Instal cryptsetup has no influence at all. I have found a partial solution at /usr/share/doc/plytmouth : readme. This is because the driver that permits high-color graphics tends to
cause issues with suspend and resume, and we opted to prefer that
For nVidia and ATI users, the default "nouveau" and "radeon"
drivers are Kernel Mode Setting enabled, but do not always
provide 3D capability at the current time. By switching to
using the restricted/non-free nvidia-glx or fglrx drivers,
you will gain 3D capability at the loss of a high-color
You can however chose to enable high-color (and resolution) console
if you find it doesn't affect suspend/resume for you, or you don't
use that feature.
There are various methods of doing this, the most robust is the
following four steps:
Append video=vesafb to the GRUB_CMDLINE_LINUX_DEFAULT in
echo FRAMEBUFFER=y | sudo tee /etc/initramfs-tools/conf.d/splash
sudo update-initramfs -u
At the moment i have splash screen in low resolution at startup (always better than black screen) - and normal splash at logout.
