** Description changed: Ubuntu 11.10 and Ubuntu 12.04 have an issue where neither the boot messages nor Plymouth are shown. This is due to GRUB2 not having a font to load (unicode.pf2) and therefore update-grub doesn't generate needed sections in the grub.cfg file. Here's a diff of Debian's and Ubuntu's grub.cfg (on UEFI), both on a completely minimal base system with GUI (to make sure no package interferes): http://diffchecker.com/IN68Vue You can see how Debian loads the unicode.pf2 font and also runs the "load_video" function, which loads the video modules needed for EFI. While it's for a different error, the Arch Linux Wiki also explains this: https://wiki.archlinux.org/index.php/GRUB2#Correct_GRUB2_No_Suitable_Mode_Found_Error The problem can also be worked around by adding the following in grub.cfg: load_video set gfxpayload=auto EDIT: It seems that the linux_gfx_mode is being set to 'text,' which does NOT work with UEFI, as it doesn't have a native text mode (I think). + + EDIT2: After copying /usr/share/grub/unicode.pf2 to /boot/grub and + regenerating the grub.cfg file, here's the diff: + http://diffchecker.com/qu771dU However, for some reason, the workaround + above is still needed :( I'm not sure what's going on here.
