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/1620065 Title: intermittent black screen on bootup Status in xorg package in Ubuntu: Incomplete Bug description: sometimes when I boot up, the screen stays black. Only the mouse cursor works, and control-alt-f1 gives a useable screen. Rebooting from there usually gives me a clean bootup, but sometimes it takes several efforts.
