GNOME3 and Modifying command-line arguments
by Khemara Lyn
Dear All,
Normally, I could go "Applications -> System Tools -> Terminal" and the
app "gnome-terminal" would start and po up a new terminal window with a
command prompt.
The default terminal size is not optimal for me and i would like to
adjust it a bit. With previous version (GNOME2), I could just do a
right-click on the icon and edit "terminal command" to something like this:
"gnome-terminal -geometry 100x35"
But now in GNOME3, I can't find out how to do it any more?
When we browse the program/app menu, we see their icons. When we click
an icon, the corresponding app will run (with default command set by
GNOME). How can we modify the command or its arguments from the default
(as in the example above for gnome-terminal)?
Any help please?
Thanks & regards,
Khem

How do I inspect a dconf database file?
by Göran Uddeborg
If I have understood things correctly, the file ~/.config/dconf/user
contains all personal settings I have changed from the default. Does
anyone know a way to list the content of this file in a human readable
format?
In the old GConf system, I figured out I could list all local settings
in this way:
gconftool-2 --direct --config-source=xml:readonly:$HOME/.gconf --recursive-list /
Is there any way to do something similar in the new Gsettings/Dconf
environment?

Support for Intel H77
by Geoffrey Leach
I'm considering the purchase of a Puget Systems Echo I HDPC. It
features an Intel DH77DF (Intel H77 MiniITX) MB.
Not the point. Can anyone say (or point me to a source) if the H77
graphics are supported (have the appropriate driver) under Fedora 16.
Thanks.

Eclipse WTP and Fedora
by Fernando Lozano
Hi,
Fedora has for a long time included Eclipse, Tomcat and (bits of)
Geronimo and Glassfish. And now F17 provides JBoss AS.
But why Fedora Eclipse doesn't includes WST? Is there anything that
prevents Fedora to provide the Eclipse IDE for Java EE developers as
part of the distro? Am I supposed to download a fresh new Eclipse from
Eclipse.org for Java EE development, instead of using Fedora Eclipse? Or
is that just a question of manpower to package and test so many plugins
and their dependencies?
Most users will have trouble finding how to enable Eclipse.org update
sites to get those missing features. :-(
(By the way, who should I contact to volunteer to write those docs and
put the on Fedora web site / wiki?)

VirtualBox cannot start on F17
by Paul Smith
Dear All,
I have just installed F17 (clean installation), and when I start my
virtual machine through VirtualBox, I get the following error:
Failed to open a session for the virtual machine WindowsXP.
Failed to open/create the internal network
'HostInterfaceNetworking-eth0' (VERR_INTNET_FLT_IF_NOT_FOUND).
Additional information:
# rpm -q VirtualBox-4.1
VirtualBox-4.1-4.1.16_78094_fedora17-1.x86_64
#
Any ideas?
Thanks in advance,

Re: Filesystem format for external hard disk
by J.Witvliet@mindef.nl
Hi,
You might consider using rsnapshot from a different machine to collect your backup's.
And once in a while, make a copy of _that_ data on an external disk, and put that in a different building (parents, children, friends, shurestore). So if dissaster strikes hard, you still have your data.

That's a good point. I guess now would be a good time to mention that a
volume snapshot != backup (see below), however, I've heard of snapshots
sometimes being used to create a "still" or "point-in-time" copy of the
system, which itself is backed up, since backups can take a considerable
amount of time.

Labels are okay, but I dislike them because they are abitrary. If labels
are used, then don't used a label like "backups" because it's too likely
to have a naming collision. Use a label like "red-rover red-rover" which
is less likely to have collisions.
As far as using an external drive is concerned, for my backups, I opted
not to do this, because when my house burns or gets blown away by a
tornado, or is robbed (in which case the burgler is likely to take
everything attached to the computer, too) that on-site backup isn't
going to help very much; but the question was just about formatting a
drive.

