AMD Radeon 780M generates constant device notification sounds on battery (Ubuntu 24.04) https://askubuntu.com/questions/1565802/amd-radeon-780m-generates-constant-device-notification-sounds-on-battery-ubuntu

I have an ASUS Vivobook 18 M1807HA with an AMD Radeon 780M integrated GPU running Ubuntu 24.04 (kernel 6.17.0-20-generic).

Problem

When running on battery power only, my laptop generates constant USB device connection/disconnection sounds (the "ding-dong" notification) every 60-90 seconds. The desktop icons sometimes refresh/update when this happens.

This does NOT happen when the AC adapter is plugged in.

What I've tried

I've investigated extensively and found that:

  1. Running sudo udevadm monitor shows constant drm/card1 change events:

KERNEL [1192.228486] change /devices/pci0000:00/0000:00:08.1/0000:03:00.0/drm/card1 (drm) UDEV
[1192.261376] change /devices/pci0000:00/0000:00:08.1/0000:03:00.0/drm/card1 (drm) KERNEL [1231.346665] change /devices/pci0000:00/0000:00:08.1/0000:03:00.0/drm/card1 (drm) UDEV
[1231.370399] change /devices/pci0000:00/0000:00:08.1/0000:03:00.0/drm/card1 (drm)

  1. Setting amdgpu.runpm=0 in GRUB does not resolve the issue
  2. Disabling WiFi does not resolve the issue
  3. power_dpm_force_performance_level remains unchanged during events
  4. No error messages appear in dmesg

Workaround

Disabling system event sounds stops the audible notification:

gsettings set org.gnome.desktop.sound event-sounds false

However, the underlying issue (constant drm change events) persists.

Questions

  1. Is this a known bug with the AMD Radeon 780M on battery power?
  2. Has anyone else with recent AMD Ryzen AI laptops experienced this?
  3. Is there a proper fix beyond disabling notification sounds?

I've already reported this as a bug to the AMD DRM developers, but I'm curious if others in the Ubuntu community have encountered this issue.

Many Windows Steam games (mostly multiplayer shooters) crash on startup https://askubuntu.com/questions/1565801/many-windows-steam-games-mostly-multiplayer-shooters-crash-on-startup

I am about 3-4 weeks new to Ubuntu, downloading it in a bid to not install Windows 11, and for those weeks I've been trying my hardest to get my Steam games working on this device, to no avail.

Some games do work. I was able to get PEAK working on my computer after a LOT of setup, and single player games/really old point and clicks (e.g. Dave the Diver, Sam and Max Hit the Road, IHNMAIMS) work perfectly (though this could just be because of how simplistic they are).

Games such as Deadlock, Marvel Rivals, and The Outlast Trials, more high-fidelity games with a high amount of multiplayer however don't boot up. The best I've gotten is Deadlock, which I've been able to get the launch screen up until it crashes. Unfortunately all the answers I've seen on this website are either not working, or are simply too complex for my newbie brain to comprehend. I have gamemode installed and configured, GeProton is installed and applied to all desired games, ProtonTricks is installed, though I have no idea idea how to use it, and my Driver package is nvidia-driver-535.

Here is the last terminal log I recorded with Deadlock, gained by running Steam through Terminal. If I had to guess what the problem was, it would be the system is not recognizing libgamemode.so, despite it being on the device.

HP OMEN 16 fan control not working on Ubuntu (ec_sys permission issue) https://askubuntu.com/questions/1565799/hp-omen-16-fan-control-not-working-on-ubuntu-ec-sys-permission-issue


Laptop: HP OMEN 16-wd0xxx
CPU: i5-1340H
GPU: RTX 4050
OS: Ubuntu 22.04 / 24.04

Problem:
Fan speed is not controllable on Linux. Fans either run incorrectly or cannot be accessed.

What I tried:

* sudo modprobe ec_sys write_support=1
  → Error: "Operation not permitted"

* Installed lm-sensors → detected sensors but no fan control

* Tried fancontrol → no pwm control available

Expected:
Ability to control or at least read fan speed.

Actual:
EC access seems blocked; fan control unavailable.

