I'm running Ubuntu 24.04.3 with Gnome 46.0 and need to have app windows maximized on launch. I tried One Window Wonderland (https://extensions.gnome.org/extension/5696/one-window-wonderland/) Gnome extension, but it doesn't work (https://github.com/jqno/gnome-one-window-wonderland/issues/12). Are there any other working alternatives? If not, are there any other desktops with this functionality?

I really enjoyed to make budgie as daily OS! there's some problem with apps compability after migrated from windows 11 but it's fine. One case, i need to make my 'explorer' get gaussian blur. I've alredy done this at Windows 11, so i guess there's a better ways since i am using ubuntu budgie isn't?

So please i need help, thank you

I'm a newbie in Linux and I want to try Ubuntu in my laptop. However, when I start Ubuntu, it show the loading screen then lots of text with a dark background. The last line being:

The problem I faced is something similar to this while live booting into my old hp laptop. I've tried other solutions like removing quiet splash but all it does is showing status of successful or fail processes. How to solve this?

The laptop spec:

CPU: Intel(R) Core(TM) i7-6500U CPU @ 2.50 GHz
Memory: 12 GB of DDR4 RAM
GPU 1: Intel(R) HD Graphics 520
GPU 2: NVIDIA Geforce 940MX

I've attached the log fie, hope this might be useful.

Thanks

Sequence of events:

1. Clean installation of Ubuntu 24.04.3 on AMD CPU and NVIDIA Geforce RTX 3050 GPU, default options, except selecting proprietary drivers, which installed nvidia-firmware-580-580.95.05
2. System works fine, all packages are up-to-date.
3. Installed several applications, everything works fine, no system files update noticed.
4. Installed more applications, no system files update noticed.
5. One day from original installation, system boots to black screen with a cursor.
6. Rebooted in safe mode and sudo ubuntu-drivers autoinstall, which downgraded Nvidia driver to nvidia-firmware-570-570.195.03
7. System boots to black screen with a cursor.
8. Rebooted in safe mode and sudo apt install xserver-xorg-video-nouveau, which didn't install anything, but changed some settings.
9. System works normally.

Can you explain what happened? Why it suddenly stopped working without explicit system files update? Is there any drawback in using an older driver, e.g. CUDA performance?

Here is my current driver info:

This is probably a more informative current driver description:

I'd like to make a "live DVD" Ubuntu, but the latest ISO is too big for a DVD. Is there a cut down version that has the latest version, but is cut down to fit on a DVD?

Or, what was the last ISO version that would still fit on a DVD?

I've tried using Rufus to put the latest ISO on a USB Flash device and that boots up on my desktop happily. However, when I try it on my laptop, it doesn't recognize it as a boot device. I do know the laptop will recognize bootable DVDs because I do remember trying an old Ubuntu DVD a while ago. (I've since lost that copy.)

I just installed 24.04 on a B850 with a Ryzen 7 7700. Loaded Ubuntu fine, but now can't find the internet. Tried suggestions in help.....no help. I am coming from Win 7 Pro, and don't know command line. Thank you.

I bought an Anker Soundcore 2 bluetooth speaker.

Initial setup worked, the device was recognized by Blueman (after a bit of fiddling) and paired.

After a few hours of trouble-free sound and operation, the connection suddenly dropped and I got this message:

Connection failed: br-connection-page-timeout

I've tried:

* Disabling and re-enabling Bluetooth.

* Running `systemctl restart bluetooth.service`

* Manually removing the device from Blueman in the hope of reconnecting it.

Now, Blueman doesn't even find the active Soundcore 2 when searching; the field remains empty.

On my phone, I can easily find the Soundcore 2 as a Bluetooth device and connect to it.

Does anyone have any idea what the problem could be on Lubuntu 24.04?

Thanks in advance!

Can I get some assistance with getting my MacBook Pro internal speakers working? Sound plays fine through my Bluetooth headphones.

