Ubuntu 9.04 ("Jaunty Jackalope") is the current
release, and I've installed it on all of my machines. It's a
much better release than 8.10 ("Intrepid Ibex"), although a few
minor issues remain. This one's a keeper, folks.
This is an article
about booting multiple operating systems
with GRUB (the GRand Unified Bootloader). The article
discusses GRUB in general terms, and focuses on its relation to
the master boot record (MBR), partition table, and partition
layout on disk. A list of reference links is provided at the
end. It was written to summarize what I learned during an
exchange of messages on the mailing list of
the Milwaukee Linux Users
Group (MLUG), of which I'm a member. If you're in the
Milwaukee area, feel free to come to one of our meetings;
everyone is welcome!
Here are some instructions for creating
a GRUB boot
floppy for your system in case of emergency.
If you can't print from Java programs in Ubuntu, try
opening the printer setup panel (System / Administration /
Printing), and for each printer, go to the Job Options tab and
change the orientation from "Automatic rotation" to "Portrait
(no rotation)". Note: This is no longer necessary
in Ubuntu 9.04.
In Ubuntu (using GNOME with Compiz), if you add more
desktops but there are no entries for them in the keyboard
shortcut menu (Preferences / Keyboard Shortcuts), you can
manually edit this file and add them:
~/.gconf/apps/metacity/global_keybindings/%gconf.xml
(Note that this file may not exist until you have made some
changes to the default shortcuts, so make sure to change one
first so you have something to copy and paste. You may also need
to log out and back in again for the new shortcuts to take
effect.) Note: This bug still exists in Ubuntu
9.04.
If GRUB is giving you the message "Error 28: Selected
item cannot fit into memory" when you try to load memtest on a
newer machine, it's not his fault. For an excellent description
of the problem,
see this
message attached to Debian bug
report 319837. The
solution is to write memtest directly to a floppy (i.e. not to a
filesystem on the floppy) and boot from there. If you're too
modern to have a floppy drive, you're on your own! Here's the
simple command that will do it:
cat /boot/memtest.bin > /dev/fd0
