Hi, I just updated to the latest version of ubuntu, and had a failure message during system restart. The message asked that I contact this email. It claims that the brightness settings are unsupported (code 1529448 thinkpad_acpi). I have an X1 Carbon Thinkpad with i7-5600U CPU with Intel HD Graphics 5500. The error occurs when I run Linux version 3.16.0-36-generic All is OK when I am using Linux version 3.16.0-34 Please let me know if you need any additional information. Kind regards, Sven PS: Just moved back to Ubuntu after five years with MacOS, and I am loving it! -- Sven Leyffer Senior Computational Mathematician Argonne National Laboratory ------------------------------------------------------------------------------ One dashboard for servers and applications across Physical-Virtual-Cloud Widest out-of-the-box monitoring support with 50+ applications Performance metrics, stats and reports that give you Actionable Insights Deep dive visibility with transaction tracing using APM Insight. http://ad.doubleclick.net/ddm/clk/290420510;117567292;y _______________________________________________ ibm-acpi-devel mailing list ibm-acpi-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/ibm-acpi-devel
