In the past when I had problems connecting to a device that "used to
work" I would deleted it from BT's list of known devices.

However, recently I discovered that "deleting" and "unpairing" are
distinct operations.  I could not move a kbd to a different system
by deleting it from the first, I had to unpair the kbd before it 
would pair with the new system.

I hate deleting config files.  In this case I might
make a directory "/usr/share/logwatch/scripts/services/.orig"
and move amavis there.

Perhaps an even better solution is to copy logwatch's
config file "/usr/share/logwatch/default.conf" to an
alternate name (eg. /usr/share/logwatch/default.conf.orig)
and edit the working copy.  It suggests keeping the
default "Service = All" followed by a line like
"Service = "-amavis".

My bad, you are certainly correct.

BTW, the script contains the author/maintainer's name
and email address.  Perhaps a note to him is in order.

Is this an error in the man page or, more likely,
is my understanding of keepcache faulty?

Perhaps "True" means `all' downloaded packages remain
in cache but if "False", only uninstalled ones are kept.

When I upgraded to F22, all fstab entries that said mount at boot
had to succeed or the boot went to emergency mode.  For me it
was an obscure sshfs mount that caused problems.

Are any boot time mounts failing?

Fedora 22 upgrade oddity

[Jon LaBadie]

Using "fedup", I upgraded from F20 to F21 and a few
weeks later to F22.  The F22 upgrade resulted in a
couple of problems, one of which I'll describe here.

After the F22 upgrade, the boot would hang at an early
stage.  I could still boot F21.

Eventually I discovered that dracut was encountering an
error and not producing the file "/boot/initramfs-".

However, the next step of the kernel installation,
grub2-mkconfig was still producing a grub menu entry for
the kernel, but without the necessary last line
"initrd16 initramfs-".

I feel grub2-mkconfig, after the dracut failure,
should not have produced the menu entry at all.

From F21 I tried to manually run dracut to generate
the F22 initramfs.  Dracut complained about a missing
"bootchart" module.  Yet the F22 repositories did not
contain a bootchart package.  So I reran dracut with
options to ignore bootchart and it succeeded.  grub2-
mkconfig also made a correct boot menu entry.

Further research indicated that bootchart was moved
from being a separate package that was invoked by kernel
boot options to be a standard part of the default
kernel.  When dracut searched for the bootchart module
it encountered a "left-behind", separate bootchart package,
correctly deduced it was the wrong module and failed.
But as noted, grub2-mkconfig completed without showing an error.

Once I removed the old, separate bootchart package
kernel installations, dracut, and grub2-mkconfig all
went smoothly.

In summary, the installation of a new kernel can
seem to complete successfully and yet have encountered
critical errors.  In my case dracut failed but its
error was not considered fatal and the installation
completed as if successful though the new kernel
could not be started.

Correction accepted.  Reword the passage to:

  After the F22 upgrade, booting the F22 kernel would hang at
  an early stage.  I could still boot either of the two remaining
  F21 kernels.
   
But that has little impact on the tale.

Here is a shot at it.  Assumptions include the team names are
longer than shown so I left room for up to 15 chars and for
the sorting to work as I have it, the names can not have spaces.

awk '
BEGIN { SortCmd = "sort -nr -k 8" }

NR == 1 {
printf "%-15s %5s %5s %5s %6s %6s %6s %6s\n",
"TEAM", "W", "L", "D", "GF", "GA", "DIF", "PTS"
}

NR > 1 {
dif = $5 - $6
pts = $2 * 3 + $4
printf "%-15s %5d %5d %5d %6d %6d %6d %6d\n",
$1, $2, $3, $4, $5, $6, dif, pts | SortCmd

I'm unclear about what is needed for your second variation.
It seems that the input data should have numbers in the PKS
column indicating how many extra points they should receive.
In that case, simply adjust the terms calculating "pts"
(something like pts = $2 * 3 + $4 + $7) and the corresponding
arguments to printf.

