Intel NUC 15 (LAPBC510) Internal Speaker And Mic Not Working After Reboot https://askubuntu.com/questions/1566177/intel-nuc-15-lapbc510-internal-speaker-and-mic-not-working-after-reboot

I have an Intel NUC 15 (LAPBC510) laptop. Yesterday, before installing Ubuntu 26.04 on my system, I tried a live boot-up via USB. Everything worked fine when the operating system first started, but after logging out and logging back in, the built-in speakers and microphone stopped working. When I checked the settings menu, the speaker name appeared in the sound menu, but the microphone wasn't visible in the system! After installing on the SSD, the built-in speakers and microphone worked when the system first started, but the same problem occurred when I shut down and restarted the system.

I tried the steps in the link below to fix this, but the result was the same.

Multiple monitors with nVidia on Ubuntu 26.04 https://askubuntu.com/questions/1566175/multiple-monitors-with-nvidia-on-ubuntu-26-04

Anyone knows if problem with support for multiple monitors on Ubuntu 26.04 is going to be resolved since there is no backwards compatibility to X11 anymore.
I've checked release notes etc. and this supposed to be working but it's not :(

Kubuntu 24.04 X11 desktop hard freezing ~hourly https://askubuntu.com/questions/1566169/kubuntu-24-04-x11-desktop-hard-freezing-hourly

(crossposted from Unix & Linux Stack Exchange)

As the title says, I am encountering an issue with the desktop becoming entirely unresponsive somewhat randomly, and I am unable to bring up terminal. My only option so far when this happens has been alt+prtsc+REISUB to reboot cleanly, as it is unresponsive to everything else except holding the power button.

(My computer froze as I was writing the above paragraph, it really is rather inconvenient -- one reboot later)

Originally, I thought it was due to some problem with Firefox since it used to also happen while Firefox was doing something intense like a complex Desmos animation or Google Earth. I have uninstalled Firefox and instead installed Librewolf, and I can do these same things without it freezing. However, the freezing still occurs, now just randomly.

Noteably, neither the CPU nor RAM usage spike when it freezes, in fact for almost all of the freezes both my RAM and CPU usage has stayed below 10%.

journalctl -b -1 -ke is silent between boot and freeze, but says this two minutes after the freeze:

Please do let me know if there's any more information you need. This has been plaguing me for a little under a month now, and it's starting to get in the way of presentations I have to give.

Addendum - The latest few freezes show nothing unusual in /var/log/syslog and absolutely nothing in journalctl up until my sysrq, the computer just... stopped. The screen just completely froze with nothing to go off of. Are there any other logs that I can check that could possibly hint to what is actually going on?

Addendum 2 - details and notes

  • The freeze happened a couple times when I attempted to open Librewolf during the first 5 seconds after booting. It also happened once when I attempted to find a string in syslog (~300,000 lines) in Kate.
  • It does seem like sometimes the freeze exhibits the kwin_scene_opengl message in /var/log/syslog and sometimes it does not. When it does, the message is actually logged a few seconds after the freeze (most recent one was 15 seconds after the desktop froze). It's entirely possible this is two separate issues causing a similar freeze. It's also possible that the times the message is not in the log I simply restarted the computer too quickly.
  • I have tried following the process for disabling the Ryzen C6 power state here with no change, and I have tried disabling the amdgpu kernel module, resulting in no display out at all.
  • A couple times, only the desktop froze, and I could still move my mouse around, until I tried to cross a screen border with the cursor at which point it froze as well. The most recent one had the kwin_scene_opengl message, 13 seconds after the desktop froze.
Ubuntu Studio 26.04 Manually set display coordinates for multi-displays? https://askubuntu.com/questions/1566168/ubuntu-studio-26-04-manually-set-display-coordinates-for-multi-displays

Just setting up Ubuntu Studio 26.04 and having issue with multiple displays.

I have four displays, three side by side and one centered above those. The one above is 3840x2160. The three side by side are 1680x1050, 1920x1050, 1680x1050 respectively.

In the KDE settings app the displays snap to each other when dragging them into the positions I want them. Unfortunately, they all want to align so that they share the same bottom Y coordinate. They don't seem to be able to use the top coordinates for snapping. That means that, instead of being able to align the 4k display's bottom to sit snugly at the top of the three smaller displays, the center one of the three lower displays overlaps into the 4k's display area. This is due to the different resolutions of the center vs the side displays. If I try to address it by moving the center screen lower, the side screens develope a gap causing mouse issues when trying to cross over between displays.

I've not found a way to set the coordinates manually, something I used to be able to do with xorg.

