I have Xubuntu 12.10 running fine on a Thinkpad T60. Grub2 is installed as the boot manager and the GRUB....LINUX_DEFAULT is set as "quiet splash". Therefore, Grub should display its splash image until plymouth takes over, as I understand it. Unfortunately, it does not. If I hold down shift to get into the boot menu, my splash image shows up, but the screen remains black. I realise it's a minor cosmetic issue, but I have found no way to fix it.
