We have created a volume and mapped it to Ubuntu server from IBM storage. The volume can be accessed and operated as normal (creating/deleting files). However, we face a problem where the IBM storage reported that the physical capacity is nearly full (92% out of 80TB) and that there is no reclaimable space but the volume on Ubuntu only consumes around 40%/~35TB when running df -h.

The storage team suggests that configuration has to be made on the OS side since the original volume is said to be thin-provisioned but the configuration on the OS level has not been configured to act as such. The support team said that configuration is not part of their support service and did not provide a guidance on how to configure volume so that the free space can be reclaimed.

Is there any documentation on how to configure the volume to be able to reclaim this free space?

We installed Ubuntu OS version 24.04 LTS on an HP laptop (HP ZBook Power 16 G11). After the installation, we are encountering an issue where the screen gets stuck at HP Wolf Security and does not proceed to the login screen
Troubleshooting steps performed:

• Executed the sudo apt update command in Terminal to install the latest updates

• Performed dpkg repair and grub update in recovery mode to fix broken installations and update boot entries.

• Verified in BIOS settings Secure Boot was disabled

• Verified in BIOS settings SATA Mode was set AHCI

Despite the above steps, the laptop screen continues to get stuck at the HP logo screen.

My laptop would freeze after a few seconds. I am using Ubuntu 24.04 LTS.
Yesterday when I am using it, nothing weird happen until today my laptop monitor (I use 2 monitor) does not turn on, only the second one. I try update the nvidia in the software&updates. There is a lot of drivers in here so I choose the top one (Nvidia-590) and after restart it will freeze after 10 second and the fan will spin fast.

How do I fix this?

I also dual boot with windows on different ssd (ssd1 windows, ssd2 linux). is it bad to have dual boot like this?

I had the classic problem with my Epson L380 in Pop!_OS: it only printed repeated characters, Ç, squares, √, ■, etc. (gibberish).

I tried several official Epson drivers (.deb ESC/PR), but nothing worked. How to solve this?

I have setup Ubuntu Desktop 24.04 LTS. When I turn on the Remote Desktop (Sharing) options, I am able to access the Desktop all OK. However, I am seeking to have this always remain accessible, and am finding after I reboot the access is blocked until I open the Sharing options again on the PC. I have set the Ubuntu Desktop to auto login, so would have thought that that would work, but is not the case. Hoping to get some assistance to be able to keep Remote access working after a reboot.

I've nearly the last whole 4-5 days attempting to fix some issues which have started happened on my laptop. I'll explain what the original issue was and what the continuing issues are.

ASUS Zenbook 14
Intel Core Ultra 9 (Intel Arc integrated graphics)

My laptop has been experiencing minor issues with ubuntu since I installed it. Mostly minor freezes for ~15 seconds during usage or sometimes it would lock up completely. During the times when it would freeze completely I would restart using ALT + PrtSc + REISUB.

I encountered a new issue though last Friday, when going to boot my laptop. I was met with a black screen with the keyboard lights pulsing. I gave it a few minutes but then decided to force shutdown, and every time after that, no luck, it was stuck.

The boot would always hang on "Loading initial ramdisk ..." I'll spare the rest of the details, but after trying numerous BIOS settings and grub linux options eventually I found that the only option that would get my laptop to boot was setting "intel_idle.max_cstate=1"

I figured that it might be related to my CPU being newer, but since making this change to get ubuntu to boot I've run into numerous other problems. Most notably, performance degraded significantly. My CPU frequency, under any workload, would never exceed 400 MHz. Any input was slow, (about 1/3 of a second delay). Scrolling in any application or browser felt painful.

I tried another option "intel_pstate=disable" which seemed to stop the throttling, but performance was only negligibly better. I have experimented with numerous cpupower settings and manual governing but it seems that the CPU always will fall into a idle state which seems to take over a second to wake from. Disabling idle states with cpupower just locked the frequency at 400 MHz again. Disabling thermald also seemed to stop the throttling cap, but the same issues as above remained. Anything which "repaints" a lot of the screen seems to be very slow and stuttery, and my IDE (webstorm/pycharm) is borderline unusable. My mouse takes about a second to start moving when input is given. CPU heavy tasks are also noticeably slower. All of these things worked great outside of freezing issues before this.