I can think of a couple of workarounds but don't know if they're possible and haven't found anything on them yet. The first would be to turn off the snapping and be able to drag the displays where they need to be. Zooming would be helpful if this is used. I dooubt it's possible but, if it is, could someone point me to how to do it?

The second would be to find some file someplace that I could manually enter the XY coordinates in, either that or find a way to do so in the KDE settings. Again, if someone could point me to a way to do this, it's much appreciated.

Lastly, I'm using the nouveau driver for this. When I tried an install with the nvidia driver there were other, worse issues than these, like no 4k display at all. Card is RTX3060.

thanks, babag

Sudden Jump in initrd.img SIze Filled /boot Partition https://askubuntu.com/questions/1566167/sudden-jump-in-initrd-img-size-filled-boot-partition

I went to update my system today and encountered a strange problem that has left my system in a perilous state. I've done this hundreds of times so didn't expect anything to go wrong.

I ran sudo apt update; sudo apt -y dist-upgrade; sudo apt -y autoremove as usual and got an error from initramfs complaining that my /boot partition is full.

/etc/kernel/postinst.d/initramfs-tools:

zstd: error 25 : Write error : No space left on device (cannot write compressed block) 
E: mkinitramfs failure zstd -q -1 -T0 25

I checked it and was confused, because it was only 60% full.

It's obvious what's causing the problem, which is a sudden doubling of the size of the initrd.img files, but why are they suddenly so much bigger? I managed to fit both images onto the /boot by changing /etc/initramfs-tools/initramfs.conf from MODULES=most to MODULES=dep (in initrd.img contains unnecessary modules after distro upgrade to 22.04), but that leaves my boot partition almost full:

This leaves me with no headroom in case of future expansions of initrd.img size and also I'm concerned that I excluded a module that will be important. Why did the initrd.img size suddenly jump? Is there any solution here short of a risky resize of my /boot partition?

Traditional titlebar icons in Klassy are too thin https://askubuntu.com/questions/1566164/traditional-titlebar-icons-in-klassy-are-too-thin

Uppon trying out Klassy and the traditional window titlebar icons in KDE Kubuntu 25.10, I noticed that there where only two modes: Fine and Bold. I was wondering if there is any way to put an inbetween thickness value maybe by setting svg stroke. I also tried the Metro option or the Fluent but made no difference, its really hard to see and the bold opinion only makes it really intense without havibg any luck with the "Bold on HiDpi" option.

Can anyone help me?

Xubuntu 26.04 not showing Private Use Area (PUA) characters https://askubuntu.com/questions/1566162/xubuntu-26-04-not-showing-private-use-area-pua-characters

I recently upgraded to Xubuntu 26.04, and I've noticed some characters are showing as squares. I looked the codes up and it seems like it specifically doesn't show "Private Use Area" codes.

This site shows like this on my PC

I've installed fonts-noto and all of the variants of that Xubuntu seems to have available, but it didn't fix this.

24.04 noble-updates multiverse Packages.gz and .xz file size and hash mismatch https://askubuntu.com/questions/1566161/24-04-noble-updates-multiverse-packages-gz-and-xz-file-size-and-hash-mismatch

I run a local 24.04 mirror and hit this issue today.

Should I be concerned that the latest noble-updates multiverse Packages listing fails sha256 hash and file size? Very easy to confirm here:

http://archive.ubuntu.com/ubuntu/dists/noble-updates/InRelease

In that file, note:

 7bf55eb5acadfd2fcd0b7696ea1eda6bcde15f7f839b6e75452cd930fc5bd151            38019 multiverse/binary-amd64/Packages.gz

Then compare with:

http://archive.ubuntu.com/ubuntu/dists/noble-updates/multiverse/binary-amd64/

Which lists Packages.gz being 53k in size. InRelease shows it should have a size of 38k. Similar for Packages.xz. sha256 of course fails as well, which is what tipped me.

How best to dual boot two versions of Ubuntu https://askubuntu.com/questions/1566158/how-best-to-dual-boot-two-versions-of-ubuntu

I wish to create a dual boot on my system (a Lenovo Think Pad P16 gen 2 with an NVidia 3500 RTX GPU).

My current system is Ubuntu 24.04.3 with Kubuntu loaded on top of Ubuntu as a desktop flavor. I have no problems with this system, and want to keep running it for now.

