Kernel boot options 'nosplash text' not fully respected

[Trond Melen]

When booting the linux kernel with the two options 'nosplash' and 'text', I think there should be no graphical splash screens displayed, only text. Still, in Ubuntu 10.04 Lucid Lynx there is a splash screen both after boot and before shutdown (with the package 'ubuntu-desktop' installed, the splash screen is redish with 5 dots; with 'xubuntu-desktop' its black&white with the word 'xubuntu'). These splash screens may cause problems if there is a framebuffer issue with the system.

Regards,
Trond Melen

Hi Trond,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

New bug report added, still seems to be an issue against the latest kernel.

After wasting two hours rebooting my machine to figure out why nosplash is not recognized, I realized that it's probably looking for the string "splash" in /proc/cmdline.

Indeed, "nosplash" was the cause of the splash screen, and removing it entirely disables the splash screen... I remember with usplash, removing splash was not always enough, so this is confusing.

Also, while doing this, I found out how to disable the graphical splash. For those people who like a splash screen but do not want the framebuffer issues, there is a text-only splash screen available:

echo FRAMEBUFFER=n | sudo tee /etc/initramfs-tools/conf.d/splash
sudo apt-get remove plymouth-theme-kubuntu-logo

Also--shouldn't this bug be filed under "plymouth" and not "linux"?
