Gunnar Koppel, thank you for reporting this and helping make Ubuntu better.
As per http://support.lenovo.com/us/en/products/Desktops-and-all-in- ones/ThinkCentre-M-Series- desktops/ThinkCentre-M55?tabName=Downloads&linkTrack=Mast:SubNav:Support:Drivers%20and%20Software|Drivers%20and%20Software&beta=false an update to your computer's buggy, insecure, and outdated BIOS is available (2MKT49A). When you update to this following https://help.ubuntu.com/community/BIOSUpdate how does this improve the situation? 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. Also, you don't have to create a new report. It is most helpful that after the BIOS is updated, if the problem is still reproducible: 1) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on how this improves the situation. 3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid. Thank you for your help. ** Tags added: bios-outdated-2mkt49a ** Changed in: xorg (Ubuntu) Importance: Undecided =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 Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1616113 Title: Occasionally mouse cursor get stucked, internally i915 driver seems to be culprit Status in xorg package in Ubuntu: Incomplete Bug description: I documented my problem here: http://askubuntu.com/questions/795970/lubuntu-14-04-mouse-cursor-stucks-occasionally tl;tr Mouse cursor stucks on certain events (clicking on Back-button in Chromium-brouser triggers it every time), and then in logs are following lines: [drm] stuck on render ring [drm] GPU crash dump saved to /sys/class/drm/card0/error [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
