Is there an attribute or approach to allow/force rsync to redo a
"complete" xfer of files..?
I'm sure there is but I must be missing it..

System-wide callgraph profiling no longer possible?
by Clemens Eisserer
Hi,
I would like to use oprofile to analyze some interaction between a poor
performing graphical program and the Xorg x-server.
In the past I remember sysprof and orpfile worked very well for this kind of
analysis, giving a detailed overview/callgraph which function consumes
how much time and how it was called.
However on fedora 27, despite having all the debuginfo-packages
installed, I don't get a useful callgraph.
Most functions are directly one hirarchy below the Xorg process,
regardless whether I use sysprof or oprofile.
Any ideas what could be wrong with my system?
Thank you in advance & best regards, Clemens

This tutorial is showing the color palette and the status bar.
The status bar is displaying current fill/stroke colors on the left of the status bar.
The color palette allow fast/repetitive color selection.
see View->Show/Hide, select Palette, select Status Bar

This tutorila does not show the Stroke Style tab usage
(which is the third tab after Style, and Stroke Tab,
which is needed to select both left and right arrows using markers line.
hope it help

4k playback with VLC and Kodi
by lejeczek
hi everyone
I wonder if anybody has seen hardware fully decoding 4k
264hon Fedora.
I have a Panasonic camera which produces 4k 264h MP4 and I
see different results with various player.
VLC - plays no video, shows no errors, just plays but with
black/blank screen. Also Gnome's Videos does the same.
Kodi - plays video content okey butit decodes with software,
does not seem to use hardware.
Would you know it there is a problem with HW assisted 4k
decoding? Is it gstremer?
Also, why Kodi would not use HW for 4k when it does it with
1080p?
I'm obviously also anxious of whether it's just one type of
HW platform or all. I'm on AMD APU/GPU.
many thanks, L.

how to digitize a sizable CD collection using fedora?
by Robert P. J. Day
one of my new year's resolutions was to digitize several hundred
music CDs in preparation for figuring out what system to use in the
domicile to play them, but regardless of how i decide to eventually
play these CDs, i'm looking for recommendations for how to rip them to
hard drive before i decide how i will end up using them.
given the cheapness of hard drives (and that i have a QNAP NAS
anyway), i don't really care about disk usage, so i figured on ripping
all of those CDs using (lossless) FLAC format, and i can decide down
the road whether to convert them to a different format to save on
space.
in short, any recommendations on simply ripping all these CDs to
hard drive, while having no idea what i will eventually use to play
them?

KDE doesn't start after upgrade to Fedora 27
by Dave Close
I have two systems that were recently upgraded from Fedora 26 to 27
using DNF system-upgrade. Both were successfully running a KDE desktop
for several generations previously, including on F26. In both cases,
after the upgrade, starting KDE showed the splash screen and then
a blank screen with only a pointer cursor. The keyboard and mouse
worked but the screen remained blank. Both systems are set to start
in systemd's multi-user mode; KDE is started with the startx command.
One of the systems is a 32-bit laptop with little local content. I
chose to simply do a fresh install on this one to get it working
quickly. Fedora doesn't offer an installation image for 32-bit F27
so I installed F25 and then did successive upgrades to F26 and then
F27. KDE worked in both F25 and F26 but had the same problem once
I got to F27. I did it again and stopped at F26 to have a working
system.
The other system is a modern 64-bit desktop with 8GB RAM. This one
still has the problem. I'd like to find the cause and a solution
before I make the effort to revert to F26 because this one has
a huge amount of local content which I would have to backup and
restore. (I do backups but more for recovery of individual files;
a general recovery could have other problems.)
Note that Gnome works on this machine (but I hate Gnome).
The logs haven't given me any clue as to the cause of the
problem. I have now run "startx &>logfile" hoping that might tell
me something. After the blank screen appeared, I killed xinit and
Xorg from a different console. The logfile is included below in the
hope it might spark some insight from the group.

Cannot upgrade libdvdcss after a recent upgrade push

This morning I received a notice that a new version of libdvdcss was
available.
But when I tried to upgrade it, the upgrade choked on a problem with the
GPG key.
Here is the output of "sudo dnf upgrade libdvdcss," redacted to remove

All right, so it's the wrong key. Now how and where do I get the /right/
