Comment 16 for bug 761830

I installed from an alternate installer ISO (ubuntu-11.04-beta2-alternate-i386.iso), and chose the server option, so it was installed as a commandline system. After installation, I installed X and various X clients, but not gdm -- for now I'm still booting into the console login prompt (except there wasn't a prompt, just a blank screen/blinking cursor).

After reading this bug I've commented out the "for word in $GRUB_CMDLINE_LINUX_DEFAULT; do" clause in /etc/grub.d/10_linux, and also changed GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub to "noplymouth" instead of "quiet splash", and now my boot is working great and I get the expected login prompt.
