The presence of text on shutdown is determined by whether the kernel console had any errors to display before then. For most machines the answer will be no, but for some hardware there will be messages there already (see also bug 1870041).
After that, Plymouth will try to switch to graphics mode again using the DRM backend. But that depends on the driver still being usable while it's also being unloaded for shutdown. Also Plymouth may refuse to display if it estimates the display time is too short and shutdown (or boot) is already completed. So the existence of console messages is the real bug, which is not a Plymouth bug. If you also find the shutdown time is so long that Plymouth really should have been displaying something then it might also be the issue with no usable graphics driver being available to new processes like plymouthd. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2160567 Title: Plymouth splash does not appear on shutdown/reboot (works correctly on boot) — TPM-backed FDE, dual GPU (Intel + AMD) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/2160567/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
