WSL does not come with, or install an X Window server, by default.
You can, however, install a 3rd party X Window server such as xming or vcxsrv, both of which I have successfully used with WSL Ubuntu.

First, the things you're trying with umask won't work. umask is a per-process thing, and the process that matters is the process creating the file. The umask of the nfs user on the NFS server (if that's what you meant) isn't going to matter when the files are being created by the nfs user on an NFS client, and the umask of the NFS server service itself ...

Have you tried the Disks app ? It's on all the current buntus and mint. Once there, It 'll show you all of the connected drives (mounted and unmounted). Click on the cog icons for the setting and edit mount options.
Now you can also try this from the Terminal Cli . sudo ntfsfix /dev/sdx1 which would be the drive letter and partition number for the NTFS. That ...

In the official Docker example that I had wrongly assumed would work as a test body, there was the following line:
"CpuRealtimePeriod": 1000000,
Which sets a value that, it seems, is not supported by most or perhaps any out of the box Linux distros. Arch Linux master race ;).

Wine works great for older Win NT4/95/98/Me/2000/XP and Vista builds.
It still works for Win 7, 8, 8.1, and 10, but less and less compatibility between these for Wine.
Wine in combination with Direct X, and an Asio driver (ASIO4ALL = free) gives great results.
For 7/8/8.1 and 10, I would try to run the OS natively.
Wine is more of a direct layer, vs in a ...

I installed Ubuntu 19.10 using Quick Create. I did various stuff, but I got it working consistently was:
after starting the VM
waiting for the VM CPU usage dropping to 0% and
only then clicking "Connect".
It behaves as if if graphics output is used, RDP server fails to start.

Try this... set your system etc files for ubuntu back to non-static or the original before anything was changed. Then put your router in DHCP mode. Restart both.

You will need to install and configure a proxy server locally. Whatever you choose to install must, itself, support being configured to use a proxy server.
I would start with tinyproxy (see Ubuntu package tinyproxy ).
It looks like this supports rules for setting some domains via an "upstream". See the documentation:

Partial answer:
Jack detection is independent of the sound output, so it's possibly a hardware problem even though it's detected as lineout.
That said, the most common solution to such a situation is something that's muted or low volume in your soundcard setup.

Bounced into same issue, found zero reference to that service anywhere in the system. I switched to different OpenVPN config so also made a new service for that and wanted to get rid of the previous one.

You only seem to have SSH (port 22) listening. No other server daemons appear to be running.
Specifically, you have nothing on port 3000, so connecting to that correctly returns "connection refused" (if you had it firewalled it would have said, "connection timed out" -- connection refused means you got to receive an answer packet, which tells that the port ...

I had the same issue and forgot about processing order. You need to name your file something like /etc/rsyslog.d/00_tcpconnections.conf so it is processed before other rules in /etc/rsyslog.d/. This is an example for my ocragent script.
# copy to /etc/rsyslog.d/00_ocragent.conf
if ( $programname == "ocragent" ) then {

Just create a file /etc/cron.d/check-battery that contains:
* * * * * root [ "$(cat /sys/class/power_supply/BAT0/status)" = Charging -o "$(cat /sys/class/power_supply/BAT0/capacity)" -gt 10 ] || systemctl suspend

On some systems (e.g. MS-Dos) the pipe is implemented by copying the output of the first command to a file, then running the 2nd command to read from this file.
Unix does not do it that way.
On Unixes it is like a production line. Each stage works simultaneously, reading input and producing output. If process A produces faster than process B consumes, then ...

Both cat and strings, and most similar utilities¹, read a little bit of input at a time, process it, then read more input, and so on. So in your case, cat only reads what less displays, plus a little more that's in transit.
In more detail, the basic operation of cat is:
Reserve a few kilobytes of memory for use as a buffer.
While there's more input ...

This has more to do with how less works than with how cat or strings work.
The cat command will only push data to its standard output, and it will block whenever the pipe buffer between it and strings is full and nobody is reading. cat does minimal buffering by itself, and the pipe buffer is typically small.
This is also true for strings. It will ...

Pipes have limited buffer space, and if a pipe reader (such as less in your example) does not read more data from the pipe, the writer will be blocked after filling the buffer. This will affect the strings command, which in turn will block the cat command after its pipe is full.
Naturally, the cat command cannot read the whole sda device contents into main ...

I also tried a lot to do this. Actually there is a term for this called "persistence". In my experience, it works only when I create the bootable usb drive with Rufus.

If you run
ll -d /var/log
Then you'll see that it is owned by root (possibly with syslog as the group) and has 755 or 775 permissions which means that while others can read and traverse the directory, only root (and possibly syslog) can modify it. ice-message-initiator.log is in /var/log and while ubuntu is its owner, ubuntu doesn't have modify ...

This configures /usr/bin/python
Apparently, that is not what you are running.
Try running:

This will tell you what python you are running. It might be a private script or link, or it might be an alias.

I looked at a related question.
There might also be path hashing involvement.

I do not believe you can declare an rtmp {} block from within the /etc/nginx/sites-enabled directory.

You can replace nullok_secure with nullok in /etc/pam.d/common-auth. You may also need to adjust values in /etc/pam.d/sshd if you have some specific overrides.

I've identified the issue.
The speakers emit the static when they are charging! After a while the battery was full and therefore the static stopped. If they're operated solely on battery, the static never starts.

I'd take a guess that the virtualenv is being activated in .profile, which doesn't affect cron.
I'd suggest activating the venv in the crontab line:
SHELL=/bin/bash

Setting SHELL=/bin/bash is not really mandatory, but will get you closer to the "usual" environment.

If port forwarding is not an option, the only thing I can think of is SSH remote port forwarding, which is fairly straightforward.

You could also run gnome over ssh. But this will interfere with the system on the local.
Or you can use VNC over ssh. ssvnc on the local, and a vnc server on the remote. I ssh in and launch a vnc server on the remote, setting it to localhost only (then only anyone on the remote (or with ssh connection) can access the vnc server).

Your problem is that you're trying to use a modern desktop environment with an ancient video card that cannot support it.
