[Bug 1522944] Re: Wifi broken and strange screen resolution after update


Niklas Vainio, 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computer's buggy and outdated BIOS is available (1.40). If you update to
this following https://help.ubuntu.com/community/BIOSUpdate does it
change anything?

For more on BIOS updates and linux, please see

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:
1) Please provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
2) Please make a comment specifically advising on if there was an improvement or not.
3) If the issue is still reproducible, please mark this report Status Confirmed. Otherwise, please mark this as Invalid.

Thank you for your understanding.

  Wifi broken and strange screen resolution after update

Status in linux package in Ubuntu:

Bug description:
  After update from kernel 4.2.0-18 to 4.2.0-19, my wifi got broken and
  the video driver had some problems too, because my resolution was
  downgraded to 1024x768. Boot startup screen was changed from a
  graphics mode to a low resolution text mode (25x80 maybe).

  I had to boot back to 4.2.0-18 to report this bug. Please let me know
  what extra information is needed.