I just got a new PC and installed dual boot Windows and Ubuntu 24.04. Everything seemed to be going well until I got some disk space issues. I tracked this down to /var/log syslog . and kern.log which are showing the following issues:

syslog:

Initially both logs were up to 45gb each, resulting in Ubuntu not being able to boot up. Journal logs are also fairly sizable at 4GB, but less of an immediate issue. Syslog and kern.log are still both creeping up in size, but I've cleared them with:

sudo sh -c 'echo > /var/log/syslog'

sudo sh -c 'echo > /var/log/kern.log'

I'm aware this is only temporarily keeping things going. I've looked into logrotate and may set that up, but it seems that there's a broader issue with "pcieport 0000:00:1c.0: AER". I don't know what this is though or have any idea of how to fix it.

Is anyone able to help me with this? My command line skills aren't great and I don't really have and understanding of what's going on with these processes other than something with pcieport is throwing up unresolved errors and they're building up and taking over memory that I want to use for other things.

I'd really appreciate any clear advice, explanations or solutions.

I haven't run memtest that's linked, but I did run the one in BIOS settings and that showed no issues.

EDIT Memory card shows DX16GDDR4AA3200 16GB DDR4 PC-4-2PC4-25600AA-3200MHz

Memory card brand is 'XUM' which isn't on the Asus memory/device support list. It seems to be a UK based manufacturer with production in China, also trading as 'Dr Memory', upcycling chips from electronic waste sources https://www.scaleupinstitute.org.uk/stories/xum/

I installed dkms and ran it, but it returned nothing, so I take it that means I don't have it.

My wifi keeps disconnecting and reconnecting at random. I've tried many things to fix it. My wifi adapter is:

62:00.0 Network controller: MEDIATEK Corp. MT7922 802.11ax PCI Express Wireless Network Adapter (rev 02)

It seems to be connected to suspending the system when the lid is closed. Sometimes it will just gradually lose more and more wifi detections around me until only my home wifi is left, then when I suspend it, nothing is there at all.

So far, I've tried:

1. Using sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf, changing wifi.powersave to 0 and 2, with no success.

2. A script I found online:

#!/bin/bash

# Function to set power save for a given interface
set_power_save() {
    local interface=$1
    local state=$2
    echo "Setting power save to $state for $interface..."
    
    if sudo iw dev $interface set power_save $state; then
        echo "Power save set to $state for $interface using iw command."
    else
        echo "Failed to set power save using iw command. Please check your permissions or wireless interface status."
        return 1
    fi
}

# Function to get and display power save status
get_power_save_status() {
    local interface=$1
    local status=$(iw dev $interface get power_save | awk '{print $3}')
    echo -n "$interface: Power save: "
    if [ "$status" = "on" ]; then
        echo "on"
    elif [ "$status" = "off" ]; then
        echo "off"
    else
        echo "unknown (raw output: $status)"
    fi
}

# Function to make changes persistent
make_persistent() {
    local state=$1
    echo "Making power save settings persistent..."
    
    # Create a script to be executed by the service
    cat << EOF | sudo tee /usr/local/bin/set-wifi-power-save.sh > /dev/null

    iw dev \$interface set power_save $state
    echo "Set power_save $state for \$interface"
done

echo "Changes should persist across reboots."
echo "You can check the status of the persistent service with: sudo systemctl status wifi-power-save.service"
echo "If issues persist, check the system logs with: sudo journalctl -u wifi-power-save.service"

I since disabled this script''s effects after it caused issues switching from network to network and made network discovery impossible after toggling wifi with:

sudo systemctl disable wifi-power-save.service

sudo systemctl stop wifi-power-save.service

sudo rm /etc/systemd/system/wifi-power-save.service

sudo rm /usr/local/bin/set-wifi-power-save.sh

sudo systemctl daemon-reload  
  

3. I tried switching to ipv6 only from the network settings, which seemed to work, but it's hard to tell given the randomness of the disconnections. It's also just not sustainable.

