[Bug 1250027] Re: 10de:1056 [Lenovo ThinkPad T420s] Fails to boot with discrete graphics
Olli Helenius, as per http://download.lenovo.com/express/ddfm.html an
update is available for your BIOS (1.38). If you update to this
following https://help.ubuntu.com/community/BiosUpdate , does it change
anything?
If not, 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.
