ligi, thank you for reporting this and helping make Ubuntu better. As per http://support.lenovo.com/us/en/products/Laptops-and- netbooks/ThinkPad-T-Series- laptops/ThinkPad-T520?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an update to your computer's buggy, insecure, and outdated BIOS is available (1.45). 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. ** Summary changed: - follow-up to [Lenovo ThinkPad W530] Regression: cannot set up 3 display configuration any more (Optimus) #1556459 + [Lenovo ThinkPad T520] Regression: cannot set up 3 display configuration any more (Optimus) ** Description changed: - as requested in #1556459 - - this is the bug created by "ubuntu-bug xorg" with xdiagnose installed - - shortly after trying to enable the 3rd monitor and the error showed + Shortly after trying to enable the 3rd monitor and the error showed.