Issue with bash completion
by Suvayu Ali
Hi,
After the upgrade from Fedora 16 to Fedora 17, completion for any of my
wrapper functions (for standard tools) are not working. To give an
example, I have a wrapper around find called find_ext. I want it to
complete just like GNU find so I define the following completion:
complete -F _find find_ext
However this does not work. Completion is working for find itself, just
not my wrapper function. I see that the completion function `_find` is
not even defined in my shell (there is no output for `declare -f
_find`).
This is even more surprising since I see that _find is defined in
/usr/share/bash-completion/completions/find. However I could not find
anything in /usr/share/bash-completion/bash_completion that actually
sources the files in /usr/share/bash-completion/completions/ (although
it does for /etc/bash_completion.d/).
Has something changed drastically? How do I make my wrappers complete
using standard completion functions?
Thanks in advance for any ideas.
PS: When I use a custom completion function (with none of the standard
ones inside) it works as expected.

F17 install failure on JBoss-as-7.1.1-2.fc17.noarch
by William Henry
Both upgrade F16, preupgrade to 17 went fine. Install failed on JBoss-as package.
Have to exit the installer. :-( retried a few times and several more packages were installed but then it hits JBoss-as. Wish I could just skip.
I wonder will I have the option to go back to 16 and remove offending JBoss and try again. (?) it doesnt seem so as it hangs on f16 boot.
Any suggestions welcome. Perhaps someone can fix the JBoss package. It is complaining about the media possibly being corrupted.

BackupPC problems since upgrade to F17
by George Avrunin
I used preupgrade to move from F16 to F17. The installation
hung up (installing Steel Bank Common Lisp; this
seems to be a problem other people have had, e.g.,
http://forums.fedoraforum.org/showthread.php?t=280318) but when I
restarted, it completed and seems to have been successful. I did
have to add "namespace inbox {inbox = yes}" to my dovecot.conf to let
claws-mail get my e-mail, but otherwise things seem to mostly be working
fine.
But I'm having some problems with BackupPC. I use this machine to
backup itself and a couple of other Fedora boxes (still at F16 and
F15) to an external USB disk that I mount under /scratch and then use
a symbolic link to /var/lib/BackupPC. There were a few minor selinux
issues with contexts, which I seem to have fixed up with a couple of
restorecons.
However, the web interface doesn't seem to be able to get information
about the backups on the hosts. So, for instance, it shows whether
any backups are running and some of the status information (like the
size of the pool file system), but it claims that none of the hosts
have any backups and it says the pool contains 0 files. However, I was able
to use the web interface to initiate a full backup of one host and all the log
information indicates that completed successfully (with 847583 files,
117689557865 bytes, 0 xferErrs). Moreover, although (after a restorecon
suggested by sealert), I can read the logs (e.g., /var/log/BackupPC/LOG and
the older ones) from the web interface, when I go to the page for a specific
host and try to read the LOG file for this host (by clicking in the panel in
the upper left), it tells me "Can't open log file". The backuppc user can
read the file, however. (The overall LOG file is in /var/log/BackupPC; the
one for the particular host is in /var/lib/BackupPC/pc/<hostname>/.)
I'm not seeing any audit entries when this happens (and I've tried running
with selinux set to permissive and it doesn't make any difference). The file
ownership and permissions (up to /var/lib/BackupPC) seem ok to me. And
backups completed successfully the morning of the day I did the upgrade
(which I checked before doing the upgrade ;-) ).
The only things I'm seeing in the httpd logs are a lot of "Use of qw(...) as
parentheses is deprecated ...", which apparently is due to the BackupPC perl
code not having been updated to correspond to recent enough Perl version.
But from what I've been able to find, (a) this was happening with F16, and
(b) it's just a warning and shouldn't have anything to do with this
problem.
Does anyone have any suggestions about what else to look at to sort this out?
Given that it seems to have resulted from the upgrade to F17, I thought I'd
ask here first, before trying the BackupPC list, but I checked that and
don't see any reports of problems with F17.
Thanks,
George