I would like to do a fresh install of Kubuntu 26.04 and just restore my old files into it, however I am almost certain that this would not work. When I purchased this laptop from Lenovo in January, 2025, it came preinstalled with Ubuntu 22.04, a distro that was almost three years old at that time. No upgrade option to 24.04 was offered. I tried all sorts of things, none gave me a system that fully incorporated the GPU. Eventually, I learned that certain Lenovo proprietary drivers (jiyai and sutton) required to run 24.04 with my hardware were not yet available. Finally, around June 2025, these drivers became available and I was then able to upgrade my system to 24.04 successfully. That's 14 months after 24.04 was released!

I don't think I'm wrong to think that there might be a similar or longer delay in Lenovo providing the necessary support for going from 24.04 to 26.04. It might be longer since the upgrade would involve using kernel 7.0 instead of 6.x and Wayland instead of x11.

So my thinking is this: Let's get a dual boot going with my initial 24.04 continuing as my main OS and a small partition containing 26.04, accessible via GRUB but needing NO connectivity to the 24.04 system. I could just log into it from time to time and check if Lenovo had released the hardware drivers necessary for the system to run properly. Once I found that it had, then I could reflash the new system and get going with it.

How might I accomplish this?

Find all jpgs in a directory and convert to pdf https://askubuntu.com/questions/1566157/find-all-jpgs-in-a-directory-and-convert-to-pdf

The name of the directory within dir will change so I tried using find. First time using bash so I couldn't seem to wrap my head around piping just yet. The best I came up with was:

var="$(find dir -mindepth 1 -type f)"
magick var output.pdf

but keep getting the error:

magick: no decode delegate for this image format `' @ error/constitute.c/ReadImage/746.

If theres a way to pipe it I'd much appreciate the answer, but I struggled immensely with that as well and I've finally given in.

AMD boot conflict https://askubuntu.com/questions/1566156/amd-boot-conflict

This is a continuation of a previous issue that started last year. I have been avoiding the issue by simply leaving the computer on once I somehow managed to get to a place everything worked but a printer issue forced me to close down.

Every time I try to log in the boot fails and freezes on the Ubuntu screen. I can get to the 'rescue' screen via the Escape button but the low graphics make everything impossible. I am being told that amdgpu should work fine with my graphics card but when I check the error boot log I get this which I assume is the cause of the problem:

Apr 27 22:16:16 roland-desktop kernel: amdgpu 0000:03:00.0: amdgpu: Fatal error during GPU init

I have tried loading the AMD recommended driver and that didn't work. Neither does 'nomdeset' or reloading Ubuntu fresh (I have already lost many files). I have tried all the other suggestions I can find on the net including reloading amdgpu. The card and amdgpu are detected and listed when I search.

Anyone got any clue as to what I should try next, this is driving me insane. I KNOW the card/driver can work it's just every time I turn the computer off it seems to 'revert' and then I can't get it to boot with full graphics.

How to move thunderbird's local storage to a different partition? https://askubuntu.com/questions/1566155/how-to-move-thunderbirds-local-storage-to-a-different-partition

I am using Thunderbird on a computer with limited storage in the root directory (and hence, in home). But I have a lot of storage in another partition.

Thunderbird is set to download a copy of all my emails. How to move its storage to a different partition?

I am using Thunderbird on Ubuntu 24.04 with the APT package, without snap.

Thunderbird is not in the application menu? https://askubuntu.com/questions/1566115/thunderbird-is-not-in-the-application-menu

For 26.04 I did an almost complete reinstallation of my system, only keeping my home drive but formatting all system drives.

I installed Thunderbird with apt, and it works fine with all my old settings and configurations.

But it doesn't show up in the applications menu... If I press the Windows key on my keyboard, searching for e.g. Vivaldi (my browser of choice) allows me to find and start it just fine, but Thunderbird does not show up. I have to start if from a terminal.

The /usr/share/applications/thunderbird.desktop file is there and seems to be fine.

I've logged out/in and restarted my computer multiple times to no avail.

Was something changed in regards to mail and/or Thunderbird in 26.04? Why can't I search for it?


Addendum: The application doesn't have the Thunderbird icon once I run it. Could possibly be related.

How to get wifi work in Ubuntu 26.04 persistent live session? https://askubuntu.com/questions/1566036/how-to-get-wifi-work-in-ubuntu-26-04-persistent-live-session

Wifi does not work in the live session, but I have wired networking available. However, if I want to enable wifi connection, is it a good idea to install a proprietary driver for the hardware. And is it a problem, if I boot the USB Ubuntu in another computer that uses a different driver when it has the additional driver?

How can I install the driver?

