I installed Startup Manager in Ubuntu 9.04 (Jaunty) to try to hide the boot text that is displayed on screen. I've played with numerous combinations of options as described in this guide. Particularly these:
Show bootloader menu. When selected the bootloader menu displays available options such as kernels, recovery modes, memtest86+, and other operating systems, if installed. If this option is not selected, no bootloader menu will be displayed during boot. The default or saved OS selection will be used.
Show boot splash. Enables the splash screen viewed during the boot process.
Show text during boot.
Manage bootloader themes. Add or remove an installed bootloader theme.
Usplash theme.

However, nothing makes the boot messages go away, starting with "Reading files need for boot" and then listing a whole bunch of information such as setting up the firewall etc, which drivers are loaded etc.
Is there any other approach I could use?
dmesgoutput to see if the system tried unsuccessfuly to initialize the graphical boot? – nagul Sep 20 '09 at 19:59
