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":

Audio source that's showing audio, but doesn't come out of my headphones:

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:

Trying to bring hci1 back up using sudo hciconfig -a hci1 up only results in a timeout error.

Using sudo dmesg |grep -i bluetooth brings this up as well:

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?

I forgot my password for Ubuntu on my Samsung laptop. From (Recovery menu, Drop to root shell prompt, Give root password for maintenance) I've tried unsuccessfully: mount -o rw,remount /.

I am running Ubuntu 26.04 and want to share my clipboard with a VirtualBox 7.2.6 host.
I have installed all apt updates and snap refreshes.
I also installed the VirtualBox 7.2.6 client additions.
I tried cutting and pasting text from host to client and client to host and it does not work.

Is anyone running Ubuntu 26.04 and is able to copy-and-paste text from host to VirtualBox client?
How do you do that?

I'm using the following command to update HTML files

sed -e "s/SRC=\([A-Za-z0-9.\/_-]*\)/SRC=\"\1\" /gi"

I'm having trouble adding + and & to the above as valid filename/path characters. My best understanding is that these special characters need to be escaped, like so:

sed -e "s/SRC=\([A-Za-z0-9.\/_-\+\&]*\)/SRC=\"\1\" /gi"

but I suspect the added bash command line complexity has me stimied. TIA.

After installing Kubuntu 26.04 on my Slim 3 with Ryzen 7 7735HS, i noticed that sometimes my machine wont wake up from suspension, it acts like it is suspended, with external devices RGB off and with the power button blinking as it should. but when trying to resume by pressing any key or pressing the power button once, it wont wake up. I need to hold the power button until it turns off and then press it once to turn on again, and when this happens the battery protection mode always turns off and i need to turn it back on. I made a post about that here before, and a suggestion was made by someone for me to update my BIOS. I did it through a HirensBoot formated with ventoy, since it was my only option (i dont have windows and the only installation media available is an .exe file on the lenovo site). Was pretty confident that this was going to solve my problem, but it persisted and now, a few days after the update, my computer wont turn off most of the time. In that state, everything looks exactly like when my computer is powered off: Black screen, no rgb in external devices, but the power button glows white as it does when the computer is on. And my battery drains somewhat fast (drained about 80 percent after one night and one morning). Can someone please help me with those problems??

My professional laptop Dell Precision is under Noble 24.04 installed after delivery (delivered under Jammy).

I am french so I used fr (bepo) keyboard layout.

I stay with X11 to use Gimp, have no issue with web-conferencing app …

Early may

I still had kernel update (6.17.0-22) that switched me under wayland and qwerty keyboard layout, I run in CLI: setxkbmap fr bepo that returns me: WARNING: Running setxkbmap against an Xwayland server, I swithed back to kernel 6.17.0-20 and X11.

This morning (17th jully)

After a first use, my laptop locked up after being idle for a while, then when I entered my password, I can't connect… it switched to qwerty. I also connect to the docking station to have external screen, but it stayed black, no external screen detected in display parameters. I had no more wifi connection, I should connect by cable.

I didn't find under grub connection to switch back to X11, so I switched in /etc/gdm3/custom.conf the WaylandEnable=false, but if I switch with success to X11, I still had no wifi, external screen.

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.

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?

Chromebook in question: HP Chromebook x2 - touchscreen tablet with detachable keyboard.

Following the guides on mrchromebox.tech, I was able to get Lubuntu installed. Everything is working great except the trackpad. The cursor "warps" to the corresponding location on the screen to wherever I touch the touchpad (if I touch the top left of the touchpad the cursor instantly moves to the top left of the screen) and it constantly clicks and drags as I move my finger around the touchpad.

Touchpad in question:

I haven't used Linux in a decade or so so you'll have to excuse my ignorance. I used AI to give some bash commands for the below info. Let me know if I can provide more info.

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?

I am getting this error message now when I try to use Steam,

Steam now requires user namespaces to be enabled.

This requirement is the same as for Flatpak, which has more detailed information available: https://github.com/flatpak/flatpak/wiki/User-namespace-requirements

The documentation on GitHub may as well be in Martian.

I am running Ubuntu 24.04.4 LTS, all up to date, on a Lenovo V15 G4 ABP. Steam is installed via the App Center.

This is set: kernel.apparmor_restrict_unprivileged_userns = 1

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'm on Ubuntu 24.04, I have installed rhvoice and speech-dispatcher, and this works fine from the command line.

My use case is that, as a writer, I want to be able to get the machine to read my text aloud to help check it. I used to use an online service but it's really expensive. I don't need Orca because I am not visually impaired and it would be overkill.

I write with Scrivener on WINE, so that's not going to integrate easily. I have tried getting LibreOffice to talk using the Read-Text extension but that's not working either (I have queried that on the LO forums because it's doing something truly weird).

My ideal would be being able to slap the text (a chapter at a time) into a text editor (for example) and have it read back (pausing would be great but a paragraph at a time would be acceptable).

So does anyone have any idea what I could use? Am I going the wrong way using speech-dispatcher even though standard APIs are good, right?

The speech output doesn't need to sound natural, in some ways it's better if it isn't for my purposes.

After putting core.editor=vim to git's config is there a way to force git to launch vim with .vimrc other than $HOME/.vimrc? I mean I would like to have different settings for my day-to-day vim (which is $HOME/.vimrc) and other one for git tasks.

One can create aliases for all git commands (like git commit, git difftool) invoking vim. These aliases would, for example, launch external bash script that prepares everything, but it's not the way I would like to go for. Something I have in mind is:

• Putting path to custom vimrc into ~/.gitconfig
• Setting some variable similar to SSH OPTIONS

Is there something like that?

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.

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

How can I make Thunderbird to pin selected emails to stay always on top?
I can't find this feature in Thunderbird, there is a pin icon but it looks like it only "keeps the filtering when changing folders", whose function is not too clear to me. Also, suggestions on this (and possibly other) add-ons are 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:

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:

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?

Is there any macro recorders for ubuntu? I want a program that i could assign a key to do a recorded mouse movement and keyboard typing. Thanks

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...

Trying to run a game & the game opens the closes right away & in the terminal it says "libEGL warning: DRI2: failed to authenticate"

I have searched for weeks trying to fix the problem. All I found is

1. Ubuntu has a bug that has not been fixed yet?
2. Nvidia drivers do not have DRI2 Support?

Anyone know how to fix this, Its driving me nuts. I have tried Nouveau drivers and I get even more libEGL warning errors

I am running Ubuntu 14.04