4. I tried forgetting and re-adding the wifi, and the issues eventually continued.

5. I heard that messing with the kernel might fix it, but this also doesn't seem like a sustainable solution and typically applies to older wifi cards, where this laptop is a higher end modern model.

6. I've settled at the moment with leaving powersave-on.conf set to 3 and just doing ipv4 only, but again, this is likely not sustainable long term.

7. The issue had oddly stopped occurring with both ipv4 and ipv6 enabled. I renamed the SSID to something else, then went to saved networks in wifi settings and forgot them all, then rebooted and re-added the network. There were no disconnects for about a day before it started back up. All settings are more or less unchanged otherwise, including power saving. I also ran some commands to clear out some network settings before it resolved. I created this shell script to automate the process in future, also including instructions to navigate to settings to clear saved networks before rebooting, however, it should be noted that this is apparently a limited solution:

#!/usr/bin/env bash

set -e

echo "Stopping NetworkManager..."
sudo systemctl stop NetworkManager

echo "Removing NetworkManager system connections..."
sudo rm -rf /etc/NetworkManager/system-connections/*

echo "Removing NetworkManager state files..."
sudo rm -rf /var/lib/NetworkManager/*

echo "Removing wpa_supplicant state..."
sudo rm -rf /var/lib/wpa_supplicant/*

echo "Removing user NetworkManager cache..."
rm -rf "$HOME/.cache/NetworkManager"

echo "Starting NetworkManager..."
sudo systemctl start NetworkManager

echo "Go to WiFi settings -> Saved Networks, and remove all networks."
read -rp "Press Enter to reboot."

echo "Rebooting system..."
sudo reboot

8. Trying a slight modification of the last script, simply adding the powersave change and removing the known wifi networks before doing anything else. Same result. Works at first, but inevitably fails.

#!/usr/bin/env bash

set -euo pipefail

CONF="/etc/NetworkManager/conf.d/default-wifi-powersave-on.conf"

read -rp "Go to WiFi settings -> Saved Networks, and remove all networks. Then press enter to continue. The system will reboot when completed."

echo "Setting wifi.powersave = 2."

# Ensure config directory exists
sudo install -d -m 0755 /etc/NetworkManager/conf.d

# Ensure file exists without overwriting
sudo touch "$CONF"

# Update only the wifi.powersave line, or append if missing
if sudo grep -Eq '^[[:space:]]*wifi[.]powersave[[:space:]]*=' "$CONF"; then
  sudo sed -i -E 's/^([[:space:]]*wifi[.]powersave[[:space:]]*=[[:space:]]*).*/\12/' "$CONF"
else
  echo "wifi.powersave = 2" | sudo tee -a "$CONF" >/dev/null
fi

echo "Stopping NetworkManager..."
sudo systemctl stop NetworkManager

echo "Removing NetworkManager system connections..."
sudo rm -rf /etc/NetworkManager/system-connections/*

echo "Removing NetworkManager state files..."
sudo rm -rf /var/lib/NetworkManager/*

echo "Removing NetworkManager runtime files..."
sudo rm -rf /run/NetworkManager/*

echo "Removing DHCP lease files..."
sudo rm -rf /var/lib/dhcp/*

echo "Removing wpa_supplicant state..."
sudo rm -rf /var/lib/wpa_supplicant/*

echo "Removing Wi-Fi regulatory cache..."
sudo rm -rf /var/lib/crda/* || true

echo "Removing user NetworkManager cache..."
rm -rf "$HOME/.cache/NetworkManager"

echo "Flushing DNS cache..."
sudo resolvectl flush-caches || true

sudo systemctl start NetworkManager

echo "Rebooting system..."
sudo reboot

9. Upgraded the kernel to the newest 6.18.1. I upgraded using Mainline, installed with:

sudo add-apt-repository ppa:cappelikan/ppa
sudo apt update
sudo apt install mainline

However, the problem quickly returned.

