Ho ho ho, Thx, Thx a lot, it did work like a charm now.

It really need to be lowercase.

grubby --update-kernel /boot/vmlinuz-$(uname -r) --args="cma=256M"

: ) I'm so happy. Thx Thx Man. 

Sorry but I didn't make the bridge between the desktop image parameters and the kodi use (dammm :~ )

When I tryed to use same parameters in the /boot/efi/config.txt, and they didn't work and I didn't figure out it need to be in the kernel command line.

If possible, add the solution in the forum do fedora, and mention it need to use it with kodi

the cma may need to be lowercase