Yes, put it into a file and make the file executable.

To work with different data files, change my "datafile" argument to
"$1" or perhaps "${1:?need a data file name}".  Then you would
execute it as "progname datafile".

BTW personally I avoid naming a program with its language
as an extension.  Your program is "teamstats".  Why do you
care that it is a shell script, a python script, a compiled
C program or ???

For example, suppose in the future you decide to rewrite it
in python.  Now it would be called teamstats.py.  But people
are used to running teamstats.sh.  You have to "retrain" them.
If you leave off the extension no retraining is needed.

keyboard oddity

[Jon LaBadie]

For several years I have used a Logitech K800 keyboard on my
primary desktop, currently running Fedora 22.  Recently it
has been acting up, sending a stream of fives (5's) as if
I was holding down the five key and it was autorepeating.

The 5's would appear sporadically, sometimes once a day,
other times every couple of minutes.  They appeared in
xterm's, browsers, and other GUI apps and also when I
switched to one of the virtual consoles not running
X-windows.  The 5's also appeared in virtual guest OS's.

Assuming my keyboard was bad I purchased another kbd,
Logitech K330.  As expected, no 5's streamed from this
new kbd.  However when I installed the suspect K800 kbd
on my other system (running CentOS 7.1), it acts normally,
no 5's.  Swap it back to Fedora 22, I get 5's.  It has
now been back to the CentOS system for 10 days and has
not acted up once.  Only on Fedora 22.

Any clue as to what might cause such behavior on one
system but not another?

Thanks for the "identifier".  My search turned up nothing.

I considered the Unifying Receiver also but all 3 I had on hand exhibited
the same behavior.

What does the "file" command say about the .pat file?

  $ file *.pat

In file's "magic" file (/usr/share/file/magic)
these comments appear:

  # XCF:  file(1) magic for the patterns used in the GIMP (.pat),
  # #   developed by Spencer Kimball and Peter Mattis
  # #   ('Bucky' LaDieu, n...@vt.edu)

So maybe it is a gimp pattern file and not something from photoshop.

No, I said I got the numbers from lsusb.

Here is one line of lsusb output:

Bus 003 Device 002: ID 04a9:2206 Canon, Inc. CanoScan N650U/N656U
    
   ||

   Vendor ID, likely 1004 for your LG vendor

Re: Cannot access my phone storage from fc22

[Jon LaBadie]

From what you've said neither the computer nor the
phone seem to realize they are connected.  Perhaps
it is cable problems?  Either a bad cable or the
wrong type.  I read about some phone that needed
a "usb serial" cable rather than a standard usb cable.

Other than that, I've got nothing.

Good luck and HNY!

My system has the last 4 lines the same as yours.  The first is
not present in my "# systemctl -l | grep udev" output.

A "systemctl status systemd-udev-settle.service" says it is loaded
but not active.  A guess, perhaps it becomes active when a new
device is connected.

Putting on my Way-back-hat, that sounds like what I used to
see when multiple processes were trying to read from stdin
at the same time.

For me it happened most often on Solaris when X would crash
and the display manager would not restart.  There might be
a shell process and a terminal login process, or two login
processes competing for the tty input.

Good thought.  I removed ~/.config/gnome* and
~/.config/gconf* as well.  Same "opps" screen
when attempting to login to a gnome DE.

On F22, my LG tablet connects using the mtp protocol.
However, I had to add it to the udev rules configuration file.

I copied /usr/lib/udev/rules.d/69-libmtp.rules to
/etc/udev/rules.d and edited the copy.  I found
rules for tablets similar to my own and duplicated
them but with an appropriate name and with the vendor
and product id's I got from lsusb.

gnome won't start

[Jon LaBadie]

On my F22 system I typically use mate as my desktop environment.
Occasionally I log out and try to login using gnome.  It quickly
comes up with a screen saying "Opps, something has gone wrong".

If I try "gnome classic" instead, it takes a little longer and
I get a flash of an new desktop before the "Opps" screen.

