I've taken a look at the mainline kernel index to get the next 3.5 kernel after 3.5.4 for testing - however, there is no next 3.5 kernel. The kernel following 3.5.4 is 3.6-rc1.
As none of the mainline kernels exhibits the bug, apparently one of the modifications that Ubuntu did to the mainline kernel is the cause for the black screen during boot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1057532 Title: Monitor goes black ("no signal") after Grub, comes back to life when X starts To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1057532/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
