On MacBook A1278/A1322 running Linux, runtime charging (while the OS is on) stops working due to Apple SMC firmware overriding Linux ACPI driver commands (applesmc, sbs). Even with acpi_osi=!, acpi_enforce_resources=lax, and module reloads, charging only briefly boosts for ~10 seconds before stopping. Charging works normally when the system is powered off, but at a reduced current because firmware limits the charge rate.

ase convert the driver to use hwmon_device_register_with_info(). ➜ Desktop sudo dmesg | grep -i acpi [ 0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-6.17.0-12-generic

I’m having an audio issue on Ubuntu and I would really appreciate some help.

Here are my system details:

Hardware:

• Model: Apple Inc. MacBookPro13,1

• CPU: Intel Core i7-6660U

• RAM: 16 GB

• Graphics: Intel Iris Graphics 540

• Disk: 251 GB

Software:

• OS: Ubuntu 24.04.3 LTS (64-bit)

• GNOME: 46

• Windowing system: Wayland

• Kernel: Linux 6.17.0-14-generic

• Firmware: 529.120.1.0.0

Problem description:

Ubuntu detects the sound card, but I have no audio output and no microphone input.

Before installing Linux, macOS had working sound on this same machine, so I’m confident the speakers and mic are not physically damaged.

Diagnostics output:

I’ve been trying to fix this for the last 2–3 days using forum posts and YouTube tutorials, but nothing has worked so far.

I’m running Ubuntu 24.04 (GNOME) on a HiDPI laptop (14", 2880×1800) with display scaling set to 200% (2×). Native host applications scale correctly and behave as expected.

My laptop uses an Intel Core Ultra 5 225H processor, and Ubuntu 24.04 appears to be the only Ubuntu version that works reliably with this hardware. However, I need to work with ROS2 Humble, which officially supports Ubuntu 22.04. Since 22.04 does not work well on my hardware (wifi, display, and other hardware failures), I decided to use Distrobox to run Ubuntu 22.04 and ROS2 Humble inside a container.

While this setup works functionally, I’m facing persistent GUI scaling issues with applications launched from inside the container.

IssuesvObserved

1. All GUI applications launched from the Distrobox container behave as if the system is running at 1× scaling, even though the host is set to 2×:

2. GUI elements (icons, text, widgets) are extremely small

3. Cursor visibly shrinks when entering container windows

4. Happens consistently with ROS2 GUI tools such as:

   a. rqt

   b. rqt_graph

   c. turtlesim

The issue appears to affect all container GUI apps, not just ROS tools

Host GUI applications (Settings, Text Editor, etc.) behave normally.

Environment

1. Host OS: Ubuntu 24.04 (GNOME)

2. Hardware: HiDPI laptop (14", 2880×1800), Intel Core Ultra 225H

3. Display scaling: 200%

4. Sessions tested: X11 and Xorg

5. Container: Distrobox running Ubuntu 22.04

6. Applications tested: rqt, rqt_graph, turtlesim (Qt-based)

Is there a way to make it work reliably? Also, is this a known limitation or behavior when running GUI applications from containers (e.g., Distrobox) on GNOME with HiDPI scaling? Or should I use another method than containerization for my workflow? I am somewhat new to Linux so forgive if I have typed something stupid while describing my issue. I tried solving things using GPT but nothing helped.

I have found other questions about this command not working on the site but the errors emitted are not the same, at least in the several I looked at.

add-apt-repository fails when attempting to add repositories (several different ppas attempted)

The affected system is a virtual machine which started out as a clone of a physical PC. They have diverged over the years, and the physical PC does not have this problem.

I intend to deploy smartcontract using Minifabric blockchain (Hyperledger). I installed WSL2 (Windows subsystem for Linux), Ubuntu 22.04.5 LTS and Docker Desktop on windows 10. After installing prerequisites softwares/packages, I get Minimum API version error (its 1.39 and requires minimum 1.44) on Ubuntu Shell.