After the failed login, I went debugging by logging into a
tty terminal.

Looking at ~/.xsessionerrors there are 4 lines of
"stty: standard input: Inappropriate ioctl for device"
and nothing else.

I don't notice any errors in /var/log/Xorg.0.log*.

If I try it logging in as a new user with gnome it starts
up fine.

If I remove ~/.gnome* and ~/.gconf* the problem still occurs.

Any hints where to look?

To the latter point, I run Windows 8.1 as a VirtualBox VM under F22.
The space for all my VM's is in a single LV with a ext4 filesystem.
It can be resized as needed.

I don't know about other virtual environments, but under VBox, access
to the Linux data is simple, called shared folders.  Normally I make
my F22 home dir available as a share (e: drive).  This is one directory
tree on an ext4 fs in an LV.

To try other combos today I shared /usr/local, the root of an ext4
fs again in an LV.  I also shared /tmp, a memory based tempfs.
Again, a simple "fill out a gui form of 5 items".

aliases are not intended to be used with positional parameters.
You will need to use functions to do that.

As to the space, "x", not "x 1" gets replaced by the
alias definition.  So

  $ x 1

becomes

  $ echo PAR=$1 1

As noted above, positional parameters to not exist for aliases
so this becomes

  $ echo PAR= 1

To confirm $1 is not interpreted, try

  $ x now is the time

which becomes

  $ echo PAR= now is the time

Whoops, sorry, I forgot PROCINFO doesn't sort the array,
it affects how the array is accessed.

Does this work?  Choose which ever function suits your direction.


#!/bin/awk -f
{
  lines[NR]=$NF " " $0
}

function cmp_str_index(i1, v1, i2, v2)
{
# string index comparison, ascending order
v1 = v1 ""
v2 = v2 ""
if (v1 < v2)
return -1
return (v1 != v2)
}

function rcmp_str_index(i1, v1, i2, v2)
{
# string index comparison, decending order
v1 = v1 ""
v2 = v2 ""
if (v2 < v1)
return -1
return (v2 != v1)
}


END {
 PROCINFO["sorted_in"] = "rcmp_str_index"
 for (i in lines) {
  line = lines[i]
  j=index(line, " ")

You are not "using" multiple DMs, you have chosen to use one of several
DMs available.

I wonder also.

In my dnf history, the oldest copr- related items are updates
last August.  The total dnf history goes back to September 2014
while running Fedora 20.  So they must have been introduced
before then.  Why I have no recollection!

Unless someone suggests otherwise, I'll probably erase the
entire copr set + dependencies.

copr-selinux dependencies Fedora 22

[Jon LaBadie]

Trying to update on F22.  DNF reports copr-selinux
version 1.40 is available to replace v1.35 but it
can not due to "broken dependencies".

rpm says "policycoreutils-python-utils" is required but not
installed.  "policycoreutils-python" is installed and dnf
says it required package is not available.

rpmfind shows the "policycoreutils-python-utils" available
for F23, but not for F22.

Suggestions for how to resolve the situation?
I don't anticipate using copr, perhaps remove it?
Do any system functions depend upon copr installation?

Thanks Tim, that seems to have done the job.

I checked and in my current session mate-settings-daemon was running.
But it was not checked as an auto-startup program.  Probably something
else caused it to run, perhaps my launching the keyboard properties
program.

Anyway, I checked it to run at startup and the volume keys were
active without my taking any action.

I keep it pretty tight already.  That is probably why the settings-daemon
was not checked.

Keyboard Volume Control Keys

[Jon LaBadie]

Running F23, mate desktop and compiz.

Each time I login the three volume keys on my
keyboard cause no action.  If I go into the
program "/usr/bin/mate-keyboard-properties"
either as a CLI or the System->Preferences menu
and immediately exit the keys work as expected.

Can anyone suggest a way to activate the volume
keys automatically on login?

