I am currently using Kubuntu 25.10.

The problem is that when I turn on Wi-Fi and connect to a Wi-Fi network, after 2–5–10–15 (random) minutes, my system freezes (keyboard + touchpad + mouse + screen) with a fullscreen message "KERNEL PANIC", and then I have to force shutdown to restart the system.

So I thought there was a problem with Kubuntu 25.10. Then I tried using the latest Linux Mint (through a live USB) without connecting to a Wi-Fi network, and the moment I tried to connect to a Wi-Fi network, the system froze again. Then I became sure that the issue is not with Kubuntu 25.10.

So now I am still using Kubuntu 25.10 and using the internet with USB tethering through my mobile phone, and the issue is gone. I haven’t checked with Ethernet. So if I unplug the USB cable and turn on Wi-Fi, it automatically connects to an available network, and I can use the internet for a maximum of 2–5 minutes. Then the Wi-Fi automatically disconnects, but in the panel (Wi-Fi connected icon) it still looks like it is connected, and then the system freezes, displaying a message: “KERNEL PANIC.”

There are some outputs of useful commands:

I installed an Virtual Maschine Manager but ein got no connection to Qemu. I got the message that I should look, if a adequate libvirt daemon is running. What could I do? This is the full message:

Verify that an appropriate libvirt daemon is running.

Libvirt URI is: qemu:///system

I'm running Ubuntu in a VmWare VM. I have eliminated all snapshots and increased the size of the disk in the VM. What do I need to do to use the additional space?

I've got bind9 installed and it's working just fine. All nslookup and dig commands work, checkconfig all of that.

I just want any unresolvable requests to go to Google. Here's /etc/bind/named.conf.options:

options {
    directory "/var/cache/bind";
        forwarders {
            8.8.8.8;
        };
    dnssec-validation auto;
    listen-on-v6 { any; };
};

I'm not sure what else I need to do.

The requests are not sent to 8.8.8.8. I verified that in Wireshark.

Authentication Prompts to Install Unknown Software:

An icon appears on my hotbar (KDE/Kubuntu) when I first log in after rebooting my computer. It looks like a speech bubble with an ellipsis in it. Clicking on this brings up this pop-up asking for authentication to install... something. I have no idea what it is, but have been worried it might be malware (thus I always cancel, and it goes away). I've been using Kubuntu for several years, and Linux for longer, but have never seen anything like this. It doesn't seem related to Dolphin or the normal updates.

Does anyone know what it is? If it is a threat, anyone know how to get rid of it (I'm tired of seeing it every time I restart my computer)?

I am currently developing a Web API using ASP.NET Core with Entity Framework Core and SQL Server. It runs perfectly well with a couple of users, but when more than one request comes into the system simultaneously, its performance degrades drastically.

Below is a sample of the code I have written:

public async Task<IActionResult> GetUsers()
{
    var users = await _context.Users.ToListAsync();
    return Ok(users);
}

Environmental Information:

• ASP.NET Core 7
• Entity Framework Core
• SQL Server
• Approximately 50–100 simultaneous requests while testing

Issue: As the number of simultaneous requests grows, response time is incredibly slow and CPU utilization increases. At times, requests are timed out.

My Attempts at Solution:

• Examined database indexes
• Enabled logging for tracking query
• processing Performed testing using small data

sets

Query: What might be the reason for this issue during simultaneous requests, and what measures can be taken to enhance performance in such a situation?

Can anyone recommend some good disk data recovery software for Linux? I have a 4 Tb disk that was my primary Ubuntu 22.04 drive about 3/4 full that has a damaged GRUB and wouldn't boot. I spent about 2 weeks trying every repair command line strategy Google could come up with without any success. As a last resort I re-installed Grub from the installation USB. Now it boots but doesn't access any of the 257,410 items that 'properties' describes as unavailable. I presume that means I have overwritten some or all of my root directory. I have a new installation of Ubuntu 24.04 on a different computer with a larger drive so I have a safe place to put any recovered files. All the recovery software that Google comes up with seems to be for Mac and Windows and runs on Mac or Windows. I have 5 different flavors of Linux but no Mac or Windows. Any suggestions would be welcome.

