Plymouth is a bootsplash used to show splash screens during system boot and shutdown.
Specific kernel options must be altered in order to get Plymouth working properly. Use the genkernel --menuconfig all command (or equivalent) in order to modify the kernel configuration.
It is highly advised to disable the Linux bootup logo. On some systems having the bootup logo displayed seems to cause problems.
Device Drivers ---> Graphics Support ---> [ ] Bootup logo --->
Be sure to enable kernel modesetting (KMS) for the system's respective graphics card.
KMS for Intel cards
Device Drivers ---> Graphics Support ---> <*> Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) ---> <*> Intel 8xx/9xx/G3x/G4x/HD Graphics [*] Enable modesetting on intel by default
If this is the user's first time modifying settings for on-board Intel GPUs the Intel article should be referenced for additional configuration.
KMS for Nvidia cards (Nouveau drivers)
Device Drivers ---> Graphics support ---> <*> Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) ---> <*> Nouveau (nVidia) cards
If this is the user's first time changing settings for the NVIDIA graphics card using the nouveau driver be sure to reference the nouveau article for additional information.
KMS for Nvidia cards (official drivers)
To use the official Nvidia drivers see the wiki's official Nvidia-drivers article.
So far the results of using official Nvidia-drivers are untested with Plymouth.
KMS for Radeon cards
Device Drivers ---> [*] Staging drivers ---> [*] Enable modesetting on radeon by default
If this is the user's first time setting up a Radeon graphics card be sure to reference the radeon article for further information.

||Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces|
||Provides abstraction to the DRM drivers (intel, nouveau and vmwgfx at this moment)|
||Add support for x11-libs/gtk+ (The GIMP Toolkit)|
||Adds support for printing text on splash screen and text prompts, e.g. for password|
||!!internal use only!! Security Enhanced Linux support, this must be set by the selinux profile or breakage will occur|
||Enable this if /bin and /usr/bin are separate directories|
||Build static versions of dynamic libraries as well|
||Enable virtual/udev integration (device discovery, power and storage device support, etc)|
The sys-boot/plymouth package can be installed by running:
emerge --ask sys-boot/plymouth
/etc/plymouth/plymouthd.conf - the sole configuration file for Plymouth. It can be left untouched. Selecting theme is described in further section.
Bootsplashes are loaded by initramfs so they need to be included in it.
Although there are plans to do so, at this point in time, genkernel cannot create an initramfs with a Plymouth theme included. Therefore, in order to proceed, either use dracut or manually build initramfs.
Dracut (sys-kernel/dracut) is an alternative initramfs generator created by the Fedora development team. Fun fact: Plymouth and Dracut are both cities in Massachusetts. Though this is speculation, the creators of these programs might have taken this into consideration.
Dracut should enable Plymouth automatically if it is installed. See the Dracut installation instructions.
Some themes such as kde-plasma/breeze-plymouth require certain files to be included in the initramfs such as label plugins and fonts. These currently have to be added manually using
install_items. See this section on the Dracut page for customizing the image, and the example mkinitcpio hook for which files to add.
Manual initramfs creation
When creating a manual initramfs, for example using Custom Initramfs, it is possible to bundle Plymouth.
udev USE flag for Plymouth (it will not display anything until udev is properly initialized). Otherwise udev will need to be added to the initramfs as well.
echo "sys-boot/plymouth -udev" >> /etc/portage/package.use
emerge --ask sys-boot/plymouth
Then, populate the initramfs with the plymouth files and theme. While it may be done manually, the better way is utilizing /usr/libexec/plymouth/plymouth-populate-initrd. It will deliver all the binaries, config and themes needed (only the theme that is enabled, so do not forget to re-execute when changing theme).
The script will copy all the files to selected directory.
Add this code snippet to the initramfs generation script, just before the initramfs packing:
.... # populate plymouth if available if [ -x /usr/libexec/plymouth/plymouth-populate-initrd ] then /usr/libexec/plymouth/plymouth-populate-initrd -t $INITRAM_DIR fi ....
Finally, update the actual init script in initramfs:
.... # Plymouth needs /dev/pts mounted mount -t devtmpfs none /dev mkdir /dev/pts mount -t devpts /dev/pts /dev/pts .... # early in the process start plymouthd and show splash if [[ -x /usr/sbin/plymouthd -a -x /usr/bin/plymouth ]] then mkdir -p /run/plymouth /usr/sbin/plymouthd --attach-to-session --pid-file /run/plymouth/pid --mode=boot /usr/bin/plymouth show-splash fi ....
Plymouth automatically registers itself with systemd to show splash screens during shutdown and restart. No additional configuration is required.
There is a plugin for Plymouth that extends a single line version of OpenRC's status to the framebuffer. It can be installed via:
emerge --ask sys-boot/plymouth-openrc-plugin
No additional configuration for the plugin is necessary, it should be operational next time Plymouth is run. To remove this functionality simply uninstall the plugin.
Additionally, make sure that the RC is non-interactive. Edit the /etc/rc.conf file:
When using GRUB, an update to GRUB's configuration file must be made in order to enable the splash screen during early boot. Append the options
quiet splash to the GRUB_CMDLINE_LINUX_DEFAULT variable. It may be desirable to adjust the resolution in the GRUB_GFXMODE variable to match the desired resolution for the monitor, and set GRUB_GFXPAYLOAD_LINUX to "keep" in order to preserve the graphics mode during the entire boot.
This all can be performed by modifying the /etc/default/grub configuration file:
GRUB_CMDLINE_LINUX_DEFAULT='quiet splash' GRUB_GFXMODE=1366x768x24 GRUB_GFXPAYLOAD_LINUX=keep
After emerging Plymouth, a number of themes will be pulled in automatically, however more Plymouth themes can be downloaded from the web and installed manually. Extract the downloaded themes to the Plymouth theme directory: /usr/share/plymouth/themes
Make sure each new theme is contained in its own folder (just like the default themes that are installed) or they will not be detected by Plymouth.
Once the themes have been extracted, verify successful extraction by requesting Plymouth generate a list of all available themes. Do this using the plymouth-set-default-theme command:
Assuming the solar theme is desired as the system's theme, run:
The solar theme will be used for the rest of the examples in this article. Simply replace
solaranywhere it appears with one of the other themes listed when using the plymouth-set-default-theme command, to set a different theme.
It is possible to create themes for Plymouth. See the Theme creation article for more information.
Regenerate manually, or if dracut is used, execute the dracut command to regenerate it:
As long as the configuration has been performed properly, this will pack the selected Plymouth theme into the initramfs.
Finally, regenerate GRUB config to use the initramfs and apply the GRUB graphical settings:
grub-mkconfig -o /boot/grub/grub.cfg
For Plymouth to work as intended, the proper GRUB video modules must also be loaded. Generally the correct video modules are loaded by default on Gentoo, so inserting additional ones is not usually needed. If frame buffer or video problems are being experienced with GRUB, be sure to investigate missing modules as a possible culprit.
According to the README file distributed with Plymouth, boot messages are dumped to /var/log/boot.log after the root filesystem has been mounted read-write.
