[Bug 1391758] Re: [Asus UX32VD] Backlight controls have no effect after suspend in most recent kernel
Hi, After updating the BIOS, the backlight control works once more. In fact, I can now also turn off the backlight completely with the same controls, which was not possible before. Furthermore, the backlight control is more fine-grained than before. It seems that the problem is fixed. Thanks. ** 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/1391758 Title: [Asus UX32VD] Backlight controls have no effect after suspend in most recent kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1391758/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

RK, thank you for reporting this and helping make Ubuntu better. As per http://www.asus.com/us/Notebooks_Ultrabooks/ASUS_ZENBOOK_UX32VD/HelpDesk_Download/ an update to your BIOS is available (214). 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. Thank you for your understanding. ** Tags added: bios-outdated-214 ** Changed in: linux (Ubuntu) Importance: Undecided = Low ** Changed in: linux (Ubuntu) Status: Confirmed = Incomplete -- You received this bug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/1391758 Title: [Asus UX32VD] Backlight controls have no effect after suspend in most recent kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1391758/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