The installation steps are:

sudo apt update && sudo apt upgrade
sudo apt install curl git ca-certificates gnupg lsb-release
sudo apt install python3 python3-pip git -y

On "./minifab cleanup" command even it is again giving following API version error. This means the minimum API version mismatch errors are on both "minifab --help" and "minifab -cleanup". Below is the error and Docker version:

During software install via native gui software installer, crashed. Error message included firmware issue. Reboots to command line. Reboot recovery options did not fix the issue.

This system has run well for several years.

I am unable to install WINE using the standard instructions (https://gitlab.winehq.org/wine/wine/-/wikis/Debian-Ubuntu). I want WINE for two packages that do not exist on Linux, nor have equivalents.

Since WINE comes in four parts I narrowed it down to:

apt install wine-stable-i386

(Yes I have added the 386 architecture.)

And what I get is this many times for a lot of similarly named but different packages (though required versions change):

The following packages have unmet dependencies.
 kded5 : Depends: libqt5gui5 (>= 5.15.2~) or
                  libqt5gui5-gles (>= 5.15.2~) but it is not going to be installed

But libqt5gui5-gles is installed at the latest version:

root@me:~# apt install libqt5gui5-gles
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
libqt5gui5-gles is already the newest version (5.15.13+dfsg-1).
libqt5gui5-gles set to manually installed.
0 to upgrade, 0 to newly install, 0 to remove and 19 not to upgrade.

Note that previously libqt5gui5 was installed but I thought I'd uninstall and then re-install, but when I uninstalled, libqt5gui5-gles was automatically installed in its place (same errors).

For completeness, the 19 not to upgrade were elsewhere described as held due to phasing, which I understand is just slow release, and they are:

I know it's feasible to force upgrade but I didn't want to break anything and I don't think they are anything to do with WINE.

The window buttons to minimize or reduce master-pdf-editor 5 are missing.

Using TERMINAL, how do I SUCCESSFULLY uninstall nautilus completely, and aferwhich, how do I reinstall it SUCCESSFULLY - dependencies and all...?

Currently, I can copy, edit, etc files using terminal, edit using nano, etc., but nautilus seems to just want to crash so want to reinstall, not repair, it.

Maybe I have not found a way to get a good scan in Ubuntu. IMHO, a good scan file is high resolution and small. For the same resolution, smaller is better.

I have tried xsane, scanlite and scanpage, but the files are typically ginormous (bigger than a GB). Using Windows Fax and Scan in Windows 7, I set the resolution to 300 dpi and scanned a Windows 7 test printout. I get a nice looking image that weighs in at 132 Mb.

(I have not tried later Windows versions. I need Windows 7 for one application. I do not use Windows 7 for email or surfing.)

Until I find a good way to scan in Ubuntu, I will be dual booting into Windows 7 when I need to scan. Is there a way to scan in Ubuntu that I have not discovered?

I am running Ubuntu 24.04.3 LTS on my Dell XPS-13. After an update and subsequent restart my computer showed kernel panic error, so I booted into the old kernel (6.14.0-37-generic) to fix it.

I used

dpkg --list | grep linux-image

to identify the broken kernel (6.17.0-14-generic) and removed it via

sudo apt purge linux-image-6.17.0-14-generic linux-headers-6.17.0-14-generic

Subsequently I ran

sudo apt autoremove --purge

Here, I got the warning:

warning: while removing linux-modules-6.17.0-14-generic, directory '/lib/modules/6.17.0-14-generic' not empty so not removed

I looked up the directory and it is indeed non-empty.

So my questions are the following:

• Do I need to remove this directory to guarantee the proper functioning of my system?

• If yes, how?

• How can I update to kernel version 6.17.0-14-generic safely?

• As I removed 6.17.0-14-generic, only kernel version 6.14.0-37-generic is currently installed properly on my system. Does this pose a threat to my system?

Edit: I have since updated my grub and restarted my system.

Thanks for your help!

I'm running Ubuntu 25.10 on a notebook with 8 Gig RAM and a 1TB flash drive. After I've been on a long trip I like to keep the dash cam image files for a short while. To do this, I copy the files off the camera's micro SD card onto my notebook. The SD drive is mounted via a USB adapter into a USB port. The latest batch consists of 531 files, totaling 52Gig.

