When I run the 3.16 kernel in 14.04.2, both monitors on my dual monitor setup shut down with loss of signal until the system comes to the Unity login screen. When I run either 3.13 or 3.14 kernels there is no problem.
I have found that commenting out lines in the /etc/grub.d/10_lupin file and setting vt_handoff=1 to vt_handoff=0 in the /etc/grub.d/10_linux file will allow the plymouth screen to display properly on a 3.16 kernel. Whatever the 3.16 kernels do differently seems to prevent the plymouth screen from displaying on boot unless vt_handoff is disabled in a file (two files if the user is running Ubuntu in a Wubi install). The relevant lines in the /etc/grub.d/10_lupin file to disable by commenting them out are as follows: #for word in $GRUB_CMDLINE_LINUX_DEFAULT; do # if [ "$word" = splash ]; then # GRUB_CMDLINE_LINUX_DEFAULT="$GRUB_CMDLINE_LINUX_DEFAULT \$vt_handoff" # fi #done After that, plymouth displays correctly every bootup. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1425304 Title: Plymouth does not display correctly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-meta-lts-utopic/+bug/1425304/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
