Ubuntu 14.04 random screen freeze while Normal OS activites

[Jerome Rousselot]

Bug is very similar to 1184451

Intel driver, intermittent black screens between 1 and 10 s.

Using the keyboard, moving the mouse, switching terminals help bringing back graphics.

Bug occurs without significant CPU activity.

My computer is almost unusable for work.

Jerome Rousselot, 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-laptops/thinkpad-x220 an update to your computer's buggy and outdated BIOS is available (1.39). 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.
