I have a small server (Zotac Zbox) running Ubuntu 24.04. Twice now it's had an entire series of corrupted files on the HDD. (This time it's affected apt such that apt --fix-broken install fails; I think a reinstall will be required regardless.) It'll hang at boot complaining that a manual fsck is needed, then give errors like "inode <inode id> seems to contain garbage". The SMART diagnostics aren't finding anything wrong.

1. How can I tell if there's a hard drive problem doing this? What other troubleshooting can I do to try to narrow it down?

2. What can I do to prevent it in the future?

SMART data is below. I'm currently running an extended test; the short test at 15677 hours was this evening, and I believe the two tests at the 86xx mark were last time this happened. (No telling how long it had inode errors between these two. It is very rarely rebooted.)

I'm running a Dell Optiplex with integrated intel video card. I recently upgraded from a live USB, wiping the root directory, but kept my home directory in place.

Since upgrading to 26.04, I can hear my fan rev up any time my browser tries to load a page with a lot of images. Like Amazon or Ebay, where there's an array of images on a page. I don't know if it's this or the Javascript, but it takes a long time to load and I can hear the fan always revving up.

Mouse performance becomes choppy over time. I'm running dual monitors, the first with Displayport and second with HDMI and when I move the cursor from the first to the second, I can see it stutter.

In general, I'm just getting laggy performance and it feels like a video card-related issue. Has anyone been having these problems, and how do you fix them?

I'm trying to install the Ubuntu Server operating system, but unfortunately at the last stage of installing, the installation logs, the 'Reboot now' button is not showing up. I've waited for fifteen minutes. It is an older laptop (Dell Inspiron 15 5000 series i7. I'm pretty inexperienced with this kind of thing. Is it just slow or is there something wrong? Also, my Ethernet connection is not working properly. I don't know if this has something to do with it.

I also can't backtrack by pressing the Esc key or a 'back' option. The version I am using is "ubuntu-26.04-live-server-amd64".

Finnally downgrade 'input|output' less timings into insider circular-direction design forms may reduce it's move spread all around display-screen.

I use an Asus E510 laptop. After upgrading from Ubuntu 22.04 to Ubuntu 24.04 the left audio channel is now shared across both speakers on the output device (my TV) and the right channel audio signal is not sent.

Clean booting into Ubuntu 24.04 or Ubuntu 24.06 from a live disk also causes the problem, so it is not a problem caused by a damaged or jumbled upgrade. Clean booting back into Ubuntu 22.04 from a live disk fixes the problem again, so it is not a setting on my TV nor is there anything wrong with my laptop or HDMI cable. I have also tested with multiple HDMI cables to be sure.

There are also issues with the new 5.1 and 7.1 HDMI output modes in Ubuntu 24.04 and onward where the right side channels do not respond appropriately.

This is an untenable situation.

I am getting the apparently common problem of a boot partition with 0 space left. I have gone through the best links that I found so far, but with no luck resolving it (partly because I'm a noob).

How do I free up more space in /boot?

The autoremove command does not work because it needs to create files, but there is no space left to do so.

The sudo apt-get purge command also fails due to an attempt to create files again was met with no space left.

The boot partition is 2GB and attempting to expand partition doesn't work (using Disk Utility) because there is no non-filesystem free space left on the 2TB drive.

I'm at my wits' end. Current kernels listed:

When I start up Xubuntu, my audio profile is automatically switched to digital output because it believes analog stereo is "unavailable" and the front headphones are unplugged (they aren't) and even when I manually set these settings, I get no sound, despite PulseAudio control panel showing activity in the volume indicator. There are no other audio output sources active.

Window showing analog as "unavailable":

Window showing headphones are "unplugged":

What do I do?

After a routine fwupd firmware update my laptop's built-in screen became very dim, even at "100%" brightness. An external monitor on the same machine looks completely normal.

• Laptop: Dell Latitude 5430, Intel Iris Xe (Alder Lake, i915), internal eDP panel (AU Optronics).

• OS: Ubuntu 24.04, GNOME.

