Samsung Smart TV "crashes" NVidia driver, can't detect TV any more?
by Rogan Dawes 24 Jan '22

24 Jan '22

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 Rogan

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, -T

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?

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. -- Jonathan Billings

Improper shutdown, now Kernel panic.
by murph nj 23 Jan '22

23 Jan '22

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, --murph

systemd killing processes on monitor wakeup?
by Raman Gupta 22 Jan '22

22 Jan '22

I have a couple processes that have been consistently dying every time I wake up my monitors after the system has been idle. One is Slack Desktop and the other is IntelliJ IDEA. Plasma also crashes on every wakeup, which may or may not be related. I used an eBPF program (killsnoop.py at https://github.com/iovisor/bcc/blob/master/tools/killsnoop.py) to trace where the signal to shut down these processes was coming from, and it appears that systemd is sending pretty much every active process signal 15 and then 18. TIME PID COMM SIG TPID RESULT ... on monitor wakeup ... 12:16:58 2551 systemd 15 2938613 0 12:16:58 2551 systemd 18 2938613 0 12:16:58 2551 systemd 15 2938814 0 12:16:58 2551 systemd 18 2938814 0 12:16:58 2551 systemd 15 2938832 0 12:16:58 2551 systemd 18 2938832 0 12:16:58 2551 systemd 15 2938978 0 12:16:58 2551 systemd 18 2938978 0 12:16:58 2551 systemd 15 2939432 0 12:16:58 2551 systemd 18 2939432 0 12:16:58 2551 systemd 15 2939899 0 12:16:58 2551 systemd 18 2939899 0 12:16:58 2551 systemd 15 2942192 0 12:16:58 2551 systemd 18 2942192 0 ... Process 2551 is the user process for systemd: raman 2551 1 0 Jan07 ? 00:00:10 /usr/lib/systemd/systemd --user This behavior is relatively new. What is going on here? I haven't found any other reports of this behavior anywhere else. Regards, Raman
