I am having trouble with my laptop shutting down at 92% charged. I bought a new battery and everything worked fine. Then I did an update and now it shuts down. It is very frustrating. I have a laptop that should be portable but has to be plugged in all the time.

Running and Asus Q504UA with Kubuntu 24.04.

I ran the acpi command and this is the results:
Battery 0: Not charging, 98%
Battery 1: Discharging, 0%, rate information unavailable

I am not sure what this means. I hope that someone as the info to help. I am starting a new job and need to be able to use the laptop with out being plugged in.

I need to open a .ppsx file in Ubuntu 24.04, so I suppose I need Impress to do that?

I have LibreOffice Calc, Writer & Draw, but not Impress. When I try to install Impress via the Ubuntu App Center, the "Install" button has no effect & I am left with a very long & daunting article about handling Deb packages...

Is it really so complicated to install Impress?

Thanks for any guidance!

I'm trying to edit some GRUB configuration. All of the guides for this, including the official documentation, refer to a configuration file /etc/default/grub. On the Ubuntu 24.04.03 ISO I'm working with, there is no such file. There is a drop-in directory /etc/default/grub.d/. There is no guidance anywhere on the internet from the people who created this about how to work with it, despite the fact that it appears to have been a source of confusion since at least 2019.

Are there any rules for filenames placed in this directory?

Most of the guides I've found (again, including the official GRUB documentation) indicate I should run update-grub after making changes to configuration. This is not present on the Ubuntu 24.04.03 ISO I have:

root@cubic:~# which update-grub
root@cubic:~#

I had to find a random blog post to suggest that update-grub is an alias for grub-mkconfig -o /boot/grub/grub.cfg, which is available on the ISO. Is this accurate? If I add files to /etc/default/grub.d/ and then run grub-mkconfig -o /boot/grub/grub.cfg, is this the exact same as running update-grub?

I use a GUI tool Lxqt-config-input -> Mouse and Touchpad -> Scrolling: Edge.

How to force these settings permanently? I'm on Lubuntu 22.04.

I'm running Ubuntu 24.04 with 6.8.0-85-generic kernel on Wayland (with gjs (the standard GNOME JavaScript environment)) and have the power setting for the power button set to hibernate.

When I select hibernate from the power off menu, and restore from it, it restores to lock screen (normal for resuming from standby and restoring from hibernation). My USB WiFi restores back to the router where it was before hibernating.

When I use the power button to hibernate, and restore from it, it restores to the login screen. That also resets my USB WiFi from the router (where it was before hibernating) to the extender. FYI - both of these also happen with newer kernels when restoring from hibernation, even when using the power off menu

btw - Restore is normal using power off hibernate with 6.8.0-85/84/79/53...

I know this is a common question, but I've tried everything I can find and can't make it work. Normally I can figure this stuff out, but I'm stumped.

Ubuntu 24.04.3 LTS, guest on VMWare Fusion on MacOS Tahoe. Shares are from a UNAS Pro.

I've followed lots of guides (as none work so far), but lets use this one which seems to be "official":

How to mount CIFS shares permanently

What is really weird to me is that the fstab etc. entries must be "right enough", as double clicking the folder mounts the drive, so does sudo mount /mnt/movies, but after rebooting I get a permissions error. I messed with some settings again last night, and now the behaviour is a reboot gives no messages, but using the Files app and navigating to the movies folder shows it as empty (no errors in the GUI). Opening terminal and issuing sudo mount -a asks for a password and returns no errors. Then the Files app shows content in the two mapped folders.

Relevant tstab entry is:

//nas.lan/Movies /mnt/movies cifs credentials=/home/plex-admin/.smbcredentials 0 0

Any help hugely appreciated. And Happy New Year!

The problem I faced is something similar to this while live booting into my old hp laptop. I've tried other solutions like removing quiet splash but all it does is showing status of successful or fail processes. How to solve this?

The laptop spec:

CPU: Intel(R) Core(TM) i7-6500U CPU @ 2.50 GHz
Memory: 12 GB of DDR4 RAM
GPU 1: Intel(R) HD Graphics 520
GPU 2: NVIDIA Geforce 940MX

I've attached the log fie, hope this might be useful.

Thanks

Update: I've tried to start using "safe graphic" option but it will still show the same error message. But after that, it will boot to a black screen and freeze with a cross cursor.

Can I get some assistance with getting my MacBook Pro internal speakers working? Sound plays fine through my Bluetooth headphones.

System details:

Pulse audio on Pipewire:

Noticed that a USB lead to my external drive was unconnected lately.

The external HDD was used to store Timeshift backups of my 24.04LTS system. So I immediately reconnected and tried to get an immediate snapshot made. Although it went through the motions (desktops icon arrow, flashing lights on the HDD, etc) no actual new snapshot was created.