• Trigger: fwupd auto-flashed the Dell system BIOS from 1.36.0 to 1.39.1 (check with fwupdmgr get-history). The screen was fine before that.

What I already ruled out (none of these help):

• Not a kernel regression — dim on every kernel I tried; the panel is only bright in recovery mode / with nomodeset (i.e. when i915 is not driving it).

• Not gamma/ICC — xrandr Brightness 1.0, Gamma 1.0, no VCGT in the ICC profile.

• Not a software brightness slider — /sys/class/backlight/intel_backlight reports brightness == actual_brightness == max_brightness (1023), yet the panel is dim.

• Brightness keys only make it dimmer, never brighter.

• Downgrading the BIOS is blocked: LVFS only offers 1.39.1, so fwupdmgr / GNOME Firmware cannot roll back.

How do I get the panel bright again without a BIOS downgrade?

For starters, here is my system. EDIT: My headphones are Skullcandy ANC Crusher 2, if that also helps.

It started when trying to fix a connection issue between KDE Connect and my Android. I changed my firewall settings to "allow" and while it fixed the KDE Connect issue, it caused my bluetooth audio to sound choppy and distorted in A2DP sink.

I then tried a few fixes for that from here and here and here.

And now bluetooth has disappeared from my system tray entirely, with no way to reconnect it.

Running hciconfig shows this:

Not sure what I'm missing here. I tried some instructions to also reinstall the entire bluetooth stack with no luck either. Any ideas would be greatly appreciated.

UPDATE: Apparently I can still connect my headphones using bluetoothctl using the scan command to get the MAC address of the headphones and then forcing it to pair. Audio is still choppy but now I'm wondering what is really going on. Perhaps it's just an issue with the system tray itself? Bluetooth apparently does work, but it's a pain to do it this way every time.

I was stupid enough to fall for what purported to be an e-invitation in my inbox from someone in my address book. I went so far as to click on what was labeled as “View Invitation” and landed on some page that said something like “that event has already past” before it dawned on me that I might have just been pwned.

First sensible thing I did was put the device (laptop running Ubuntu 24.04.4 LTS) into airplane mode (I'm typing this on another device). Then I checked the full message body. I didn't see anything that looked fishy in the SMTP headers, but careful inspection of the visible message reveals it's bogus: It bears a surface resemblance to something from Evite, but the URLs that Thunderbird shows when I cursor-hover over various of the message’s features involve paperlessinvguestview.com and paperlessgrandivio.com. (Yes of course I should have glanced at the lower-left corner of the message’s window before clicking: we have already established that I was stupid.)

Next I looked up both domains on check-host.net. For the first one it turned up nothing (so maybe it's already been shut down?), but for the second it resolved to 104.21.72.204, which it attributed to Cloudflare.

Since I didn't type anything at all, let alone any sensitive information, the only bad potential effect I have thought of is inadvertently downloading/running evil things (of course there may be other bad effects that haven’t occurred to me).

My main question is: How can I detect what harm if any has been done?

I figured I could look to see what files had recently been modified, so at the command line I ran:

find / -mmin -240 -mmin +120 -type f -exec ls -lt {} +

Of course this returned some 1300 lines to stdout (plus more than 1400 lines of “Permission denied” to stderr), but when I filtered that by grep -v \.cache, it fell to a manageable 550 lines. Perusing that didn't unearth any smoking guns either, at least not smoking heavily enough for me to recognize it. A whole lot of 0-length files in /proc and /sys/fs/cgroup/user.slice, and some data in some of my password manager’s cache directories; stuff like that. It did occur to me to wonder about all those unreadable (system) directories, but I was reluctant to rerun the find inside a sudo because who knew if, say, I was now running a key logger that would capture my root password.

I have also run ps -aux, but again from out of its 314 lines of output, there is nothing that stands out to me along the lines of rm /*. It was the same for top. Likewise, perusing contents of /var/log turns up nothing that makes ME panic (kern.log, syslog, and auth.log are the only files modified since, and none is obviously shouting, “Danger!”).

