I recently installed Ubuntu 24.03.3 LTS on a new bought Lenovo IdeaPad 5 2-in-1 14IAL10, alongside Windows 11. Everything worked fine (except the Realtek sound card, but that's another issue) until after two days the bootloader didn't show up anymore. It's not listed in the bios either. The only option there is the Windows bootloader. I can still log in the Windows 11 partition, but not anymore into Ubuntu. With an Ubuntu live edition I downloaded "Boot repair" and got the report under https://paste.ubuntu.com/p/JhZQ9w8JSV/ Does anybody have an idea what to do? Thanks for input on the issue.

We currently are using a network booted PXE cloud-init based auto installations of Ubuntu 20.04 LTS that allow us to automate the installation of Ubuntu onto a number of workstations (if needed). In our environment, we also have a Microsoft SCCM server that automates the installation of Windows onto a number of workstations.

Right now, we have to keep these environments separated by VLANS & DHCP Scopes as the DHCP options that point to the TFTP server are different for Windows and Linux.

What I was wondering, is it possible to somehow combine these into a single PXE server giving us an option to image with Windows or Linux. Choosing the Windows option will boot into the WinPE environment needed to work with SCCM, and Choosing the Linux option will proceed with the Cloud-init autoinstall version of Ubuntu 20.04.

If this is possible, does anyone have a working version of a config file that they can share and maybe answer a few high level questions on what it is I need to configure in on PXE server to enable this?

I wanted to install Steam on my laptop with Ubuntu 24.04. I installed it via snap, but something went wrong, and I decided to reinstall Steam. While removing Steam the process got stuck and I closed the terminal and tried to remove Steam again, but I got an error snap "steam" has "remove-snap" change in progress. I tried snap abort 26 (Steam removing process), but after rebooting I got the same error.

I tried running systemctl list-units | grep snap.steam to find any related units, and tried stopping and disabling them, but that didn't work.

I also tried sudo snap refresh core, but that didn't work either.

I can connect to the internet through ethernet but I can't seem to find wi-fi connections, even though there is wifi in our home

this is the output of the wireless-info script I downloaded from another question a year ago

I just can't get it right, I've downloaded several different versions to make it work on 24.04.3 LTS, there are always three files related to wireless connexion that just won't work, and wpasupplicant is the only file with ii, I'm about to uninstall ubuntu 24.04.3 and I'd like to know which version I'll install instead. Everybody I know in life knows nothing about Linux, Ubuntu. Last time I had it running was back in 1999. Help me out if you can, please! Cheers!

xrandr: Output HDMI-0 is not disconnected but has no modes in the nvidia settings it gives me Aquire EDID option i have 3080 on 580 open driver and linux mint kernel 6.8.0-88- generic

I know, I read the reasoning, wayland is not xserver. But, window has process, once I have process i just kill -9 Why is it so difficult to get pid for a window? I still don't understand this. It seems to me that nobody pays any attention to this. We can submit bugs to ubuntu in a way normal user will never do. If we had feature requests with voting, we might already have wkill, working suspend, better type to search screen plus many small things we would not come to at all. feature requests with voting is something StackExchange might do for many projects...

I run more or less stock Ubuntu 22.04.5 LTS, using the default Gnome desktop.

Background:

When I start background processes from scripts or a terminal after logging in to Gnome, these are all owned by /lib/systemd/systemd --user process.

When I disconnect the GPU drivers and attach them to vfio-pci for passthrough reasons into a VM, the entire X session dies, which I don't think is strange since the monitor the session was displayed on is no longer available. When this happens, all processes owned by /lib/systemd/systemd --user are killed, which in most cases is not a problem.

However, this is a problem for (in my case) both tmux (run as my local user) and veracrypt (run as root), which are started by ~/.config/autostart/*.desktop files when my user logs in. I want both of these to remain running, so that subsequent logins or SSH sessions can access my mounted filesystems etc.

I also want those processes to keep running if I manually log out from a Gnome session, even if the entire desktop environment would remain up.

