Bug Description
When secure boot is enabled on an EFI system, it is not possible to display background images in TGA format because the tga module is not pre-loaded by the signed grubx64.efi binary and it is not possible to insmod the module in a secure boot environment.
The jpeg and png modules are pre-loaded and it is possible to display background images in those formats.
Since the backgrounds in the grub2-splashimages package are distributed as TGA images I believe this should be considered a bug.