Thanks,
Jon

Mate has that also.  Typically I leave it set to not automatically
save.  Then when I want to change my starting session I set things
up the way I like, turn the setting on and logout.  Next login,
(i.e. immediately) I turn it off again.

I've saved a session with the keys functioning but it had no effect
on them next login, they were off.

One other bit;  I'm using a Logitech wireless keyboard, model K800.
It shares the "Unifying" usb-receiver with my mouse.

Mate's keyboard properties dialog shows many Logitech models but
not the K800.  I've set the model type to generic "Logitech Cordless".

Simplified as "ls -lcd /"

However, "c" is not "C"reate time, but inode "C"hange time.
Add or remove and entry from / or modify permissions or

Don't remove either one.  They are managed by the system.
They are taking no disk space (unless memory becomes full
and it will then use swap).  They are not even taking
significant memory.  In fact 989 is using 0 memory.
Why are you so intent on removing things working as
they should?

Probably user 989 is your login display manager.
Check who 989 is in /etc/passwd (grep 989 /etc/passwd).
On my system is it "lightdm".  I have a /run/user/966.
My 966 is "sddm", my display manager.

The "3" of 38 is setaf, the 8 is the first part of the color
specification.  This 3 number combo is used only on terminals
capable of more than the standard 8, typically 256 colors.

I think the "5" seems to be constant, perhaps meaning a color
beyond the std 8 and the 33 completes the color specification.

Couple of points.  I don't think you can reserve a partition for the
use of a tmpfs.  It uses your RAM memory and swap space instead.

You could add /dev/sda10 as another swap partition.  Then perhaps add
the fstab entry.  However, I think systemd has a way mount /tmp as a
tmpfs without having an fstab entry.

If you want to use your partition as /tmp but have it cleaned out at
boot, check the manpage for tmpfiles.d

Its been ages so I may have faulty memory.

The compiler can generate code to "profile" a piece of code.
As I recall the profile included info on number of times a
function is entered, total time spent in the function, and
maybe min/max times in the function.

You only need to add the profile option for the code you are
interested in.  And perhaps at the link stage also.

I too looked at a S3100 manual and found this strange footnote:

  Notes on Connecting the Camera to a Printer
  • When Auto is selected for Charge by computer, it may be impossible to
print pictures with direct connection of the camera to some printers.
If the PictBridge startup screen is not displayed in the monitor after
the camera is connected to a printer and turned on, turn the camera off
and disconnect the USB cable. Set Charge by computer to Off and
reconnect the camera to the printer.

Perhaps check if your "Charge by computer" setting is auto and turn to off.

It seems to be a recurring defect.  Some kernel releases exhibit it others
do not.  Last I looked in to it (maybe 9 months ago) it wasn't solved and
was being called the Marching Fives.

Nope.  Two systems, Fedora 22 and CentOS 7.1.  Both use the "unifying"
USB dongle from Logitech that handles both mouse and keyboard.  But the
mice and kbds are different.  One keyboard acted up on Fedora, kbd swap
cured the problem.  Swap back, problem back.  Moving mice and usb
receivers did not affect the problem.  It stayed with the one kbd and
Fedora.

Next F22 kernel update, no problems with either kbd.  Typically I don't
reboot right after a kernel update.  When I do reboot it is usually into
a different kernel.  On one reboot the problem reappeared.  Another kernel
update appeared just a day or two later; problem gone.

Motherboard has headers for 8 USB ports, none go to a hub or splitters
except for one header feeding a front panel memory card reader.  I'm only
using 2 other USB port, both of which are wired directly to a header.

The "unifying" dongle normally is on a 30 inch extension cable.
But I did try it directly in a USB port without the extension
and the problem persisted.

How do you address the remaining F18...F2x packages.  Which should be,
can safely be, and shouldn't be removed?  My system also was upgraded
many times.  There are lots of older distro packages still installed.

One I got rid of was bootchart from F18.  It prevented my complete
upgrade to F22.

