Public bug reported: I tested this in Xubuntu and Lubuntu 15.04 and then in Xubuntu 14.04.
Xubuntu 14.04 recognized ALL the problem DVDs that 15.04 could not recognize. I tried using upstart at boot instead of systemd, the problem still persisted in 15.04. Sometimes, if I reboot using systemd with the DVD already inserted, the DVD is loaded. However, if I eject the DVD and re-insert it, it cannot be recognized again. However, one or two particularly stubborn DVDs still could not be recognized even with a reboot. Again, though, 14.04 had no problem recognizing these "stubborn" DVDs. I have tested, so far, about 30 original DVDs. 4 or 5 showed this problem in 15.04. Xubuntu 14.04 had no problems with these 4 or 5. I first posted this problem in the Ubuntu forums and at least one other user experienced the same problem (including flash drive recognition problems - I did not test this and, for me, no problems to date). http://ubuntuforums.org/showthread.php?t=2276987 ** Affects: libdvdread (Ubuntu) Importance: Undecided Status: New ** Tags: dvd read recognition -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1453366 Title: 15.04 (Xubuntu, Lubuntu) cannot recognize some DVDs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libdvdread/+bug/1453366/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
