Good Day..

I am having a funny problem and need some advise. I need to permanently map a window drive on 2 Ubuntu 22.04 machine with same setup and configuration.

Strange thing is one is working but another just doesn't .

//serverip/path /home/ubuntu/pictures ctfs credentials=/home/ubuntu/.smbcredentials,uid=1000,gid=1000,x-systemd,automount 0 0 UUID=F47A-11C2 /boot/efi vfat defaults 0 1

I want to copy appr. 12TB of data from one storage to another on a ubuntu 20.04 machine (ssh terminal, no desktop).

When I would start this with rsync the terminal/ssh session would loose connection after some time and I am not longer able to check the status.

So what is here the best practice to copy big data? Rsync output in file, tmux or some other way, how the pros do this? I am not interestet in getting live information for each file but I want to have information if there is/was an error and maybe an overall/atm status (atm XX percent, running time, avg speed, like that).

I’m experiencing a repeatable crash issue when using Chrome on Ubuntu 24.04. Every time I download a file and then try to open the download list via the downloads button, Chrome immediately crashes.

I’ve already tried several fresh Chrome installations, including a completely fresh Ubuntu installation. The exact same issue occurs with Brave and Chromium as well.

I also tried launching Chrome without GPU acceleration and fresh profiles, but the crash still happens. At this point, I suspect there may be a problem with the NVIDIA driver 580.95.05, which was installed automatically during the initial Ubuntu setup.

Any help or insights would be greatly appreciated.

I wanted to remove network configuration on login screen. I succeeded removing the icons but when I clicked where the icon is supposed to be it is still working… where it is configured ?

I am on Debian 13

Thanks !

I am running Ubuntu 24.04.03 LTS (Kernel: 6.14.0−36-generic) on an Acer Aspire V3-574G laptop.

The machine has a Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter, which provides both Wi-Fi and Bluetooth.

Problem: The Bluetooth adapter is not found or recognized in Ubuntu.  

Context:  

    The laptop is dual-booted with Windows 10.  

    The Bluetooth works perfectly fine in Windows 10.  

    I have already disabled Windows Fast Startup (Fast Boot) to prevent potential conflicts.

The Terminal program does not work. I'm trying to enter text, but the line remains blank. I've seen this before in Ubuntu.

I'm writing about a standard Ubuntu image on an .iso disk downloaded from the Ubuntu downloads page. I installed the OS on my own hardware. It's standard hardware. Previously it was a Windows 11 PC. I didn't change any settings.

There's a simple reason for this. Does anyone know what this is?

I think it's a noob question, Using samba with external 1tb hdd. I have ubuntu server 24.04.

I formated the drive using mkfs.ex4. Out of 931gb that I should be getting only 915gb are appearing and of those I can only use 869gb. That's 60gb lost right there with a formatted drive! I also plugged the drive to Windows to confirm that it is formatted and having 1 partition.

This is sab.conf with spaces of course, it deletes them here. [ex] path = /mnt/ex writeable=yes public=no

I'm using Kubuntu 25.8 on a Lenovo laptop. When I first turn the laptop on the system boots to the Plasma desktop without ever asking for a password. This means that anyone with access to the computer can get right into it.

If, on the other hand, the computer is waking from sleep, it does require a password, which is what I want.

It was not always thus. When first I installed Kubuntu, a few weeks ago, I set a password during the installation and for a while the computer did require a password when starting. Something changed, without any intentional action on my part.

I've combed through the system settings multiple times to try to find a setting to make it require a password, but to no avail. I'm sure there is a setting somewhere, but I don't know how to find it.

Any ideas?

My 24.04 LTS just updated, and it seems to have wiped out CUPS. I have tried sudo apt-get install --reinstall cups - no joy. After research I tried system-config-printer and get a series of deprecation warnings. I have also tried sudo systemctl restart cups and get:

Job for cups.service failed because the control process exited with error code.
See "systemctl status cups.service" and "journalctl -xeu cups.service" for details.

When I go to systemctl status cups.service I get:

Hardware:

MacBook Pro S3 pro
HP Elitebook i7 36g Ubuntu/Windows 11

Needed programs:

VMware Workstation
(need Intel machine to run two Windows Server 2019 VMs, one Windows 11 VM, one Windows 10 VM)

I'm looking for a program that will let me use my HP laptop as a second monitor while also using it as a VM machine. Currently I'm using Windows remote desktop with a Ethernet to Ethernet connection to remote into the HP laptop, but that puts the HP laptop screen into the login screen. I would like to be able to fold it to use it as a second monitor while also remoting into it from my MacBook.

What's the point off letting me turn of "Automatic" and specify what DNS to use, if the network just ignores it?

Go to a wifi network.

IPv4

Disable "Automatic"

Specify a DNS different from the wifi network's default.

Click "Apply"

Look at "details"

DNS4 will be the wifi's DNS, not your specified server(s).

I have a laptop with Ubuntu 24.04.3 with LUKS encryption set up at the time of installation. I wanted to an "key-file in a USB drive" based unlock option so that I don't have to enter the passphrase every time.

