[Kernel-packages] [Bug 1399611] Re: Screen brightness not working acer aspire 5742
Thanks. I updated my bios using freedos (which was surprisingly easy to do!). sudo dmidecode -s bios-version sudo dmidecode -s bios-release-date V1.30 08/13/2012 This does not fix the problem. If I restart my laptop without the workaround, the effect is still the same. When I change brightness, I see the slider changing, but the brightness stays the same. ** Changed in: linux (Ubuntu) Status: Incomplete = Confirmed -- 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/1399611 Title: Screen brightness not working acer aspire 5742 Status in linux package in Ubuntu: Confirmed Bug description: My laptop does not respond to the screen brightness control after default Ubuntu install.

Merlijn Sebrechts, as per http://us.acer.com/ac/en/US/content/drivers an update to your BIOS is available (1.30). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version sudo dmidecode -s bios-release-date For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, then please mark this report Status Confirmed.

Did this issue occur in a previous version of Ubuntu, or is this a new issue? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.18 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as Confirmed. Thanks in advance.

removing the workaround (intel.conf file in /usr/share/X11/xorg.conf.d/) and booting with the latest vivid kernel (3.18.0-031800rc7-generic #201411302035) did not fix the problem.

The following workaround worked: http://askubuntu.com/a/450594 It adds a config file to /usr/share/X11/xorg.conf.d/ adding acpi_backlight=vendor to boot params did nothing adding acpi_osi=Linux to boot params only fixed the keyboard shortcuts, but the screen indicator and the brightness settings dialog stopped working. Please let me know if this is not the right package, or if you need more info.