User68187 asked what flavors of Linux. Ubuntu22.04 and 24.04, Mint 22, and LMDE7; all in desktop PC's. LinuxCNC (Debian 14) and BeagleBone black (Debian 12.13),in two dedicated non-PC machine controllers.

I am about 3-4 weeks new to Ubuntu, downloading it in a bid to not install Windows 11, and for those weeks I've been trying my hardest to get my Steam games working on this device, to no avail.

Some games do work. I was able to get PEAK working on my computer after a LOT of setup, and single player games/really old point and clicks (e.g. Dave the Diver, Sam and Max Hit the Road, IHNMAIMS) work perfectly (though this could just be because of how simplistic they are).

Games such as Deadlock, Marvel Rivals, and The Outlast Trials, more high-fidelity games with a high amount of multiplayer however don't boot up. The best I've gotten is Deadlock, which I've been able to get the launch screen up until it crashes. Unfortunately all the answers I've seen on this website are either not working, or are simply too complex for my newbie brain to comprehend. I have gamemode installed and configured, GeProton is installed and applied to all desired games, ProtonTricks is installed, though I have no idea idea how to use it, and my Driver package is nvidia-driver-535.

Here is the last terminal log I recorded with Deadlock, gained by running Steam through Terminal. If I had to guess what the problem was, it would be the system is not recognizing libgamemode.so, despite it being on the device.

Please help me with this. I'm at my wits end, am not going back to Windows for the life of me, and I not really welcome to the idea of booting another OS such as Arch and drafting all my files to that system just to have a better chance. It's already been a pain in the ass just to get Ubuntu working.

I use KDE Connect between my phone and laptop on my University WiFi. Very often, the IP address changes and the connection stops working. I have to manually find the IP of the computer with the command ip address and put it in my phone and connect manually. The same thing happens when I connect to a different network.

Is there any way to automate the connection process? AFAIK know Apple's computers have some robust connection procedure with iOS devices.

I want to be able to do this for multiple computers with the same phone.

I'm using Ubuntu 24.04 LTS, and everything was working fine until a recent system update.

After updating, I started noticing:

• System feels very slow (apps take longer to open)
• High CPU usage even when idle
• Occasional lag/freezing

I already tried:

• Restarting the system
• Running sudo apt update && sudo apt upgrade
• Checking running processes with top

...but the issue is still there.

Is this related to a recent kernel/update issue? How can I diagnose and fix this properly?

Cannot get security updates. This is the message i got

I have a Lenovo IdeaPad Slim 5 16HAP9 that is running Ubuntu 24.04.3 LTS. With some regularity the track pad will partially stop working. The symptoms are not always the same but commonly include inability to left or right click, loss of 2 finger scroll, and increased cursor sensitivity (moves much faster). I can always move the cursor and sometimes left mouse click still works. The laptop has a touch screen which continues to function properly.

If I reboot the track pad will continue working for some indeterminate amount of time before the issues reappear. I have not found a predictable cause. It seems very random.

I can also get the track pad to work again by reloading the driver.

sudo rmmod hid_multitouch
sudo modprobe hid_multitouch

Are there ways to find errors or log messages that can give me some hint as to what is causing the issues and how to fix it?

I am using ubuntu24.04.2, and suddenly wifi, bluetooth, and screen brightness disappeared from the icons in the screen above right. And when I go to wifi or blutooth in settings, it tells me that wifi adapter and bluetooth not found. What may be the problem. NOTE: They were existent before, but they suddenly disappeared

On my lubuntu 24.04 distribution I have installed the hypervisor Oracle VirtualBox 7.1.6 and I have imported a Virtual Machine (called my-virtual-machine below in this question).