My issue is this:

How can I keep (in my case) tmux and veracrypt running after events described above, which I think means to have another process owner than the default /lib/systemd/systemd --user process? For examble the /sbin/init process (PID=1).

Edit: For example, when starting tmux for the first time after logging in via SSH, process 1 owns the tmux server process, even after starting other sessions from the terminal in my X session. That's what I'm after. That still leaves my veracrypt problem, though.

(Here is my due diligence: This seems relevant, but the "disown" bash command does not seem to work, since in my testing it did change process ownership to ´systemd´. I have not tried nohup, since I would need to apply it to a process started normally, and I have not found a way to use nohup in that way. This answer suggests it is not possible to change ownership after the process has been started (at least not from userspace), even though the kernel changes the PPID from (e.g.) a bash process to (e.g.) systemd process if a background task is started from a terminal, and then the terminal is killed.)

I am in Kubuntu 24.04 LTS and I am trying to get transparency+blur in Plasma 5.27, without success. Take for example the Gently theme, I have installed and selected the global theme, then the Kvantum theme. I have been sure that transparency for dolphin is selected in Kvantum Manager settings.

It should apparently look something like this:

But instead it looks like so:

But even that I can achieve only with a supplementary setting in Kvantum Manager to assign specific themes to specific applications - by re-assigning the same theme to Dolhin.

—otherwise, I get this color consistency:

The menus do have transparency and blur (that I'd like to see in Dolphin too), even without the "Translucency" desktop effect:

Is that because of the "Plasma Style" (plasmoid theme)?

What am I doing wrong?

I can add transparency per application with a window rule - special application setting (see menu option selected in previous image, followed by "Add property - Active opacity"), but that is not what I want: it is a forced, overall transparency without any blur, it makes even the folders and text transparent (and, with full transparency, invisible!) like so:

I have Ubuntu 24.04 on my work laptop and use Edge Apps for Outlook and Teams. (I use webapps because that is the only thing that works here and Edge because it has been configured for single sign on.)

This has worked fine, but since the end of last week, pressing F7 anywhere opens the Outlook App. I use Midnight commander extensively, so losing F7 is a problem. Moreover, I see that also F8 stopped working in the terminal, even if it does not seem to do anything else.

This happens even if I have no other Edge window open, so it looks like a system shortcut of some sort. I have looked at Edge settings, but did not find anything there.

How can remove/unregister this shortcut? And, more generally, is there a way of listing all active system-wide keyboard shortcuts?

We found that Server Port No. 4 (MAC Address: xx:xx:xx:xx ) of Adapter 1 – BCM 5719 1Gb 4p BASE-T OCP Adapter is not assigned to any bond at the OS level. The corresponding OS interface is ensxxx with IP: 172.30.x.x

However, despite this interface not being part of any active bond, we are consistently seeing RX Drops on this port. The average RX Drop percentage is approximately 34.9%, which is significantly high and concerning for us.

Below are the sample RX drop counters for your reference:

RX:  bytes     packets   errors   dropped   missed   mcast
     10792122  111580        0     38970        0    69041

RX:  bytes     packets   errors   dropped   missed   mcast
     10797523  111634        0     38988        0    69074

RX:  bytes     packets   errors   dropped   missed   mcast
     10799377  111654        0     38996        0    69086

RX:  bytes     packets   errors   dropped   missed   mcast
     10802518  111681        0     39006        0    69103

RX:  bytes     packets   errors   dropped   missed   mcast
     10818339  111846        0     39064        0    69206

kindly advice on this behavior and for next steps, as such a high RX drop rate is not acceptable for our environment.

Any suggestion on how to fix?

Previously the wireless card was detected and worked on Ubuntu 18, 20, and 22 LTS. 1-2 months ago they quit - likely after an improper shutdown, but it wasn't critical enough to fix at the time. I just upgraded to 24.04.3 LTS in hopes that would fix it, but it didn't.

Things I've checked:

• bios has the card enabled
• lshw shows the card
• Check for firmware updates, install b43 firmware, update with the bug (answered this question in the process)
• "Airplane mode" is off

Do I need to uninstall/purge and reinstall the b43 drivers?