I checked out this question and this one too, but I figure a whole lot may have changed in the more or less decade since they were posted.

I guess at some point I will just have to risk connecting again, if only to install something like ClamAV?

Tried to redo the kernel installation, but fails using sudo apt upgrade -y. Had to rewrite initrd configuration before update-grub. Could you kindly check right now. Kindly see below for details

I've recently updated my system through the "Software Updater" app.

After restarting the system the screen resolution was wrong, much smaller than expected and if I look among the Settings I am not able to choose any other screen resolution.

Previously, I was able to solve it by playing around with the settings in the "Software & Updates" app (NB: which is different from "Software Updater").
Apparently, Canonical has decided to remove it from newest versions of Ubuntu (see more: https://www.omgubuntu.co.uk/2026/02/ubuntu-26-04-drops-software-and-updates-gui).

After looking around on the internet I followed some instructions:

• I ran the cmmand ubuntu-drivers devices of which the below is the response from the terminal:

== /sys/devices/pci0000:00/0000:00:01.1/0000:01:00.0 ==

• I followed the instructions to install the recommended driver: sudo apt install nvidia-driver-595-open which returned the following response: nvidia-driver-595-open is already the newest version (595.71.05-0ubuntu0.26.04.1)

• After rebooting the system, the problem persists

What else can I do to solve the problem?

Could the issue be something other than apparmor? A 24.04 system on the same network gives the same DENIED type messages but, the print to PDF happens. On 26.04, I see no output file at all when the print is coming from another system on the LAN

Using 26.04. CUPS print to PDF is working when the originator of the file is on the 26.04 system. The CUPS PDF print is shared with other systems in my local area network. At attempt print to PDF from an XP system in my local area network is failing. The system log contains a few lines such as this

2026-07-16T21:23:36.032922-05:00 localhost kernel: audit: type=1400 audit(1784255016.031:150402): apparmor="DENIED" operation="connect" class="file" profile="/usr/lib/cups/backend/cups-pdf" name="/run/samba/winbindd/pipe" pid=1158626 comm="cups-pdf" requested_mask="wr" denied_mask="wr" fsuid=0 ouid=0

Due to the presence of an XP system in my local area network, winbind is installed.

I've got rid of the above message from syslog by disabling apparmor with regard to cupsd (I think) but messages about dbus-daemon persist, an example is:

2026-07-17T10:06:37.333138-05:00 localhost kernel: audit: type=1107 audit(1784300797.331:152868): pid=1310 uid=995 auid=4294967295 ses=4294967295 subj=unconfined msg='apparmor="DENIED" operation="dbus_signal" bus="system" path="/com/redhat/PrinterSpooler" interface="com.redhat.PrinterSpooler" member="JobQueuedLocal" name=":1.8991" mask="receive" pid=349875 label="unconfined" peer_pid=1168372 peer_label="/usr/sbin/cupsd" peer_info="No such file or directory"

What do I need to change so that this works?

Up until a couple of days ago, everything was honky-dory. Earlier today, I went through a few firmware updates using the firmware-updater GUI and rebooted when asked. I am not sure whether what is happening is tied to that.

I'm on Ubuntu 24.04.

When I launch a terminal, I can see all my files. However, when I open Nautilus, all I see is a snap folder.

Any other link on the left panel, i.e., Downloads, Documents, Music, etc., shows an "Oops, something went wrong" message, while displaying the correct path underneath it. That path is accessible and owned by my user throughout, as I can see from the terminal.

I used to be a Unix/Linux sysadmin back in the day, but later switched to infosec and retired a few years ago. I can still find my way around Bash, but this GUI crap is all nonsense to me. How do I fix this?

Today upon starting my Ubuntu 24.04 Software Updater, I was surprised to see it had Steam updates in it. I excluded the Steam parts and ran the updater. I reran it and it still had Steam updates. I closed it without going any further.

I then started my Steam and told it to check for any updates. It said its already at the last version. So what's going on here? Is this a hacking attempt?

I use Freecad since more than 5 years on Ubuntu.

