laptop freezes when screen is blank (when closing the lid)
by Jan-Erik Wichmann
Hi,
I have some problem with my laptop freezing when the screen is blank.
Basically every time I lock the screen (or close the lid) my laptop freezes and cannot be woken up anymore.
The screen will stay black regardless of which buttons I press.
The only way to recover is to press and hold the power button to shut off the computer.
Obviously, that's not very convenient.
Even more so as I cannot even bring my laptop to someone else's desk to quickly show them something; I first need to reboot at their place.
My coworkers are already making fun of linux and how it is not suitable for laptop use and maybe I should consider switching to Microsoft Windows instead.
They say: "Well, it is open source, so why don't you just go ahead and fix the problem yourself?"
I wish I could, but I do not even know where the issue is.
journalctl seems to be unhelpful (see below of the output right before the hard reboot).
So, any ideas of how to debug and hopefully solve this problem?
Thanks a lot!

OT: Command-line tool on Fedora 32 to remove a small portion of mp4
by Ranjan Maitra
Hi,
I am writing to ask if there is a way to remove a small portion of a mp4 file. Basically, the file is my lecture (has both audio and video
recorded using simplescreenrecorder) and I want to remove a portion of the mp4 (from the 14:30 to the 15:50 time-points) of an mp4. The mp4
itself is currently 17:50 minutes long.
Is there a way to do this, using a command line tool (preferred) or something else? I like command line tools because they are faster.
Thanks,
Ranjan

VideoConference Package?
by John Mellor
In this extended period of Covid-19 isolation, is there a
videoconference package available?
Hosted systems like Zoom are not opensource, do not use a browser as a
client, feed connection data to Facebook, only allow 2 participants for
free, and not available for a local install.
I thought of Webex, but its Cisco. Maybe its just me :-)
I took a quick look at Jitsi, but users say it has a fatal extreme
processor utilization bug, the rpm packages are 3 years out-of-date, and
does not seem to be present in the normal rpm repos.
I also took a quick look at BigBlueButtion, which looks pretty good.
However, it only runs on an ancient version of Ubuntu, and uses a shell
installer for some unknown reason.
This seems like a major application type that appears to be completely
missing from the repos. Is anyone building one, and just hasn't
announced it yet?

Chromium OS / Fedora / cros-termina ??
by David
This is a follow-up, about my post a few days ago that I had purchased
a real computer running Chrome OS. It is actually running Chromium OS.
My goal is to someday get Fedora running in a virtual window on my ACER
24 Chromebase computer.
The Linux Beta feature that is so easily activated is apparently something
called "cros-termina."
cros-termina - Version: 13099.48.0 is my current version, which I think has
an
available update.
I do not yet have any idea how to add Fedora either to replace Debian or to
in some
sort of other option.
I think most users would not want to run several distros, as the virtual
machine is
so slow and so small.
To add to my confusion, I have almost zero experience with virtual
computing - maybe
none, unless you count briefly looking at a new iso of a distro in Gnome
Boxes.
For anyone interested Chromium OS has 14 visible components. You can
view the names
of those components on your Chromium device, by typing,
"chrome://components."
Some of mine are: ME Preload, Legacy TLS Deprecation Configuration, Adobe
Flash Player,
Intervention Policy Database [ email me if you want the
others ]
I got into this accidentally, and have not followed previous internet news
stories about this
topic, nor yet seen any videos on YouTube.
But I am super duper impressed so far. I hope my future emails to you
will be coming
from the Linux-virtual-machine on this device and hopefully eventually with
Fedora.

Calibre and Python
by Patrick O'Callaghan
Since F32 now has Python 3 as the default, I find that some Calibre
plug-ins no longer work, though Calibre itself is fine. For the moment,
I'm running it in an F31 VM to get round this, but there must be a
better way. I expect it involves environment variables but am too lazy
to experiment, so if anyone has done this I'd appreciate a hint.

launch applications always in the same position/same monitor
by Frederic Muller
Hi!
I'm looking for the above mainly for Thunderbird (which a web search
didn't give me much) but would be happy to do with other apps, under
GNOME 3.
Any idea if this is even possible?
Thank you.
Fred
ps: I mentioned same monitor as actually when switching 1 monitor
orientation from landscape to portrait then half of my apps change
monitor.... should I file a bug or is it to little a problem to even bother?

ssh reverse tunnel as a service?
by Alex Regan
Hi, I have a fedora32 system behind a firewall without any access from
the outside. I'd like to build a reverse ssh tunnel so I can get to it
from my remote location while working remotely. I'm familiar with how
remote ssh tunnels work, but can't quite get systemctl to create a
proper service, presumably because ssh expects to be tied to a terminal.
I've built the following shell script. I believe "bash -s" can be used
to spawn processes not connected to a terminal.
# cat /etc/init.d/ssh-tunnel.sh
#!/bin/bash -s
ssh -i /root/.ssh/orion-key -R 43022:localhost:22 root(a)orion.example.com
I was using this script in a unit file, but got closer to what I want by
placing the ssh command itself into the unit file as the ExecStart
parameter.
# cat /etc/systemd/system/connection.service
[Unit]
Description=Reverse SSH to orion
After=network.target
[Service]
Type=forking
#EnvironmentFile=-/etc/sysconfig/sshd-permitrootlogin
#EnvironmentFile=-/etc/sysconfig/sshd
#ExecStart=/etc/init.d/ssh-tunnel.sh
ExecStart=ssh -tt -i /root/.ssh/orion-key -R 43022:localhost:22
root(a)orion.example.com
#ExecReload=/bin/kill -HUP $MAINPID
User=root
KillMode=process
Restart=on-failure
#RestartSec=42s
[Install]
WantedBy=multi-user.target
I also read that -tt can be passed to ssh to start it on a pseudo-terminal.
I then added the unit file as a service using "systemctl enable
connection.service"
Can someone guide me on the unit parameters I should be using for this?
Should Type=forking?

Hi Experts,
I'm using Fedora 32 with MATE Desktop. When I click on a '.flac file in filemanager
audacity starts. How can I change this? I want the play command to start.

possibly OT: emacs update on Fedora does not like my default font
by Ranjan Maitra
Hello,
After last night's update to emacs on F32, I can no longer use emacs with my default font.
When I fire it up, I get a second window open and the following:
Warning (initialization): An error occurred while loading ‘/home/user/.emacs’:
Symbol's function definition is void: set-default-font
To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file. Start Emacs with
the ‘--debug-init’ option to view a complete error backtrace.
----------------
My own .emacs has the following set at:
(set-default-font "10x20")
Any suggestions as to what I should look at/change?
Many thanks and best wishes,
Ranjan
