Short, flickering horizontal lines in GTK apps
by Ian Pilcher
https://drive.google.com/file/d/0B9ZGcvLVEr8kd0swQmNNc1ZSblE/view?usp=sha...
Is anyone else seeing anything like the effect in the linked video?
I'm seeing this occasionally since upgrading my ThinkPad T430s with
Intel graphics (Core i7-3520M) to Fedora 21. I am running KDE with
desktop effects enabled, and thus far I have only seen this in GTK
applications (Firefox, Thunderbird, and LibreOffice).

KVM/QEMU remote connection
by Glenn Holmer
I'm trying to connect to another machine using virt-manager (File/Add
Connection). I select QEMU/KVM as hypervisor, "connect to remote host",
method SSH, and a username and hostname on the remote machine. The
result is always that I get prompted for my passphrase, but then see
"authentication failed: no agent is available to authenticate". I get
this going from either machine to the other.
Virtualization is set up OK because I can run virtual machines on both
VM hosts. SSH is set up OK, I can ssh with public key in both directions
both as myself and as root. I tried "setenforce 0" on both machines to
see if SELinux was blocking it, but the result was the same.
What am I missing?

NETDEV WATCHDOG: internal(r8152): transmit queue 0 timed out
by sean darcy
I've got F20 on an old laptop I'm using as a router. The external
interface uses the RJ45 port. The internal uses a USB ethernet adapter.
Every 2-3 weeks, the internal USB adapter fails. I can fix it by just
moving it to the other USB port. In another 2-3 weeks, it will fail
again, and I move it back to the original USB port, and so on.
No problems with the external RJ45 interface.
The logs aren't very helpful:

This looks like a USB problem. Is there a way to get usb (or
NetworkManager) to reinitialize the driver when this happens?

With newer updates to Fedora 20 the wakeup timer does not work...
by dwoody1
I have Mythtv installed. I setup a wakeup timer that worked in Fedora 19
so the computer would boot up in time to record a show and then shutdown
until the next recording was scheduled. But in Fedora 20, with the
inclusion of halt into systemd, the wakeup timer does not work.
In Fedora 19 the timer needed to be reset in the halt init script after
the hwclock was updated.
Mythtv has a page describing how to setup the timer but it has not been
updated to reflect the systemd requirements.
I assume that the shutdown in systemd needs to be modified but I am
unsure how.
I have searched for wakeup, systemd, mythtv, hwclock and others but have
not found what I need to change.
Thanks for your help,
David

GNU Backgammon now works
by Paul Cartwright
Afer the latest kernel update:
uname -a
Linux localhost.localdomain 3.17.8-300.fc21.x86_64 #1 SMP Thu Jan 8
23:32:49 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
I started and was actually able to play a complete game of GNU
Backgammon! before this ( since I installed it a few months back) every
time I started backgammon, it would paint the window with the board
and..... CRASH, no matter what I did or tried.

Installing new header files
by Ashoordin
A friend of mine has installed the Fedora 21 on my pc. I am new to Linux
OS's. I am trying to learn it in order to write, compile and run C++ codes.
Since I need to calculate some hard and long double integrations in my
project, I am told to install the nr3 (numerical recipes 3th edition) which
includes all the header files needed to run the programs. However, I don't
know the actual procedure to download and install those files in my system
so that each time they are needed, the compiler can find them with no
problem. Your help is greatly appreciated.
Sincerely,
