xclock
by Amadeus W.M.
Is there a replacement for xclock? It seems to have gone out of existence
after a recent update or upgrade. I'm currently running F25 + MATE.
Thanks!

Multiboot and EFI
by Patrick Dupre
Hello,
If I understand correctly, the beauty of GPT/EFI is that I can select
the boot disk.
However, how can I manage mulibooting on a single disk ?
grub2 ?

F26 Run KDE under wayland on nouveau driver
by Barry Scott
I'm running KDE plasma under X11 at the moment and would like
switch to wayland.
First is this supported? If so where is the config that I need to change to
start up in the wayland world and not the Xorg world?

probably off topic audio question
by Tom Horsley
Randomly, if I play a youtube video in google chrome,
I'll get a pop-pop-pop... audio background noise at a rate
of about 1 every half second. If I close the chrome
app, the pop-pop-pop... keeps going for about 30 seconds
after chrome goes away.
Anyone else ever had this happen? Anyone have any idea
what it is?
This is on fedora 24, google-chrome-stable, all updates
applied. The audio output is nvidia HDMI using the rpmfusion
binary drivers. It isn't very frequent, and I can come back
to the same video later and it will often play fine,
so it isn't even reproducible. Nothing shows up in any
logs that I can find or in dmesg.

[slightly OT] writing "POSIX-compatible" scripts, and script
analysis tools?
by rpjday@crashcourse.ca
(admittedly not an actual "fedora" topic but i'm sure i'll get some
good advice here.)
i'm currently perusing someone else's collection of shell scripts,
and looking to add more, and want to clarify once and for all the
meaning of writing (and verifying) the "POSIX-ness" of shell scripts,
and what tools i can use to detect "bashisms" (or lack of POSIX-ness)
in scripts.
first, can i verify that trying to keep my scripts as POSIX-compatible
as possible is a good thing? i've always assumed that, just curious as
to what others think, and how much effort they put into adhering to
the POSIX standard (thereby giving up all those cool bash extensions).
next, if i want to enforce POSIX-ness, is it just a matter of using
#!/bin/sh --posix
actually, i already know it's not that simple, since i'm sure i've
read that even adding that "--posix" option still leaves some
non-POSIX features active; i'll re-read the docs to verify that.
finally, pointers to shell analysis utilities? WRT fedora packages,
i've already found:
* devscripts-checkbashisms
* ShellCheck
and i suspect there are others.
so, thoughts? and any pointers to online coverage of this stuff?
thank you kindly.

cannot use Pitivi because of obscure missing library/plugin
by M. Fioretti
Greetings,
I urgently need to clip and save a few scenes from some mp4 files.
Nothing more.
Only machine I can do this right now is a fedora 25 x86_64 box.
When I launch PiTiVi from the command line, it starts, but it says:
Missing soft dependency:
- libav not found on the system
-> additional multimedia codecs through the GStreamer Libav library
But I haven't been able to figure out WHICH package/repository is
supposed to provide that libav library. Dnf search returns so many
packages of gstreamer plugins that I fear to make things worse by
installing them at random.
If I ignore that warning and I try to import the mp4 files in PiTiVi, it
complains like this:
Problem: gst-core-error-quark
Extra information: gst-core-error-quark: Your GStreamer installation is
missing a plug-in. (12)
but for this error message I've only found errors like this, on other
distros, that
do nothing good on Fedora:
https://bbs.archlinux.org/viewtopic.php?id=138027
please help me to find out which package I should install, or setting I
should change.
Alternatively, please just let me know which other video editor can
quickly and surely "clip and save a few scenes from some mp4 files"
which is all I need right now, on Fedora 25, without hunting error
messages, libraries etc..
Thanks!

F26 x86_64 on Macbook Pro?
by Zoltan Kota
Hi,
Recently I didn't follow the informations regarding how Fedora can be
installed on Apple hardware. Anyway, I downloaded the Fedora 26 Live image
to check and install on my old Macbook Pro 3.1. I have a gpt disk with more
partitions that I want to keep. Actually I have two ext4 partitions as well
with old fedora 21 i386 system, that I want to upgrade (reformatting the
root partition). The boot manager currently is Refit.
When I start F26 from USB, refit recognizes it and the live system can
start and seems to work. During installation I choose custom partitioning,
but at that point the installation stucks. It says "No valid boot loader
target device found. ..." Even if I add sda1 efi system partition as
/boot/efi.
Is there any trick or workaround to make it installable?
Best,
Zoltan

Install f26
by Patrick Dupre
Hello,
I prepared my fresh installation of F26.
I have a /boot (500M) partition (actually /boot/efi preformated as ext4).
In the installer, I get:
For a UEFI installation, you must include an EFI system Partition on a
GPT-formatted disk, mounted as /boot/efi
Can it not reformatted the /boot with the correct format (I set reformat
EFI System Partition).
Should I do it with fdisk manually (ef)?
Thank.