I tried running sudo apt update with the following output: enter image description here

And I tried to install software-properties-gtk. That one is needed in Ubuntu to install additional drivers, right? enter image description here

It is 8GB flash drive and the laptop has 8GB RAM. enter image description here

Ubuntu 24.04 headless USB autoinstall failing (Ventoy + UEFI) https://askubuntu.com/questions/1564458/ubuntu-24-04-headless-usb-autoinstall-failing-ventoy-uefi

Headless Ubuntu Server 24.04 autoinstall via USB (UEFI + Ventoy)

I’m trying to create a USB drive that can install Ubuntu Server 24.04 on multiple bare-metal nodes in a fully headless way.

Expected outcome

  • Boot priority set to USB HDD

  • System installs automatically with no monitor, keyboard, or mouse

  • No manual input required at any stage

  • OS installs on the only internal drive present (each node has exactly one disk)

  • Swap should be disabled

  • Works across nodes with:

    • Different CPUs

    • Different RAM sizes

    • Different storage devices (NVMe / SATA SSD)


Current Setup

  • USB created using Ventoy

  • ISO Image -> ubuntu-24.04.4-live-server-amd64.iso

  • ventoy.json configured to load user-data for autoinstall
    → This part is working

  • BIOS set to UEFI only

  • Verified:

    /sys/firmware/efi
    

    exists, so the system is booting in UEFI mode.


What’s Working

  • Ubuntu ISO boots

  • Autoinstall is triggered

  • Cloud-init reads user-data


Issue

I’m getting the following error during installation:

Error Snapshot


Questions

  1. What is the correct generic storage config for:

    • Single disk (any size)

    • GPT

    • EFI partition

    • Root partition

    • No swap

  2. Is there a recommended minimal storage: config for heterogeneous hardware?

  3. Is there anything specific required for UEFI-only autoinstall setups?


Additional Context

  • No PXE — USB-only deployment

  • Goal is repeatable install across homelab nodes

  • Ubuntu Server 24.04 LTS

  • Headless-only environment

Auto update will not boot. Kernel Panic! Please reboot your computer. VFS: Unable to mount root fs on unknown-block(0,0) https://askubuntu.com/questions/1554324/auto-update-will-not-boot-kernel-panic-please-reboot-your-computer-vfs-unabl

enter image description here Kernel Panic! Please reboot your computer. VFS: Unable to mount root fs on unknown-block(0,0)

The above screen is all I get when trying to boot after another auto update. I got that screen after the kernel 6.14.0-24, and dropped back to using 6.11. And then today, another auto update which installed 6.14.0-27. And that screen shows up with that as well. I've never worked with this error before, so don't really know how to proceed. Naturally I would rather not reformat the HDD by reinstalling Ubuntu 24.04.

enter image description here

To get back to normal, I've had to drop to the kernel 6.11.0-29, then I thought that I'll use Boot Repair. Dunno what magic it does but I could then boot to 6.14.0-24. I tried the Boot Repair magic again in that kernel, but I still can't boot to 6.14.0-27 without getting that screen above.

What is that screen telling me? Note I'm not a power user. Ubuntu works so well, I seldom need to open the hood or dig too deep.

Further info: I don't want to use 6.14.0-24 because the res is only 1024 and doesn't change in Control Center and can't be changed higher as higher res isn't shown as available. Even with the res set for 1920 in GRUB it comes up in 1024.

More info: I tried the suggestion from david and that didn't work. Didn't change the results when I boot. Still get the red-screen-of-death. It did however fix the boot to 6.14.0-24 however, I cannot get it to boot to anything other than 1024 screen size as I posted above. Anyone know how to force it to give me a higher screen res?

Final post: I gave up trying to solve this problem. I was able to burn the live Ubuntu 25.04 ISO to an SD card, did a full clone of the drive, and then installed 25.04 to one of them. The funny thing was when I connected the drives and tried to boot to either of them, what showed was the "No boot drive found" error message just after the BIOS splash screen. If I unplugged either drive from the PC's SATA cable, then I could boot to the connected drive. It's strange that the kernel panic could prevent booting now that there's a bootable 25.04 drive. So I couldn't copy the Home folder with both drives operating, instead booted to the 25.04 drive, hooked up my external cloning/docking tool, installed the 24.04 drive in that, plugged the USB cable into the PC, and copied the files that way. Anyway, I'm up and running with 25.04 now. That only took 4 months to get there.

The reason I wanted to upgrade from 24.04 to 24.10 and then to 25.04 was tradition and the fact that it takes freakin' hours (I'm to hour 6 now) to get all my favorite apps reinstalled and configured. Even then there are problems. Every route I took trying to upgrade in the steps needed ended up in frustration and failure, so installing a full new fresh installation of Ubuntu 25.04 was the only option I had left.