Always, after the copy reaches about 40 files / 4 Gig total, the SD drive goes offline and the last file copied is always unreadable. I've tried copying from the standard file manager, and from a shell using cp and get the same issue. I've also tried copying the files individually using a shell script, but this fails in the same way. To start the copy again, I need to take the SD card out and insert it again, and then I can continue.

Thinking this might be a Linux constraint, I tried the same thing on a Windows 10 machine, and this failed in much the same way, although it did copy a few more files before the failure.

The SD card seems fine, and I can eventually copy all the files after multiple copies.

Does anyone have any idea what the issue could be and if there is a way around it?

Update - I've moved all the files from my computer onto a Samsung Portable SSD T7 device, then tried to copy them back again using the standard Ubuntu file manager, and this worked just fine, so I guess the issue must be related to using an SD card, but I can't understand what it can be.

I did a clean installation of Ubuntu, removing the former Windows 10 OS. However, the laptop is stuck in a loop at booting. Via Esc > F9 I can start up from the EFI files. I checked GRUB and removed the former BOOT folder, but still "OS Boot Manager" keeps being the first option. No possibilities to put "Boot from EFI file" or "Ubuntu" as first option. Any suggestions? I want to get rid of the F9-detour.

I started to test Geforce Now Linux native app and in the game what I play I have an important keybinding on Alt+0 unfortunately I cannot use it, because this is also the shortcut for changing windows. Also unfortunately Alt+0 shortcut does not appear in the Keyboard/View and Customize shortcuts option.

Is there any way to delete or change this shortcut?

In Brave, with more than one tab in a window, I cannot select a tab without the selection moving to that to the left and eventually moving to the leftmost tab. Similarly in Ubuntu 24.04 when using "Show Apps," it always returns to the first screen of apps after clicking on the right-pointing arrow.

How do I correct both of these these?

how to check in the bash file dialog existence of the file "File Name", and if not. to open a new file "File Name" (in the w-r mode)?

I was trying to use my NPU on ubuntu, but messed something up and now running sudo modprobe amdgpu crashes my system. That is, the following happens: screen turns black -> login screen -> after login, black screen until reboot.

This issue arose after running the amdgpu-install command from this post: Enabling Ryzen-Ai workloads in Ubuntu Servers

which caused a build error related to amdgpu-dkms:

Error! Bad return status for module build on kernel: 6.17.0-14-generic (x86_64)
Consult /var/lib/dkms/amdgpu/6.10.5-2119913.24.04/build/make.log for more information.
    dpkg: error processing package amdgpu-dkms (--configure):
installed amdgpu-dkms package post-installation script subprocess returned error exit status 10
    Errors were encountered while processing:
 amdgpu-dkms
E: Sub-process /usr/bin/dpkg returned an error code (1)

I suspect that this has to do with amdgpu not being compatible with the kernel version that I have, Which is similar to this github issue: https://github.com/ROCm/ROCm/issues/4619 I am on ubuntu 24.04, kernel version 6.17.0-14-generic. And my cpu/gpu/npu is AMD Ryzen 7 8845HS with Radeon 780M Graphics.

How can I restore amdgpu to a working state? And what did I do wrong that broke this?

Any help would be greatly appreciated.

I have recently started using Ubuntu regularly and wanted a way to monitor my CPU temps.

I did the steps online of installing lm-sensors and doing sensors-detect.

This is the output for sensors-detect ->

# sensors-detect version 3.6.0
# System: Dell Inc. Dell G15 5515 [1.5.0] (laptop)
# Processor: AMD Ryzen 5 5600H with Radeon Graphics (25/80/0)

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): 
/dev/port: Operation not permitted

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): 
/dev/port: Operation not permitted

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.

This is relatively common on laptops, where thermal management is

Ubuntu 20.10: wine-6.2 with WOW64 and 32 or 64 bit program installations

When creating a 64 bit wine prefix it creates a directory structure with "Program Files (c86)".

I can launch 32-bit programs into it, but I always get prompts that tell's me it could go wrong because I use a 64-bit prefix. Although there is no apparent error.

