Jens Askengren, as per www.dell.com/support/home/us/en/04/product-support/product/xps-l702x/drivers an update to your BIOS is available (A19). 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 New. Thank you for your understanding. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1391652 Title: 30 sec Xorg freeze - ACPI Warning: \_SB_.PCI0.PEG0.PEGP._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20131115/nsarguments-95) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1391652/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