10. Reinstalled the OS. Still occurs. Also ruled out the Connectivity Checking setting.
11. Running out of things it could be outside of Ubuntu itself. Starting to consider it may relate to VPN settings. The wifi itself would disconnect typically, which is why it wasn't considered previously. The same VPN also works fine on two other PCs I have running Ubuntu. May potentially relate to the VPN connecting initially with the DAITA setting without supplying a registered VPN connection (i.e. when Ubuntu shows the VPN toggle in the top bar). The previous installation on this PC never had the VPN active without DAITA, which may have been different than the other PCs. Update, didn't work.
12. Tried editing /etc/default/grub to include pcie_aspm=off in the GRUB_CMDLINE_LINUX_DEFAULT line. Breaks the wifi even more extensively.
13. Tried Ubuntu LTS. Same issues. I hope this gets fixed soon.
14. Switching to iwd after a fresh install fixed it, but caused other issues.
15. Switched to Zorin. Bye.

I did a reboot after each fix attempt. This is extremely frustrating. I have no idea what's left to try. Can anyone please help?

I’m running Ubuntu 22.04 on my ASUS Zephyrus G14 with a Realtek ALC285 sound card. My built-in speaker sound is high-pitched and kinda robotic. Sound through HDMI works correctly. Some things I've tried are changing the sample rate, different alsa model overrides, overriding the speaker mapping with hdajackretask, increasing volume, increasing base volume with an equalizer.

Has anyone gotten the sound to work well?

I ran the wireless-info script, the dmesg file contains periodic messages every few minutes about the wifi disconnecting and reconnecting. What can I do? I am on a Lenovo W510 which was solid as a rock under 18.04 LTS.

I recently shifted from windows(Laptop HP-15da1058TU Intel core i5 8th Gen) to ubuntu 20.04 but I'm not able use my touchpad in similar fashion (specifically zoom in, zoom out and 3 finger screen movement gesture)

While this link says, I can https://help.ubuntu.com/stable/ubuntu-help/touchscreen-gestures.html.en

So, can anyone help me set it up. Thanks in advance!!

I am using Ubuntu 18.04 and I want to delete files on another drive that has Windows installed.

Since I am using a dual boot setup, my Windows crashed two days ago. I installed a fresh version of Windows, which took over an hour. Now loading Windows is very slow and accessing files is also extremely slow. I suspect that the HDD is failing.

The HDD is 500 GB, consisting of two NTFS partitions (60 GB and 200 GB) and one Ubuntu partition (200 GB, which is not NTFS).

Windows was originally on the 60 GB partition, which is no longer accessible. Consequently I installed a fresh copy of Windows on the 200 GB NTFS partition, but it is running very slowly as mentioned earlier.

The strange thing is that Ubuntu loads normally and file access within Ubuntu is also normal. I can even access the files on the 60 GB partition easily (which is impossible while using Windows).

Does anyone know what the reason might be, and how I can delete files from that 60 GB partition while using Ubuntu?

From this link and this link, it seems I may get the chance to recover the data using Ubuntu Live CD.
So I download the Ubuntu iso file and burn it to a blank DVD.

After I boot from the Live CD, I use the "Try Ubuntu" option, but the raw drive is not listed in "Files" directory as seen below :

After playing around what is inside the Ubuntu desktop, I found a "Disks" icon, so I double click it and it show the raw drive (orange highlighted) :
.

Based from reading in the internet, I open the terminal window and type sudo fdisk -l, and the result is below :

with red text "partition 1 does not start on physical sector boundary" at the bottom.

The CrystalDisk information result show like below:

I need help from the experts if there is a way to have Ubuntu read the raw hard drive and explore it so I can copy it to another hard drive.

Any kind of respond would be greatly appreciated.
Thank you in advanced.

PS : Sorry I forgot to mention that I've tried TestDisk from Windows 10. But it seems there is something wrong with the drive which cause it became so hot after about 3 hours of Deeper Search. So I stop it. I post this "hot" problem in the Super User SE.

