Grub2/Grub2 Themes Usage Issues

[Stephen Morris]

Hi,
     I have activated the usage of the Starfield theme for grub2 in 
Fedora 17 and I am having issues with it.

     1). Scrolling through the list of entries in the menu at boot time 
is horribly slow. Every time I scroll with the arrow keys the screen 
flashes black and it takes several seconds for the next/previous entry 
to be highlighted.
     2). I have just upgraded from from an Nvidia Geforce 9800 GT to an 
Nvidia Geforce GTX 650 (this is a PCI-E 3 card plugged into a PCI-E 2 
slot) and now I can see the graphics for the theme being drawn on the 
screen as I watch, whereas with the 9800 the screen draw was 
instantaneous. The issue highlighted in point 1) occurs independently of 
the graphics card in terms of the same thing happens with both graphics 
cards.
     3). When I do an upgrade that upgrades the kernel the upgrade 
process tries to update the grub2 config and mbr but is unable to 
because /sbin/grubby fails with an access denied error even though I am 
effectively running in root mode via sudo (implemented via the wheel 
group). I have also tried this after switching to root mode via su but 
that fails with the same error.
     4). Because of the error highlighted in point 3, when upgrading the 
kernel, I have to manual run a grub2-mkconfig and grub2-install to 
update grub and this process rebuilds the Starfield's Theme.txt file 
back to the defaults from the manual customization I have done from 
white/grey bold text. The black/black bold text does not work for me on 
the Starfield background.

     My system is an Asus Sabertooth 990FX R2.0 motherboard, AMD FX 4 
GHz 8 core cpu, Geforce GTX 650 2 GB graphics card, 16 GB memory, 256 GB 
SSD (this has Win 8 and the boot partitions for Fedora 17 and Ubuntu 
12.10 installed on it) and 2 2 TB Seagate hard disks, so from my 
perspective computing power is not an issue.

     What is the best way to rectify these issues?

regards,
Steve
