Fedora 21 Software choices
by Max Pyziur
Greetings,
I popped the F21 "Workstation Live" disc into one of my machines. It came
up w/ Gnome 3 w/ one of the choices being "Software."
There, you could browse all of the different application sofware
choices by different categories and sub-categories (Audio, Video,
Education, Development, etc).
I briefly looked at the Fedora Project page hoping to find something
similar: where F21 software offerings are shown. Is there a webpage or two
where these might be listed?
Thanks.

How to increase maximum user cpu usage allowed on a multi core system?
by stan
I'm running Fedora 21 with a custom compiled kernel,
3.19.0-1.20150211.fc21.x86_64.
I have a multi core system with 6 cores. All are recognized by the
kernel.
But, when I run a compile job with -j6, in order to allow all six cores
to be used, it limits the total amount of usage to 100% of a *single*
core. So, it might use all six cores, but the sum of the percentages
on those six cores is always around 100% of one core. This is from
htop output.
On large compilations, like the kernel or firefox, even using 4 cores
could drastically reduce compile time.
I've looked at /etc/security/limits.conf, but it doesn't seem to have a
setting for this. I've also looked at the /proc system to see if there
is a kernel variable, though that seems unlikely, with no luck. Online
searching found ways to limit the amount that a single job can get, but
not how to set this for a user. There must be a configuration variable
somewhere that is limiting the amount of total cpu a user can use. But
I can't find it.
Can anyone help?

SELinux is preventing mkdir from write access on the directory root.
by Lawrence E Graves
SELinux is preventing mkdir from write access on the directory root.
***** Plugin catchall (100. confidence) suggests **************************
If you believe that mkdir should be allowed write access on the root
directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep mkdir /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

is there a bt mouse that auto-connects on linux?
by Neal Becker
After buying a logitech bt mouse, and finding it won't auto-connect of F21
(kde), I'm planning to return that and try something else. Is there another
that is known to work? Something smallish for a notebook.

Which scanning application for colour-profiled scanner?
by Tim Waugh
Hi,
I've used gnome-color-manager to generate an ICC profile for my
scanner using an IT8.7/2 target I ordered. The next step, obviously,
is to scan something.
I was trying to work out how to set up xsane to use the profile I'd
generated, but I'm having trouble working it out. I also saw a note in
the gnome-color-manager commit log that seemed to be saying it
wouldn't work anyway ("too broken").
Is there a scanning application that will automatically ask colord for
the profile to use, and use it?
Alternatively, is there a recommended scanning application for
profiled devices?
Thanks,
Tim.

Constant DHCPREQUEST
by Gary Stainburn
Hi folks,
While looking at my network I've spotted that my laptop is constantly sending
DHCPREQUEST. Everything appears to be working fine, both on my laptop and
elsewhere apart from this. One other client, a Win7 PC appears to have the
same problem, but everything else on the network seems fine and refreshes
only infrequently.
Any ideas?
/var/log/messages on my laptop:

Issue with GOG native games and opengl?
by Bruno Wolff III
When running Icewind Dale's start up script I get the following:
Running Icewind Dale Enhanced Edition
libGL error: unable to load driver: nouveau_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: nouveau
libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swrast
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 154 (GLX)
Minor opcode of failed request: 3 (X_GLXCreateContext)
Value in failed request: 0x0
Serial number of failed request: 84
Current serial number in output stream: 85
They only officially support Ubuntu LTS, so I can't get official support
from GOG.
Is there a way to work around the above? (Other than running the Windows
version under Wine.) The game works in current f21, but not rawhide. I
suspect this is due to mesa or nouveau versions rather than a bug.

Re: F21 systemd log flood - how to stop
by Andy Hairston
After even more Google searching, I found the command
systemd-analyze set-log-level warn
Running this as root, I got:
Failed to issue method call: Access denied
Strangely, I can run it with 'notice' instead of 'warn', and it silently
completes - probably meaning it's already set to notice.
Why does this produce an 'access denied' message even when run as root?

mdadm or LVM for software raid?
by Tom Horsley
I see mdadm is one cryptic way to setup a software raid
and I saw some note somewhere that says LVM also supports
software raid1. Any reason one is better than the other
(or does LVM not actually do raid and I misread something)?
My BIOS also has some sort of Intel raid helper hardware
thing, but I can't imagine there would be a good reason
to use it since all the data would become nearly inaccessible
trash if I have to replace the motherboard :-).
