Cannot Install Ubuntu server 20.04.4 on a 705 G4 Mini Desktop pc (HP brand) https://askubuntu.com/questions/1565402/cannot-install-ubuntu-server-20-04-4-on-a-705-g4-mini-desktop-pc-hp-brand

I am trying to Install Ubuntu server 20.04.4 on a 705 G4 Mini Desktop pc and I cannot because whenever I get to the Guided storage configuration i get the message "Block probing did not discover any disks. Unfortunately this means that installation will not be possible".

I have searched the issue and discovered other posts saying I have to reconfigure the RAID, but when I boot up the BIOS, the settings the posts point me to do not exist, and I have checked every part of the BIOS for any relevant setting and came up empty.

I also found that a mounted file might be causing the error, so I used the given solution which was to boot up the terminal and run:

losetup -d /dev/loop0

umount /isodevice

but that gave me a message saying that there were no mounted files so I think that isnt the problem either.

I have no idea what to do or if these two items are even compatable (research says they should be) and would like any insight into the problem.

Thanks, William

Ubuntu Studio - Native Instruments https://askubuntu.com/questions/1565401/ubuntu-studio-native-instruments

I'm using Ubuntu Studio, now with Ubuntu Pro enabled... I just rebought Native Instruments awhile ago, and Windows isn't affordable since I only get $62 a month or less from SSI in a nursing facility mental health place... I splurged to take money I didn't realize I had onto Native Instruments. I also have full fledge FL Studio. I do not want to get a Virtual Machine to install this software on Windows, as it is no longer a secure option for me. My enemies have already torn it a part, and they even try messing with Ubuntu Studio, to no avail for them. I've been hacked numerous times, but only through my own system, as noted after a 6 month crap situation inside a mental hospital where my phone and laptop weren't running. They could not do any hacking then. I'm just curious on how to run

Native instruments and FL Studio in Ubuntu Studio. If I have to buy something to make it run correctly, or is there a method to WINE or otherwise I'm not familiar with? Because last time I used linux was in 2009 on an ASUS EeePC 4Gig Surf. And my first time was because the 32bit AGP DIamond graphics card had zero driver support in XP 32bit.

This happens to be the ongoing problem... Windows stops supporting hardware, gets infected, then is no longer useable.

I tried running Native Access, but it has so many processes that need to also be verified with an okay, and it doesn't work right to try so.

openshot 3.5 not running https://askubuntu.com/questions/1565398/openshot-3-5-not-running

I just installed openshot 3.5 from openshot ppa. (ubuntu 24.04)

$ sudo add-apt-repository ppa:openshot.developers/ppa
sudo apt update
sudo apt install openshot-qt

$ openshot-qt --version
3.5.0-dev

I launch it and get this error:

"Version 0.6.0 is required, but 0.3.2 was detected. Please update libopenshot or download our latest installer."

Can't find the library:

$ sudo apt install libopenshot

Window animations are broken! https://askubuntu.com/questions/1565397/window-animations-are-broken

I'm on 24.04.4 LTS, and window animations randomly stopped working, after I unplugged my hdmi cable for 10 hours.
I plugged it back in in the morning and there was no animation at all.
This is all I know.
I have tried rebooting

Here is some more information, I think.

Window animations, as in, geany effects. Closing a window has an animation. Instead of immidiately dissapearing, the window fades. clicking "show apps" has a fancy animation as well. The apps list comes up from the bottom of the screen, instead of just appearing

None of these are working on my pc.

6.17.0-20-generic I am running my display like this: pc, soundbar, monitor. Graphics card: gtx 980 I have checked accesibility. reduce animations is off. I have checked the terminal redout of that same setting. Something like "window-animations-enabled:" and it was set to true

UPDATE Upon running the command ununtu-drivers install, my pc is not booting. (Shows white screen with text "oh no something has gone wrong. a problem has occurred and the system can't recover. please contact a system administrator”)

Wifi adapter not found - Ubuntu 24.04 https://askubuntu.com/questions/1565386/wifi-adapter-not-found-ubuntu-24-04

My PC is a Dell Precision m4800. I have just installed Ubuntu on my machine, however the Wi-Fi is not working. It says: No Wi-Fi adapter found. I am new to Linux, and don't know how to diagnosis the issue.

