I did a fresh install of F28 (which I then promptly updated) on a Dell Precision M6700 laptop (old laptop, equipped with a Amd Fire Pro M6000 2Gb graphics card). I was finally happy to sport a open source supported card in my system but for some reason at every boot plymouth doesn't show itself but instead three dots appear. I even tried to remove it (by dnf) and reinstall it, rebooting, but still same behaviour.

Didn't have this happening on a Dell Latitude laptop of the same age with a Nvidia card.

Any chance I can fix it?

The laptop BIOS is the latest one (april 2018!) and there's no hybrid graphics or other settings to play with. The machine has 2 drives, system is installed in the one in the secondary compartment (/dev/sdb, a SSD), the other one in the primary compartment (/dev/sda, a HD) is just a big empty (just created) ext4 partition.

Thanks :)

The three dots you are seeing is actually plymouth using an alternative theme called "text". From the file /usr/share/doc/plymouth/README:

It is designed to work on systems with DRM modesetting drivers. The idea
is that early on in the boot process the native mode for the computer is
set, plymouth uses that mode, and that mode stays throughout the entire
boot process up to and after X starts. Ideally, the goal is to get rid
of all flicker during startup.

For systems that don't have DRM mode settings drivers, plymouth falls
back to text mode (it can also use a legacy /dev/fb interface).

DRM is defined as Direct Rendering Manager and your display adapter or the device driver for it may not support it. During boot there is no Xorg to provide graphics support, so the graphics support must be provided by the device driver for your display adapter.

Thanks! But plymouth Ubuntu logo shows up correctly on Ubuntu's 18.04/18.10 installations...

Same problem here, fresh install F28 on a new laptop also (Lenovo ThinkPad T470s)

i tried changing the theme to something else but the same three dots appear, switched back to Charge and still the same.


I am now using "tribar" and no more three dots as it shows a loading progress, however, since I have full disk encryption using LUKS, the password theme doesn't show up and still broken.

sudo plymouth-set-default-theme tribar -R

So it seems like a compatibility issue between plymouth and its themes!

try this and see if it helps. the plymouth themes may have issues if the 16 bit linux loader runs. the commands shown here remove the 16 from the load commands. This works for legacy bios mbr systems, if you boot efi, check the grub manual for the location of efi files on your system.

sudo cp -a /etc/grub.d/10_linux /root/etc-grub2-10_linux.original
sudo sed -i -e 's/sixteenbit="16"/sixteenbit=""/' /etc/grub.d/10_linux
sudo grub2-mkconfig -o /boot/grub2/grub.cfg

I would test this first. After boot, when the boot menu appears, hit the "e" key. Then edit the linux16 and initrd16 words. Then hit Ctrl-X to start booting. If it doesn't work, the old configuration is still intact.