So I've recently started a new Minecraft server. and it works just fine locally and from another desktop (connected with the ip4) however. When I try to connect with the public IP address + port (example) 165.242.53.1:25565 it doesn't show.

I'm sure that I port forwarded well (I already ran a Minecraft server several times on windows) but I just can't figure out why it doesn't work.

I'm on Ubuntu 18.04 I believe.

I apologize immediately for my English

After buying a new notebook, Acer aspire A514-52-59EQ, with pre-installed Windows 10 home I wanted to go back to my dear old Ubuntu, in the new version 20.04LTS, specific that I have already tried with Ubuntu18.04 LTS, 19.10 and other various distributions Linux.

I have obviously disabled secure boot and quick start of windows.

During the installation, however, the warning of incompatibility with intel RST appears.Following the guide to which the warning refers, a request is made to change the SATA mode in AHCI from the Uefi Bios.

The problem is that inside the BIOS my SATA device is in "optane whitout raid" mode, but in the itntel optane app this is disable, and I cannot modify it in any way.

My storage controller is Intel SATA / Pcle RST premium controller chipset. Intel told me to uninstall it quietly, although I was doubtful that it managed the disk, I ignorantly trusted, I did it and the only thing that caused it was the inability to access the disk resulting in the necessary restore.

Instead, by contacting the Acer, they was told me that it is possible to create a Live USB in order to overcome the problem, but that since it was not their responsibility, we could not say more.

Can someone help me?

Thank you

I'm following this ISCSI guide here:

https://help.ubuntu.com/lts/serverguide/iscsi-initiator.html

At the bottom it mentions sdb is the new iSCSI disk however in the next commands it uses sbd1.

Why is this? Is this just a typo?

I am trying to connect to a my SSH server (running on Ubuntu 16.04.2 LTS) from my local machine (Ubuntu 18.04.03 LTS).

I have created a private and public key on my local machine and copied my public key to my SSH server's authorized_keys file.

I could log in with ssh root@ip-address and I have access (as root user), but when I tried to log in as another user with command ssh name@ip-address, it generated an error message:

name@ip_address: Permission denied (publickey)

What can I do so the name@ip-address could be accessed?

I am using the Ubuntu on Windows App running on Windows Subsystem for Linux. So an initial question is if Python virtual environments is supported. Given my as yet limited understanding of Python virtual environments I would think that they are supported in the Ubuntu on Windows App. Here is the version info:

Windows Ubuntu App 1804.2019.521.0

Ubuntu release 18.04 (bionic)

Python Version 3.6.7 (as best I remember this was installed by default).

My motivation for wanting to use venv is this reddit post:

venv by nature of being part of Python itself has access to the internals of Python which means it can do things the right way with far fewer hacks... ...So venv can be thought of virtualenv done right, with the blessing and support of the Python developers.

Similar questions came up when I entered my question, but I didn't find one that solved my problem.

One post:

Since you specifically installed python3.6 instead of Ubuntu's default python3 version, which is python3.5, you have to install python3.6-venv instead of python3-venv since that would resolve to python3.5-venv. To do so, you can use sudo apt install python3.6-venv

Another post from 01/2018 said that python3.6 -m venv myvenv worked after reinstalling Python3.6.4. I'm avoiding re-installation for the time being.

Here is what I tried to create a virtual environment:

1) Opened Ubuntu

2) Went to the directory where I want to create the virtual environment.

 /home/dgrucza/python-virtual-environments

3) Entered python3 -m venv env This returned the following:

The virtual environment was not created successfully because ensurepip is not available. On Debian/Ubuntu systems, you need to install the python3-venv package using the following command.

apt-get install python3-venv

You may need to use sudo with that command. After installing the python3-venv package, recreate your virtual environment.

