I was asked to run grep . /sys/class/backlight/*/* and got the results of: maxo@Dayman:~$ grep . /sys/class/backlight/*/* /sys/class/backlight/acpi_video0/actual_brightness:9 /sys/class/backlight/acpi_video0/bl_power:0 /sys/class/backlight/acpi_video0/brightness:9 grep: /sys/class/backlight/acpi_video0/device: Is a directory /sys/class/backlight/acpi_video0/max_brightness:9 grep: /sys/class/backlight/acpi_video0/power: Is a directory grep: /sys/class/backlight/acpi_video0/subsystem: Is a directory /sys/class/backlight/acpi_video0/type:firmware /sys/class/backlight/intel_backlight/actual_brightness:976 /sys/class/backlight/intel_backlight/bl_power:0 /sys/class/backlight/intel_backlight/brightness:976 grep: /sys/class/backlight/intel_backlight/device: Is a directory /sys/class/backlight/intel_backlight/max_brightness:976 grep: /sys/class/backlight/intel_backlight/power: Is a directory grep: /sys/class/backlight/intel_backlight/subsystem: Is a directory /sys/class/backlight/intel_backlight/type:raw But using the Fn Keys, you can only adjust it a little, like from full brightness to about half. To add something else, with the other parameters when I adjust with the Fn Keys, the brightness bubble you get on the top right of your screen doesn't appear.