I tried running the following commands.

sudo apt install linux-firmware  
sudo apt install broadcom-sta-dkms  

Then I rebooted my system, but it is not working. I am not sure if I can use this command, or if I should run another command that is compatible with my PC and corresponding Wi-Fi driver.

Nvidia GeForce GTX 1080 driver issues https://askubuntu.com/questions/1565381/nvidia-geforce-gtx-1080-driver-issues

I am completely new to Linux dist. coming from Windows 10. I have installed Ubuntu and installed Steam. Almost all the games in my library are not running after installation.

I actually have a dual GPU in my desktop. Both are connected to each other by a card called 'SLI'. First GPU ensures imaging (rendering video). Second GPU ensures mathematical calculations.

I even installed the latest nvidia driver that is listed on the official ubuntu website. I tried via ChatGPT prompts to find a solution but nothing helped.

Can someone please provide support? I am very desperate.

I have installed Ubuntu 24.04.4 LTS Desktop.
I installed the driver with:

sudo ubuntu-drivers install nvidia:535

Further info:

  • Version of currently running driver:
    • NVRM version: NVIDIA UNIX x86_64 Kernel Module 535.288.01
How to unset GNOME Builder as default editor? https://askubuntu.com/questions/1565311/how-to-unset-gnome-builder-as-default-editor

I ran flatpak install org.gnome.Builder on Kubuntu 25.10 before modifying and compiling a GTK3 app. Now most source code file extensions open in GNOME Builder. I'd like KDE Kate back as default to recover my preferred color scheme, custom keybinds, and VI mode. Uninstalling, then reinstalling when I want to work on GTK3 apps, is too inefficient.

Someone said to check xdg-mime query default text/plain and kcmshell6 kcm_componentchooser to set the default text editor, but it's still org.kde.kate.desktop as preferred. I was using a workaround on each of .{css,pl,sh}, right-clicking in Dolphin then going into Properties and changing the "Open with", but today I clicked on a .c file and decided I've had enough.

I'm about to split and loop through grep MimeType= /var/lib/flatpak/exports/share/applications/org.gnome.Builder.desktop to run xdg-mime default org.kde.Kate.desktop "$x", but this might not persist if a GNOME Builder update adds more MIME types. Which command can permanently prevent any specified application from being the first entry in Dolphin's "Open with" list and used by xdg-open?

Monitor loses signal while playing DirectX 12 and Vulkan games https://askubuntu.com/questions/1565267/monitor-loses-signal-while-playing-directx-12-and-vulkan-games

While playing games on Kubuntu 25.10 and 26.04* (Both fully updated at the time of testing), my primary monitor, the monitor I'm playing on, will lose signal and will require me to turn it off and on again before working. The game still runs while this is happening however and resumes after a power cycle.

So far I've tested:

  • Runescape: Dragonwilds - Steam (Proton) version - DX12 and Vulkan
  • Cyberpunk 2077 - Steam (Proton) version - DX12

Display configurations I've used:

  • 2560x1440
  • 100% scale
  • Refresh Rate: 144hz
  • Every option for Adaptive Sync
  • HDR on and off
  • Every option for Color Accuracy
  • Not a replica of a display
  • Screen Tearing on and off

Kubuntu (Wayland) microphone detected by PipeWire but browsers don’t create input stream (Realtek ALC257, PipeWire 1.2.7) https://askubuntu.com/questions/1563887/kubuntu-wayland-microphone-detected-by-pipewire-but-browsers-don-t-create-inpu

I’m facing a persistent microphone issue on Kubuntu under Wayland. The hardware and ALSA layer appear to work correctly, but browsers fail to create an input stream.

I would appreciate guidance on structured debugging.


System Information

  • Distro: Kubuntu (Plasma)

  • echo $XDG_SESSION_TYPEwayland

  • Audio stack: PipeWire 1.2.7 + WirePlumber

  • Chipset: HDA Intel PCH

  • Codec: Realtek ALC257

Output of:

cat /proc/asound/cards
0 [PCH]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0x6001140000 irq 171

Problem Description

  • During calls, people cannot hear me.

  • I can hear them perfectly.

  • Happens in Chrome, Firefox, and Brave.

  • Sometimes browser shows “Mic not found”.

  • Happens with and without headphones.

  • Restarting PipeWire sometimes temporarily fixes it.

  • Issue is inconsistent.