Freecad, channel stable, doesn't start anymore on all my Ubuntu machines installed with Ubuntu 26.04 (kept up-to-date). Channel edge however, does start.

A loud tikk sound is played when starting with handsfree.

In each use of handsfree this problem occurs only once.

I don't have that problem with the speaker.

I just got the error message "The window terminated unexpectedly (reason: 'clean-exit', code:'0')" while working in vs code. I had launched an app at this point in the integrated terminal, but apart from that did not do anything off.

I now am not able to start vscode anymore as even after uninstalling and reinstalling I keep getting the mentioned error.
OS: Ubuntu Mate

Is there any way of deleting the apparently saved session data without losing all my other configurations? Thanks in advance.

If I start Ubuntu from a cold boot, Internal audio, and Headphones work flawlessly.

But if I start Windows and I reboot to Ubuntu, only internal speakers work, no matter how much I connect and disconnect it from my laptop, the audio comes out of the speakers and not through the headphones even when they are connected.

Here are my logs and dumps:

Can it be a kernel-related bug about this?

I really appreciate any help you can provide.

Node.js is installed but not working. How to solve it?

I am using Ubuntu 20.04 with kde plasma. All of a sudden, my Dolphin file browser takes forever to open. Earlier it opened instantly, but now it is taking almost 30 seconds to start.

This seems to have started after an update; when I use kernel 5.11.0-38-generic there is no issue: the problem occurs when I use kernel 5.11.0-41-generic. In addition when on 5.41 the whole system seems to run slower.

When I run dolphin from the command line, there is no error output, and it is as slow as before to open.

I am using an Intel 4690k CPU with 16GB ram and SSD. I checked my drive health and it is fine.

CopyQ clipboard manager global shortcut to show/hide main window does not work on Ubuntu 21.04 (doesn't work under Wayland windows manager)

I bought a CSR 4.0 bluetooth toogle hopping to use for music and stuff. I have already tried a plug n' play BT toogle but I can't remember its brand or model (it was white though). It worked for 4.0 devices but not for my 5.0 headphone for instance.

When I did the same thing for this "plug n' play" usb toogle it didn't work. After search the web and countless forums I come here again asking for help. Here is a quick list of thinks I tried and some details of the issue:

1. First I installed the bluez and blueman packages (through synaptic) both in dev versions as well. When I open it and try to pair with my phone, it keeps searching endlessly.

2. Also while blueman tries to search, the bluetooth system tool does as well.

3. However, after installing the packages, my desktop is recognizable by my phone. But when I try to pair them: an error mensage apears.

That was pretty much what I did to solve it. The rest was me trying to diagnose the problem. It follows:

Finally I saw that tip in one askubuntu topic and tried my own. The result:

$ sudo hcidump

    lap 0x9e8b33 len 8 num 0
< HCI Command: Reset (0x03|0x0003) plen 0

As a result of the code from another terminal tab

$ sudo hciconfig hci0 down
$ sudo hciconfig hci0 up
Can't init device hci0: Connection timed out (110)

So long I've seen, $ sudo hciconfig hci0 reset also works. Then the bluetooth system manager and gnome control panel behave like this and I have to remove and insert the device to be connected again.

Finally, I read that this could happen as the kernel were updated from Ubuntu 16 to 20. Mine is 5.8.0-43-generic, but people complain about this problem since 5.4. I'm not sure if installing an old kernel would solve it once I know almost nothing about it.

Any help is welcome ;)

Hi I am trying to use Ubuntu-Prime for ubuntu 18 on an asus laptop with 2 GPU (intel & nvidia).

I found the power consumption of the computer to be way too high when I reboot with only the intel GPU (using prime-select intel or using nvidia-settings).

I found that the nouveau driver was loaded despite normally not used:

$ gpu-manager | grep nouveau
Is nouveau loaded? yes
Is nouveau blacklisted? yes
Skipping "/dev/dri/card1", driven by "nouveau"
Skipping "/dev/dri/card1", driven by "nouveau"
Found "/dev/dri/card1", driven by "nouveau"
Skipping "/dev/dri/card1", driven by "nouveau"

I tried to blacklist it and also have a kernel startup option to prevent nouveau from being loaded yet it still loads. This seems very un-linuxy to me.

