Christopher Barrington-Leigh, thank you for reporting this and helping make Ubuntu better. As per http://support.lenovo.com/us/en/products /laptops-and-netbooks/thinkpad-x-series-tablet- laptops/thinkpad-x230-tablet an update to your computer's buggy and outdated BIOS is available (2.60). 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, and the information above is provided, then please mark this report Status New. Thank you for your understanding. ** Tags added: bios-outdated-2.60 ** Changed in: xorg (Ubuntu) Importance: Undecided =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/1371704 Title: flickering stripes/dashes screen corruption following recent update in 14.04 Status in xorg package in Ubuntu: Incomplete Bug description: After a regular update of my LTS during the last week, the screen has started showing corruption. For instance, when I maximise a window, the screen flickers for up to a second with an overlay of black dashes and stripes, sometimes in a chevron pattern or just horizontal black dashes covering the whole screen, especially on an external display. It does not show up in a screen capture.
