Bugzilla Bug 242736

When using GRUB as boot manager and wanting to reboot to a specific entry of
the boot menu, KDM displays the available options quite fine but fails to store
the selected option. The recommended way is to call /sbin/grub-set-default to
store the selected option as default for the next boot. KDM doesn't do this.
The KDE 3.5 behaved the same way. The Gentoo ebuild for kde-base/kde applied a
patch to fix this (see e.g. bug bug #153566). There is a upstream bug for KDE,
but it is still not fixed (bug #63800 of KDE).

Reproducible: Always

Steps to Reproduce:
1. Activate KDE logout menu.
2. Select one of the 'non standard default' GRUB entries.
3. Let computer reboot.

Actual Results:  
Reboots into the 'standard default' GRUB entry, not the one selected.

Expected Results:  
Reboot to the selected 'non standard default' GRUB entry.

A patch very similar to the one used in KDE 3.5 series can be applied for 4.1.2
too. We need the diff and a change to the current ebuild for KDM.

A diff-file to make the needed changes to KDM's backend/bootman.c

Same problem here with KDE 4.1.3 and grub 0.97. The proposed patch solved the
issue. 

Please update to 4.3.1 and see whether still applies. Also please try attached
patch.

Trying 4.3.2 with and without patch. All does not work.
"grub-set-default 4" also does not boot in the right kernel for me.

Can someone confirm this with grub-0.97-r9?

Both the grub-set-default command and 4.3.1 ebuild work fine for me.
Did you set up your grub menu to work with the saved default?
You would need to include "default saved" at the top of the file (see also the
added attachment for a simple example grub menu).

The bug seems also to be fixed in KDE svn now (see
http://websvn.kde.org/?revision=1030993&view=revision).

OK, bugzilla hates me. Can't attach the example for some reason. As it is
rather short, added it below.


default saved

splashimage=(hd0,4)/grub/splash.xpm.gz

title Gentoo - KMS
    kernel (hd0,4)/kernel1 root=/dev/hda8 desktop CONSOLE=/dev/tty1
    # switch back to have the first entry as default
    savedefault 0
