Yes MOST of it is hideable!
Interestingly, in 8.04, having it hidden is the DEFAULT and many of us go and remove the line that hides it.
If you mess up here, taint my fault! Because the change is made in your bootloader!
Then ADD the words Quiet and Splash behind the letters ro in the boot linuz command line.
gksu gedit /boot/grub/menu.lst
Wait a minute, I see you are brand new posting here. Let me add a file designed for just the opposite as it will be more informative. Now remember, this file shows the exact opposite, how to REMOVE the words quiet and splash, you want to ADD the words quiet and splash if they are not there.
If they are there, you have a different problem or a different Ubuntu Version than 8.04.1 the LTS version.
Boot Text Not Showing During Boot-up? Easy fix!
Ubuntu 8.04 Hardy Heron
From a Noob for fellow Noobs!
I don't know about the rest of you, but I HATE looking at a blank screen and NOT knowing what's going on during boot-up.
If you would like to see just what's going on during boot-up, here is a quick and easy way to make it happen!
Left Click on Applications, from Accessories select Terminal.
In Terminal type gksu gedit /boot/grub/menu.lst (if you are using grub that is).
If you are multi-booting several Distro's select the first Ubuntu entry, which is the normal boot. There will also be a Recovery boot, normally under it, and possibly a memtest under that.
In the Normal Boot listing you will see a line that reads 'kernel' /boot/vmlinuz at the end of this line, after the 'ro' you will find the words 'quiet' and 'splash'.
See OPTION below line that reads SAVE and Exit.
Simply remove these two words, leaving everything else intact.
Don't worry about the word 'quiet' under initrd in the left column.
SAVE and Exit.
OPTION: As a precaution, you may want to Comment out the existing line by placing a pound sign and a space (# ) in front of the existing line, then copy and paste it below the original. Uncomment the new line by removing the pound sign and make the changes to this new pasted line. You can always comment out the new line and uncomment the original line and be right back where you were before making any changes.
When you reboot, you should see all the boot-up text just as in other Distro's!
To Undo, just follow the above directions to put back the two words you removed.
