Ubuntu 16.04 (xenial) reached end-of-standard-support on April 29, 2021. I'm setting the status of this bug to 'Incomplete' as it's not seen any activity for some time. If this is still an issue when using a currently maintained release of Ubuntu then please let us know which one(s) otherwise this bug report can be left to expire in approximately 60 days time. ** Changed in: xorg (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1708829 Title: Unable to detect correct resolution of external monitor Status in xorg package in Ubuntu: Incomplete Bug description: My system is unable to detect the correct resolution of the monitor.
