Thanks for the heads up. I found the destructions, now could you
please explain what they mean? I am totally unfamiliar with xorg.conf
, or could you point me in the right direction to be able to learn.
This is definitely a feature I don't want to lose.

I agree. I use this all of the time. It is hard to accidentally press three keys
at once, so I don't buy the reasons for implementing it.

You actually need to type: sudo dontzap --disable
in a terminal window to bring back ctrl-alt-backspace. Note: this only applies
to 9.04, Jaunty Jackalope.

Thanks so much THAT I understand. Can't wait to try it.

after installing dontzap that is. its not installed by default

`sudo apt-get install dontzap` in a terminal or get it through synaptic

I did not have to do this step. Don'tzap was already installed on my system
without my having to do anything. If you do it, it won't do any harm, though. It
will just tell you that it is already installed. Better to have peace of mind
than to wonder if it will work when you need it.

True enough. odd that dontzap was not installed here but was on yours.

Dontzap is the app that prevents ctrl-alt-backspace. This would mean that it is
installed by default, but for some reason it was not installed on yours. Perhaps
you ran an earlier version that did not have it and for some reason it was never
installed. It does not really matter in any case as you seem to know what you
are doing and can either install it or not as you choose.

There is some discussion that dontzap does not work on some computers. See:
http://ubuntuforums.org/showthread.php?t=249899 and
https://wiki.ubuntu.com/X/Config/DontZap

I am sure that we have not heard the end of this discussion. I am a big defender
of Ubuntu/ Canonical because I respect what they do, but this is wrong headed
IMO. I have never heard of anyone simultaneously pressing three keys that
require two hands by mistake. It takes caution to an extreme bordering on
paranoia. Is this signs of more to come to protect users from their own
stupidity or just an aberration? I hope that it is just the latter.

I had the *dontzap.py which I presumed stole the ability to restart X
but had to install the package to run the command from terminal.

emacs call for a lot of ctrl-alt commands but i doubt anyone using that
would mistake that keystroke.

I would like to see the old default behaviour returned for update
notification as well. though I suppose waiting a week for notification
might save some from broken updates. Just another thing to change
every fresh install.

OK installed jaunty this afternoon. Tried the
control-alt-backspace- didn't work.
then did the sudo dontzap --disable and was told dontzap was
not installed so I installed it
then tried the disable command again. nothing happens it still
wont work.. Any other ideas?

You might to reboot to get it to work or at least reload X. Failing this you can
try to edit xorg.conf manually.

Just add the following lines to /etc/X11/xorg.conf:


Section ServerFlags
Option DontZap false
EndSection
There is some discussion in other forums about having to take additional steps.
Let us know how you make out.

I rebooted several times before asking for help :) Can you explain
reload X. So sorry, I am very new to Linux and still trying to learn the
language. Now editing xorg.conf I finally understand however the
information you told me to add did not make it thru the email as you can
see below.

Section ServerFlags
Option DontZap false

Can you please translate this ?
Which forum is this being discussed. I was unable to find any mention of it.

We seem to have two different scenarios and I am curious as to why. I went the
upgrade route rather than the fresh installation route and I have dontzap
installed by default and did the dontzap --disable command and I can
ctrl-alt-backspace to shutdown X.. I've tried it and it works.

When I said restart X, I meant log out and back in which ends one X session and
starts an new one. The xorg.conf file is the Linux equivalent of the Windows
registry. Important settings for graphics, mouse, etc are stored there. It is
just a text file.

The section to add was:

Section ServerFlags
Option DontZap false
EndSection

The spacing is single space after section, option and between "DontZap" and
"false"
EndSection is all one word as is "ServerFlags"

I have not tried this but you can if you want. Apparently
ALT GR (this is the RIGHT ALT key) + SYSRQ (Shares PrintScreen on my keyboard) +
K
will have the same effect as Ctrl-Alt-backspace

I really appreciate all your help, unfortunately I still cannot
read your instructions. It comes thru on this end as total gibberish
with unknown characters and even a strange icon which I would be at a
loss as to how to duplicate. I've tried at least 50 different fonts to
see if it could be decoded, but nothing has worked so far.
On the brighter side, the altnerate keys you gave me DID work !!!!
Voila, now if I can just remember that combination LOL. Thanks so much.

Yes two different scenarios. I totally reformatted all my discs and did
a fresh Manual install so my /home would be separate partition. Since
then have discovered my alternate HD is also bad, so now there are 2
drives on their way back to Seagate. I suspect that most of my other
problems are related to that bad HD. It wasn't dead, but it wouldn't
hold any data. Refused to let me add a folder even tho it says I was
owner with full permissions. Tried reformatting, but it wouldn't hold
and unable to do a filesystem check on it- always failed suspect bad
sectors- it was a recent replacement for another HD that died some time
ago- didn't last even a month.

Section: "ServerFlags"
Option: "DontZap" "false"
EndSection

Will store this one away
for future reference since it seems that the alternate keystrokes
are working.

Is there a command to display your current version # (vintage, date, release#,
or build#)? For those of us who may not know which one we are using.

Will the Update Manager automatically give you the option to upgrade (e.g., from
8.10 [or earlier] to 9.04) when it becomes available?

To find the version (from terminal): cat /etc/lsb-release

You can also find out from Firefox by going to Help, About Mozilla Firefox. :)

Another useful thing to know is the kernel version. Use (from terminal): uname
-r

You can upgrade from the previous version. You cannot skip versions, so must
upgrade to the previous version before upgrading to the latest. So the upgrade
path from Hardy (8.04) would be to Intrepid (8.10), then Jaunty (9.04). The
exception to this is from one LTS to the next which would be from Dapper 6.06 to
Hardy 8.04 to something that begins with L 10.04.

Yes the upgrade manager will give you the option to upgrade. At the top it will
say there is a new version with an upgrade button.

I'll file this is a safe place so I don't ask again next time.

I installed the upgrades. Nice graphics, nice Gnome. I like it. I will try for
Linux Mint also on the other hard disk.

I upgraded from 8.10 on my mini 9 last nite - 3 hours - flawlessly
Less than 10 minutes to upgrade my HP Compaq Laptop from 8.10 -
flawless, at least so far for both. Love it. cuzzin dick