If anyone can tell me what I need to do to restore the snapd system to operability, it would be appreciated.

deja-dup will not backup to my external FAT formatted hard-drive. My system is ubuntu 24.04.03 with no windows partition.

I have tried to change the permissions so that I am the owner with

sudo chown -R $USER:$USER /mnt/usb-Seagate_Backup+\_BL_NA751YCT-0:0-part1

but get the response

chown: changing ownership of '/mnt/usb-Seagate_Backup+\_BL_NA751YCT-0:0-part1': Operation not permitted

Please help ! Ubuntu version cat /etc/os-release PRETTY_NAME="Ubuntu 24.04.3 LTS"

A suggestion to use ext4 formatted hard drive instead of FAT . I have tried it but have exactly the same problem with permissions.

Can you write on it ? No , "Error while copying " "the folder be copied because you do not have permission" Error message given by deja-dup "Error creating directory /mnt/usb-Seagate_Backup+_BL_NA751YCT-0:0-part1/simon-peter-gough-ThinkPad-T14-Gen-1: Permission denied"

Suggestion by Rizwind: : For windows partitions permissions are set when mounting. But you -will- loose all permissions as set for the files if the backup is not tar'd. " I have tried it but have exactly the same problem with permissions." no you don't. You need to set the paritions to the use the backup program uses OR add yourself to its group and it will work

Thank you Rizwind. Sorry, I am a beginner. How do I "set the (partitions ?) to the use the backup program uses OR add yourself to its group "

I have a new Ubuntu install and a newly downloaded and expanded eclipse application. I put the following eclipse.desktop into ~/.local/share/applications:

[Desktop Entry]
Type=Application
Name=Eclipse
Comment=Eclipse IDE
Exec=/opt/eclipse/eclipse-java-2025-09-R-linux-gtk-x86_64/eclipse/eclipse  # Path to the Eclipse executable
Icon=/opt/eclipse/eclipse-java-2025-09-R-linux-gtk-x86_64/eclipse/icon.xpm # Path to the Eclipse icon file (often icon.xpm)
Terminal=false
Categories=Development;IDE;
StartupWMClass=Eclipse

When I use "Show Apps", I would like to be able to see Eclipse, preferably without searching for it. For now, I enter "eclipse" into the search field, and Eclipse shows up as an empty rectangle just below the search field. If I click on that, eclipse runs, but I was expecting the Eclipse icon in that rectangle.

I have read two other posts on Ask Ubuntu and tried suggestions from those. I have verified that icon.xpm is in the directory specified in the desktop file (i.e., in the directory with the executable). I have used find to verify that this is the only eclipse.desktop file on the disk. I have eliminated this desktop file and double-clicked on the executable from the Files application; Eclipse runs, but no eclipse.desktop file appears in ~/.local/share/applications or anywhere else.

Can someone help me figure out how to get the Eclipse icon working for the Show Apps app?

I am using Ubuntu 24.04 on my Dell XPS laptop. I am experiencing an issue where image previews (thumbnails) are not displayed on my desktop. Instead I see generic icons for image files:

Steps taken to troubleshoot:

1. Checked File Manager Settings:

   • I opened Files (Nautilus) and navigated to Preferences.
   • Under the Performance tab, I confirmed that the option to show thumbnails is set to All files.

I would appreciate any assistance in troubleshooting this issue further. Are there additional steps I might have missed, or is this a known issue with a specific fix?

I installed Wireshark in my Ubuntu for Windows WSL following these steps.
It's installed correctly as wireshark --help and wireshark --version work fine.

But upon running wireshark with command wireshark it throws an error: error can be seen here.

I tried solving it using answers from here, but installing Xming on my Windows system also didn't help. Or perhaps I am not doing it right way.

Please someone suggest some way.

Thanks.

