Thank you Matt :)
I wish to be able to configure everything. Individual names, sub-menus,
no splash-videos, screen resolution for the messages etc. and the way I
do it, by editing grub.cfg is the easiest way and perhaps only way too.
The temporarily grub.cfg for my new Ubuntu install isn't ok until now.
It might be that I just need to command out something, e.g. 'set
gfxpayload=$linux_gfx_mode' and 'quiet splash vt.handoff=7', but perhaps
I need to edit much more.
Once I edited update-grub2 to save 'grub.cfg.date_and_time' instead of
'grub.cfg'. But this isn't reliable, regarding to upgrades, it's better
to have a backup of grub.cfg. Btw. it's also annoying that when
installing upgrades, that update-grub2 is launched several times, taking
minutes to detect imaginary Linux installs or existing kernels, that
should be excluded from the menu.
At the moment grub.cfg isn't important. I'm struggling with the
non-working mouse wheel for Maverick and Natty, a very, very slow motion
GNOME when switching between Evolution and Firefox by the GNOME panel
for Natty only, sometimes it's fast, but often very slow. The fact that
the theme isn't stable, sometimes I get the WM only and need to log out
and log in, the fact that having XFCE parallel installed will cause
issues for GNOME, the fact that my old audio card isn't working
regarding to the fact that PA is enabled, ... all in all I tend to
switch the distro, the fact that 32-apps that without issues work on
e.g. 64-bit Suse, even don't work on a 32-bit Ubuntu etc. ... there are
issues, issues, issues that aren't caused by Linux, the hardware, me,
just by Ubuntu.
It's a pity, because excepted of the missing kernel-rt, Ubuntu Studio
audio is very good. Those developers and packagers do very good jobs.
I guess on Monday I'll get my new audio card, so today and tomorrow I'll
set up a MIDI/ audio work station. Regarding to my needs I need to build
Jack from svn, to get no MIDI jitter and other things, so I'm not happy
about needlessly complicated stuff.
FWIW, my temporarily, experimental, unfinished grub.cfg is attached.
Bye,
Ralf