Logs:
(paste output of dmesg, sensors, lsmod)

Additional info:
This laptop works fine on Windows (fan control available via OMEN software), suggesting firmware/EC restriction.
Hi so I forgot my password for my lenovo carbon with ubuntu installed I then did a secure wipe and now I cant get the usb to install the ubuntu os https://askubuntu.com/questions/1565798/hi-so-i-forgot-my-password-for-my-lenovo-carbon-with-ubuntu-installed-i-then-did

Ubuntu 24.04.04 installation fails on Acer Aspire 5750, Broacom wireless chip problem https://askubuntu.com/questions/1565792/ubuntu-24-04-04-installation-fails-on-acer-aspire-5750-broacom-wireless-chip-pr

On starting the Ubuntu 24.04 installation an almost unreadable message appears on the screen saying:

Firmware file b43/ucode30_mimi.fw not found. 
You must go to https://wireless.docs.kernel.org/en/latest/en/users/drivers/b43/developers.html#list-of-firmware 
  and download the correct firmware for this driver version. 
Please carefully read all instructions on this website.

There is a table on the mentioned page. In the column version of wl. wl I guess wireless are 12 numbers with links listed. They are links to download the driver I guess, however I don't have any information about the meaning of those numbers! On the following page, some Acer notebooks are mentioned, less Acer Aspire 5750!

In short I don't have a driver for the Broadcom wireless chip! At the "repair café" where the customer brought the laptop, I could install Ubuntu 24.04.02 without wireless, hence without internet of course! I took the laptop home and tried an completely new installation being connected to the internet by a LAN cable. This was worse! The installation failed completely telling me in the error message: "We are not sure what kind of error happened, try to install again!" Which of course doesn't work and the partially installed system is not bootable at all. Two kinds of sending the error report are provided. One "Send problem" which doesn't work, and a second one by: sudo ubuntu-bug ubuntu-desktop-boostrap, which doesn't work either.

Can someone tell me where to get this damned Broadcom driver, the correct one for the chip in this Aspire 5750 Notebook and I need to know whether I could place the driver on the USB stick which I used to do the Ubuntu installation?

How do I mount my 8TB hard as my Videos folder with rw permissions? https://askubuntu.com/questions/1565789/how-do-i-mount-my-8tb-hard-as-my-videos-folder-with-rw-permissions

I am having trouble getting my 8TB hard drive to mount permanently. I have already been able to mount it as a folder. I just cannot get it to have rw permissions in /etc/fstab. The rw flag does not work. I have tried rebooting and still no joy. Is there something I am doing wrong. here is my /etc/fstab.

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a device; this may
# be used with UUID= as a more robust way to name devices that works even if
# disks are added and removed. See fstab(5).
#
# <file system>             <mount point>  <type>  <options>  <dump>  <pass>

UUID=f61af190-c1f4-4f17-89b9-7686a7c2091c /home/justin/Videos ext4 rw,defaults 0 2 - It mounts OK. I am just wondering if I have the rw permissions in the wrong place.

I have already used AI that did not work, and I tried searching for it on Ask Ubuntu to no avail.

How to robustly connect to Android phone with KDEConnect/GSConnect when travelling between different networks, just like Apple ecosystem? https://askubuntu.com/questions/1565782/how-to-robustly-connect-to-android-phone-with-kdeconnect-gsconnect-when-travelli

I use KDE Connect between my phone and laptop on my University WiFi. Very often, the IP address changes and the connection stops working. I have to manually find the IP of the computer with the command ip address and put it in my phone and connect manually. The same thing happens when I connect to a different network.

Is there any way to automate the connection process? AFAIK know Mac computers have some robust connection procedure with iOS devices.

I want to be able to do this for multiple computers with the same phone.

Need help running Steam games - Ubuntu laptop with Quadro T2000 https://askubuntu.com/questions/1565780/need-help-running-steam-games-ubuntu-laptop-with-quadro-t2000

I've followed many tutorials, and verified that my old-ish graphics card is compatible with Vulkan, but I still cannot get a Steam games (testing with Balatro) to run on my fresh Ubuntu 24.04 install.

I'm using Nvidia 580.126.09 drivers which is what it defaults to installing when I use ubuntu-drivers install but I have also tried every other one available (that I can find) which are 535.288.01, 570.211.01, and 590.48.01.

I'm trying to use Steam + Proton to play Balatro (a Windows game) on Linux, which according to ProtonDB should work. My best guess as to why it doesn't work has something to do with Nvidia drivers, which is why I listed the graphics card.

I broke my Windows 10/Ubuntu dual-boot machine. Need help to access the Windows 10 partition https://askubuntu.com/questions/1565779/i-broke-my-windows-10-ubuntu-dual-boot-machine-need-help-to-access-the-windows

My HP laptop has a single NVMe drive on it that I gave a 30GB partition for a new Ubuntu install. The goal was to have a dual-boot machine with Windows 10 being primary. The live CD/USB install of Ubuntu went well, but now I can't force a boot into the Windows partition.

