nobody's questions

I'm running Lubuntu 22.04. For PS4 I created on an usb-drive with an exfat filesystem; I so not remember if it was with newer exfatprogs or with the older exfat-utils.

Question:

sudo dump.exfat /dev/sdc1
exfatprogs version : 1.1.3

Free Clusters:                          2434069

Shows the dump of the filesystem wich I used for creating it.

I want to give the exfat filesystem a label, but I do not know if I have to use tune.exfat or exfatlabel - or does it not matter which one I use?

How can I replace a UUID in a /boot/grub/grub.cfg with sed?

For some reason I have to replace string 88411b09-1aaa-4775-9fc7-f60041049d6c with f210c829-2c04-4963-9a78-d61cf8ebbd48 in a /boot/grub/grub.cfg I found this but I'm unable to adapt it to my situation. And I found also this but I get an error.

grep -q 88411b09-1aaa-4775-9fc7-f60041049d6c /media/alex/f210c829-2c04-4963-9a78-d61cf8ebbd48/boot/grub/grub.cfg && sudo sed -i 's/88411b09-1aaa-4775-9fc7-f60041049d6c/f210c829-2c04-4963-9a78-d61cf8ebbd48' /media/alex/f210c829-2c04-4963-9a78-d61cf8ebbd48/boot/grub/grub.cfg

I'll try to send me a text reminder in lubuntu 20.04. I have 2 in my autostart ($HOME/.config/autostart) one works the second not.

the working executes a bash-skript that is placed in /usr/local/bin/ for the second I create a desktop file under $HOME/.config/autostart/

cat .config/autostart/firefox-hold.desktop 
[Desktop Entry]
Exec=/usr/bin/notify-send "firefox auf hold gesetzt"
Name=firefox-hold
Type=Application
OnlyShowIn=LXQt;
Version=1.0

I activate it in

lxqt-config-session

looking in .xsession-errors

+ /usr/bin/notify-send -i /usr/share/icons/gnome/48x48/status/dialog-warning.png Warnung 'home voll' # the working one

from the second

notify-send \"firefox auf hold gesetzt\" #looks strange

In Terminal the command notify-send "firefox auf hold gesetzt" works.

I'm running lubuntu 20.04 with sddm as display-manager.

Whenever I logout over gui and login as a different user the user-session is not be killed (do not know if it is by-design). So loginctl shows me doupple sessions for my users.

All sessions from my 2. user I killed with

killall -u second_user_name

for my main user 3 sessions remains.

The session with the lowerst session id i could remove with

sudo loginctl kill-session 3

Leftover

loginctl list-sessions 
SESSION  UID USER SEAT  TTY
     11 1000 alex seat0    
     21 1000 alex seat0    

Next try

alex@Guilmon:~$ sudo loginctl kill-session 11
[sudo] Passwort für alex: 

alex@Guilmon:~$ loginctl list-sessions 
SESSION  UID USER SEAT  TTY
     11 1000 alex seat0    
     21 1000 alex seat0    

2 sessions listed.
alex@Guilmon:~$ 


How can I get rid of it? Or avoid this situation (more than one session per user)

I made a terminal record with the script tool.

mediainfo video 
General
Complete name                            : video
File size                                : 1.29 KiB

I can play it with scriptreplay. Is it possible to convert it to a GIF, for example with ffmpeg or another program?

To clarify, I mean script from the bsdutils package, not a program script. I thought that the saved file is a kind of video, so I can grep some frames/pictures and create a GIF of it.

I hope it is more clear now.

yesterday I updatet my lubuntu 20.04 that shipps a new kernel. I bootete it today up and get

dmesg | grep -i hard
[    0.040601] Booting paravirtualized kernel on bare hardware
[    7.514435] e1000e 0000:00:19.0 0000:00:19.0 (uninitialized): Hardware Error

[   14.944977] e1000e 0000:00:19.0 eth0: Hardware Error

So I search in dmesg for previous boot with linux-image-5.4.0-74-generic

grep -i hard /var/log/dmesg.0
[    0.039776] kernel: Booting paravirtualized kernel on bare hardware

I found bootoption

pcie_aspm=off

But would this not deactivate Active State Power Management for all pci devices? Or I'm wrong? I take a look in

Is there a possibility to deactivate power management for my ethercard there?

Note I have no idea if the card is in this state works (no router here). .

I'm running lubuntu 20.04.

In /etc/fstab I mount my Debian-home filesystem and from that a bind mount for an folder.

cat /etc/fstab

The user in debian and ubuntu are the same name and (id/gid). I can mv or cp files from ubuntu $HOME to bind folder.

but somehow find is not working.

Is my bind mount not right? Or did I oversee something by my find command?