So here´s what happened:

1 - I have an Imac and was trying to downgrade it from High Sierra to El Capitan by trying to force its installation manually. That corrupted the OS system files and I could not start the Imac.

2 - Then I created a bootable Ubuntu 18.04 LTS into a pendrive and am booting the Imac that way. While Ubuntu does list the drive, it cannot mount it. Therefore, I cannot backup the files to try and reinstall the mac OS again.

So, How do I get to mount the Apple SSD in order to backup my files ?

It´s an 1.0 TB Disk Apple SSD GPT partition, and the imac does not have access to internet, so anything I might need to install in order to fix this i have to get from another computer and use a flashdrive to transfer to the mac.

Hopefully i made myself clear enough, not a code expert so looking forward to the simplest solution to this.

EDIT: Here are some things I've tried:

Every time I download a game from the terminal I can't open it.

Example 1:

$ sudo apt-get install 0ad
Reading package lists... Done

0ad is already the newest version (0.0.22-3.1).

Now when I try to launch O A.D.:

0ad
bash: 0ad: command not found

Example 2:

sudo apt-get install nsnake

same thing...

Now time to run it.

nsnake  
bash: nsnake: command not found.  

I'm a Windows user coming to Ubuntu's Bash thanks to WSL. Now I need to edit some files and I really hate Vi. Do I just have to deal with it, or is there a simpler alternative?

The features I am looking for are:

• CLI based
• easy to use (typing and editing should be similar to Notepad)
• simple editing capabilities are enough

I will try to master Vim, but I need to make a quick edit right now!

I have Mac os 10.12 in vmdk format and used it by VirtualBox on ubuntu.

How to can i convert this vmdk file to bootable Disk or Usb for installing mac os?

My Ubuntu 16.10 uses i915 driver. For some reasons I have troubles with it. So I want to force X to use VESA.

I tried:

1. blacklist i915 in /etc/modprobe.d/blacklist.conf. Then sudo update-initramfs -u. Doesn't work.

2. GRUB_CMDLINE_LINUX_DEFAULT="quiet splash modprobe.blacklist=i915" in /etc/default/grub. Then update-grub2. Doesn't work

3. Added new file 20-foo.conf in /usr/etc/X11/xorg.conf.d with content:

   Section "Device"
       Identifier      "Configured Video Device"
       Driver          "vesa"
   EndSection
   

Doesn't work.

Guys, how on the Earth one could make an OS that requires such an effort just to switch video driver? Maybe I'm doing something wrong?

I got MS word document, person asked me to edit it, to add table of contents, to add page numbers, because she doesn't know how to do in MS Office. So I did with LibreOffice writer. But when I saved (tried several filetypes, including: .doc, .docx, .odt) and send file back to her through facebook firefox and chrome showed error in download list saying

"Blocked: May contain a virus or spyware - "

And actually it says same thing when I download file which I sent and try to open it. And when I did edited this file second time, this time with windows and MS word, everything worked just fine.

So what's the problem here... Do I have virus which is unlikely, not even because I'm on linux, but I know how viruses works and I do not open suspicious files, I'm not going to suspicious websites and this ubuntu 14.04 LTS installed 2 weeks ago.

Something should be wrong with LibreOffice, right.. ?

Can't find any info on the internet about this issue...

And I can replicate this by creating new file with LibreOffice Writer, saved it in .odt with random text with two fonts, Times New Roman and LiberationSeriff, sent it via facebook and can not open it, same error...

Did some experiments and: it's Times New Roman font what caused the problem... What should I do? I need this font...

EDITED: So I turned off this blockage on firefox and I can download file and open it, haven't tried to open it in MS office yet, so not sure if it will work if something really wrong what libre does with MS fonts...

UPDATE: well... everything works in MS Office, nothing bad happened with fonts or document when I opened it. So everything works, but still, browser treats it as virus or spyware. :) I guess LibreOffice guys should know that...
