** Description changed: 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.
