Gilberto, thank you for reporting this and helping make Ubuntu better. As per http://www.dell.com/support/home/us/en/19/product- support/product/precision-t3400/drivers an update to your computer's buggy and outdated BIOS is available (A14). 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, if the problem is still reproducible, and the information above is provided, then please mark this report Status Confirmed. Otherwise, please mark this as Invalid. Thank you for your understanding. ** Tags added: latest-bios-a14 ** Tags removed: latest-bios-a14 ** Tags added: bios-outdated-a14 ** Changed in: xorg (Ubuntu) Importance: Undecided => Low ** Changed in: xorg (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1508901 Title: Resolution Dysplay Status in xorg package in Ubuntu: Incomplete Bug description: ACPI PDD failure error Display Black ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: xorg 1:7.7+1ubuntu8.1 ProcVersionSignature: Ubuntu 3.19.0-31.36~14.04.1-generic 3.19.8-ckt7 Uname: Linux 3.19.0-31-generic x86_64 NonfreeKernelModules: nvidia .proc.driver.nvidia.registry: Binary: "" .proc.driver.nvidia.version: NVRM version: NVIDIA UNIX x86_64 Kernel Module 340.93 Wed Aug 19 16:49:15 PDT 2015 GCC version: gcc version 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04) ApportVersion: 2.14.1-0ubuntu3.16 Architecture: amd64 Date: Thu Oct 22 09:57:20 2015 DistUpgraded: Fresh install DistroCodename: trusty DistroVariant: ubuntu DkmsStatus: bbswitch, 0.7, 3.19.0-31-generic, x86_64: installed nvidia-340, 340.93, 3.19.0-31-generic, x86_64: installed GraphicsCard: NVIDIA Corporation G84GL [Quadro FX 1700] [10de:040f] (rev a1) (prog-if 00 [VGA controller]) Subsystem: NVIDIA Corporation Device [10de:049a] InstallationDate: Installed on 2015-10-21 (0 days ago) InstallationMedia: Ubuntu-GNOME 14.04.3 LTS "Trusty Tahr" - Beta amd64 (20150805) MachineType: Dell Inc.
