[Bug 1388636] Re: [Lenovo V570 Notebook] Brightness not changing via UI widget in GNOME shell or hotkeys
** Description changed: Fresh install of a Vivid Vervet Ubuntu GNOME daily iso. Adding debugging information from https://wiki.ubuntu.com/Kernel/Debugging/Backlight I found that echo 8 /sys/class/backlight/intel_backlight/brightness worked to lower my screen brightness, without playing with kernel parameters. Booting with the kernel parameter: acpi_backlight=vendor did not enable the UI widget or hotkeys, although echo 8 /sys/class/backlight/intel_backlight/brightness continued to work. Booting with the kernel parameter: video.use_bios_initial_backlight=0 did not allow for hotkey or widget changes of brightness. - Booting with the kernel parameter: video.use_native_backlight=1 + Booting with the kernel parameter: video.use_native_backlight=1 also did + not resolve the issue. Creating /usr/share/X11/xorg.conf.d/80-backlight.conf with the contents: Section Device - Identifier Intel Graphics - Driver intel - Option AccelMethod sna - Option Backlight intel_backlight # use your backlight that works here - BusID PCI:0:2:0 + Identifier Intel Graphics + Driver intel + Option AccelMethod sna + Option Backlight intel_backlight # use your backlight that works here + BusID PCI:0:2:0 EndSection and rebooting does resolve the issue.

[Bug 1388636] Re: [Lenovo V570 Notebook] Brightness not changing via UI widget in GNOME shell or hotkeys
Asif Youssuff, could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing in your release) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. 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 exactly shown as: kernel-fixed-upstream-3.18-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. If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-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-44cn43ww ** Tags added: latest-bios-44cn43ww ** Changed in: linux (Ubuntu) Status: Confirmed = Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1388636 Title: [Lenovo V570 Notebook] Brightness not changing via UI widget in GNOME shell or hotkeys To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1388636/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