I have tried boot-restore, but that caused an issue with GRUB not working right and making the Ubuntu install not accessible either. I have reverted back to a working Ubuntu install. I tried to fix the Windows 10 loader with a windows live USB, but it can't see the Windows partition. I have also tried a Hiren's Boot USB, but none of the tools there can see the Windows partition either.

What information do I need to share, or steps should I take? I really need to get access to the drive and don't want to wipe it.

Ports used on the security.ubuntu.com mirrors? Corporate firewal issue https://askubuntu.com/questions/1565776/ports-used-on-the-security-ubuntu-com-mirrors-corporate-firewal-issue

Having issues with running sudo apt update and sudo apt upgrade commands. These commands fail with an error E: Failed to fetch ... 403 Forbidden [IP: w.x.y.z 80], where w.x.y.z is one of these security.ubuntu.com mirrors: 91.189.92.24, 91.189.91.81, 91.189.92.23, 91.189.92.22, 185.125.190.83, 185.125.190.81, 91.189.91.82, 185.125.190.82 or 91.189.91.83.

The corporate firewall has a restricted list of open outgoing ports, where port 80 (HTTP) is open for traffic.

The failed issues are all related to packages that have current CVE notices; the rest of the packages fetched from the Ubuntu archive mirrors succeed.

To us, it looks like the initial request on port 80 is succeeding in reaching a security.unbuntu.com mirror, yet failing to fetch the packages from security.unbuntu.com the mirror. We suspect the actual package fetch is using another port not on the corporate firewall allowed list.

We need the full list of ports that security.unbuntu.com mirrors are using for package delivery.

Definitive camera fix for Dell XPS 13 9315 on Ubuntu 22.04 LTS https://askubuntu.com/questions/1565760/definitive-camera-fix-for-dell-xps-13-9315-on-ubuntu-22-04-lts

I'm going to publish a self-answer on how to properly fix the internal camera without breaking the audio stack.

In this guide I'll explain how to do it right because there are people out there that have suggested a solution either by the DKMS or by the development PPA from intel.

Both can work only under specific circumstances but will break sooner or later because do not take care of the root cause of the issue.

To give a bit of context Dell XPS 13 9315 with stock Ubuntu is at 20.04 LTS but during normal Ubuntu upgrades the camera breaks and upgrading to 22.04 did not fix it.

I don't have knowledge of this issue being addressed even in version 24.04 LTS. Moreover I don't recall a single Ubuntu upgrade issue-free in the last 10 years. So I can't recommend trying it to avoid following this procedure.

Sleep/Suspend function not working on Lenovo ThinkBook 16 G8 IRL https://askubuntu.com/questions/1565734/sleep-suspend-function-not-working-on-lenovo-thinkbook-16-g8-irl

Suspend/hibernate not working - no usable answers were provided, the only proposed solution does not work.

This is NOT a duplicate of "Computer does not resume from suspend". The computer does not sleep or suspend at all and answers in this thread are not relevant. The question I had asked before had no functional solutions.

This is NOT a duplicate of 24.04 doesn't sleep as that has an "answer" that I cannot downvote or delete as the "answer" doesn't work.

I have a brand new Lenovo ThinkBook 16 G8 IRL running Ubuntu 24.04.3. The computer has 32gb of RAM and 2 physical SSDs, one for a Win11 installation and the other for a fresh Ubuntu installation.

Sleep/Suspend works perfectly in the W11 environment, but not in Ubuntu. I have tested using Ubuntu versions 18 to 24, Mint Cinamonn 22 and Pop!_OS 22 and 24. They have all exhibited the same behavior.

The screen goes black, it looks like the machine tries to sleep, but then wakes up again within 5 seconds. This makes it impossible to use as a true laptop as I have to save all work and shut down the computer whenever I will travel with it - which is quite often.

This is not a problem of the computer not restarting or restoring from suspend, the computer does not enter suspend in the first place.

I agree the suspend command should work out of the box, so I'm not understanding this. I ran the below command and had the same effect - black screen for 3-5 seconds, then back to a login screen.

Swap is on and has plenty of space (32gb of RAM)

I have followed several recommendations and followed several directions.

There are no external devices plugged in

I have attempted to disable USB devices, use Gnome Tweaks to enable suspend, changed USB wake properties, but I had no luck.