Right now I would download a small video from walkthroug from a game. so I started with

alex@Guilmon:~/Videos$ sudo youtube-dl -U
ERROR: can't find the current version. Please try again later.

after little bit searching I found this and this too

Is there an alternative? with my current version I am not able to download it

Note: I can not skript. I found this this question and followed the link in the answer, but I do not know what I have to do.

I'm running lubuntu 20.04 (is upgrade from 19.04-->19.10) The most time my network connection is to an guest account from a neighbor. the signal is sometimes weak, and I lose the connection; then the notification daemon gives me a bubble. this is annoying when I look videos. I'll try to exclude both nm-tray and NetworkManger through

lxqt-config-notificationd

and in file

$HOME/.config/lxqt/notifications.conf

but I have no Idea how to make it right.

this is after I try it from gui fronted.

cat .config/lxqt/notifications.conf 
[General]
__userfile__=true
blackList=nm-tray, "  NetworkManager"
server_decides=5
spacing=6
unattendedMaxNum=10
width=300

It looks for me wrong.

Note: After upgrade to lubuntu 20.04. I changed my config to

cat .config/lxqt/notifications.conf 
[General]
__userfile__=true
blackList=nm-tray, NetworkManager
placement=top-right
server_decides=5
spacing=6
unattendedMaxNum=10

when I plugin the harddrive it mounts well. But yesterday my filemanager hangs during I search for datas on it.

The harddrive was tested before I replace it with a greater one, and is not used very often. How can I check this harddrive. I tried several cabels. I have only one chassis.

Note I can boot my bionic on it without any Problems.

sorry for much text.

Now i get fdisk output

yesterday i made a clean install of ubuntu19.04. Over /etc/fstab I mount my debianhome and make a bind mount to an folder.

In both systems the 1.user is the same name.

but I was suprised which permissions are ubuntu shown in the folder.

ls -al jd2/

---snip

I boot debian, but the gid is 1000 from my user, all okay there.

grep samba /etc/group
sambashare:x:1000:alex

and

id 
uid=1000(alex) gid=1001(alex) groups=1001(alex),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),117(lpadmin),1000(sambashare)

How can I fix it, without destroying the whole system?

sudo groupdel sambashare

and

sudo groupmod -g 1000 alex

Have I afterwards to change the rights in my $HOME? is think so.

I saw during boot an error with something from selinux. So I searched for related packages on my System and found

libselinux1

I start a simulation with apt.

apt --dry-run purge libselinux1
NOTE: This is only a simulation!
      apt needs root privileges for real execution.
      Keep also in mind that locking is deactivated,
      so don't depend on the relevance to the real current situation!

It is annoying. I cannot deinstall it, because it will also removes lightdm.

I decide to install ubuntu disco. Is it possible to do it without grub?

I want, that debian grub2 stay the main bootloader. Debian-loader is in /dev/sda and my bionic grub2 in /dev/sdb

I want that both are untouched.

yes, I could tell ubiquity to install grub2 on a USB stick and after that I can remove the bootcode.

I read online the manpage from ubiquity and do not find any option for that?

My systems are in bios-mode.

I have to make a fullbackup of my ubuntu bionic. I run

sudo lsblk -f /dev/sdc

If I understood right, it has something to do with suspend to disk. Can I remove this mark swsuspend without formating swap? I will avoid to change The UUID in /etc/fstab a.s.o.

I'm using in xubuntu bionic as shell bash.

I'll try to expand my $PATH for my user over $HOME/.profile.

if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

if [ -d "$HOME/.local/bin" ] ; then
    PATH="$HOME/.local/bin:$PATH"
fi

The result is a little bit unexpected.

echo $PATH
/home/alex/.local/bin:/home/alex/bin:/home/alex/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

$HOME/bin is set twice. How can I avoid it?

In $HOME/.bashrc is nothing declared.

Since about a week I mis the notification bubble when changing volume or pluggin my headphone. I'am runnung ubuntu bionic with pure xfce4-session, meaning metapackage xubuntu-desktop is not on my system.

P:S error is not in /home. Testuser and guest-session same.

I wrote an udev-rule and a systemd-unit, so if I plugin a particular harddrive rsync backups my /home in background and play a audio file when ready.

During my first attempt I get following error pulseaudio[8802]: [pulseaudio] main.c: Unable to contact D-Bus: org.freedesktop.DBus.Error.NotSupported: Unable to autolaunch a dbus-daemon without a $DISPLAY for X11

Note this I have fixed. I got my sound back after skript is ready.

But I don't understand why pacat or even aplay needs this variable for playing only audio. I'm runnning ubuntu bionic with xfce4-session.
