System-wide profiles don't seem to find debug information since Fedora 15
by Clemens Eisserer
Hi,
I have been using Sysprof for quite some time, but with Fedora 15 it
stopped working properly.
Where it presented pretty stack-traces including timings in Fedora 14
when debuginfo-packages where installed, it just presents very cryptic
and less informative information since F15 - usually this was only the
case when debuginfo-packages were not installed.
Today I tried oprofile instead, but got the same results - I just get
results with binary granularity:

Linpsk audio -
by Bob Goodwin
Does anyone have experience getting Linpsk to work in F-15. I
can see audio in the Pulse Audio Volume Control GUI but it
doesn't seem to reach the Linpsk input. I am not aware of any
sound problems with this computer so it has to be something I
have misconfigured but I'm not sure where to look next.
Suggestions from anyone who has done this would be appreciated.

HELP!!! System messed up!
by John Aldrich
A little while ago I inadvertently killed power to my F15 box. Now I'm
unable to get a better screen size than 1024X768 (previous was
1280x1024) as well I'm having problems with my keyboard and mouse. The
keyboard will suddenly not work any more (i.e. I can't type) and the
mouse will somewhat work -- I can open a new console, etc, but I can't
make that the "active" window.
I have already tried using the nvidia-xconfig, but that screws it up
worse. (yes, I have an nVidia graphics chipset -- driver is noveau
according to /proc/modules)
If I have an xorg.conf file it REALLY hoses the system and I don't get
ANY graphics whatsoever and I have to rely on SSH-ing into the box to
init 3, delete the xorg.conf and restart x, at which time it's
somewhat normal.
Anyone got any ideas what the heck I did and how to fix it?

OT: need bash help
by Mike Wright
Hi all,
I'm trying to write a bash script and having problems.
If I execute this:
ps x | grep mongod | wc -l
it returns a value.
OTOH, if I execute this:
LINES = ps x | grep mongod | wc -l
it returns "command not found".
How does one assign the output of a command to an environment variable?
TIA,
Mike Wright

Re: restricted shell
by Hugh Caley
Not precisely what you are requesting, but the "sudo" command could be
used to allow your admin root access to certain commands only.
See "man sudo" and "man visudo". The /etc/sudoers file has examples of
this sort of functionality, but should only be edited using the visudo
utility.

You can look into "chroot"ing, where the other person has a different
root directory, and all the sub-directories, and you copy the commands
that they're allowed to use into their directory tree.
Of course, to do this properly, you also need to make sure that they
can't use a compiler, else they can create their own commands.

Would it not be appropriate for Fedora to pay some kind of tribute to the

Re: imac on lan, printing to f14: network host '192.168.2.8' is busy, will retry in 30 seconds

On my f14, I did 'system-config-firewall'
and checked
Network Printing Server (IPP)
now I get a different response when trying to print from the iMac
initially it acts like it is starting, but then goes into 'paused' state
I can click on resume printing, it again seems to start,
but immediately again goes into 'paused', and I can't break out of this cycle.
I do have the 'sharing' and 'internet' boxes checked on the admin page.

I bought an adapter to connect the headset (3.5mm jacks) to USB. Works.