To this end I followed the guide LUKS with USB unlock. Unfortunately I made a mistake somewhere and now my laptop does not boot and takes me to the intiranfs prompt.

How do I revert the changes I made to /etc/crypttab and other files using live-USB?

I have google-chrome-stable 142.0.7444.175-1 installed, and I'm trying to use manifests v2

When I open Chrome from the shortcut, it runs a exec commands that I think are configured here /usr/share/applications/google-chrome.desktop there are three different configs [Desktop Entry], [Desktop Action new-window], [Desktop Action new-private-window].

The exec commands look like this Exec=/usr/bin/google-chrome-stable %U for the [Desktop Entry], and similar for the other exec commands. I tried adding flags to the exec commands config, and I do not think that it worked. I didn't test a manifest, but I looked at the chrome://flags, and it didn't tell me about v2.

These are the flags I tried to add, and it looked like this:

Exec=/usr/bin/google-chrome-stable --enable-features=AllowLegacyMV2Extensions --disable-features=ExtensionManifestV2Unsupported,ExtensionManifestV2Disabled,ExtensionsManifestV3Only %U

Here is the entire file, well most of the file, this page has problems understanding Korean, so I have to remove that.

I'm not sure what I should actually do so I can use manifest v2, or if I even should use manifest v2. I also want it to work from the desktop shortcut.

It could be I actually want to edit /usr/bin/google-chrome-stable or it could be I just use Firefox.

I am attempting to dual boot Ubuntu onto my Lenovo Thinkpad P14 Gen 4 (AMD). Windows 11 will be my primary OS, but I wanted to experiment with dual boot, and wanted to do it this way as opposed to a VM.

I followed the tutorial at this link https://ubuntu.com/tutorials/install-ubuntu-desktop#3-create-a-bootable-usb-stick, and I am stuck on the F12 boot menu. The displayed drive shows the NVMe and USB HDD, however Ubuntu does not show up as a bootable OS.

To troubleshoot:

• I utilized both Rufus (see: https://ubuntu.com/tutorials/create-a-usb-stick-on-windows#1-overview) and balenaEtcher software to create a bootable USB.

• Secure boot is off.

• This Thinkpad model has official support for Ubuntu 20.04 LTS per the Lenovo website.

I'd like to set up a Samba-share that is read-only for all devices in my LAN, except for a select few devices (based on IP address) that have write access. I explicitly want to keep the read/write access IP-based as this works best with my devices and network configuration.

I did not find a way to do this in a single share definition, so I tried a solution with two definitions for the same share (seen elsewhere as suggestion), see below. This does not work, however, as the first definition is overruled by the second. In the current order that means that no devices have access to the share except the few with write-access (that part works). When flipped, only the read-only share works and the devices that should have write-access get no access whatsoever.

How can I solve this issue?

Running Ubuntu Server 24.04 with samba 4.19.5.

I'm using Ubuntu 24.04. I tried to print a photo, and my system reports that the printer service seems to be unavailable. I used it yesterday without an issue, but today the printer service is unavailable in the settings screen.

After years I had problem with the AMD driver. Discord crashed while I was sharing my webcam. I tried to update or change to the Ubuntu driver, but I am stuck.

glxgears is working, but makes a noise on the speaker (tested this with the old driver, was not so intense. I'm not sure if it's related.)

At the moment the aim is to be able to use Discord, Steam, and Lutris again. The main window does not launch, just frees the display until I close it.

I tried to uninstall all packages, remove the PPAs that I do not need, and reboot and update and install the packages for AMD support, but that did not work too well. What have I missed? I would like to continue using Ubuntu until Ubuntu 26.04 before doing a clean install.

Edit: The Ask output, I checked the motherboard GPU, should not be configured to be used, as far as I can tell. @user7215 or what are you looking for?

I am trying to create a script that listens to the desktop notifications dbus and print the sender and message to the command line.... the final goal is to run a specific function when I get a specific notification.

I tried using dbus-monitor --session which prints stuff out when I get a notification, but I don't see the actual notification. I had Gemini AI help me write some python code, this code runs, but nothing happens when I get a notification.

It seems like this should be a simple task.... I would rather use a bash script if I could, but python would be fine too.

I did find this post which had a python script that I had to be update to work with py3. This script runs but nothing happens when I get a notification or send one via notify-send

gi.require_version("Gtk", "3.0") # or "4.0" depending on your target GTK version
from gi.repository import Gtk
import dbus

def filter_cb(bus, message):
    # the NameAcquired message comes through before match string gets applied
    if message.get_member() != "Notify":
        return
    args = message.get_args_list()
    # args are
    # (app_name, notification_id, icon, summary, body, actions, hints, timeout)
    print("Notification from app '%s'" % args[0])
    print("Summary: %s" % args[3])
    print("Body: %s", args[4])


DBusGMainLoop(set_as_default=True)
bus = dbus.SessionBus()
bus.add_match_string(
    "type='method_call',interface='org.freedesktop.Notifications',member='Notify'")
bus.add_message_filter(filter_cb)

Thanks.

cd ~/Downloads - no other suggestions resulted in changing the directory.

