Clearing DNS cache without rebooting
by Joe Zeff
Ever since last night, my desktop has been unable to resolve
slashdot.org, but other computers on my LAN can. I'm presuming that
there's something wrong with my DNS, so I'm trying to clear its cache,
but I can't find instructions on how to do this without rebooting.
Suggestions?

MuseScore 4.0
by Jerry James
MuseScore is music composition and notation software, currently
available from Fedora in the mscore package. Version 4.0 was just
released. If anybody would like to try it out, it is available from
this COPR: https://copr.fedorainfracloud.org/coprs/jjames/MuseScore4/.
I do not intend to build for Fedora until some issues have been worked
out.
WARNING! WARNING! WARNING!
DO NOT TRY THIS IN A WAYLAND SESSION. It will run for anywhere from a
few seconds to a few minutes, then abruptly exit with a "Protocol
error". Run an X session to try MuseScore 4.0.
WARNING! WARNING! WARNING!
WARNING! WARNING! WARNING!
Configuration for MuseScore 3.x and 4.x differs in some important
respects. You may have to do a "factory reset" when switching
versions. Run "mscore -R" or "mscore -F" if it won't start. This
will clear out your list of recently opened scores, for example, so
backup your configuration before you do this.
WARNING! WARNING! WARNING!
To try it out, run:
sudo dnf copr enable jjames/MuseScore4
sudo dnf install musescore
Please try the video export option, which has bitrotted upstream. I
have attempted to update it for current ffmpeg. Please let me know if
it does or does not work for you. If it works well, I will submit my
patch upstream. Do this: "mscore --score-video <path_to_score> -o
filename.mp4", and optionally try the --resolution and --fps
arguments. Run "mscore --help" for more information. This
functionality does not seem to be available via the GUI.
Upstream bundles fluidsynth, apparently for the sole purpose of
implementing a caching soundfont loader that uses internal fluidsynth
APIs. I have unbundled fluidsynth for this repository, which means
there is no soundfont cache. If you switch soundfonts frequently,
please let me know if the performance is acceptable. If you are
familiar with the fluidsynth API and can implement a caching soundfont
loader using only public APIs, please do so and submit it upstream.
Several other products are bundled (beatroot-vamp, dtl, intervaltree,
rtf2html, and KDDockWidgets). Each of them has either been altered by
the MuseScore developers or, in the case of KDDockWidgets, internal
APIs are used so extensively that I cannot see how to unbundle
successfully. Thoughts on how any of these products might be
unbundled are welcome.
The COPR version makes a long-requested change: the package name
changes from mscore to musescore. Let me know if you encounter any
problems arising from that change.
A new font package is needed to build version 4.0 for Fedora. I would
appreciate a review from anybody who feels competent to review a font
package: https://bugzilla.redhat.com/show_bug.cgi?id=2152347. There
is a question about the appropriate foundry name. If you can help
answer that question, please chime in.
Regards,

Better way to refresh the Display?
by Javier Perez
Hi
I have a problem. Oftentimes when I press the button on my KVM to return to
my desktop and Fedora 36, the screen is black and unresponsive.
I have to log in through SSH and restart lightdm (systemctl restart
lightdm)
Problem is that it resets my sessions and some programs like cura do not
like that and even trash their configuration files.
Looking through the system log I do not see any problem at the time I made
the switch back to the desktop.
1. How can I troubleshoot why sometimes I can come back and othertimes I
cannot?
2. Is there any less destructive way to recover the display than restarting
lightdm?
I do not have that problem with my other computer, but then, I use it as a
fileserver and it does not have that many programs installed.

How do I identify a bluetooth device in bluetooth add device?
by Stephen Morris
Hi,
I have a pair of "water dancing" bluetooth speakers that I am
trying to get working under F37, I had these working in fedora quite
some time ago and I've forgotten how I got them working. I've gone into
the bluetooth interface in KDE's system settings and clicked on add
device, which then went searching for bluetooth devices it could see,
but all the devices it showed except for one looked like they were mac
addresses. How do I determine which of those is the speakers (if any)
when the plate on the bottom of the main speaker doesn't show a mac address?
Also just on the bluetooth search front, I was sitting next to my
machine wearing a Fitbit Sense Smart Watch with bluetooth active, but
the Add Device search was not seeing that device, but it was seeing my
wife's Fitbit Versa 3 (which is several models below the Sense) and
still seeing it when my wife walked upstairs, until I walked out to an
adjacent room to put my Sense on the battery charger (the battery was 9%
charged) and when I walked back to my machine the Add Device display was
showing my Sense, why?

Youtube Videos Don't Play in Fedora
by Stephen Morris
Hi,
I have booked marked a support/tips page from the suppliers of the
Asus motherboard and the pages the main page links to contains Youtube
videos. The videos wouldn't play in Firefox Nightly, nor would they
display in Google Chrome, they just showed a message saying "If the
video doesn't start to play restart your device", and a reboot of Fedora
didn't change anything.
I've just upgraded to F37 via dnf and loaded the main page into
Firefox Nightly and when I link to a page containing a video, the video
now displays a blue twistie (play button) and continually spins on that
button without playing anything, although it does seem to a cache some
data. In both F36 and F37 when I load the main bookmarked page I have to
do a reload before it will display anything.
When I load the page into Google Chrome in F37, like in Firefox the
page doesn't display the page body and unlike in Firefox it doesn't
matter how many times I reload the page it doesn't display the page body.
How do I determine what the issues are given that the same pages
loaded into Firefox Nightly and Google Chrome in Windows display without
any issues.
regards,
Steve

genisoimage source
by Bill Cunningham
Is there a rep for non developers of the source fro the fedora version
of genioimage. I checked and genisoimage is an rpm of its' own. But
where is its' source? I don't mean the official maintainers of the
genisoimage project, but the fedora 37 version of genisoimage. I checked
src.fedoraproject.org but as far as I could see, it's not there.

Fedora37 NIS logins no audio in KDE/Plasma/X11
by Terry Barnaby
I've just updated a test machine from Fedora35 to Fedora37, most is
working but users logged in using NIS authentication no longer have
access to audio.
The system is using the KDE/Plasma desktop and the sddm login manager
all using X11.
It looks like /run/user/<userid> does not exist and XDG_RUNTIME_DIR is
not set etc.
The system has
/usr/lib/systemd/system/systemd-logind.service.d/nss_nis.conf with the
default contents:
[Service]
IPAddressAllow=any
RestrictAddressFamilies=AF_UNIX AF_NETLINK AF_INET AF_INET6
The first obvious error message in /var/log/messages is:
dbus-daemon[8116]: [session uid=1002 pid=8114] Activated service
'org.freedesktop.systemd1' failed: Process org.freedesktop.systemd1
exited with status 1
The start of .xsession-errors has:
Failed to import environment: Process org.freedesktop.systemd1 exited
with status 1
Any ideas ?
