After mounting a SD card kernel complained
May 16 09:37:51 plex kernel: exFAT-fs (sdc1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.Had to install exfatprogs and just run sudo fsck.exfat -v -y /dev/sdc1 and after mounting the error is gone and the copy process has better performance.
Feb 28 09:15:15 nuc kernel: JBD2: journal reset failed
Feb 28 09:15:15 nuc kernel: EXT4-fs (sdc1): error loading journal
The above was in journalctl when mount command failed.
So tried fsck
$ sudo fsck /dev/sdc1
fsck from util-linux 2.39.3
e2fsck 1.47.0 (5-Feb-2023)

After fsck I tried mount and ls which took some time, but fortunately it worked
Couple of days ago I spotted the following issue in journalctl

2 of 2 failed self-tests are outdated by newer successful extended offline self-test # 1After reboot I had to manually start transmission due ConditionPathIsDirectory=/media/usb-4tb/torrent
Finally found the solution at https://unix.stackexchange.com/a/247547/39470
With systemctl list-units --type=mount just list your mounts and add the unit name to After=
My /etc/systemd/system/transmission.service looks the following now
[Unit]
Description=Transmission BitTorrent Daemon
After=network.target systemd-networkd-wait-online.service media-usb\x2d4tb.mount

You might test/check if it isn’t already with
$ xdg-mime query default x-scheme-handler/http
google-chrome.desktop
$ xdg-settings get default-web-browser
brave-browser.desktop
$ echo $BROWSER
/usr/bin/braveTo set xdg-mime
$ xdg-mime default brave-browser.desktop x-scheme-handler/http
$ xdg-mime default brave-browser.desktop x-scheme-handler/httpsSetting BROWSER env via .bashrc or .zshrc just append export BROWSER=/usr/bin/brave
Finally found a solution for grid/mosaic playback of RTSP streams.

My goal was to connect to a remote desktop. Had to tweak systemd to autologin with specific user.
sudo vim /etc/systemd/system/getty@tty1.service.d/autologin.conf
[Service] ExecStart= ExecStart=-/usr/bin/agetty --autologin mike --noclear %I $TERM
I’m a zsh user so had to add the following into ~/.zprofile
if [[ -z $DISPLAY ]] && [[ $(tty) = /dev/tty1 ]]; then
exec startx
fi
So after these changes after rebooting the PC the X server started and I could connect to it.
Just had to start
x0vncserver -display :0 -rfbauth .vnc/passwd Sat Mar 28 16:18:32 2020 Geometry: Desktop geometry is set to 3840x1200+0+0 XDesktop: Using evdev codemap XDesktop: XDesktop: XTest extension present - version 2.2 XDesktop: RANDR extension not present XDesktop: Will not be able to handle session resize Main: Listening on port 5900
The desktop has no public IP so I had to port forward
ssh vnc-server -L 9900:localhost:5900
Now I was able to connect with vncviewer

On my notebook I finally decided to try NetworkManager with its applet
After installing. I had to check status of some networking services and disable them.
systemctl status dhcpcd.service
sudo systemctl stop netctl.service
sudo systemctl stop netctl-ifplugd@eth0.service
sudo systemctl status netctl-ifplugd@eth0.service
sudo systemctl stop netctl-auto@wlan0.service
And then wait for the magic after starting NetworkManager
sudo systemctl start NetworkManager.service
I should have searched for a how to video on YouTube and could save some debugging time with journalctl -f 🙂 After setup I found https://www.youtube.com/watch?v=MAi9DurTRQc

To monitor progress of an ongoing copy or mysql dump import you might try progress CLI tool. Track progress of commands like cp, mv, dd, tar, cat, rsync, grep, fgrep, egrep, cut, sort, md5sum, sha1sum, sha224sum, sha256sum, sha384sum, sha512sum, adb, gzip, gunzip, bzip2, bunzip2, xz, unxz, lzma, unlzma, 7z, 7za, zcat, bzcat, lzcat, split, gpg, etc.
