Not sure how to mark this bug. When booting without "nomodeset" and with the module "nouveau" active, the screen will freeze minutes after showing Unity. When booting with "nomodeset" and with or without the module "nouveau", the screen won't freeze but there is no 3D acceleration. When booting without "nomodeset" and without the module "nouveau" active, the screen won't freeze. In all cases, I can switch to the text console with Ctrl+Alt+F1 before the screen freezes. The results are the same with a mainline kernel.

Status in “linux” package in Ubuntu: Incomplete Bug description: During a booting process, there should a "kubuntu" logo with 5 blinking dots since I am using Kubuntu. But it shows a black screen instead after loading the kernel and before Xorg started. Disabling modeset can get back the boot splash but lost accelerated 3D. After Xorg loaded, it shows a normal composited desktop with full hardware acceleration. But pressing Ctrl+Alt+F1 will hide the mouse cursor and cause the screen to freeze. Pressing Ctrl+Alt+7 can switch back to Xorg. It is also true for live DVD or a fully updated(as of today) system. WORKAROUND: I get back the text console by doing the following: 1) Blacklist nouveau 2) Rename "/lib/modules/2.6.38-8-generic/kernel/drivers/gpu/drm/nouveau/nouveau.ko" to something else. 3) sudo update-initramfs -k all -u 4) sudo update-grub2 5) Reboot.