At top of that, when I install a 32-bit program into this prefix, should I do it with wine, or wine64? If I do it with wine, will it use the "Program Files (x86)" or the default "Program Files" reserved for 64-bit programs on a 64-bit architecture?

It's not clear at all how to use a 64-bit architecture, with 32-bit applications/installations. The point is, some of the programs I want to install, have a 64-bit installer, but uses 32-bit launchers and are normaly installed into "Program Files (x86)".

My goal is to run a signel Prefix for all the apps I need wone for. This would mostly be used for game purposes.

How do I launch a prefix desktop WOW64, compatible for 32-bit and 64-bit apps as well?

What is the best way to install all I need into this only prefix, without this prompt about 64-bit prefix?

I have no choice to use other than a 64-bit. My prefix should be at HOME/user/wine64/

28/02/21

I've found out that I have to work with wine64 to run an exe within the x64 Prefix I've created. Even is this one is 32-bit Like the Steam setup for exemple.

'WINEARCH=win64 WINEPREFIX=/$HOME/.local/share/wineprefixes/Win64DXVK wine64 explorer'

I'm a newbie, but for me it's like winetricks runs some commands with wine instead of wine64, just because those are 32-bit applications. So my question at this points, if it's so, there a winetricks version that runs everything with wine64 instead of wine?

I'm looking how to work directly trough wine64, because winetricks give me these error prompts about WINEARCH 64.

WINEARCH=win64 WINEPREFIX=/$HOME/.local/share/wineprefixes/Win64 winetricks

When I'm working directly with the prefix, I've getting things to work somehow. But it would be easier for me if I could also use winetricks in full WOW64 environment.

I want to know if it's possible, by modifying some configuration files, to change the vertical position of Plank dock. Unfortunately in the settings you can only decide whether to put it at the top, bottom, left or right while I would like to keep it at the bottom but slightly higher than where it is put by default.

Screenshot

As you can see from the screen, the lower edge of the dock is too attached to the lower edge of the screen, I would like to move it slightly higher.

I had Ubuntu 19.04 64-bit virtual machine. I upgraded it to 19.10. After the upgrade finished, the virtual machine got stuck on boot in VMware Workstation 15. I had used a vmdk image for 19.04 available here: www.osboxes.org/Ubuntu

While I was upgrading the virtual machine I followed the instructions here.

What could be the problem here? Why is a fresh upgrade not able to boot? What should I check in here or do to fix this?

This is a fresh upgrade and whatever kept happening I let it happen. I logged in to tty6 and I got the following screen.

I have not restarted the system since the upgrade from 19.04 to 19.10 kept happening.

Then while I posted this question here I some how was able to restart the system and now I get:

end kernel panic not syncing :VFS: Unable to mount root fs on unknown block (0,0)

Now I don't know what should I do. Why this problem came. How to debug this and fix this. Rather than creating a new VM by downloading a new ISO I am more interested to learn and fix the problem which has caused this.

I seem to have figured out something which might be applicable as mentioned at Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0). The thing is before upgrading I did not note down on a paper and pencil which kernel version was running or to what version the upgrade took place. I have been running defaults only, so it should not be a problem.

Someone in comments mentioned:

"On my Ubuntu 19.10 I've had to run apt install initramfs-tools in order to get update-initramfs command –"

I do not know how to work with the Advanced boot menu. Please see the screenshots I uploaded to understand my situation.

Advanced boot options:

Which kernel to boot in Advanced boot options:

Even after booting into one of the kernels in advanced options, I get kernel panic messages.

There is some knowledge gap in my situation. I probably have figured out something which I should try, but I am not able to understand how to proceed from here.

In the building where I am living is having a WiFi with two channels and same SSID. Whenever I connect to the WiFi, it always connects to the 2.4GHz band but I want to connect to 5GHz band. I have already tried this but all in vain. Also, I have tried linSSID app but it isn't even launching.

I've installed several Linux distributions and my touchpad isn't working in any of them. USB mouse works fine and the touchpad works on Windows 10. I tried many different things I found and none of them got good results. I'm using a Lenovo Ideapad 320 laptop running a Windows 10 and Ubuntu 17.04 dual boot.

