Where has Xlib.h gone?
by jeff
Wanted to write a program in C , but I can not find the include files to
be able to! I used to have Fedora 7, now have 23, but it doesn't even
seem to be available any more... Anybody know why?

[OT] Building packages with apache-maven
by Earl Ramirez
Good day All,
I inherited a packed that was created for an earlier version of of
Fedora, now I am trying to package it for Fedora 23; however, under the
%build section of the spec file. Apache-maven is used:
%build
export PATH=$PATH:../apache-maven-3.3.9/bin
( cd constants && mvn -X install && cd - ) || { echo "Constants
installation failed" ; exit 1; }
( cd restlet-support && mvn -X install && cd - ) || { echo "restlet-
support installation failed" ; exit 1; }
( cd urlfetcher && mvn -X install && cd - ) || { echo "urlfetcher
installation failed" ; exit 1; }
( cd syslog-processor && mvn -X install && cd - ) || { echo "syslog-
processor installation failed" ; exit 1; }
( cd balcony-tool && mvn -X install && cd - ) || { echo "balcony-tool
installation failed" ; exit 1; }
I added the '-X' do that I can debug the error and the error that I am
getting is:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-
plugin:3.1:compile (default-compile) on project constants: Compilation
failure
[ERROR] No compiler is provided in this environment. Perhaps you are
running on a JRE rather than a JDK?
The output of mvn -v is as follows:
$ mvn -v
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-
10T17:41:47+01:00)
Maven home: /opt/apache-maven-3.3.9
Java version: 1.8.0_91, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.91-
2.b14.fc23.x86_64/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "4.4.8-300.fc23.x86_64", arch: "amd64",
family: "unix"
echo $JAVA_HOME show:
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.91-2.b14.fc23.x86_64
and echo $PATH shows:
$ echo $PATH
/opt/apache-maven-3.3.9/bin:/usr/lib64/qt-
3.3/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/home/eramire
z/.local/bin:/home/eramirez/bin
I spend a few days googling the error and I am seeing the same output
for mvn -v and a few recommended that we simply replace the */jre from
JAVA_HOME; however, this directory does not exists on Fedora even if I
install Oracle Java.
Admittedly I'm stuck and utilise all options to get apache-maven to
work; therefore, I will like to know if anyone can shed some light on
this or can point me into the right direction so that I can get this
resolved. I have also use the version of maven that comes with Fedora
and I am still not successful.
Thanks in advance.

F23: Heavy paging by Xorg during screen unlock
by K. Chowksey
Hi,
I'm using F23-x86_64 on a Dell E6430 latitude laptop with NVIDIA adapter. Sometime in the last 2 weeks, a software update that got auto-installed is resulting in very slow screen unlocks. The screen lock itself is quick (no paging). But when I press a key on the keyboard or move the mouse, there is heavy paging activity on the laptop and it take 3-4 minutes for the password screen to appear. This happens 8 out of 10 times.
vmstat shows free mem drop dramatically from 5G to 46M during the unlock. The RSS size of Xorg grows from 49M to 7G!
The only workaround right now for me is to use wayland, where this problem does not occur. If anyone needs, I have detailed output from vmstat and another script that I wrote to see Xorg's RSS size grow. In case anyone has a workaround for Xorg server, please let me know. Should I be filing a bug for this ?
Best,
Kapil

no more vertical scroll bar on Firefox (46)?
by Frederic Muller
Hi!
Firefox just got upgraded to version 46 and it seems there is no way to
have vertical scroll bars on most websites (I've found a few exception).
Is this a new option and is there a way to set it back to showing those
scroll bars?
Thank you.

Clementine on F23 dies immediately after start
by Frank Elsner
Hello community,
after upgrading my (32bit) System to Fedora 23 from Fedora 22 (went smoothly)
my favourite music player "clementine" doesn't work anymore :-(
Clementine dies immediately after start and /var/log/messages shows:
May 3 16:08:18 siffux audit: ANOM_ABEND auid=1953 uid=1953 gid=12203 ses=1 pid=3285 comm="QThread" exe="/usr/bin/clementine" sig=11
May 3 16:08:18 siffux kernel: show_signal_msg: 42 callbacks suppressed

May 3 16:08:37 siffux systemd-coredump: Process 3262 (clementine) of user 1953 dumped core.
What's going on? Any pointer to a solution very welcome.
PS: Amarok works but is not my favourite. Others I don't like.
Kind regards, Frank Elsner

can't switch from X to tty consoles
by maderios
Hi
Sometimes with F23, after some hours, I can't switch from X to tty
consoles (ex, with ctrl+alt+f2). Consoles are frozen, I can switch only
to tty1, from which I started X with startx. All F23 kernel versions are
concerned, now kernel-4.4.7. Same problem happens with xfce4, fluxbox or
Enlightenment-0.20.x. I don't use any display manager like lightdm, gdm,
etc...
Any idea?

I should know, but can't think of it: how do I get Yumex on
F23xfce to use rpmfusion (and ELRepo if it can)??

systemd-journald slows down boot process
by Clemens Eisserer
Hello,
I recently tried to improve the boot time of a low-end laptop (normal
hdd, no SSD) running Fedora23 (+lightdm + xfce), and disabled unneeded
services which were loaded at boot.
However the systemd-journald.service still takes a lot of time to get
started (11.2s), dispite reducing the maximum log size used by systemd
to 64m (found the suggestion in several forums).
Curently, the critical chain looks like:
[root@localhost elfie]# systemd-analyze critical-chain
graphical.target @20.328s
└─multi-user.target @20.327s
└─NetworkManager.service @18.317s +1.995s
└─dbus.service @16.256s
└─basic.target @16.209s
└─sockets.target @16.207s
└─iscsiuio.socket @16.206s
└─sysinit.target @16.139s
└─systemd-update-utmp.service @16.084s +53ms
└─auditd.service @15.613s +459ms
└─systemd-tmpfiles-setup.service @15.152s +429ms
└─systemd-journal-flush.service @14.511s +621ms
└─systemd-journald.service @3.268s +11.222s
└─systemd-journald-audit.socket
└─-.slice
Are there any tools available for analyzing this any further?
Thank you in advance, Clemens