My BIOS is up to date and I have latest graphic drivers, I think. All of my power/governor settings are set to performance as far as I am aware. My thermals are also pretty normal, almost never goes above 70 C.

Is this caused by setting max_cstate to 1 or are there other issues that I should diagnose? Any help is greatly appreciated.

P.S. I'm pretty new to Linux, so please correct me if I'm confidently wrong about something. I also don't know which logs would be most helpful, I'll try to respond as quickly as possible to requests.

A recent auto upgrade from 6.14.0-37 to 6.17.0-14 yields a kernel panic at boot: "Unable to mount root fs Unknown Block (0,0)"

To get the machine up I have to select 6.14.0-37 from the GRUB boot menu. I can no longer do a normal boot/reboot because GRUB auto boots the newest (BAD) kernel. I want to remove 6.17.0-14 from the GRUB menu.

All the help articles I've found instruct how to remove OLD kernel versions. How do I remove the NEWEST kernel version and retain the oldest in GRUB?

HIP (Heterogeneous-compute Interface for Portability) ROCm in Eclipse on Ubuntu: The program runs, but Eclipse doesn't accurately recognize hip. Do you have any ideas?

My notes from 22.04 showed that I ran apt install nautilus-image-converter in order to have the Resize image option available in Nautilus context menu. Now I am running 24.04 and found that Nautilus context menu didn't have the option, so I ran the same command. The only change in the context menu was the addition of a Compress command. How do I get this option on 24.04?

I'm doing a prompt on these two and here's ollama ps for it. I've got 80GBs of memory and the 780M integrated GPU. How do I get Ollama to use that?

I booted from 24.04 USB stick, and can see the hard drive and read all its contents. Do you have any advice on recovering the hard drive?

I'm trying to find an audio graphic equalizer for live audio editing. My laptop has two USB audio adapters one for input (as a microphone) the other for analogue output (as headphones) as well as the standard mic / headphones port.

I've tried using Easy Effects with PipeWire and can do either:

1. audio in for recording and manipulate using the input graphic equalizer.

2. audio out from an app like VLC and manipulate the output graphic equalizer

But so far I can't find a way to connect the input to the output. If you know a way to do this with Easy Effects then I'd love to try it. Alternatively is there another app that will run on Ubuntu?

I am trying to use the sound recorder from GNOME to record mp3 audio files for my lectures, but for whatever reason, it won't start recording and is simply stuck at 0:00. When I try to stop it or trash it, it just will acknowledge I clicked it, but won't actually take the action to do it and becomes essentially soft locked until I kill the task.

The sound recorder works fine when I record in FLAC, but for the purposes of what I am doing, FLAC isn't an option and I'd rather not convert it to MP3 every time. Is there a solution to this?

I am using Ubuntu 24.04 LTS, and I installed it through the apt package manager (sudo apt install gnome-sound-recorder). I am using Ubuntu on a Dell Latitude 5490. And the version is 43.beta.

I purchased a new Framework 13 laptop a few weeks ago and set it up with Kubuntu 24.04 LTS using 6.17 kernel (at .4 point release). All has been working well except for when I tried to take calls with my airpods. I could hear fine through them, but the mic didn't work. After a lot of troubleshooting, I determined that the issue had to do with the fact that I was running PulseAudio and not PipeWire, so I followed this tutorial and was able to fix the problem. Unfortunately, in the process I somehow lost access to my speakers and my headphone port, as now when I disconnect my airpods, the only audio option is Dummy Output.

I have no idea what caused this and was up until 2 am last night trying various fixes with no luck. I'm wondering if maybe the issue is that I'm running an older version of pipewire (1.0.7) as I've seen a newer stable build in some forum posts (1.4.7). I'm open to anything though, this is my first time with Linux as a former Mac user, so I'm still getting used to it.

