It works for me without any of that in /etc/grub/default, though I used
to have it there.

$ cat /etc/default/grub
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
#GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="SYSFONT=latarcyrheb-sun16 LANG=en_US.UTF-8 KEYTABLE=uneaf CONSOLEBLANK=60"

Here is a boot stanza from my /boot/grub2/grub.cfg, generated with
grub2-mkconfig -o grub.cfg
Looks a lot like the Debian stanza that works.

### BEGIN /etc/grub.d/10_linux ###
menuentry 'Fedora' --class fedora --class gnu-linux --class gnu --class os --unrestricted $menuentry_id_option 'gnulinux-simple-f908bebb-66db-48db-a429-fe716bf67592' {
        load_video
        set gfxpayload=keep
        insmod gzio
        insmod part_gpt
        insmod ext2
        set root='hd0,gpt1'
        if [ x$feature_platform_search_hint = xy ]; then
          search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt1 --hint-efi=hd0,gpt1 --hint-baremetal=ahci0,gpt1 --hint='hd0,gpt1'  d56ad7bb-4913-45b7-a56e-562e6275b995
        else
          search --no-floppy --fs-uuid --set=root d56ad7bb-4913-45b7-a56e-562e6275b995
        fi
        linux16 /vmlinuz-4.2.0-0.rc0.git1.1.20150627.fc21.x86_64 root=UUID=f908bebb-66db-48db-a429-fe716bf67592 ro SYSFONT=latarcyrheb-sun16 LANG=en_US.UTF-8 KEYTABLE=uneaf CONSOLEBLANK=60 
        initrd16 /custom-4.2.0-0.rc0.git1.1.20150627.fc21.x86_64.img
}

Incidentally, though the consoleblank=60 is supposed to set the timeout
on virtual consoles to 60 minutes, it doesn't work.  I still have to
set it manually after logging in.