Current PipeWire State

Output of:

wpctl status

Audio devices:

  • Built-in Audio detected

  • Sink and Source both present

  • Default sink and source correctly set to built-in analog stereo

However, when Chrome is open, under “Streams” I only see:

output_FL
output_FR

There are no input_FL / input_FR streams created for Chrome.

So:

  • ALSA sees capture device

  • PipeWire sees source

  • Default source is correctly configured

  • Browser does not create input stream


What I’ve Tried

  1. Restarted services:

    systemctl --user restart pipewire pipewire-pulse wireplumber
    systemctl --user restart xdg-desktop-portal
    
    
  2. Verified capture device exists:

    arecord -l
    
    
  3. Verified duplex profile enabled (Analog Stereo Duplex).

  4. Set default sink/source manually:

    wpctl set-default <sink-id>
    wpctl set-default <source-id>
    
    
  5. Checked in pavucontrol:

    • Mic visible

    • Not muted

    • Volume normal

  6. Disabled ALSA power saving:
    Created /etc/modprobe.d/disable-hda-powersave.conf with:

    options snd_hda_intel power_save=0 power_save_controller=N
    
    

    Rebuilt initramfs and rebooted.

  7. Verified xdg-desktop-portal and xdg-desktop-portal-kde are installed.

None of these resolved the issue permanently.


Observations

  • Hardware appears functional.

  • ALSA layer is functional.

  • PipeWire source node exists.

  • Browser does not create capture stream.

  • Restarting services sometimes restores mic temporarily.

  • System is running under Wayland.

How to use opencv-python on WSL2 Ubuntu20.04 https://askubuntu.com/questions/1379311/how-to-use-opencv-python-on-wsl2-ubuntu20-04

I have just installed a Ubuntu-20.04 on WSL2. And I installed a miniconda env with python 3.7, and then I installed opencv-python by "conda install opencv". But when I try the simplest cv2.imshow, it complains below:

cv2.error: OpenCV(3.4.2) /tmp/build/80754af9/opencv-suite_1535558553474/work/modules/highgui/src/window.cpp:632: error: (-2:Unspecified error) The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function 'cvShowImage'

By the way, I can show plotting window by matplotlib.pyplot after I installed a VcXsrv and export DISPLAY=host_ip_in_wsl2:1.1. And I also make my GPU works after installed Windows 10 November 2021 update, CUDA driver for WSL2, and CUDA toolkit 11.0. I can get Tensorflow 2.4.1 working well with GPU. I can compile darknet with GPU and use it for YOLO v1.

I googled some. They say uninstall opencv and reinstall from channel menpo can do it. But this post is 5 years ago and not for WSL.

I also saw some posts demonstrate a tedious procedure to compile opencv-python from source.

So, how to use opencv-python on Ubuntu-20.04 of WSL2? Easy approaches like "conda install ..." or "pip install ..." is preferred. Compiling from source is also acceptable.

192.168.0.219:/volume1/NAS_Andrew /mnt/nas nfs nofail,nconnect=16,rsize=32000,wsize=32000,hard 0 0

This resolves to the following entry in /proc/mounts when mounted:

192.168.0.219:/volume1/NAS_Andrew /mnt/nas nfs4 rw,relatime,vers=4.1,rsize=32000,wsize=32000,namlen=255,hard,proto=tcp,nconnect=16,timeo=600,retrans=2,sec=sys,clientaddr=192.168.0.220,local_lock=none,addr=192.168.0.219 0 0

The problem is that when I am writing a large file to the NFS mount, all other filesystem operations within the mount hang.

For example, if I run the following in terminal 1:

time dd if=/dev/zero of=/mnt/nas/testfile bs=16k count=128k

and then run ls -la in terminal 2; the ls process hangs until the dd write is complete.

I believe the issue is limited to the local NFS client because if I run the same ls -la on another server that also has the NFS share mounted - it runs without any hang or issue.

I'm hoping that someone can shed some light as to why the write operation is blocking. I tried setting nconnect=16 in an effort to increase the tcp connections and allow more than one operation - however this did not work and I suspect nconnect may be limited to cases where multiple network interfaces are available.

I am running Ubuntu 20.04.3 LTS.

Any input is greatly appreciated.