Booting from live disk stuck on "EFI stub: Loaded initrd from LLINUX_EFI_INITRD_MEDIA_GUID device path" https://askubuntu.com/questions/1513209/booting-from-live-disk-stuck-on-efi-stub-loaded-initrd-from-llinux-efi-initrd

I want to experiment with Ubuntu on a Lenovo laptop which has Manjaro installed (and nothing else, no Windows). I downloaded Ubuntu-24.04-desktop-amd64.iso on a Windows machine and burned it to a USB stick. After a lot of trouble I got the boot process to start on the Lenovo and fixed the black screen by typing e at the Try Ubuntu without installing option and replacing quiet splash with nomodeset, then F10 to boot. But now I am stuck with this message on the screen: EFI stub: Loaded initrd from LLINUX_EFI_INITRD_MEDIA_GUID device path What next please? EDIT 24 May 2024 - I never did solve the problem. I changed to a different machine and have stopped trying to use the Manjaro machine for Linux. I have wiped it, installed Windows, and will keep it for things that won't run on Linux.

Disable touch screen https://askubuntu.com/questions/1392690/disable-touch-screen

I just installed Ubuntu on an old Dell laptop where Windows 10 was out of service life. This computer is a touch screen. The screen has been cracked for years. Whenever I did a major window upgrade I had to go into device drivers and disable the touch screen and all was fine. How can I do this with Ubuntu? I'm having the old screen issues with Ubuntu. I'm a newbie. Thanks, Dave

How to display KDE lock screen time in 24-hour format https://askubuntu.com/questions/783184/how-to-display-kde-lock-screen-time-in-24-hour-format

Running Kubuntu with the Plasma desktop, 16.04.

I have my desktop configured to 24-hour time, which is what I vastly prefer.

But when the lock screen comes on, it shows me the detested AM/PM format. This cannot stand. Yet after diligent searching, I am unable to find a solution.

Is this configurable in KDE?

Fresh install of Ubuntu 14.04.1 LTS freezes after login https://askubuntu.com/questions/565067/fresh-install-of-ubuntu-14-04-1-lts-freezes-after-login

I am having trouble getting Ubuntu 14.04.1 LTS to work on my laptop, which is a Medion MD 96320 / WAM 2070. I think the specifications are: Turion 64 X2 @ 1.8 GHz processor, 2 GB RAM, GeForce Go 6150 graphics card, and a 160 GB hard drive.

I have tried installing this operating system three times now. I've tried both with having the installer install the updates, as well as without updates. No matter what I do, it installs fine, but then freezes up as soon as I log in.

I have done so much googling about this issue, but can't find anything that's helped me resolve it. I found a few posts talking about Nvidia driver issues, and about running sudo apt-get install nvidia-current and so on. I tried that before and it somehow just got even more broken and mangled, and wouldn't even boot up anymore, so I had to reinstall Ubuntu yet again. Now I can't even try that anymore. I did a fresh boot, and as usual it freezes up when I log in. But now I can't even access the terminal to try anything - pressing Ctrl+Fn+F2 at the login screen just takes me to a black screen with a "_" character drawn in the top-left corner, but I can't type anything.

What am I supposed to do? How do I get this to work?

I don't have a lot of experience with Linux, but it's always intrigued me and I was excited to play with Ubuntu, so this is really disappointing. This is the third time I have attempted to use Linux in my life (with different distros and computers), and it never, ever, ever works. It's so incredibly frustrating to just keep trying the same thing over and over and have it never work. I was really hoping that I could give this old laptop a "new lease of life" as they say, due to Linux running better on weaker hardware than Windows. I'd really appreciate it if someone could help me figure out how to fix this.

Thanks, and Merry Christmas.

How can I disable USB autosuspend for a specific device? https://askubuntu.com/questions/185274/how-can-i-disable-usb-autosuspend-for-a-specific-device

This is related to the issue discussed in Wireless mouse temporarily freezes (sleeps) on battery power.

Summary: the mouse freezes when operating on battery since it is autosuspended after a certain time and needs more time to wake up.

Disabling USB autosuspend for the mouse's receiver in PowerTOP is a temporary solution, but it does not survive a reboot.

How can I permanently disable the USB autosuspend for only one specific device?

A solution that does not involve installing additional packages is preferred (after all, I want to disable something), but it is not required. Removing PowerTOP (which seems to be a solution for some) is not what I want - I like PowerTOP...

And installing laptop-mode-tools to disable USB autosuspend altogether is not what I want, either, thus the new question.

Also: Will this affect the battery of my notebook? The Logitech unifying receiver for the mouse stays connected all the time, so if that prevents the autosuspend from happening for all devices that would probably be bad.
