Because I wanted to see all the messages during booting. But I have the problem that the most time the monitor is black. Only at the end of the booting process I can see some text.
I have now restored the default configurtaion of grub and rebooted the system. I saw the message "mountall: plymouth command failed" and there was no splash screen.
In grub I have changed some settings all the time:
GRUB_CMDLINE_ LINUX_DEFAULT= "" _LINUX= 1680x1050- 24
GRUB_GFXPAYLOAD