I installed Ubuntu 18.04 on a new ASUS Zenbook recently and virtually everything works almost perfectly. With one exception: Suspend/Resume is broken. Ubuntu seems to be aware of that and by default, selects s2idle:

$ cat /sys/power/mem_sleep
[s2idle] deep

Of course, this means that the laptop's battery is down by about 30% after a day of sleep and it means that the laptop really isn't useful as the mobile device it's supposed to be. I can activate deep sleep by

$ echo deep > /sys/power/mem_sleep

And then the computer does suspend properly (for example via pm-suspend). I can see this because the power indicator LEDs on the side and in the power button start blinking slowly, in the same way as they do on my four-year-old Zenbook. If I wake the laptop up by pressing the power button briefly (or by opening the lid), the computer seems to start waking up (the power indicator LEDs go from blinking to steady light), but neither does the screen turn on, nor does the computer react to the keyboard in any way, nor can I ssh into it.

There are a couple of posts online that seem to find similar behavior with the nouveau driver for NVIDIA graphics cards. But neither does my computer have an NVIDIA card (it has a built-in Intel), nor does the nouveau driver accidentally get loaded.

Another set of online advice recommends using older/new kernels. I've tried kernel versions down to 4.14.41 and up to some 4.18 versions, both none of them changed this behavior.

I'm a little stumped here. I don't even know where to start diagnosing this. Any help would be greatly appreciated.

p.s. Hibernate doesn't work either, but I'm not overly eager to get it to work.

I have one 4K monitor (3840 x 2160) and two QHD monitors (2560 x 1440) and I want to have them side by side. This is currently not possible though, since the horizontal virtual resolution required for this is 8960 pixels (3840+2560+2560) but the maximum (horizontal) virtual resolution set by the X server is 8192 pixels. Is there any way to increase the maximum virtual resolution past 8192x8192 pixels?

What I have tried up to now:

• I do not have a xorg.conf file - I tried manually creating one myself including the "Display" sub-section and setting a different "Virtual" value in there, rebooted, nothing changed.
• Tried various xrandr command variations with the --fb and/or --panning parameters set to the desired maximum (8960x2160+0+0), again to no avail. (output: xrandr: screen cannot be larger than 8192x8192 (desired size 8960x2160))

I did read a claim somewhere (EDIT: here) that Intel's graphics processors do not support greater virtual screen resolutions than 8192x8192 pixels (my system is using a Core i7-6700HQ CPU with the Intel HD Graphics 530 graphics processor), but I unfortunately have been unable to confirm this information - hopefully this is not the case.

EDIT: It is indeed probably not the case:

#: glxinfo -l | grep GL_MAX_TEXTURE_SIZE
GL_MAX_TEXTURE_SIZE = 16384
GL_MAX_TEXTURE_SIZE = 16384

My xrandr output (I currently have the third monitor positioned bottom-right, hence the 8192x3600 virtual screen resolution):

As you can see in the image-- interface loopback and interface any are running all the time. In my understanding loopback is to communicate internally with applications.

But not sure what interface "any" is for with "Encapsulation type: Linux cooked-mode capture". Could it be the Java plug-in? I do have Fruho vpn manger installed but not running.

$ ifconfig only shows two interfaces Loopback and wired or wireless.

Before, I was using Gnome desktop on Ubuntu 14.04. Then, I installed Xubuntu desktop and, just recently, when I login it does not work. I don't know what's wrong.

When I drag something, its' image repeats many times (see below) and stays on the desktop and nothing works. Gnome is still ok.

How can I restore Xubuntu desktop to its' defaults?

Hi. I've got a working Ubuntu 12.04 server, which is going to serve as media server. I've added two disks of size 3TB to put my data on, and I wish to combine these as one 6TB logical volume which I could mount under /media.

So far, I have created one partition on each disks with fdisk and formatted them to ext3. But now I am stuck on how to continue. Do I use Mdadm to create a Jbod array? Or do I use LVM to make a logical volume of these two disks? I can't seem to find the documentation I need, it's mostly about extending existing volumes or installing a fresh system which I don't need.

My OS is on /dev/sdc1 (it's a USB thumb-drive), and the two newly created partitions are on /dev/sda1 and /dev/sdb1.

Hope you can give me some directions.