I tried it over and over. I changed to an external SSD. All to no avail.

Lately I ran it via the CLI:

~$ sudo timeshift --create

Does anyone have any idea as to what may be wrong ?

Whatever it is, it seems to be more to do with Timeshift rather than the drive device, as it's failing on both HDD and SSD drives.

I have a spare, encrypted, internal HDD that I use for backups. I use cryptsetup and x-systemd.automount to automatically mount the drive on startup. I also set x-systemd.idle-timeout=15min to put the drive to sleep, since it's only active for a few minutes per day. This setup worked as intended for over a year, but recently I noticed that the drive stays mounted and spinning 24/7.

Current config:

# /etc/fstab:
/dev/mapper/hd_crypt    /mnt/hd_plain ext4    nofail,x-systemd.device-timeout=30,x-systemd.automount,x-systemd.idle-timeout=15min

# /etc/crypttab:
hd_crypt UUID=<device-uuid> /etc/path/to/encryption.key luks

Symptoms:

• The backup runs via user crontab every night at 2am and finishes in a few minutes (as I can confirm in my borg backup logs)
• In the morning, I hear the drive spinning, and dmsetup info hd_crypt shows that the LUKS device is still active even well after the backups are complete
• lsof and fuser confirm there are no processes still accessing the mount
• journalctl shows the mount unit be activated at startup and deactivated at shutdown, but no records coinciding with the 2am backup time or anything about idle timeout

My understanding gleaned from these symptoms is that the idle timeout unmounts the decrypted ext4 filesystem, but the underlying LUKS device (/dev/mapper/hd_crypt) remains open, which keeps the drive awake.

My question: Is there a systemd-native way automatically close the LUKS device (not just the mount) when the filesystem undergoes idle timeout?

Constraints (in priority order):

1. I don't want to run my borg backups as sudo (which rules out wrapping it in sudo cryptsetup commands)
2. I don't want to switch to autofs
3. I want to avoid writing a custom systemd service if possible (but if this is the only way, then my question is how to do so and make it integrate with borg backup reliably)

Ubuntu 25.10.

I recently added a SATA SSD to my MSI 620M-B Pro (latest BIOS) motherboard and configured it to mount automatically via /etc/fstab.

While the drive mounts and works perfectly during the session, I encounter a brief error message (lasting about 0.5s) on a black screen every time I reboot or power off the system:

unmount error /mnt/ExternalSata

Because it disappears so quickly, I cannot provide a screenshot, but the message clearly points to a failure in unmounting that specific path.

My /etc/fstab configuration for this drive:

Bash

UUID=77938595-6a70-4e9c-aa0e-4b081d6afcb5 /mnt/ExternalSata auto nosuid,nodev,nofail,x-gvfs-show,x-systemd.device-timeout=60s 0 0

System Details:

• OS: Ubuntu (latest updates installed)

• Motherboard: MSI 620M-B Pro

• Mount Point: /mnt/ExternalSata

I suspect there might be a dependency issue with systemd or an incorrect mount option causing the drive to stay "busy" during the shutdown sequence.

Has anyone encountered this specific unmount error, or is there a recommended mount option I should add (like _netdev or lazytime) to ensure a clean unmount?

Thanks in advance!

I want to istall ubuntu on my new laptop a honor magic book 14 pro with a ultra 5 125h processor.

Details:

-- Core Issue:

The Ubuntu installer fails to find the bootable medium (USB stick) after starting the boot process.

Error Message: "unable to find medium containing a live file system"

-- Initial Troubleshooting Steps:

BIOS Configuration: Secure Boot and Fast Boot have been disabled.

BIOS Limitations: The system BIOS is locked down and does not provide any settings to change the storage controller mode (e.g., no option to switch from Intel VMD/RST to AHCI).

Hardware Verification: The same bootable USB stick and ISO image were successfully used to boot another laptop, confirming the integrity of the installation medium. Different USB ports were also tested on the Honor laptop.

Firmware: Checked the official Honor support website; no BIOS updates are available for this model.

-- Tested Linux Distributions and Methods:

Ubuntu 24.04 LTS: Fails with the core error.

Ubuntu 25.04 (Daily Build): Fails with the exact same error, suggesting the issue is not resolved by a newer kernel (as of the date of testing).

USB Creation Method: The live USB was created using Rufus in both "ISO Image mode" and "DD Image mode," with neither method resolving the issue.

