Thank you for reporting this bug to Ubuntu. Ubuntu 17.10 (artful) reached end-of-life on July 19, 2018.
See this document for currently supported Ubuntu releases: https://wiki.ubuntu.com/Releases We appreciate that this bug may be old and you might not be interested in discussing it any more. But if you are then please upgrade to the latest Ubuntu version and re-test. If you then find the bug is still present in the newer Ubuntu version, please add a comment here telling us which new version it is in and change the bug status to Confirmed. ** Package changed: xorg (Ubuntu) => xorg-server (Ubuntu) ** Changed in: xorg-server (Ubuntu) Status: New => Won't Fix -- 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/1766015 Title: Session crashes, returning to login screen Status in xorg-server package in Ubuntu: Won't Fix Bug description: Sometimes, while using my computer, everything on the screen just freezes (but audio keeps playing) and then a couple seconds later, everything is black (and audio stops at this point), and then I am brought back to the login screen. In addition, the numlock light on my keyboard is lit up, but numlock is actually turned off, requiring me to hit the numlock key again. I don't know if using two HDMI monitors at once is relevant or not.