I get it after updating in Synaptic Manager

I recently did a clean install of Ubuntu 17.04 from 16.10.

error message:-

W: Download is performed unsandboxed as root as file '/var/cache/apt/archives/partial/samba-libs_2%3a4.5.8+dfsg-0ubuntu0.17.04.1_i386.deb' couldn't be accessed by user '_apt'. - pkgAcquire::Run (13: Permission denied)

My netgear wireless adapter appears to be the same model as from this thread, but the steps didn't end up working out for me. No errors were given. Note: This is the second attempt, so some files are already installed/updated. I'm on a fresh install of Ubuntu 16.04, I'm not used to the environment.

Here's the terminal after each step:

1. Note: I can't post more than 2 links, so I delete the http:// in front of the hits/gets.

2. Downloaded the files from post #6 and put them onto my desktop.

   $ arch
   x86_64
   $ cd ~/Desktop/Broadcom_bcm43xx_USB_32_64bit_v2
   

   My command line now appears as:

   shawn@shawn-Z68XP-UD3P:~/Desktop/Broadcom_bcm43xx_USB_32_64bit_v2$ 
   

3. As arch returned x84_64 I issued:

   $ sudo ndiswrapper -i bcmn43xx64.inf
   driver bcmn43xx64 is already installed
   
   $ sudo ndiswrapper -ma
   module configuration information is stored in /etc/modprobe.d/ndiswrapper.conf
   

4. This step didn't return any information back.

   sudo depmod -a
   

5. This step also didn't return any information back.

   sudo modprobe ndiswrapper
   

Thanks for any help. I was going to pm Chili555, the author of the answer to the previous thread, but I couldn't find an option. (Maybe I need more rep?)

I justed upgraded to Ubuntu 16.04 LTS. Everything looks fine except the modem.

First, the modem connects but the icon doesn't change. It still shows 'disconnected icon'. Old computer shows right icon after connecting.

2nd, the connection shows 'EDGE' in bracket. On old computer connection shows 'HSPA'. This means browsing on the upgraded ubuntu in nearly impossible.

Lastly, on old computer when I unplug the modem I get the message "Network - disconnected you are now offline". On new version of ubuntu no message appears.

Not sure whether this is a problem with new hardware or with ubuntu. But it's definitely not a problem with the modem since same modem works perfectly on old computer.

Any idea?

Thanks.

I have used mount --bind to mirror my Windows desktop folder to Ubuntu. I have set it up to mount on boot but the desktop does not refresh the icons so I have to logout and log back in to make the icons appear.

Thanks in advance.

Update:

I am running 12.10 if that changes anything.

Also I have tried killall nautilus.

When you rename files with a different extension, most of the time it does not work. But, if you have a .png file, you can just rename image.png to image.jpeg or image.gif, and it automatically gets converted to the other format and works perfectly fine. Is there some similarity between these formats which allows this to be done? I noticed this a few years back, and got interested when I was trying to convert a .dvi file to a .pdf file; just renaming it worked!

It has been suggested to me that the use of a chroot might solve my problem of building an application that must run on an embedded device. I have inferred from this description that it is somehow similar to creating the embedded environment locally on my machine which I can then use to develop on from my desktop development machine. Is this the right way to look at the functionality or have I totally misunderstood?

In order to get some idea of how it works I read this https://wiki.ubuntu.com/DebootstrapChroot which I will attempt to make a chroot for an old Ubuntu version on my machine. However, as I am a total linux novice, I am a bit concerned that as I do not entirely know what I am doing is there anyway that I could end up with an unusable system?? Is this something that a novice should even attempt???

How do I update a single package? As far as man apt-get says apt-get upgrade doesn't take a package/list of packages as parameter:

upgrade

upgrade is used to install the newest versions of all packages currently installed on the system from the sources enumerated in /etc/apt/sources.list. Packages currently installed with new versions available are retrieved and upgraded; under no circumstances are currently installed packages removed, or packages not already installed retrieved and installed. New versions of currently installed packages that cannot be upgraded without changing the install status of another package will be left at their current version. An update must be performed first so that apt-get knows that new versions of packages are available.