Stimulated by this thread I looked at the still installed old packages.
Gee, F-spot from F18.  Who knew it was dead?  That pkg is gone now.

But what about things like 4 packages named "Fedora-UserManagement-*"?
Are they still needed?  Were they ever?  Are they no longer updated
because they have morphed into something else?

And what about "hardinfo".  Wonder if the F18 version still runs.
Yup, looks like a useful inventory tool.  Wonder why its no longer
available.

Not really looking for answers to these specific questions.  Just
wondering how other people deal with decision making, "should they
stay of should they go"?

The inode may not be allocated to a file and thus available for allocation.

UNIX systems had a program fsdb (file system debugger) that let you
view and edit components of a file system.  Is there a similar program
for ext-X file systems?

It sounds like the file manager doesn't refresh its list
of files in the current directory after your rename.

What if you force a refresh.  Say leave the FM and reenter.
Or switch to several directories and return to the one
containing "bar".  Or create another file/directory.
Gee, I wonder if you could get two "bar" files by
creating another one while the FM doesn't acknowledge
the first one.

The '*' means "zero or more digits".  Don't forget that zero.
The first match is where there are zero digits, i.e. at the
beginning of the line.  So sed replaces it with "//" (nothing).

Try sed 's/[0-9]*/X/' to confirm.

You really want sed 's/[0-9][0-9]*//'  which reads a digit
followed by zero or more additional digits.

Traditionally sed has used basic RE syntax not the extended
syntax that includes "+".  If the OP uses a sed such as
exists on my systems, you can get extended RE syntax with
the "-r" option.

   sed -r 's/[0-9]+//'

Samuel, does your sed support extended REs by default?  If so,
what system has that version?

With your own domain name you could also set up your own mail server
at least for the inbound email.  Doing that gives you an unlimited
number of "email accounts".  I'm currently approaching 400 aliases
to "jon".  If I start a new relationship with a vendor or a mail list
I create an additional alias.  My filtering pulls out various things,
like this list, and at the end splits into "jon" and "NotToJon".

If any of the aliases begins to get spammed, I set the server to reject
that address and, assuming I want to continue the relationship, have to
establish a new address only with the one vendor.

Having multiple email accounts (seldom given out, and real accounts,
not the aliases I mention above) has saved my butt a couple of times.

dnf - deprecated update cmd

[Jon LaBadie]

On F22, the manpage for dnf says the update and update-to
commands are deprecated aliases for upgrade and upgrade-to.

That being the case, shouldn't the update-info and
check-update commands also be deprecated and have
corresponding upgrade versions?

If you leave the data as one field per line you can avoid squishing
the team names and not depend on tabs for alignment.

I stopped using the bt mouse.  Even turned off bt in the bios.
Will revisit the issue with the trusted setting and report back

IIRC, yesterday you were labelling /dev/sde1, not sdd1.
Did it get enumerated differently today?

If the system consistently mounts the drive to a specific
location (ex /run/media/bobg/ you could make a
symbolic link to the mount point in your homedir,
say /home/bobg/extdisc.  If the drive is mounted you
have an easy to use path to it.  Otherwise it will
just be a broken link, no problem.

Look into keyboard and mouse wireless dongles that are not bt.
My desktop tower is pretty far behind me.  I use a Logitech
kbd  They use a single, tiny usb dongle for both.  It
was too great a distance, so I added a usb extender cable
to get the dongle closer.  Works great.

When I ran the simple "hdparm -t" tests on the same

It seems "trust" is the key.  I had difficulty turning it on for
my mouse device.  In blueman-manager, there are menu items and
a separate icon button to turn on trust.  These did not complain
but didn't set the mouse as a trusted device either.

I went into bluetoothctl, found the device id, and used the
trust  command.  It reported setting "trust succeeded".
Sure enough, when I went back into the gui blueman-manager,
it was showing the trust icon for my mouse.

Now rebooting with the mouse on, or starting the mouse after
booting, it comes right up.

