Is it too late to get a backtrace if you didn't already have gdb and the

Since both bug-buddy and kcrash use it, gdb is already present on
nearly every installed system.


Having a 'QA Tools' package group is a pretty great idea. But first..
we need some tools.

No, as long as you have the right pieces of the core dump (or, y'know,
the whole thing). You can use the BuildIDs embedded in the core dump
to gather the exact binaries (and associated debuginfo) used in the
crash, and retrace the backtrace from there.


That's part of what the server side of Apport does - takes incomplete
crash dumps and retraces them. Then you can generate a hash of the
trace[1] and compare that to other known crash-hashes to get automatic
dup finding.


Actually, if possible you'd want to generate a hash of the *un-
retraced* dump too, and have the reporter app check the database of
known/frequently reported crashes *before* submitting. Then the user
gets:


"CRASHYAPP has just crashed. This is a known problem and is being
worked on by DISTRO developers. You can follow the progress of this
work here: BZLINK"


Wouldn't that be nice?

-w

[1] We'd want a special filter for the trace and/or a specialized hash
function to make sure that crash dumps that are *very* similar end up
with hashes that are similar or identical.

That is something new to me. I have upgraded Hardy with meta packages to
the LTSP Server, MythTV and Studio. Everything just works, as we use to

Is this page disinformation?

Absolutely! Essentially Ubuntu Studio is made up of meta packages for
Ubuntu. Its a great model.. very modular, flexible, scalable, etc.

Its so easy to remove and add packages after install of regular
Ubuntu. I would personally be happy to see U Studio NOT focus on a
install cd at all! It has more potential to introduce new bugs or fall
behind in development. For those who have limited bandwidth, U studio
could distribute DVD's full of all packages that make up the Studio
(Audio, Video, Graphics). When you finish your install you could pop
the dvd in, add it to sources.list, and install the pertinent content.
Synaptic is easy enough to use; could be confusing to many... Perhaps
a fancy little program could come pre-installed that would guide the
users through this?

..my 2sense.

But what about the realtime kernel etc? I am still a relative newbie when it comes to all of this, but I thought that one of the things that really sets studio apart is the realtime kernel. If you were using the standard version of ubuntu, and simply installed all of the studio packages, wouldn't you still be running on the standard kernel? *Personally, I prefer the DVD installers, because I find them clear, straight forward and simple to use.*

Just like the U Studio meta packages, the realtime (rt) kernel is
available to all Ubuntu users. You can install/un-install it anytime
with apt (synaptic).

Thanks. I had assumed (d'oh!) that I could wait and read the elog if I
ever decided to install the new grub to my boot partition. I'm not so
happy with the boot partition being mounted and screwed with by the
ebuild, especially given I was using a grub from Fedora, not Gentoo.
Now I've got DONT_MOUNT_BOOT="yes" in make.conf, so I should never have
this kind of problem again.

Once I booted a livecd, running the setup command within grub fixed
the problem. Then once I booted Gentoo, I did it again, to get
whatever goodness is in this latest revision.

Even if I had a floppy drive, I'm not sure portage wouldn't find the
floppy and overwrite it.

I usually have a livecd or two in my bag, but of course not when I most
need one.

I'm cc-ing the bug report you have opened. Anybody who answers this bug
should also read the thread that has followed the original message, as
it contains many other useful details.

Do you use use anti-aliasing (aa)?

I've used mlterm for quite some time without the problems you mentioned.
The problems seem, at first glance, as those of missing glyphs
("characters") in the font(s) you use.

I use mutt as well. I don't see any special settings I need.
(I do need to use bidiv to properly see messages whose charset is marked
as "ISO-8859-8-i", I've had problems aliasing that to cp1255. But no
problems with UTF-8).

In fact, I'm now using a default installation of Lenny (with Hebrew
selected as the language). I can see none of the problems mentioned
here.

I normally use mutt under screen from a remote Etch (this is the one
from which I write now). But I also tested this with a local mutt from
my Lenny installation. It seems to be a bit slower but displays the text
just as well.

BTW: the default "anti-aliased" font was horribly wide. I disabled
anti-aliasing. And then I noticed that the font I got had bad
pixelization issues (at the default size of 16). Changing the size to 14
made the problem go away. But Hebrew was displayed just as well with the
original anti-aliased font.

The fonts I have installed:

culmus
gsfonts
ttf-unfonts
ttf-unfonts-core
ttf-unfonts-extra
xfonts-100dpi
xfonts-75dpi
xfonts-baekmuk
xfonts-base
xfonts-encodings
xfonts-scalable
xfonts-utils

(That's Culmus and packages that contain "fonts" in their name. Maybe
there are others).