How to stop using the HWE kernel and go back to the GA kernel? https://askubuntu.com/questions/1306358/how-to-stop-using-the-hwe-kernel-and-go-back-to-the-ga-kernel

I need my Ubuntu to be stable as I rely on it heavily for my business and uni. I needed to update my google cloud sdk so I run sudo apt upgrade as I have done for the last year with no issues. After reboot, my dual screen monitor stopped working and the main display freezing and I lost access to my virtualbox.

I am losing about $50 an hour while this is broken so I am happy to pay some one $100US an hour so I can have a stable system again. Is it possible to stop Ubuntu from upgrading the kernel itself?

Really angry actually that Ubuntu would release such a broken and untested kernel on an LTS system.

how to run a service a non-root user completely? https://askubuntu.com/questions/1140332/how-to-run-a-service-a-non-root-user-completely

I am trying to run an application (code-server) as a sudo user. This application is basically allowing me to run Visual Studio Code online. I created the service file as below: (vsc.service)

[Unit]
Description=Running Visual Studio Code Online

[Service]
User=dev001
Group=dev001
WorkingDirectory=/home/dev001/projects
Type=simple
ExecStart=/usr/bin/sudo /usr/bin/vsc.sh

[Install]
WantedBy=multi-user.target

As you can see that the service file has the user and group information.

Here is the script I want to run as a service (/usr/bin/vsc.sh)

cd /home/dev001/projects
code-server -p 80 --allow-http --password somepassword

It runs fine but the problem is that the user who is running the process is still kept as root, but working as dev001. here is the screenshot of the terminal access via the running service:

vscode terminal window screenshot

Please help me if you have any solution to the problem.

Edit 01:

I have taken the nginx help to do a port forward (reverse proxy) to resolve the issue, until code-server gets matured and has the daemonised support for running directly on port 80 or 443. The one benefit I got with this approach is that I am able to install the letsencrypt ssl. so no my environment is all running as I needed to be. There are other issues thought, but they are not related to this thread.

Ubuntu can't boot, access rescue mode or reinstall https://askubuntu.com/questions/1139350/ubuntu-cant-boot-access-rescue-mode-or-reinstall

Since a few days ago, I can't boot my computer on ubuntu, I can't even access rescue mode or boot on a liveusb to try to reinstall my os. Windows is booting fine however.

On a regular ubuntu boot some services fail to start and at some point, the boot process simply stops enter image description here

When I try to start rescue mode or boot with liveusb, I have other messages like AMD-VI: Completion-Wait loop timed out and iommu ivhd0: Event logged [IOTLB_INV_TIMEOUT device=1b:00.0 address=0x40e596610] or Kernel panic - not syncing: corrupted stack end detected inside scheduler enter image description here enter image description here

I managed to access my terminal, update-grub didn't help, but when I typed sudo apt update I had E: Error reading the CPU table. /usr/share/dpkg/cputable was missing, I copied a version of the file I found in /snap/core18/941/usr/share/dpkg/cputable and now I have E: Cannot find dpkg tuplet or triplet table.

DNS cannot resolve hosts https://askubuntu.com/questions/897270/dns-cannot-resolve-hosts

But I cannot run the update to fix the issue because it can't use DNS to conduct the update. Is there any documentation out there on how to get the DNS working again so i can run the update and fix the issue? I have tried changing the DNS server and everything and nothing is working.

Freezing of screen on Ubuntu 16.04 https://askubuntu.com/questions/801586/freezing-of-screen-on-ubuntu-16-04

I have recently installed Ubuntu 16.04 and it seems to freeze randomly. I tried to check out the the solutions at Ubuntu 15.10 and 16.04 keep freezing randomly but on installing these kernels, I got a kernel panic at boot, so I furthur looked for solutions at Ubuntu 16.04 constantly freezing leading to kernel panic but couldn't figure out how to resolve the problem. Can anyone tell me which exact kernels to install so that both issues (kernel panic and random freezing) is resolved? The kernel that came preinstalled with 16.04 was 4.4.0-21-generic and these are some extra details:

Distributor ID: Ubuntu

Tell me if I need to provide any other details.

Live CD kernel panic https://askubuntu.com/questions/7256/live-cd-kernel-panic

I'm an Ubuntu user since Hardy Heron, and even in other distros I've never been through such thing. I can't install Ubuntu 10.10 on my notebook, because I simply can't even start the Live CD. I always get the following message:

Kernel panic - not syncing attempted to kill init!

See the complete message:

                                Ubuntu 10.10
