NVIDIA X Server Settings thinks I'm not running NVIDIA driver, but I do.
by Oliver Ruebenacker
Hello,
I installed the nvidia driver via yum from RPMFusion and lsmod confirms
that nvidia is loaded and nouveau is not.
But when I run the NVIDIA X Server Settings (KDE on F20), it claims I do
not appear to be running the NVIDIA driver and should configure it by
running nvidia-xconfig as root and restarting the X server.
nvidia-xconfig creates an new /etc/X11/xorg.conf file (see below).
Previously, no /etc/X11/xorg.conf file existed.
Then, when I try to re-start X, it will not start saying no screens
found, until I remove the xorg.conf file and then everything is back to
normal, including NVIDIA X Server Settings saying that I do not appear to
be running the NVIDIA driver.
Did some googling and followed some advice to set the BusID in xorg.conf,
but did not help.
Any ideas? Thanks!
Best,
Oliver

Fedora still doesn't sign its repo data?
by Joonas Lehtonen
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512
Hi,
over five years ago vulnerabilities in Fedora's (and others) package
managers [1] have been presented at USENIX.
And even though yum supports repo_gpgcheck since 2008 [2]
Fedora still does not make use of it to protect the repo metadata.
Are there specific reasons why Fedora still does not sign its repo
metadata to prevent metadata manipulation attacks (i.e. "hiding" updates)?
The LWN article from 2009 somehow hinted that it was about to be
enabled in Fedora 11? [1]
I filed a bug against fedora-release (covering the missing
repo_gpgcheck in fedora.repo) [3].
Which component would I file the missing repomd.xml.asc (on fedora's
repositories) against?
thanks,
Joonas

OT: bash help
by Mike Wright
Hi all,
I'm trying to write a simple script that if provided an argument, uses
that, or if nothing is provided, uses a predefined string.
if [ -n $# ]
then
WORDS=$1
else
WORDS="these are some words"
fi
echo $WORDS;
The second case is always comes back "".
But if I write
WORDS='these are some words'
echo $WORDS
I get the assigned string.
Why doesn't the assignment work when inside an if/then? How do I make
it work? What's the difference between the case where the assignment is
inside the if/then and outside the if/then?
TIA,
Mike Wright

Where can I find SELinux knowledge
by Robert Moskowitz
The setup is armv7 (Allwinner A20 based Cubieboard)
F19 remix kernel
Redsleeve EL6
SELinux is coming up disabled, and I can't figure out what is needed.
And no help on the Redsleeve list, as its heritage is armv5 and the
kernels for them do not seem to have SElinux support, so no experience
with enabling it.
Of course there is the 'age' mismatch of F19 kernel and EL6, don't know
if that is an issue.
Centos7 for arm is aways off, so for now production is RSEL.
And F21 is also aways off and F20 is a remix; I AM working with it for
some cases.

Mesa-10.2.5 was released - while Fedora still ships 10.1 :/
by Clemens Eisserer
Hi,
First of all thanks for Fedora, I am a (most-time) happy user since
Fedora 2 and it is really great to see how all the improvements
accumulated over time.
Especially with the accelerated release cycle of Mesa, it would be
great if Fedora could keep up in the same manner as it does with the
kernel.
Mesa 10.1 is effectively dead with 10.2 beeing considered "old, stable
and boring" now.
So the descision is not between shipping stable/proven versions vs.
bleeding edge, but rather shipping outdated stuff vs maintained stable
versions ;)
Thanks & best regards, Clemens

ibus-daemon & gnome-shell: high cpu usage...
by Georgios Petasis
Hi all,
Gnome (for some reason) takes all my cpu power under fedora 20 64 bit.
And if I kill ibus-deamon, the session still runs. But I cannot kill
gnome-shell.
When ever I start a computation, gnome-shell kicks in, and takes *all*
cpu. For example, when running (a single threaded) Tcl/Tk program:
Tasks: 291 total, 3 running, 288 sleeping, 0 stopped, 0 zombie
%Cpu(s): 52.0 us, 1.7 sy, 0.0 ni, 45.9 id, 0.1 wa, 0.1 hi, 0.0 si,
0.0 st
KiB Mem: 32832636 total, 31349172 used, 1483464 free, 573716 buffers
KiB Swap: 61439996 total, 4036 used, 61435960 free, 23766116 cached
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+
COMMAND
11321 petasis 20 0 1974296 401952 69288 S 306.9 1.2 477:55.92
gnome-shell
13662 petasis 20 0 347500 120636 13388 R 93.4 0.4 9:07.78 wish
1551 petasis 20 0 310492 108392 27968 R 22.6 0.3 63:30.66 Xvnc
My application shows a load of 93% (one of the cores), Xvnc 23% (the
wish application updates some dialogs),
but gnome-shell eats 300% of my cpu (3 whole cores?). Is this normal?
I think it is very high...

George

A tool for Ext? partitions.
by JD
Need a tool that can scan an entire drive (which has no partition table
- as it got accidentally clobbered by dd'ing 512 bytes into it), and
determine start and end of ext(2/3/4) partitions.
I need this so that I can restore each ext? partition to a separate HD.
So far I have found a windows based tool from EaseUS.com , but is not
open source and
is not free.
Thanx,
JD

Re: centos/fedora install without gui!
by bruce
--mke2fs pre-computes the ratio of number of inodes to total number of
available block in the chosen partition
are you implying/saying that there can only be a single inode count
for a given patition size??
in my case, I'm going to have a large number of small files (2-5K) and
I might have millions in my test.