Seems like blueman-manager needs a fix to get trust working.

See my posting today "RE bluetooth mouse   [SOLVED]" for a fuller
description.  In short, I had tried to set the mouse to a trusted
device using blueman commands such as blueman-manager.  I tried
again but it did not allow automatic connection of the mouse.

Now I tried the "trust" sub-command of bluetoothctl.  It did
succeed in setting the mouse as a trusted device.  And the
mouse automatically connects after boot.

In another thread ("fedora 23 bluetooth connection") the
"Trusted" setting for a BT device was mentioned.

Previously I had tried to set my mouse as a trusted device
using the GUI configuration tool "blueman-manager".  When
I clicked on the "trust" icon or on the "trust" menu icon,
nothing seemed to happen but no error messages came up either.

I revisited the problem and repeated the above observation.
Then I tried the "bluetoothctl" command, finding "trust"
and "untrust" commands were available.  I ran the "trust [dev]"
command, it reported "trust successfully applied to [dev]".
And over in the blueman-manager, a trust icon appeared on the
mouse entry.

Even better news, when I reboot, if the mouse is on it is
connected and active.  If the mouse is not on, turning it
on automaticall connects it and it is active.

Sounds like there is a problem with blueman-manager!

radiotray and gstreamer plugins

[Jon LaBadie]

The current thread on "listening to online broadcasts"
stimulated me to ask about problems with the one I
like, "radiotray".

A number of stations I try to listen to, including some
preconfigured ones, fail with a list of procedures from
gstreamer that suggest a plugin is missing.  But it
does not say which.  As far as I can tell I have just
about every gstreamer plugin installed and see no way
to determine what may be missing.

Scouring the net comes up with lots of reports of
similar error listings, but no "solution" has worked
in my environment.

Here is a sample listing:

  gstdecodebin2.c (3576)
  gst_decode_bin_expose():
  GstPlayBin2:player
  GstURIDecodeBin:uridecodebin9
  GstDecodeBin2:decodebin29:

I have the same problem on Fedora 22 and 24.

That could result in double spaced "output"

Two more possibilities (the short output lines were unchanged):

# search for entire string, replace only txt
$ sed '/foo(.txt.)/s,txt,/dir/txt,' tst.txt
foo('/dir/txt')
bar('txt')
foo('bar')
foo("/dir/txt")
bar("txt")
foo("bar")

# capture unchanging parts as \1 and \2 using grouping \( & \)
$ sed 's,\(foo(.\)txt\(.)\),\1/dir/txt\2,' tst.txt
foo('/dir/txt')
bar('txt')
foo('bar')
foo("/dir/txt")
bar("txt")
foo("bar")

When I had to replace the MB of a similar, older system, I used a non-HP MB.
Later when I wanted to beef it up, the new MB only had 2 SATA ports and
I wanted to install more drives.  So I purchased a really cheap SATA
controller card.

I got a store-brand SSD and to my surprise the MB controller did not
see it but the cheap controller did.  Blaming the store-brand SSD,
I returned it and got a Crucial SSD.  Same problem though.  So it
was the controller, not the SSD.  MB controller worked fine with
other SATA drives, but not with the SSD.

I'll mention one of my pet peeves (kinda like RLS's UUOC* award).

In a simple pattern matching grep RE, a repetition operator, '*'
(and in egrep '?'), is useless at the start or end of the pattern
and may reduce grep's efficiency.

  grep .*abc
  grep   abc.*
  grep .*abc.*
  grep   abc

Will all match the same set of lines.

Note, I'm not referring to some situations where anchors are used
(ex. 'abc[0-9]*$'), or sed substitutions, or even grep with the
'-o' option to output the matched portion.

Yeah, my other laptop was so bad I got a Logitech mouse with their
miniscule "unifying receiver" dongle.  But the Vostro has been fine
over about an 7-10 yr period.  The problem only arose after installing
F24 over F17.