-- Tested Kernel Boot Parameters and Results: A series of kernel parameters were tested by editing the GRUB command line at boot.

nomodeset: No effect, still resulted in the "unable to find medium" error.

nvme_core.default_ps_max_latency_us=0: No effect, still resulted in the "unable to find medium" error.

intel_iommu=off: This changed the behavior. The system froze indefinitely at the graphical Ubuntu loading screen (with the logo spinner).

acpi=off: This also changed the behavior. The system froze at an early text-based stage, displaying only the message "booting a command list".

is there any way to fix this or do I just have to wait until this is adressed by honor or linux developers ?

Did I miss anything that might solve this problem ?

I've installed KerioControl VPN client on UBUNTU 22.04 and configured it with no problem, but it restarts the connection when I stop it using sudo /etc/init.d/kerio-kvc stop.

I think it's because of <connection type="persistent"> in config file.

With this type I should disable the connection by changing <active>1</active> to <active>0</active> and reload the config file every time, but there should be a better way.

In windows client there is a checkbox to enable/disable persistent connection, but in linux there is no GUI and it's configured using CLI.

Is there any other type of connection or a better way to prevent reconnecting?

I can't adjust the brightness in Ubuntu 24.10. Adjusting via the brightness slider or using the Fn+F3 or F4 keys doesn't work.

IDM is installed on Ubuntu 22.04. I cannot fix Mozilla Firefox as browser, nor use the "Advanced browser integration". My Firefox problem is that in IMD I have to choose a browser. No browser is accepted as such. I receive the remark: I have to use the "Advanced Browser Integration". Trying it I receive the remark that the "Base Filtering Engine" is missing.

I'm trying to add the flatpak repository with this command: sudo flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

But I'm getting this error:

How can I fix this? (Tried reinstalling flatpak and ca-certificates but it doesn't seem to work)

It used to work until yesterday at least, and I think it happened after installing and running a virtual machine through Virtualbox. Pretty much the whole desktop is idle and unusable. I don't mind this, as I don't usually use the desktop to store files or folders on it, but I am curious what I did and how it can be reversed or intentionally brought to this state.

At some point icons disappeared, can't be added, I can't left click + hold to select anything, and the right click menu doesn't give me anything but the 3 options seen on the screenshot. The right click menu works fine when I am in folders though.

VirtualBox 6.0 is installed with the corresponding Extension Pack.

I need to add a custom debian package from artifactory to my server.

The issue is that I manage to upload the package and sign it but when it comes to do sudo apt-get update I get

W: GPG error: https://mycompany.jfrog.io/mycompany/deb-release-local bionic Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 782E27A43CDD3263

Now, the gpg keys (pub and priv) have been added to artifactory although I have not found a way to add it to my local apt. I have tried:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 782E27A43CDD3263

but without luck. I have tried to change the keyserver to point to my artifactory endpoint but it times out.

I'm getting a 35 second delay during boot which I am unable to understand the reason about.

My PC is running Ubuntu 17.10 Kylin, and Windows 10 dual boot.

After I select ubuntu in grub2, the screen goes black for around 40 seconds. After that it boots without any problem.

I am investigating the reason behind 40 second time lag (black screen).

I am pasting here the dmesg log partially, other part I found ok less than 10 second time.

Please let me know what may be the reason which leads to a delay 9 second to 44 second in below attached log ??

I have compressed couple of files and folders (mostly photos) using 'Archive Manager' on Ubuntu 14.04. During compression I've selected file type as AR from the drop-down selector.

Now when I'm trying to decompress that *.AR file using 'Archive Manager', it decompresses only the files were on the root folder. But, the AR file size is showing the exact as it was during the compression.

Could anyone please help me to decompress the AR file properly?

Thanks.

I have installed PowerBroker aka Likewise-open on my Ubuntu 14.04 desktop. I successfully added the desktop to the domain but I am unable to login as a domain user at login screen. I found some answers on other posts saying to edit the 'lightdm' file but 14.04 has no such file.

Any help would be appreciated.

I installed open office 3.4 in my system Ubuntu 12.04 by following steps

1. download Apache_OpenOffice_incubating_3.4.0_Linux_x86-64_install-deb_en-US tar file
2. and extract the file manually and cd en-US
3. cd DEBS
4. sudo dpkg -i *.deb & cd desktop-integration again use same command sudo dpkg -i *.deb

Here how can I set openoffice as my default program

When for whatever reason my home partitions gets mounted read-only, sudo fails:

/usr/bin/sudo: Input/output error

From what I understand, it seems to be trying to touch ~/.sudo_as_admin_successful

Is there a way around this, to use sudo to remount my harddisk? Should I file a bug?

As FFmpeg is going to be dropped from Ubuntu, it will be important to know how to broadcast videos over Intrnet using avconv. An official guide is available, but it doesn't give much information how to work it out, step by step...
I have tried several times, but no luck.
Your simple & complete instructions are highly appreciated....!

Thanks!