Audio tab under System Settings, no Bluetooth:

When I run pactl info

Server Name: PulseAudio (on PipeWire 1.0.7)

Let me know what other information would be helpful.

Edit:

I think I might have identified the problem though still unclear on what the fix is. When I type aplay -l into the Konsole, I am met with this:

**** List of PLAYBACK Hardware Devices ****
ALSA lib conf.c:2012:(_snd_config_load_with_include) _toplevel_:2:0:Unexpected end of file

So there seems to be something wrong with my ALSA config. How would I go about fixing or removing it?

In the CLI I have had this happen twice today on two different PCs. In the CLI I can run simple commands like cd or ls -a with no issues. Then I run the update and then upgrade and reboot. When I open the terminal and run the same commands I get permission denied. I am at a loss on this.

I recently installed Ubuntu 24.04.4 LTS on my windows pc. I added the efi entries on my main drive containing windows and wanted to dual boot, such that grub loads on default and I can select whether I want to boot into Ubuntu or Windows. But it boots to windows by default.

I tried changing the boot order with efibootmgr and changed the first priority to Ubuntu Grub, but on restart, it boots to windows, the order reverses back.

I tried the same in Windows with bcdedit with the same result.
I suspect it is something to do with my motherboard, which forces me too boot to Windows. Renaming the windows EFI file leads to failure to boot. The only way to boot to Ubuntu is with the f11 boot menu. I can also boot to Windows from the Grub Menu. But the Grub menu won't show up by default.

The bios also has a weird drive selection, with no proper names. Boot priority lists stuff like UEFI USB Hard Drive, USB Hard Drive, CD ROM, Network Drive, etc, instead of the actual drive names. The drive with windows shows Windows Boot Manager, but no such luck with Ubuntu.

I am very new to OS flashing and BIOS stuff, and am very scared to brick my PC. But I still want to have the grub menu by default. I have listed my specs below, Any help would be appreciated.

OS:

1. Ubuntu 24.04.4 LTS on 100GB partition of a 250GB HDD

2. Microsoft Windows 11 22H2 on a partition of a 500GB SSD

I just added KDE to Ubuntu. Now it is asking for my ID to open. I used the ID and password I used for Ubuntu, but it will not open. I did some research, and it seems to be a regular problem. I can't get into the program to do anything. How do I fix it?

This is an involved question that cannot be answered with a 3 second Google search. No, setting environment variables in a shell script are not the answer.

In secured environments, the use of RPATH is bordering on strictly forbidden. Qt, which begat CopperSpice which begat Ls-Cs, had a .conf file that never worked. The hack in the Qt world is to use a DeployQt script which basically dumps all of the libraries and plugins into the same directory as the executable. This is most definitely a hack.

In the 0.2.1 branch I've been experimenting with how to fix this. It's primarily an issue when you wish to perform a local library build to build and link example or other programs against. This local directory tree is not in the system library path, nor should it be. I've seen some developers force local builds into .local/include and .local/lib which isn't that great either.

After a build of library, the .conf file looks as below.

[Paths]
Prefix = /home/developer/github_projects/LsCs_local_release
Headers = include/LsCs
Libraries = lib/LsCs
Binaries = bin
Plugins = lib/LsCs/plugins
Data = share/LsCs
Translations = share/LsCs/translations

One of the biggest issues is the plugins directory is a tree unto itself. When one builds a Debian or RPM package and installs that into system directories all is bright and beautiful, as long as you don't need to test a local library or plugin via the .conf file.

GNU knew dlopen wasn't good. It gave us libtool long ago. Built with LTDL_DLOPEN_DEPLIBS you can use lt_dlinsertsearchdir (const char *before, const char *search_dir) to insert paths from your .conf, using lt_dlopen() or lt_dlopenadvise() to find library files.

