UPDATE to F30. and Fixed acpi (see grub commandine below)

NVidia driver issues still persist, but I finally debugged (and disabled) acpi consistent errors that had be plaguing me in F27.

I added a kernel boot param to my Grub2 commandline.

  • acpi=off

use the following to fix grub

grubby --info=ALL
grubby --remove-args="acpi=off" --update-kernel /boot/vmlinuz-5.4.19-100.fc30.x86_64

grubby --set-default /boot/vmlinuz-5.4.19-100.fc30.x86_64
grubby --info=ALL

You can also remove a kernel from the grub menu with

grubby --remove-kernel=/boot/vmlinuz-5.5.10-100.fc30.x86_64

You can also remove the actual kernels

rpm -qa kernel

dnf remove kernel-5.5.16-100.fc30.x86_64

Bluetooth Pairing to HP mouse with no pairing code

by tgutwin

Posted on Tuesday Jan 26, 2016 at 08:32PM in Technology

Fedora Icon[FIXED] The Gnome Bluetooth GUI via settings FAILS to pair with my HP Bluetooth Laser Mobile Mouse. This has not worked in the gui bluetooth settings app for a few versions (maybe F19).The problem is that the mouse does NOT have a pair code, and the it won't pair with '0000' or '1234'.

I figured out to manually pair it from the commandline without a pairing code!

use bluetoothctl on the commandline

use the following commands to connect to the MAC address...

My New Raspberry Pi2 running Fedora 21 with Full JAVA JDK

by tgutwin

Posted on Tuesday Jan 26, 2016 at 08:23PM in Technology

Raspberry IconI Got a Raspberry Pi2 ! It has a 900MHz quad-core ARM Cortex-A7 CPU  and 1GB RAM.

I first tried noobs with Debian and it ran out of the noobs box very well.  The noobs version of Fedora DID NOT because it was not built for the new version of the ARM processor in the Pi2. That was no big deal because thanks to user clivem on the Pi Forums an image was avaialble.  See the forum link for the details. It is a full F21 version that is called FIDORA.

It was very easy to get this working. It is Fedora 21 for the ARM, with full yum repo support including rpmFusion.

Small PHP/OwnCloud issue during Fedora 20 to 21 upgrade

by tgutwin

Posted on Monday Jan 25, 2016 at 06:30PM in Technology

After succesfully upgrading F20 to F21 using Fedup (on my server); my Owncloud CRON install was not working.php logo

Cron entry looks like:

*/10  *  *  *  * apache php -f /var/www/html/owncloud/cron.php

So I tried it on the commandline and an error told me that the new
upgraded version of PHP had a change in the default setting (in
/etc/php.ini)  for always_populate_raw_post_data. It told me to set it to:

always_populate_raw_post_data = -1

The cron now runs without error.

Upgraded Fedora 20 to 21 with Fedup

Fedora LogoSuccessfully went through a workstation upgrade  Fedora 20 --> 21 using fedup instructions at

The only issue I had (and expected ) was an nVidia driver problem that was easily fixed.
F21 installed version 346 but my GT9600 based card needs the 340.


sudo yum remove xorg-x11-drv-nvidia xorg-x11-drv-nvidia-devel kmod-nvidia

sudo yum install xorg-x11-drv-nvidia-340xx akmod-nvidia-340xx kmod-nvidia-340xx



Stunnel to Gmail on Fedora 20 with systemd

by tgutwin

Posted on Monday Jan 25, 2016 at 06:24PM in Linux

How to setup stunnel to simply redirect a non-SSL email client to send mail through a Gmail or (Google Apps) account. Installed on Fedora 20 (or o other Fedora with systemd) as a systemd.service.

I have some devices in my network that are not capable of SSL email required by Gmail accounts. No problem stunnel can easily wrap the messages in SSL from GMail. Stunnel can do soooo much more, but for this simple usage, the setup is very easy.

1) yum install stunnel

2) edit the /etc/stunnel/stunnel.conf to look like...

client = yes

accept  = YOURSERVERIP:465
connect =

Make sure to change YOURSERVERIP to your own IP addr.

3) create a systemd.service file to start and autostart stunnel at startup:

Description=Stunnel SSL Tunnel

ExecStart=/bin/stunnel /etc/stunnel/stunnel.conf

# Give a reasonable amount of time for the server to start up/shut down


4) Start stunnel with   systemctl start stunnel.service

5) enable it to autostart   systemctl enable stunnel.service

6) send a test email, but point your client at YOURSERVERIP with your Gmail user password.

Works for me!

New Zoneminder install on Fedora20 (from Source)

by tgutwin

Posted on Monday Jan 25, 2016 at 06:22PM in Technology

I updated my Zoneminder installation to the latest version (1.27 master branch) from source at GitHub. My intention is to get the latest version that has an updated FFMPEG library and the libVLC. My original intention was to also building x264 and ffmpeg from source to ensure I have all codecs compiled in from the start.I did not have to do that because the Fedora20 Packages from RPMFusion already have what I needed (that makes life easier). I have done this before (see for by past experiences.

I am also re-installing the OS - Fedora20 to get the latest security updates.

The Zoneminder wiki has pretty good instructions.
The forum also has a very good summary of installing from RPMs

This post documents my steps