Sorry, what I meant to point out (poorly), was my BT is an
internal adapter, not a dongle.  Of course it could be connected
to an internal USB port.

Is /etc/mtab a file or a symlink to /proc/mounts?  The mount
manpage says it should be the link due to userspace problems.

Alrernatively, add 2> /dev/null   or use --no-mtab.

Agreed, their scrollwheel sucks.  Plus they never seem to have
left and right tilt.  I use that to flip between workspaces.

BTW the Broadcom BT adapter in my laptop seems to present as
a USB device:

What about /etc/mtab.  Is it a file or a link?

BTW On my system /etc/mtab -> /proc/self/mounts despite
what the manpage says about pointing to /proc/mounts.
It is "not wrong" however, my /proc/mounts also points
to /proc/self/mounts.

bluetooth mouse

[Jon LaBadie]

I have an old Dell Vostro 1500 laptop.  It was running
Fedora 17 with no problems with the bluetooth mouse I use.

After a fresh install of Fedora 24 Workstation I can't
get the mouse to reconnect after a boot.  Systemctl
reports bluetoothd 'Failed to obtain handles for
"Serviced Changed" characteristic'.  Both blueman-manager
and blueman-applet report the adapter is off and are
unable to turn it on.

I can go into bluetoothctl, power on the adapter and
connect to the mouse.  Things are fine until a reboot.

lshw reports the bluetooth adapter is a Broadcom BCM2045.

Any thoughts on how to get the adapter powered on at boot
and the mouse auto-reconnected as it nicely did 7 Fedora
releases ago.

Thanks, Jon

F24 gnome login failure

[Jon LaBadie]

On my F24 laptop I typically run in a Mate environment.
Yesterday I tried to login to a gnome environment.
After entering my password there is a little pause,
screen blanks, and a fresh login screen comes back.

Looking at logs, the only error I find is:

  fatal ... could not find org.gnome.Shell.desktop

That desktop file exists on none of my systems
and dnf provides '*gnome.shell.desktop' returns
nothing.

As a no brainer I eliminated all traces of gnome
and gconf under my home directory.  Result was
same error.

Any suggestions?

Yes, I did.  Also under ~/.local.
I finished with find's of "-iname '*gnome*'" and "-iname '*gconf*'".

One further test, created a new user and it could not login into
gnome either.

I think I got a similar message when I turned off the

was the "Error In Progress" that I recall.

There are no pam modules there specific to desktop environments.
There are mate- and cinnamon-screensaver modules.  Several
pam modules have "gnome" references, but all are to the keyring.

I'm sure there are others, but here are two suggestions.

I notice for 4 environments on my F24 system (gnome, mate,
plasma, and cinnamon), each set the environment variable
DESKTOP_SESSION.  Unfortunately I don't have xfce installed
to check it.

At the login screen, after your user id is selected or
typed in, but before entering your password, look for
an icon that drops down a menu of available desktop
environments.  It will default to your most recent
session and you can select a different one if desired.

Marching 5's again

[Jon LaBadie]

Has there been any resolution to the "marching 5's" syndrome?
As I recall it seemed to be kernel release specific.

After 6-9 months of no extraneous 5's, I've got the problem
again on F22 with kernel 4.4.13-200.

They may be FUSE, file systems in user space
and thus not in the kernel.

mate-terminal launcher oddity

[Jon LaBadie]

On a Fedora 25 system running the mate desktop environment
I have three terminal launchers in my top panel.  The
commands executed are:

 1.  mate-terminal
 2.  mate-terminal --geometry 96x30+130+280 -t MUMS -x ssh -Y mums
 3.  mate-terminal --geometry 96x30+90+130 -t CYBER -x ssh -Y cyber

If # 3. is launched when no other terminal session is running two
similar sized windows appear, one with the ssh session, the other
with no shell or ssh apparent.  If either window is closed, the
other closes as well.

But if another terminal session, 1. and/or 2. is already running
when I launch 3., 3. comes up as a single window.  Actually I
briefly see the extra window, but it immediately closes leaving
the one containing the ssh session.