Failing command: ['/home/dgrucza/python-virtual-environments/evn/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']

4)Tried to install venv by entering sudo apt-get install python-venv After entering my password at the prompt this returned the following:

Reading package lists... Done Building dependency tree Reading state information... Done Package python3-venv is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source

E: Package 'python3-venv' has no installation candidate

5) Also tried entering python3.6 -m venv myenv, but received the same message.

The virtual environment was not created successfully because ensurepip is not available. On Debian/Ubuntu systems, you need to install the python3-venv package using the following command.

apt-get install python3-venv

You may need to use sudo with that command. After installing the python3-venv package, recreate your virtual environment.

Failing command: ['/home/dgrucza/myenv/bin/python3.6', '-Im', 'ensurepip', '--upgrade', '--default-pip']

I am trying to upgrade from Ubuntu 16.10 to Ubuntu 18.04 and getting this error everytime:

An upgrade from 'yakkety' to 'bionic' is not supported with this tool.

How do I resolve this?

err:module:import_dll Library mfc140u.dll (which is needed by L"C:\Program Files (x86)\GOG Galaxy\GalaxyClient.exe") not found

err:module:LdrInitializeThunk Main exe initialization for L"C:\Program Files (x86)\GOG Galaxy\GalaxyClient.exe" failed, status c0000135

I have ran vcrun2015 using winetricks and I still get that error, and that seems to be the only fix I could find online. Any help would be very very appreciated, I've been trying to solve this for 12 hours :'(. Please keep it noob friendly as I have just started using Ubuntu.

Thanks,

I have done an RMI scan, and I wonder if it's possible to open DICOM files, to see it. Ubuntu recommended I install ImageJ, but that didn't decode it or whatever.

A friend of mine opened it with Photoshop and seems like it worked, but I need a program I can easily use on Ubuntu.

Looks like Ubuntu Tweak project is no longer maintained and the application is no longer available through PPA. I particularly loved the Janitor feature in Ubuntu Tweak. Are there any alternatives one can use?

I'm a new user banging my head against the wall trying to get my Wacom tablets to work on Kubuntu 14.04. I have two tablets: a bigger, older Intuos 2, and a smaller, much newer Intuos Pen Small. I tried following all the guides I could find on here and the Wacom Linux Project wiki, but I couldn't get my Intuos 2 to work at all.

After a while, I decided to see if my Intuos Pen Small would work out of the box, as some other forum goers have mentioned. When I plug it in, I immediately get cursor functionality, however I can't change any settings. In the Graphic Tablet - KDE Control Module window, I get an error saying "Graphic Tablet Error: Profile Default Does Not Exist". If I try to make a new profile, it gives me the same error, replacing the above "Default" with whatever I tried to name it.

I'm thinking maybe, somewhere on the long winding path I took trying to get my old Intuos 2 working, I messed something up. I want to try reinstalling everything all over from scratch. Unfortunately, I don't really know where to start, and I can't find any guides for this online. Please help, thanks!

I've Xbuntu installed on a 128GB SSD that boots and runs without issue on my desktop. (Even on its own with all other drives disconnected) When placed in my laptop, although it sees the disk, I receive an "Operating System not Found" error during boot. I have tried the steps outlined in this similar post:

Ubuntu 14.04 Installation on Fujitsu Siemens Notebook - Operating System not found notebook-operating-system-not-fou

Step 5 did not provide this option - only the default recommended repair which I did.

Below is the output of my boot-repair dump. I've run the repair but it has not been successful in resolving the issue. My Home partition is encrypted.There is / was no dual booting of any kind going on. Any suggestions very much appreciated, thanks.

I downloaded centos everything ISO which about 6.4GB in size however I could not write that ISO file onto a DVD using k3b tool as it is showing Blank dvd doesn't have enough space. I want to dual boot my computer one with Ubuntu and another one with Centos, For installing CENTOS i need to write that everything ISO on to the DVD which is of 4.7 GB in capacity and then go for installation.

How should i ?
