System issue w/ Neptune 5.3

System issue w/ Neptune 5.3
I noticed something strange when I logged into the gray log-in box in Neptune 5.3. I always log in as a regular user. Alongside the names of regular users for whom I created accounts is systemd Core D... appearing in the list of users when I type
$cat /etc/passwd
is the line
Code:
systemd-coredump:x:998:998:systemd Core Dumper:/:/sbin/nologin
Is this some kind of system issue? Or has my computer been hacked?

I just installed security updates to qt5.... and libqt5.... libraries using apt-get.

Is there anything else that I should do ?

The only strangeness I am presently experiencing w/ Neptune 5.3/KDE is that sometimes my mouse stops working (moving the mouse cursor) and hangs for 5 to 10 seconds before it acts normally again.

One strange behavior I am presently experiencing w/ Neptune 5.3/KDE is that sometimes my mouse stops working (moving the mouse cursor) and hangs for 5 to 10 seconds before it acts normally again.

UPDATE: KDE failed.

For some reason, every time I tried to reboot Neptune 5.3, the gray user-login dialog box associated with the K graphical user interface never appeared. Instead, the terminal got dumped into a white-on-black text console mode login.

So I rebooted from the Neptune 5.3 Live DVD in order to write this on the web. I also ran a filesystem check on my hard drive as superuser, which showed it to be clean/uncorrupted.

Next, I checked /var/log/messages and discovered a few hundred lines (approximately!) that look like this:
Code:
Jan 27 12:14:51 neptune1 baloo_file:  KDE Baloo File Indexer has reached the inotify folder watch limit.   File changes will be ignored.

I don't think this KDE failure is related to my earlier problem of systemd Core D... in the user-login screen, but obviously, I could be wrong.

Is there anything I can do to get KDE to run on this machine? Earlier this morning, I gt an error message in a KDE pop-up dialog box saying something like "KDEInit error" when I clicked on an icon corresponding to a text file in Dolphin.

Is it possible to re-install KDE onto my hard drive using apt ?

No everything is ok.
They just decided to lower the UID so that they are visible in the login manager.
The Login Manager has a minimum UID setting not show all system users but only normal users.
If you set this version higher in /etc/sddm.conf
e.g.
Code:
MinimumUid=1000
The systemd-coredump user should vanish on a restart of sddm.

So the graphical user interface failed to come up.

When you are able try to get the /var/log/Xorg.0.log file with information about the error (marked as (EE) in that file) of the installed system.

I think this Xorg.0.log file is the one on the Neptune 5.3 Live DVD filesystem. How do I access the one on my hard drive (/dev/sda1) while running from the live DVD ?

RE: System issue w/ Neptune 5.3
Just mount the installed system with the live managers filemanager and navigate to the one file from the installed system.

Thank you, leszek. I found it. It was the File Manager that allowed me to mount /dev/sda1 as /media/sda1
Code:
user@live-pc:/media/sda1/home$ ls -Fdltr /var/log/Xorg.0.log

RE: System issue w/ Neptune 5.3
Two days ago, I remember seeing an error message with the word KDEinit or kdeinit in it, right before the boot-up process stopped in a system console login prompt. I wrote it down, but this morning cannot find the piece of paper I wrote it on.
So after mounting the hard drive w/ Disk Manager 1.1.1, I decided to do some exploring...
Code:
root@live-pc:/media/sda1# find ./ -name "*[Kk][Dd][Ee]*init*" | xargs ls -Fldtr
-rw-r--r-- 1 root root  275752 Mar 21  2017 ./usr/lib/kde4/libkdeinit/libkdeinit4_kwalletd.so
-rw-r--r-- 1 root root  163848 Mar 21  2017 ./usr/lib/kde4/libkdeinit/libkdeinit4_kuiserver.so
-rw-r--r-- 1 root root  122352 Mar 21  2017 ./usr/lib/kde4/libkdeinit/libkdeinit4_kglobalaccel.so
-rw-r--r-- 1 root root   52280 Mar 21  2017 ./usr/lib/kde4/libkdeinit/libkdeinit4_kcmshell4.so
.
.
.
srw------- 1 root root       0 Jan 30 17:33 ./kdeinit5__0=
root@live-pc:/media/sda1# file kdeinit5__0=
kdeinit5__0=: cannot open `kdeinit5__0=' (No such file or directory)
root@live-pc:/media/sda1# ls -Fdltr ./kdeinit5__0=
ls: cannot access './kdeinit5__0=': No such file or directory
root@live-pc:/media/sda1# ls -Fdltr ./kdeinit5_0=
ls: cannot access './kdeinit5_0=': No such file or directory
While many files were listed, only the last one in the list was from the date two days ago. Not sure what this file even is. Might it be possible to log into the system installed on the hard drive and reinstall KDEinit (or even X) using APT or some other system tool?

The only other solution I can think of is to reinstall from this Neptune 5.3 LiveDVD.

Might it be possible to create a partition that is not under /home, like say /extra-file_storage or /efs on the hard drive to move /home/user files into so they don't get clobbered by reinstalling Neptune 5.3 in the way I described? Or does reinstalling from the Neptune 5.3 LiveDVD destroy the entire partition? If this is the case, then I will use my backup hard drive, which Disk Manager 1.1.1 sees, as a repository for some user files.

UPDATE: startx failed from my hard drive after logging in as root

Not sure what you are doing but you are showing me the Xorg.0.log of the live system again. I need the one from the installed system so /media/sda1/var/log/Xorg.0.log
