A workaround on my system is to include the video driver (in my case i915) in the initramfs.
sudo nano /etc/initramfs-tools/modules sudo nano update-initramfs -u ensure kernel command line includes 'quiet splash' sudo update-grub Reboot lshw -c video will confirm that driver i915 is configured. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2091753 Title: Plymouth fails with kernel 6.8.0-50 Status in linux package in Ubuntu: Confirmed Bug description: Plymouth fails to fully boot with this kernel when asking for encryption password for local partition. The system freezes and can be recovered in rescue mode. Previous kernels accepted the password and continued to X as expected. Remove 'splash' from GRUB_CMDLINE_LINUX_DEFAULT="quiet" prevents plymouth from loading and booting continues to X after password is entered in when booting pauses and asks for the password in the terminal. This behaviour is true on laptops running Linux Mint (Wilma) and Ubuntu KDE 24.04 with encrypted partitions. On devices without encrypted partitions 'quiet splash' is included on the kernel command line and booting proceeds as expected.
