I went back and followed your suggestion for editing the blacklist file, just in case the method I used to re-enable the blacklist on radeonfb was cause.
sudo rm /etc/modprobe.d/50-blacklist.conf
sudo zypper in -f sysconfig
The above three commands ran without obvious error .
Is plymouth running now or not?"
Well, plymouth runs after accepting the top (default) menu item in the Grub2 menu.
Normally, if I recall correctly, there is a mostly black graphical screen (gecko on branch), which I think is what is called the bootsplash.
Normally, about 2 to 3 seconds into boot a message appears with a box, requesting the password for my encrypted back-up drive that mounts during boot.
Normally, I enter the password and enter, a couple more seconds go by and the KDE Login Greeter appears.
Now, when I hit enter to select the default menu item in the Grub2 menu, I see some messaging from Grub about initial ram disk mounting, etc (Normal to here), then the display goes black briefly and the I get a message from the display saying no input, auto shutdown (of the display) will occur soon.
Watching the hdd activity light on the desktop looks normal, and 2 to 3 seconds after the screen shutdown message I hear a faint ‘thump’ from my speakers, similar to when I un-mute audio. This same thump would normally occur when the bootsplash was properly displayed. When I hear the thump, I enter my crypto disk password and enter, a couple seconds later the screen comes back to life with the KDE login Greeter displayed.
So plymouth is running, but it’s display is not.
It seems as if the plymouth graphics driver might be having an issue, or perhaps the bootsplash file is corrupt?
The contents of /etc/sysconfig/bootsplash are the defaults:
## Path: System/Boot
## Description: selects bootsplash graphics theme
## Type: string
## Default: ""
## Command: /sbin/mkinitrd
# Bootsplash theme. Should be based in /etc/bootsplash/themes/.
Suggestions obviously welcome.
