Sean Brisbane, as per http://download.lenovo.com/express/ddfm.html an update to your BIOS is available (1.46). 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
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. ** Description changed: After closing my laptop lid and allowing it to suspend to RAM, the system would not resume properly. The visuals on the GUI returned to its previous state without any artifacts, however the mouse pointer was not working. I used a trackpad and a nipple on my T420 laptop. I left it in this state and the mouse was still dead after about 3-4 minutes. After coming back from making a cup of tea the mouse moved but did not interact with any GUI elements. I have seens some success on previous ubuntu versions if I did a tty switch. This did not work (ctrl+alt+F1), the Unity GUI stayed visible. I then tried the sysreq triggers alt+sysreq RE and lost the mouse pointer again, but the gui stayed visible. I needed to go through the whole alt+sysreq+reisub to make the machine reboot. + WORKAROUND: Using the proprietary nvidia drivers fixes the issue: + sudo apt-get install nvidia-304-updates --install-recommends + ProblemType: KernelOops DistroRelease: Ubuntu 14.04 Package: linux-image-3.13.0-20-generic 3.13.0-20.42 [modified: boot/vmlinuz-3.13.0-20-generic] ProcVersionSignature: Ubuntu 3.13.0-20.42-generic 3.13.7 Uname: Linux 3.13.0-20-generic x86_64 Annotation: This occured during a previous suspend and prevented it from resuming properly.