Start and Power Off a Virtual Machine by command lines

I have found how to start and power off a Virtual Machine by command line:

1. To start a Virtual Machine:

/usr/bin/VBoxManage startvm 'my-virtual-machine' --type gui

2. To power off a Virtual Machine:

/usr/bin/VBoxManage controlvm 'my-virtual-machine' acpipowerbutton

Descriptions of my needs

I have the following needs:

1. to start my-virtual-machine (the Guest) automatically at boot time of my Host (that is lubuntu 24.04)
2. to Power Off my-virtual-machine at the shutdown of the Host
3. the Virtual Machine must to be start with the GUI and not headless

By this post, which is very old and refers to VirtalBox 4.2 but seems yet valid for VirtualBox 7.1, I'm able to solve my first request and perhaps the second request.

The problem is the third request because the method explained by the post allows to start the virtual machine at boot of the Host system but in headless mode and not with the GUI. When the Vitual Machine is correctly started I can see the following 2 process by ps aux command:

> ps aux | grep VBox
[...] /usr/lib/virtualbox/VBoxHeadless --comment my-virtual-machine --startvm 546632bd-b8bd-4f2d-b2a1-8657b968378a --vrde config
[...] /usr/lib/virtualbox/VBoxSVC --auto-shutdown --inherit-startup-pipe 7

Question

How to start a Oracle VirtualBox VM with GUI (and not headless) at boot time of the Host system and power off the VM at the shutdown of the Host system?

I am experiencing an annoying scaling issue with LibreOffice, Calc, Writer, etc.

When I open any dialogue box for any settings box, the text is very large, and the box is too small. I can make the box bigger, but that is extremely annoying to have to do every time.

I am running Kubuntu 24.10 on Wayland.

Libre Office 24.8.4.2

After the upgrade I have noticed that dragging a file to WPS office window in order to open it leaves behind a ghost icon stuck on the screen above all windows:

Ghost icon:

Using nautilus -q solves the problem, but it is generally annoying and I have no clue how to debug this behavior.

##Please see output at this link https://termbin.com/nru6.

I have looked at https://github.com/lwfinger/rtw89 and tried it but it doesn't work. It also says this in the description.

"This code will build on any kernel 6.10 and newer as long as the distro has not modified any of the kernel APIs. IF YOU RUN UBUNTU, YOU CAN BE ASSURED THAT THE APIs HAVE CHANGED. NO, I WILL NOT MODIFY THE SOURCE FOR YOU. YOU ARE ON YOUR OWN!!!!!"

Any help will be appreciated. Thanks

I hope you can help me with an issue I've encountered recently.

Setup:

VM Software: VMware Workstation 17.5
Guest OS: Ubuntu 22.04.2
Host OS: Windows 11 22H2
Hardware: Intel CPU, NVIDIA GPU

Background: Everything was working fine until a few days ago.

The Problem: Recently, my Ubuntu VM started freezing intermittently. Here's what happens:

• I can move the cursor, but clicking anywhere doesn't have any effect.
• The keyboard becomes unresponsive and its lights turn off.
• Animations inside the VM, such as window movements and the clock updating, remain functional.
• I can still use CTRL + ALT to switch back to the host, which continues to work normally.
• In rare cases, if I wait for a while, the VM becomes responsive again. However, in most instances, I have to restart it. After a restart, it works fine for a bit but eventually runs into the same problem.

What I've Tried:

• I've searched various forums and tried suggestions such as enabling the enhanced keyboard feature, but it didn't help.
• I attempted to create a new VM from scratch, yet the issue persists.
• I've ensured that the VM has ample memory and threads allocated.

I'm not very knowledgeable about Ubuntu or VMs in general. Can someone guide me on how to solve this problem? What additional information do you need from me to assist further?

Thank you for your time and help!

Sometimes I need to edit files in /etc. I know I can do this with the console (sudo mv some/file /etc/some/file, sudo nano /etc/some/file) etc, but I find this way a bit clunky. Call me spoiled, but I'm really used to GUI tools such as Nautilus and Gedit.

Distributions such as Ubuntu Mate or Mint make it easy: I can right click a folder and then a context menu appears with options such as "open as administrator". From then double-clicking a text file opens it in gedit with elevated privileges.