Updates: Computer updated to 24.04.4 New dmesg added at the end Kernel updated to 6.17.0-20-generic

UPDATE: I noticed that the file /etc/initramfs-tools/conf.d/resume does not exist. In fact, the conf.d folder is empty.

BUG: DKMS Build Failure for Broadcom BCM4360 [14e4:43a0] on Ubuntu 24.04 LTS (Kernel 6.8) - Unpatched timer_setup https://askubuntu.com/questions/1565684/bug-dkms-build-failure-for-broadcom-bcm4360-14e443a0-on-ubuntu-24-04-lts-ke
  1. Environment & Hardware

Machine: Apple MacBook Pro 13-inch (Late 2013)

Network Controller: Broadcom Inc. and subsidiaries BCM4360 802.11ac Wireless Network Adapter [14e4:43a0]

OS: Ubuntu 24.04 LTS (Clean install, LUKS encrypted LVM)

Kernel Version: 6.8.0-45-generic

  1. Issue Summary No Wi-Fi connectivity post-installation. The proprietary Broadcom drivers (broadcom-sta-dkms / bcmwl-kernel-source) fail to compile via DKMS on Kernel 6.8 due to deprecated kernel API usage (specifically, the old init_timer function instead of the modern timer_setup).

  2. Troubleshooting Steps Performed To rule out user error, missing dependencies, or broken package states, the following steps were executed using a USB tethered connection:

Clean State & Prerequisites: * Performed a full system update (apt update && apt upgrade -y) bringing the system to Kernel 6.8.0-45.

Installed required build tools: sudo apt install build-essential linux-headers-$(uname -r).

Package Cleanup: * Forced removal of previously failed GUI installations to break the apt broken-install loop using: sudo dpkg -P --force-all bcmwl-kernel-source broadcom-sta-dkms

Cleared cache and verified system integrity (apt clean, apt --fix-broken install).

Driver Installation Attempt: * Attempted to install the community-maintained package: sudo apt install broadcom-sta-dkms (also attempted bcmwl-kernel-source).

  1. Result & Root Cause Analysis The DKMS build process fails consistently. Upon inspecting the make.log (/var/lib/dkms/bcmwl/.../build/make.log), the compilation aborts with the following critical error:

error: implicit declaration of function 'timer_setup'

Conclusion: The source code provided in the current broadcom-sta-dkms (and bcmwl-kernel-source) packages within the Ubuntu 24.04 noble repositories has not been patched to support Kernel 6.8. The proprietary Broadcom code still relies on the deprecated init_timer function, causing an inevitable compilation failure on modern kernels.

Request: Looking for information on whether a patched version of broadcom-sta-dkms for Kernel 6.8+ is planned for the 24.04 repositories, or if there is an officially recommended PPA/workaround for BCM4360 chips in the meantime, aside from manually patching the .c files locally.

project that models human organs and body movement in software [closed] https://askubuntu.com/questions/1565659/project-that-models-human-organs-and-body-movement-in-software

I am building a project that models human organs and body movement in software, with the goal of eventually mapping this to physical robotic parts.

I have a basic question:

In order to work on robotics on linux systems, what is the standard project structure for a ROS2 workspace? What would be an optimal way of setting up ROS2?

Thank you in advance for any suggestions.

I am a beginner with ROS2 but comfortable with Python. Any pointers to official documentation or working examples would be appreciated.

How can I run or use Paint 3D on Ubuntu 24.04? https://askubuntu.com/questions/1559591/how-can-i-run-or-use-paint-3d-on-ubuntu-24-04

I’ve recently switched to Ubuntu 24.04 and I really miss using Paint 3D especially for its easy 3D modeling and texture tools. I know it’s a Windows-only app, but I was wondering if there’s any reliable way to install or run Paint 3D on Ubuntu, maybe through Wine, Proton, or an alternative open-source tool that works similarly.

I checked the website (https://www.thepaint3d.com), but it seems there’s no native Linux version available yet.

If anyone has managed to get it running (even partially) or knows of a good Paint 3D equivalent for Ubuntu, I’d love some advice!

Thanks in advance for any help or recommendations.

How to disable temporary dynamic ipv6 addresses in Ubuntu 21.10? https://askubuntu.com/questions/1392414/how-to-disable-temporary-dynamic-ipv6-addresses-in-ubuntu-21-10

By default Ubuntu 21.10 (should be the same for 20.04) does generate temporary/privacy IPV6 addresses. I would like to disable this behavior in order to make my computer into a server, and to do so I would like to have an IPV6 address as stable as possible (notably to ease of process of configuring a DNS name without using DDNS, at least for the IPV6 address).

