Artifacts running konsole under Fedora-35
by Jonathan Ryshpan
I've just upgraded from F34 to F35 and have troubles with KDE vs
Wayland and X11.
Wayland is very flaky, crashes of various kinds, sometimes killing
individual apps, sometimes an entire session. I can't reproduce the
crashes reliably; they happen when they happen. The only thing that may
be relevant is that I am running Firefox with many (probably too many)
windows and tabs.
X11 messes up konsole, the KDE terminal emulator. When typing onto the
screen, not displaying text generated by an application, the test
appears slowly and with many strange artifacts. It looks like the text
appears on one interlace and then gradually gets better; the text takes
about 500 msec to recover; the same thing happens with window
decorations when I mouse over them. I have attempted to record screen
behavior using simplescreenrecorder, but when I start it, the problem
goes away.
Right now I'm using X11 with gnome-terminal, which doesn't show the
problem.
System is:
Operating System: Fedora Linux 35
KDE Plasma Version: 5.23.4
KDE Frameworks Version: 5.89.0
Qt Version: 5.15.2
Kernel Version: 5.15.12-200.fc35.x86_64 (64-bit)
Graphics Platform: X11
Processors: 8 × Intel® Core™ i7-4790K CPU @ 4.00GHz
Memory: 15.5 GiB of RAM
Graphics Processor: Mesa Intel® HD Graphics 4600

Samsung Smart TV "crashes" NVidia driver, can't detect TV any more?
by Rogan Dawes
Hi folks,
I have a 43" Samsung Smart TV that I am using as a monitor with a ThinkPad P51, running Fedora 35 Workstation Edition. This laptop has a "NVIDIA Corporation GM206GLM [Quadro M2200 Mobile] / Mesa Intel® HD Graphics 630 (KBL GT2)" graphics subsystem. As far as I can make out, I am using the latest NVidia driver (495.46).
What is unfortunately happening, is that if my laptop goes to sleep, the TV sees that the source disappears, and "tries to look for the laptop", repeatedly. This ends up waking up the laptop (sometimes), until the TV eventually gives up and turns itself off. The problem is then that the laptop no longer detects that the TV is connected to the HDMI port, and I have to reboot to allow the laptop to detect the screen again. Xrandr does not detect the display if run manually, and the Settings app Displays page also doesn't show the TV.
This is a rather difficult thing to google, I have had zero results in my searching.
I also tried looking for any logs that would indicate what went wrong, but I found nothing in the syslog, etc.
Can anyone give me pointers on how I can start debugging this? I am fairly technical, so can certainly follow instructions. I'm guessing I need to enable verbose logging for the driver so it can report when new displays are connected or disconnected, as well as any actions around those events?
Thanks

SSL Level?

Hi All,
Is there a way to get one of those fancy tool
in nmap to tell me the "level" (version)
of SSL and/or TLS that a web site is using?
Many thanks,

Hello,
When I run octave with
pkg load symbolic
and
syms x
I
get
Symbolic pkg v2.9.0: Traceback (most recent call last):
File "<stdin>", line 28, in <module>
AttributeError: '_PrintFunction' object has no attribute '__globals__'
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 12, in octoutput_drv
File "<stdin>", line 54, in octoutput
File "<stdin>", line 55, in octoutput
AttributeError: module 'sympy' has no attribute 'compatibility'
Closing the Python communications link.
error: Python exception: AttributeError: '_PrintFunction' object has no attribute '__globals__'
occurred in python_header import block.
Try "sympref reset" and repeat your command?
(consider filing an issue at https://github.com/cbm755/octsympy/issues)
error: called from
pycall_sympy__ at line 191 column 5
valid_sym_assumptions at line 38 column 10
assumptions at line 82 column 7
syms at line 97 column 13
It seems that it is an identified bug, due to sympy
This is really more than annoying.
if we cannot use the symbolic package with octave
Do you more about the future of this packages?
Thanks

I never suggest Fedora users run ‘pip’ as root, except when in a virtualenv, dockerfile or some contained environment.
It is far too easy for pip to overwrite or override a packaged python library and break system tools, such as the ones used in DNF. Once you’ve broken dnf, it is hard to fix those libraries since dnf is the tool to fix them.

Well, you are doing it in a way that will break your OS, eventually. It’s not a question of DNF becoming “tougher”. You are suggesting people use two different package managers, simultaneously, and neither knows about the other.
Imagine hiring two builders to install a new furnace in a house, and not telling them about the other. You’d end up with two confused builders and a broken furnace.
If you want to use pip as root and can’t be bothered to use virtual environments, install python outside of DNF, either from source into /usr/local or /opt, or use something like “conda”, which has its own prefix. Then, at least if it breaks something, it won’t prevent you from updating your OS.
FWIW, in Centos 8 stream, DNF uses a python that isn’t installed as /usr/bin/python so it is less likely for ignorant people to break, although I’ve discovered that Ansible *does* find it and will happy install python modules in it and break things.

Improper shutdown, now Kernel panic.
by murph nj
Hi all:
I've got an odd problem that I was hoping for some help on.
The laptop was previously working fine, I am running F30, updated regularly.
I've got an Acer laptop that has been shutting down suddenly. (I
suspect a bad battery, working on that.)
After a sudden shutdown last night, I now get a kernel panic on boot
right after "Starting Switch Root..."
I was able to boot from a USB stick, and was able to read the journal,
but I didn't see anything obvious to help.
I was able to get all of my data off of the (encrypted) disks, so
that's not a problem, but I don't want to just give up, and wash and
reload too quickly.
Any suggestions?
Thanks,
