Shaun Duncan, as per http://www.dell.com/support/troubleshooting/us/en/19/Product/xps-13 -l321x-mlk an update is available for your BIOS (A10). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything?
If not, 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 Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Thank you for your understanding. ** Tags added: bios-outdated-a10 ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete ** Attachment removed: "lspci-vnvn.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1232459/+attachment/3847174/+files/lspci-vnvn.log ** Attachment removed: "version.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1232459/+attachment/3847173/+files/version.log ** Summary changed: - Brightness control broken for Dell XPS 13 on Raring 13.04 after kernel upgrade + [Dell XPS 13 L322X] Brightness control broken on Raring 13.04 after kernel upgrade -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1232459 Title: [Dell XPS 13 L322X] Brightness control broken on Raring 13.04 after kernel upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1232459/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
