Asked by Spiralnebel

hi

would like to know how to change the resolution for the cryptsetup password boot prompt

You mean GRUB_GFXMODE? You need to use vbeinfo instead vga.
You need to edit /etc/default/grub
https://help.ubuntu.com/community/Grub2#/etc/default/grub%20%28file%29

because changes in grub.cfg wont survive the next update.

The resolution do not fix 100% cause no i have a black vertical stripe on the right side
but now i know the procedure and will play around till it fits.

Thanks a lot for your help!

The fix i used let the screen look nearly like before the installation of the Nvidia driver
but anyway there's still a bug regarding Plymouth in combination with that driver so
in my mind this case isn't realy fixed. It would be nice to have a exactly the same look
of the Plymouth screen as before!
