[Bug 1515423] Re: External monitors are not detected

 

Jose, thank you for reporting this and helping make Ubuntu better.

As per https://support.apple.com/en-us/HT201518 an update to your
computer's buggy and outdated BIOS is available (MBP81.0047.2AB
(2015-001)). If you update to this following
https://help.ubuntu.com/community/BIOSUpdate does it address the issue?

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.

Also, you don't have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible, and the
information above is provided, then please mark this report Status
Confirmed. Otherwise, please mark this as Invalid.

Thank you for your understanding.