I never see the extra window behavior when the nearly identical
launcher 2. is executed.

Perhaps the odd behavior of launcher 3. is somehow related to
mate-terminal running as a single process no matter how many
terminals are open.  But why the different behavior of 2. vs 3.?

A caveat I think the OP already found out.  Both the sourced
script and the function would be running in the users
interactive shell environment, it must for the cd to be effective.
Thus you do not want to "exit" from either the sourced
script nor from the function as that causes the interactive
shell to exit.  In the function you can use "return "
instead of "exit ".

Two things come to mind.

compiz problems

[Jon LaBadie]

Running Fedora 25 with a Mate desktop environment.  I ran
the same on F24 and still do on another system.  I would
prefer to use compiz as my window manager.  However it is
unusable.  If I move a window, images trail the movement
and remain when I stop.  Popup menus don't disappear when
I make a selection.  Killing a window does not cause its
image to disappear.

All the residual garbage is cleaned up if I change
workspaces and change back again.  But the desktop
wallpaper is gone too.

I don't run any of compiz' fancy features, wobbly
windows, etc.

Any idea what might cause this problem?

radiotray, gstreamer plugin

[Jon LaBadie]

Using "radiotray" in a mate environment on Fedora 24.

For many stations I get the following warning message:

  Your GStreamer installation is missing a plug-in.
  gstdecodebin2.c(3576): gst_decode_bin_expose (): \
/GstPlayBin2:player/GstURIDecodeBin:uridecodebin7/ \
GstDecodeBin2:decodebin26: \
no suitable plugins found

So far as I can tell, all the available plugins for
gstreamer and gstreamer1 (12 each) are installed.

How can I determine what is missing?

Several problems.  The sed's I know don't use extended RE syntax
and '+' is a repetition character of extended RE.  Some sed's
might allow its use with the '-r' option.  And maybe there are
some sed's that do use extended RE.

Comma is not typically a special character, so no need to escape.

In pattern matching by the shell, the '*' repetition character
does not reference the preceeding character.  RE repetition
characters (* in basic and + and ? in extended) always refer
to repetitions of the preceeding character.  Thus your pattern
(if and extended RE) would be looking for a string of commas,
NOT one comma followed by a string of any char.

Try something like "sed -r -i 's/,[0-9]+$//'".
or "sed -i 's/,[0-9]*$//'" or if uncertain they
will be digits, but certain they will not be
commas (i.e. you want to delete the last comma
onward) try "sed -i 's/,[^,]*$//'

Isn't there a mouse setting for how rapid the clicks

Two other considerations:

Where is the output from the pipeline sink (wc -l in this case)
going to go?  Without the ssh connection, it will go to stdout,
either closed or set to /dev/null.

When the ssh connection terminates, I suspect its children
processes on the remote to receive the "Hang UP" (your parent
has died) signal and will likely commit suicide.

calendar program loops

[Jon LaBadie]

Upgraded to F24 and had a big surprise this morning,
a mail queue clogged by over 400,000 messages.

Root runs a nightly cronjob of "/usr/bin/calendar -a"
to look at each users calendar file and send notices
of upcoming events.  The new version loops endlessly
through all the users.

If I run calendar as myself without the -a option
it doesn't loop.  Run it as "sudo calendar -a" and
I have to kill it quickly or the mail system will
clog again.

My google and bugzilla search did not find any
comparable reports.  Is anyone using this ancient
command with the -a option?

And check that each user knows how to set-up their
own crontab, is allowed, and does if they want
the service.

The '#!' notation has meaning ONLY if it is the first two characters
of the file.  Otherwise it is just a shell comment.

From the command line you are probably running bash.
Thus the script gets executed by the shell you want.
But during boot it may be executed by a different shell
and that shell may not deal with some constructs the
same as bash.

Ed,
I'm not having problems, but not having noticed those

Is that the typical status for a running system?