What isn't documented anywhere I can find is how to stop Ubuntu (any version) from attempting to use dlopen() for initial library loads of executables built against a local (development) library build.

Is there a way around this? RPATH really is a bad thing per most secured environments. They are okay with a .conf where they can check things, but RPATH is hidden in the binary which means (to them) if it is somehow tweaked or one of the directories it is pointing to gets linked to something nefarious, they can't tell until it is too late.

Has anyone found a way to do this?

I even used Claude Code to help create an optimized version of Chrome. I've installed drivers, flipped many chrome://flags, and turned off an on hardware acceleration.

During a brief period of trying Firefox, I experienced the same thing.

Restarting daily just cannot be life with Ubuntu! Can someone help me out here?

I've been trying to sort this myself, but I am now stuck.

I've rebooted my router

Windows dual boot on same drive. The machine works OK, as well as all other devices in the household work OK.

This is a few days old completely fresh install of Ubuntu which has been been working OK up until a few hours ago (10th Sept 24 AM).

My main laptop runs Ubuntu 22.04.1 on an Intel Core -7-11370H CPU @ 3.300GHz. I usually use it to code and play games, but whenever I run the laptop, it just randomly fluctuates from 4.0 GHz to 800 MHz. The fans also tune up all the way. At first this seems like a thermal throttling issue, but after look at my CPU temps, they are way below 70C.

When it is not under full load, it seems to be overusing one CPU core and not utilizing the others:

And under maximum load:

cpufreq-info output:

  driver: intel_pstate
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency: 4294.55 ms.
  hardware limits: 400 MHz - 4.80 GHz
  available cpufreq governors: performance, powersave
  current policy: frequency should be within 400 MHz and 4.80 GHz.
                  The governor "powersave" may decide which speed to use
                  within this range.
  current CPU frequency is 400 MHz.

I also checked if the system-governer was set to performance, which is was:

performance

Cannot also be a thermal throttle because the data the sensors shows me makes it clear that the temps are super-low (output of sudo sensors):

Ubuntu MATE 20.04.3 LTS 6600XT GPU

replacing my old gpu with a new one and having a real hurdle.

downloaded the proper 21.40.2 for ubuntu 20.04.3 file here

Followed directions here

even got the pro package from here and followed the extraction method

ran update, upgrade distro, reboot, and.... nothing. Plugging hdmi into gpu doesn't output video.

i checked software & updates and proprietary drivers are checked, when i check additional drivers, it shows nothing.

running

  lspci -k | grep -A 2 -i "VGA"  

shows that the system recognizes i have the proper gpu in place

running

  sudo ubuntu-drivers devices 

returns nothing

running amdgpu-install and amdgpu-pro-install output:

but when i check with dpkg -l amdgpu amdgpu is confirmed but amdgpu-pro is not.

i've updated and upgraded and rebooted and i can't get the gpu to activate and it still does not show up under additional drivers.

any thoughts?

I have little linux experience and am wondering if anyone can help me with this? I have a Realtek 8812AU / 8821AU USB wifi dongle and am needing the drivers for it so I don't have to be tethered to my router. I've tried using make, git clone, and DKMS to clone repos and build the drivers, and when I've gotten some to show up and be selected in Ubuntu's Software & Updates additional drivers panel, the adapter still never works (when it is in use a blue light flashes). How can I get it to work?

Here is some info:

I have 2/3 monitor setup

nr #1 - 5120x2160 (21:9) AKA "5K"

nr #2 - 1920x1080 (16:9)

nr #3 - 1920x1080 (16:9) - connected and used only occasionally

Display setup:

It`s messy. Default resolution detected by system for #1 is 3440x1440. After switching to the full native resolution of "5K" it looks way better but UI elements and text are uncomfortably small.

When I change scaling for #1, #2 is changing as well. Also, I'm glad to see Fractional Scaling build in Gnome Display Settings, but it's buggy in my case:

#1 set to 150% scaling:

As you can see in this screenshot (although it doesn't reflect the problem 100%) its messed up. On #2 I can go only to half the height of the screen where the top bar is being displayed. The wallpaper is messed up. It's unusable.

