I cannot code in C nor do I profess to be anywhere close to scripting as you 
guys, but I think a better solution to fixing the submenu issue would be from 
source code.

Is it at all possible to simply load the menuentry items under the submenu 
command without having to reload the entire theme?  If it can be done, wouldn't 
it prevent the flicker seen as the theme reloads?

Problem is that it's possible to do something like:
submenu "xyz" {
   theme=...
}
And thus change the theme for submenu.

While at it, could you also please fix the keyboard lag that results when a gfx 
theme is used.  This is an issue with many users of gfx themes .

Thank you.

The only way a regular user can workaround this at the moment is to reload the 
theme after the submenu menuentry item is selected.

In Ubuntu's (about the only distro that uses the submenu command at this time) 
use of the submenu in 10_linux:

 if [ "$list" ]&&   ! $in_submenu; then
   in_submenu=:
 fi

A regular user must patch 10_linux thus:

 if [ "$list" ]&&   ! $in_submenu; then
   echo "submenu \"Previous Linux versions\" --class submenu {"
   if [ "x$GRUB_THEME" != x ]&&   [ -f "$GRUB_THEME" ] \
   &&   is_path_readable_by_grub "$GRUB_THEME"; then
   prepare_grub_to_access_device `${grub_probe} --target=device 
"$GRUB_THEME"`
   cat<<   EOF
set theme=(\$root)`make_system_path_relative_to_its_root $GRUB_THEME`
EOF
   fi
   in_submenu=:
 fi

What a perfect example of overengineering just to compensate for missing
"export theme". I've fixed it in trunk

to reload the theme and have a themed submenu.

Will this be fixed in the 2.00 release?

And ryuo, I assume that phcoder's recent request there for testing of

Search for images within sub-directories of the theme's directory.

2012-02-23 Thread Towheed Mohammed

The following components:
1. image
2. progress_bar, and

3. circular_progress

have the 'theme_dir' property.  A theme designer can use this property to place 
image files within sub-directories of the theme's directory.  However, 
00_header searches for images only in the theme's directory:


    if [ x"`echo "$themedir"/*.jpg`" != x"$themedir/*.jpg" ] || [ x"`echo 
"$themedir"/*.jpeg`" != x"$themedir/*.jpeg" ]; then
        cat << EOF
    insmod jpeg
    EOF
     fi
     if [ x"`echo "$themedir"/*.png`" != x"$themedir/*.png" ]; then
        cat << EOF
    insmod png
    EOF
     fi
     if [ x"`echo "$themedir"/*.tga`" != x"$themedir/*.tga" ]; then
        cat << EOF
    insmod tga
    EOF
     fi

Please modify 00_header so that it will search for image files within 
sub-directories of the theme's directory.


Thank you.

grub-mount (ubuntu) hangs with hfs+ partition

2012-02-23 Thread Kees Bakker


Hi,

In Ubuntu (and Debian I guess) there is a grub-mount command.
It's added to grub with branch_fuse.patch, and in that file it mentions
http://lists.gnu.org/archive/html/grub-devel/2011-01/msg00056.html

I have a MacPro system with Ubuntu installed and some HFS+
partitions. Everytime I do a kernel update (and update-grub)
it hangs when a grub-mount command is used on one of the HFS+
partitions.

The grub-mount command does not hang on all my HFS+ partitions.
But the fact that it hangs on one of them makes it very annoying.

I've tried to debug this problem, but I am not making any progress.
The program hangs in a while(1) loop at line 657 in grub-core/fs/hfsplus.c

BTW. I've also tried to contact Macro Gerards (the contributor of the HFS+
code), but I didn't get a reply from him.
