[Bug 1492137] Re: Brightness keys (fn+f5/f6) not working, UX305FA
--- acpi_osi removed from kernel parameters in grub --- Hotkeys still not working, brightness applet working. By https://wiki.ubuntu.com/Kernel/Debugging/Backlight I am in the following situation: "Backlight control works through the brightness applet but not via hotkeys." Thereafter following the link on debugging hotkeys https://wiki.ubuntu.com/Hotkeys/Troubleshooting Results from step-by-step troubleshooting: - Nothing registered with xev when pressing fn+f5/f6 (backlight down/up) - Nothing registered with evtest when pressing fn+f5/f6 - Nothing registered with acpi_listen when pressing fn+f5/f6 (other fn-key functions such as turning off the touchpad are registered) Also, please find the files produced by commands under "Useful Information to Collect in Reports" attached. --- WORKAROUND in https://wiki.ubuntu.com/Kernel/Debugging/Backlight --- Booting with only acpi_backlight=vendor, adjusting the brightness through the applet stops working as well. The brightness changes when executing "echo 8 > /sys/class/backlight/intel_backlight/brightness". Booting with only video.use_bios_initial_backlight=0, brightness applet works, but not the brightness hotkeys. Booting with only acpi_osi=, neither applet nor hotkeys work. Booting with only video.use_native_backlight=1, applet works but not hotkeys. Also, please find vendorbacklight and lslabacklight files attached. --- Kernel v4.5-rc4-wily --- Problem still exists -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1492137 Title: Brightness keys (fn+f5/f6) not working, UX305FA To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1492137/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Daniel, anything change if you remove the non-default kernel boot parameter: acpi_osi=Linux If not, then could you please advise to the WORKAROUNDs noted in https://wiki.ubuntu.com/Kernel/Debugging/Backlight ? Also, in order to upstream this, could you please test the latest mainline kernel (4.4) and advise to the results? ** 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/1492137 Title: Brightness keys (fn+f5/f6) not working, UX305FA To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1492137/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The bug also exists when testing on upstream kernel v4.3-rc6-unstable. ** Tags added: kernel-bug-exists-upstream kernel-bug-exists- upstream-4.3-rc6 ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1492137 Title: Brightness keys (fn+f5/f6) not working, UX305FA To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1492137/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1492137] Re: Brightness keys (fn+f5/f6) not working, UX305FA
Daniel, thank you for reporting this and helping make Ubuntu better. Could you please test the latest upstream kernel available from the very top line at the top of the page from http://kernel.ubuntu.com/~kernel- ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and please do not test the daily folder)? Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow additional upstream developers to examine the issue. If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: kernel-fixed-upstream kernel-fixed-upstream-X.Y-rcZ Where X, Y, and Z are numbers corresponding to the kernel version. If the mainline kernel does not fix the issue, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream. Once testing of the latest upstream kernel is complete, please mark this report's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags added: latest-bios-210 ** Package changed: xorg (Ubuntu) => linux (Ubuntu) ** Changed in: linux (Ubuntu) Importance: Undecided => Medium ** Changed in: linux (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1492137 Title: Brightness keys (fn+f5/f6) not working, UX305FA To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1492137/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
