OT: Creating a livecd with efi support using Fedora
by Michael D. Setzer II
Currently, I have a project that I build on Fedora systems that uses syslinux
to boot from CD or USB. I've only found stuff that mentions Ubuntu, Arch,
and some other distro on building EFI option, but even then it is talking about
patched versions. Lots of info on installing it to a hard disk, but I haven't
found any links that show how to add it to a boot CD?
Project currently using syslinux 5.10, but switching to 6.x also works fine,
have just been waiting for 6.03 to be releases since there are some issues
with 6.x that 6.03 is suppose to fully resolve. Have asked on the syslinux list,
but the responses point to other distro builds, and I would prefer to keep it
using Fedora.
Project can also boot fine from the grub system, but that only helps if
someone is already using a linux distro, and my project is disk imaging and
many people that use it have windows only systems.
Thanks.

frequent kernel oops -- how do I report it?
by SternData
I'm getting frequent kernel oops in F20, but my kernel is "tainted" so
abrpt won't report it. /proc/sys/kernel/tainted has a value of "512".
What do I do?
It seems to be a windowing problem related to Chrome, but also occurs if
I'm doing stuff with bluetooth. Here's the latest:

yumex won't skip checking for updates
by Robert Moskowitz
In preferences I have unchecked 'autocheck for updates', but everytime I
start yumex, it checks for updates. Then I have to click on 'Available'
and wait again as it does its think before I get the list of all apps so
I can search for whatever I am looking for. Quite a rather unpleasant
experience.
So how do I set yumex to skip checking for updates and just go to what
is available?

Mirroring issue
by Mike Chambers
Hey all,
Got an issue I want to get thoughts/opinions on.
I currently mirror Fedora releases, updates, rawhide, etc...But on the
releases, that is the problem. Fedora has a few directories to mirror
and not sure which scenario to use.
1 - I currently mirror the *whole kit and kaboodle* directory (it has
everything in other words), that way if/when I install a package that is
or uses a package from the Fedora main repository, I can get it. And
then if for some reason I need to reinstall Fedora (20 in this case), I
use the http option as my connection is pretty fast and doesn't take
forever to install. Why I do it that way is because the *everything*
directory doesn't have an installable tree to use.
2 - I have mirrored the installable tree directory (basically the
release, as you would get it on dvd), so can do reinstalls or whatever
from Fedora with no issues. But if you install a package from somewhere
and it calls for a Fedora package not in the mirror, then you are stuck.
So I guess using this scenario, would have to change the repo from yum
to use the *everything* tree from http (since the connection is fast
anyway), but takes away reason for mirroring in first place.
3 - I guess I have the room (spare disk used for mirroring and such away
from system) to just mirror both and not have to use internet at all, at
least from Fedora perspective?
Any thoughts/suggestions/issues, are more than welcome.

Problems after replacing an ati videocard by a nvidia card (F20, both 512 MB memory)
by Joachim Backes
Problem description: replacing my ati video card (DVI) by a nvidia card
(DVI too) generates problems: almost unreadable (flickering) screen
during boot after some boot progress (even without rhgb), no gdm login
screen.
The primary F20 system was installed with the ati card.
Running "dracut --force" was no solution.
After investigating a little bit I saw that the grub boot-parameter
"video=1280x1024-24" was the culprit: replacing "video=1280x1024-24" by
"video=DVI-D:1280x1024-24".
Both the ati card and the nvidia card have a DVI connector.
So I can't explain this weird effect. Anybody has an explanation?
Kind regards

Camera mounting
by jarmo
[Solved]
I had my booting system into multi-user. Started XFCE from command
line..
Now somehow XFCE couldn't do mounting without root privileges.
I changed boot direct into graphical.target, so now I get medias
mounted without root privileges..
Sorry for noise, should check better my system and what I had done..
Till next time being as stupid :))

Well even Linus T. is not happy with some of the problems with systemd.
In this case he is pissed at another systemd dev who exhibits the same
attitudes towards 'outsiders':
"Key, I'm f*cking tired of the fact that you don't fix problems in the
code *you* write, so that the kernel then has to work around the
problems you cause.
Greg - just for your information, I will *not* be merging any code from
Kay into the kernel until this constant pattern is fixed.
This has been going on for *years*, and doesn't seem to be getting any
better. This is relevant to you because I have seen you talk about the
kdbus patches, and this is a heads-up that you need to keep them
separate from other work. Let distributions merge it as they need to and
maybe we can merge it once it has been proven to be stable by whatever
distro that was willing to play games with the developers.
But I'm not willing to merge something where the maintainer is known to
not care about bugs and regressions and then forces people in other
projects to fix their project. Because I am *not* willing to take
patches from people who don't clean up after their problems, and don't
admit that it's their problem to fix.
Kay - one more time: you caused the problem, you need to fix it. None of
this "I can do whatever I want, others have to clean up after me" crap.

X preview repo?
by Tom Horsley
Just wondering if there is anything like the virt preview repo
for the latest bits of X11, mesa, etc? (I suspect the answer
is "no", but I figured it couldn't hurt to ask :-).
I ask because the 4K monitor I just got working stopped
working again following an update that dragged in some bits
of mesa and perhaps other things.
I switched to ubuntu on the system with this monitor, and
ubuntu does have a "ppa" repo "xorg-edgers" for everything
bleeding edge in X. I was able to get the monitor working
on ubuntu (possibly it will even survive some updates
since the repo includes all the dependent bits, not just
the nvidia driver).
Perhaps I'll try rawhide, but things seem to break
a lot in rawhide :-).

You cannot 'eliminate' it, but you can circumvent it from getting in the
way. I use
yum -y erase xine-lib-pulseaudio alsa-plugins-pulseaudio
It is the latter which is the important one for using alsa.

DNF Doesn't Appear to Have --skip-broken
by Stephen Morris
Hi,
I have an issue whereby I can't do a sudo dnf upgrade to
upgrade the versions of Mysql from Oracle's Mysql repository because one
of the other repositories has a package upgrade that won't be applied
because it has a dependency on a gdm version that as yet doesn't exist,
and, dnf appears to not have support for yum's --skip-broken parameter.
Does dnf have support for this functionality so that sudo dnf upgrade
will upgrade the packages I want to and ignore the packages with
dependency issues?
regards,
Steve
