Just to add that I am getting similar symptoms on a dual boot Dell 1558. When selecting Ubuntu from Grub, on some occasions I will be left with the blinking cursor in the extreme top left of the screen and this will either stay like this or move on to some garbled text with a red background.
When it does work, the blinking cursor appears, but then a command regarding Plymouth and SIGINT received appears on the screen, another command references AppArmour and then Ubuntu boots normally. I'm running 10.04 LTS. -- 10.04 failure to boot https://bugs.launchpad.net/bugs/573254 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