Something simple, something stupid I'm sure.

Change directory - In the file explorer, the file is located in /home/Downloads.

So tried to change the directory in terminal using cd

cd /home/Downloads

"NO Directory Exists"

so then tried

cd /home

No problems.

What the heck is the voo-doo-syntax that is preventing terminal from changing directory into the downloads folder?

Thanks!

After receiving a system wide software update suddenly printing services are not available. At this point, cups appears to be unable to run.

cupsd -t shows an error for

unknown directive JobPrivateAccess on line 137 of /etc/cups/cupsd.conf

By commenting out four lines and restarting cups, my print services seem to be running normally. Those four line have to do with JobPrivateAccess/Values and SubscriptionPrivateAccess/Values all four being set to default

cups-config --version responds with

2.4.7

What happened? Also What have I done by commenting those four lines? Is there a more appropriate correction for those four offending lines?

I provide remote computer support for an elderly parent, so it's very important that things change as little as possible from what they're used to.

I need to increase the size of the icons on the top bar of the display (mic, volume, login/restart).

Right now the dock panel is on the left and it needs to stay on the left. And I don't want to add any icons to it (such as by merging it with the top bar). Unless I'm missing something, this rules out the Dock To Panel GNOME extension.

I simply want to roughly double the size of the top bar icons. (Desktop icons and such have already been taken care of.)

I had download big files, hard drive partition become full, at the startup Ubuntu 24.04 says: [FAILED] Failed to start gdm.service - Gnome Display Manager

What can I do to repair my Ubuntu?

I used ssh -X in 16.04. Since being both local & remote 22.04 Wayland, there is no hit with wayland keyword search in ssh nor sshd manuals. I have Xwayland installed on each end. I get this error after I connect with ssh or ssh -X:

gedit&
[1] 27111
me@remote:~$ 
(gedit:27111): dbind-WARNING **: 14:35:14.547: Couldn't register with accessibility bus:
 Did not receive a reply. Possible causes include: the remote application did not send a reply,
  the message bus security policy blocked the reply, the reply timeout expired,
  or the network connection was broken.

I believe this is related to X11 being replaced with Wayland because ssh -X stands for enable X11 forwarding, but revert 22.04 to Xorg as advised around the web or downgrade to 16.04 I'd rather like not.

Please what is the new way ? Many thanks.

[EDIT] I checked with Graham's advice below but this made no difference (both remote & local sessions were/are Wayland)

[EDIT 2023/12] @ændrük, this post (17.10) was somewhat old since we use 22.04. Since my own post here (this very one), I only reached to get a remote GUI by using RDP :-)

A above, my remote device is saying the modem cannot be found, BUT I am can log in over a 4g network. The command mmcli -m 0 was working before and then I locked my modem to 4g, now its saying; "error: couldn't find modem"

My question is, how can I have it display the mmcli -m 0 output again?

I have been trying to make an Unbuntu 22.04 ROS2 Humble catkin workspace, but I have been unable to resolve the two command not found errors. Trying to reinstall the catkin package has not been much help either. I think catkin and catkin-tools are probably already installed anyway. I thought maybe it was a search PATH issue but not sure. As the code below shows, setup.bash is called by .bashrc to prepare the Env variables. I do not understand the command not found errors, but I need to resolve them. Please assist me if you can.

/home/.bashrc {this file (.bashrc) was edited so it includes line below

Question is different from mysql-server-8.0 installation problem on Ubuntu 20.04 because I absolutely cannot install mysql-server. He managed to install it. And my package manager broke on installing it, so I can't install or remove anything now.

I have recently installed Ubuntu 16.04 .and my networking settings are Proxy oriented. I added IPv4 settings and saved them but when I see the added IPv4 settings again, the subnetmask settings are not saved as I entered. In the place of subnetmask (255.255.252.0) a default number 22 is saved as show in the image below.

I don't know why that number has been appearing again and again even after saving required IPv4 settings.

I have a folder of large files. I want that folder to be in two different places at once - my Home documents, and my College documents folder.

I've done this with a symlink in the College folder to the Home folder.

Unfortunately, Dropbox syncs my College folder - and my file space was quickly used up.

Does dropbox follow hard links, and if so, how do I create one?

I followed the first answer here: How do I get an XBOX 360 controller working?, and ended up screwing with my XPad drivers. How can I reverse all of the commands and restore my XPad Driver?

I used these commands:

sudo apt-get install --install-recommends jstest* joystick xboxdrv
echo "blacklist xpad" | sudo tee -a /etc/modprobe.d/blacklist.conf
sudo rmmod xpad  # unload module if already loaded
xboxdrv --silent
jstest-gtk

Then I edited /etc/init/xboxdrv.conf and added

start on filesystem
exec xboxdrv -D
expect fork