However, I can't find such an option in the default Unity version of Ubuntu:

Note:

• I am aware of the question Ways to run Nautilus with elevated privileges , but the solution recommended here is to use gksudo, which no longer works
• I suppose I can always do sudo gedit /etc/whatever, but - AFAIK - using sudo with GUI tools is heavily ill-advised
• I recall some say that it is ill-advised to run GUI tools with elevated privileges at all. This doesn't seem to be the case, however, since some default GUI tools themselves ask for elevation, Ubuntu Software being perhaps one of the most prominent examples:

Is there a way to run Nautilus or Gedit with elevated privileges?

Online I found the following figure where you can see "CPU" as first row, and it should represent the total amount of the used CPU.

Amongst the options of the htop I run on my PC there isn't the above CPU option. Where can I find it?

I recently set up Ubuntu server 18.04 LTS on an old laptop to use as a Plex Media server, and wanted to connect it to my existing media share on my QNAP NAS. I set this up using CIFS, and it seems to work, but every now an then i get the following message appear on the screen.

CIFS VFS: Free previous auth_key.response = 0000000076b9d676

The number at the end always changes. How do I get rid of this message??

Btw here is how I setup access to the share

Install cifs-utils

sudo apt install cifs-utils

Create mount directory

sudo mkdir /mnt/nas_media

Create credentials file

cat > ~/.smbcredentials
username=myusername
password=mypassword
ctrl+c

sudo chown root ~/.smbcredentials
sudo chmod 600 ~/.smbcredentials

Get UID for plex user account

id -u plex

I'll be using 113 as the UID for this example

Backup fstab file

sudo cp /etc/fstab /etc/fstab-old

Add share to fstab

sudo vi /etc/fstab

press i to enter insert mode go to end of file and enter a new line add the following

Note ip, sharename and username have been changed for privacy. Also vers=3.0 was set because that is the version of samba I have set on my nas.

//192.168.1.50/MyShare /mnt/nas_media cifs vers=3.0,iocharset=utf8,credentials=/home/myusername/.smbcredentials,uid=113 0 0

type :wq to save and exit vi

Load the new mount point

mount -a

btw I've also rebooted the server and the message always comes back. Plex is able to read and write to the share, so I'm not too sure why this message is coming up.

Is there anything I missed?

I believe it's a big question among asus users, cause i've found tons of questions about "why do my backlight don't change with fn keys??".

Well... after to much researching and testing (I'm a linux noob btw :P), I found that the Fn keys change the value of the file /sys/class/backlight/asus_laptop/brightness. But, to change correctly the brightness, the file /sys/class/backlight/intel_backlight/brightness must be changed.

I even created a script to change it through bash, works alright and stuff... i just type ./brightness 50, where 50 means the % of the maximum brightness... but i still miss my Fn keys, for God's sake!!

Then I tried to simply change the symlinks that redirects the folders (asus_laptop and intel_backlight are symlinks to very opposed directions), but not even sudo was capable to change these symlinks...

In resume, I'm asking help to re-enable my Fn keys to work with the backlight brightness.

Thanks!

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

I am struggling to get this to work properly.

This works in terminal

sudo bindfs -u dave /media/dave/Documentary2Lin/RAIDMain/Documentary2 ~/shares/Documentary2

How do I get this to work in fstab?

I've tried

/media/dave/Documentary2Lin/RAIDMain/Documentary2 ~/shares/Documentary2 fuse.bindfs force-user=dave perms=a=rX 0 0

It gives an error in fstab

I need a TALK to TEXT program to speak to the computer and have it write my reports. I have problems with my wrist and can not type fast. I'm working with the Linux system. I need a link to install this also. please help i can't find what i need

I started with Linux a year ago. Few weeks ago it was my idea to install the EFISTUB bootloader.

I used an Live CD to freshly install 12.10, and studied the articles of http://www.rodsbooks.com/ inside out.

The problem I am facing is that few files need to be copied from sda2 (Ext) to sda1 (fat32). I can not find a way to do it?

I'm writing a simple bash script, but I need it to check whether it's being run as root or not. I know there's probably a very simple way to do that, but I have no idea how.

Just to be clear:
What's a simple way to write a script foo.sh, so that the command ./foo.sh outputs 0, and the command sudo ./foo.sh outputs 1?