Wayland is unavailable for me since I use Nvidia GPU. I wouldn't like to lower my resolution on #1 as a workaround.

How to set up #1 to 200% while keeping #2 (and #3 at some occasions) at 100%?

I'm using an ubuntu:xenial spawned container in LXD/LXC and can't work out why it keeps booting with an IPv6 link local address (fe80::). If it's at all relevant, I'm also using Xenial as the container host.

There are no IPv6 entries in /etc/hosts. There are no IPv6 addresses defined in any of /etc/network/interfaces*.

I've added net.ipv6.conf.*.disable_ipv6=1 to /etc/sysctl.conf and although this works to clear the assigned link local addresses when you run sysctl -p after boot, it doesn't seem to run during boot so the container starts with the IPv6 link local addresses assigned.

I've added ipv6.disable=1 ipv6.disable_ipv6=1 to GRUB_CMDLINE_LINUX_DEFAULT inside the container in /etc/default/grub.d/50-cloudimg-settings.cfg but that seems to do nothing. This makes sense as there's no update-grub2 inside these containers so presumably Grub plays no part in the container startup process. I haven't managed to work out how the container decides what to try and enable or disable inside it's view of the kernel, otherwise I would try putting a setting there.

It seems I'm missing some fundamental understanding of what's causing these link local addresses to get assigned during container boot.

Any ideas or suggestions?

_{Please don't waste time preaching how I should learn to love IPv6. My employer is not going to use IPv6 for a long time as there is so much legacy network connected equipment that is extremely expensive and will never work on IPv6 that you would be wasting your typing.}

I am attempting to setup PCI GPU passthrough for a Nvidia GTX 1080ti FE on a Dell R710 server for computing. I am trying to pass it through to a Windows 7 VM using VFIO and OVMF on the VM, but I have to be missing something as the device causes Windows 7 to fail to boot once I remove all devices and attach the GPU. It is at least passing through the display through the GPU which is a start, but not complete. I have my VM XML listed in the below Pastebin. I attempted to use this step-by-step: https://medium.com/@calerogers/gpu-virtualization-with-kvm-qemu-63ca98a6a172

I have the listing below in my grub file to use for the passthrough on the devices.

GRUB_CMDLINE_LINUX_DEFAULT="nouveau.blacklist=1 vfio-pci.ids=10de:1b06,10de:10ef intel_iommu=on vfio_iommu_type1.allow_unsafe_interrupts=1"

I then verified that the devices are using the VFIO drivers:

VirtServer:~$ lspci -nnk
07:00.0 VGA compatible controller [0300]: NVIDIA Corporation Device [10de:1b06] (rev a1)
Subsystem: NVIDIA Corporation Device [10de:120f]
Kernel driver in use: vfio-pci
Kernel modules: nvidiafb, nouveau
07:00.1 Audio device [0403]: NVIDIA Corporation Device [10de:10ef] (rev a1)
Subsystem: NVIDIA Corporation Device [10de:120f]
Kernel driver in use: vfio-pci
Kernel modules: snd_hda_intel

What am I missing in my config that would be causing these issues?

I'm trying to install Ring and have run into dependency problems. I have no idea how to fix this. Would you have any ideas about how to approach this problem? I have attempted sudo apt-get update, sudo apt-get autoremove and sudo apt-get -f install but nothing seemed to help.

Q: How can I resolve this problem? "npm cache clear didn't" helped. The FS is mounted with noexec. System is up-to-date.

After fresh install of Lubuntu 13.04 I did

sudo apt-get install tightvncserver
sudo apt-get install xrdp

Now when I log in with remote desktop client from Windows or Ubuntu, I get black and white mesh screen. I followed various help forums like this one, but nothing worked!

I'm wondering why Shift + Arrow Key result in one of the A, B, C or D letters.

Why not other letters? Why any letter at all?