When looking at ip -6 address it looks like this:

    inet6 2a02:a03f:a0bb:abcd:ea4b:d152:592e:74da/64 scope global temporary dynamic 
       valid_lft 83659sec preferred_lft 69259sec
    inet6 2a02:a03f:a0bb:abcd:3c0d:e2ad:569e:2536/64 scope global dynamic mngtmpaddr noprefixroute 
       valid_lft 83659sec preferred_lft 69259sec

I want an autoconfigured permanent addresses like this (taken from a server in the same network, the address seem to have been generated using the modified EUI-64 algorithm):

    inet6 2a02:a03f:a0bb:abcd:211:32ff:fe59:76be/64 scope global dynamic 
       valid_lft 64840sec preferred_lft 50440sec

Please note I don't want to configure a static IPV6address!

That's why I ask this question today. Most Google searchs about this issue ends in nonsensical advice explaining how to configure a static IPV6 address. It's not the same thing than a permanent autoconfigured address. To generate those the OS must listen for the router to get the first 64 bits of the address and the complete the remaining bits with its MAC address.

Git push cannot write to object file - permission denied https://askubuntu.com/questions/1190377/git-push-cannot-write-to-object-file-permission-denied

I'm on a cloned repo and trying to push to my remote branch. Committing works just fine, however whenever I try to push I get this:

error: unable to write file ./objects/foo/bar: Permission denied

I own all files in the local repository and usually pushing works just fine, however after some time this error occurs and I cannot push.

The only thing resolving the issue, is to revert to the last commit on origin and try to find the file which is supposed to be causing trouble.

I then touch a new file and paste the contents from the old "broken" file. Sometimes this doesn't help either and obviously this is not a manageable workaround.

Speakers not working - Sunrise Point-LP HD Audio https://askubuntu.com/questions/1129013/speakers-not-working-sunrise-point-lp-hd-audio

I've looked at many similar questions but unfortunately the solutions didn't work for me. I have recently installed Ubuntu 18.04 and my speakers are not working nor are they are detected in the settings, they are actually listed as not available after running pacmd command. They are working fine on windows so the problem must be related to the compatibility with the driver in ubuntu, but I suppose there must be some settings to fix it. here ill pastebin what I get from the sinks list:

It looks to me like the headphones and the speakers are in the same sink, although as you can see it gives the speaker as not available. Anyone knows how to handle it? I've tried out myself but I'm starting to give up... Here are the details about my sound card

Wireless Card Restart on Ubuntu 18.04 https://askubuntu.com/questions/1077612/wireless-card-restart-on-ubuntu-18-04

I want to restart the network service in Ubuntu 18.04. I tried /etc/init.d/networking restart but the command didn't come out as expected. Can someone help resolve my issue?

Can't boot anything newer than Ubuntu 10.04: kernel panic https://askubuntu.com/questions/876878/cant-boot-anything-newer-than-ubuntu-10-04-kernel-panic

The latest version of Ubuntu that works for me (in legacy mode) is 10.04 with the 2.6.32 kernel. Starting with 10.10 and 2.6.35 it won't work. I'm also able to boot Trinity Rescue Kit with the 2.6.37.1 kernel.

What are the differences between thee two releases that could prevent me from running it?

Specs:

  • CPU: Intel Core i3-4010U
  • Chipset: Intel Haswell-ULT rev. 09
  • Southbridge: H8x/P8x rev. C1
  • RAM: 4GB DDR3 - HMT351S6EFR8A-PB
  • GPU: Intel integrated
  • HDD: SSHD Seagate ST1000LM014

Here's the complete lshw output : http://pastebin.com/FtQBtUxF

While booting anything later than 10.04 I get the following results ending in a kernel panic:

I had a 14.04 installation inside VirtualBox, and today I tried to update it to 16.04. It fails to boot after this. Selecting an older kernel version from the boot menu and/or recovery mode doesn't help. Do you have any ideas?

How to remove a package providing a service without stopping the service? https://askubuntu.com/questions/506507/how-to-remove-a-package-providing-a-service-without-stopping-the-service

I currently have the uwsgi Install uwsgi package installed. I would like to remove the package but leave the current uWSGI instances running. Is this possible?
