Thank you for reporting this bug to Ubuntu. Ubuntu 15.04 (vivid) reached end-of-life on February 4, 2016.
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. ** Changed in: xorg (Ubuntu) Status: Confirmed => 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/1448574 Title: Have to use nomodeset for install (new problem for new distro) Status in xorg package in Ubuntu: Won't Fix Bug description: I haven't had this problem since around version 12.04 or before (can't recall which one precisely) where, during installation, I have to use nomodeset in order to get my Samsung television to stop turning on and off repeatedly during modeset problems. I would like to mention that my television doesn't support an automatic shutoff mode which would normally cause it to turn off in a powersave situation, so being able to do that would be considered a new feature to me (one maybe worth exploring later). However, this last distro of 15.04 seems to have brought back the old problems with modeset that were once fixed, brought back, fixed again, and now brought back once more. Unfortunately, I can't give a log of this error due to the nature of the problem causing no visuals and my system deleting any log files upon reboot of the live boot. So, all I can suggest is to look into what changed that would cause modeset to break like this and try to change it back or add-in the fix to the code that existed before, if possible. Thanks!
