I can not get Streamtuner2 to work properly on 24.04. I can get to internet-radio top menu but when I try to step down it will not step down into the categories. (the catalog of stations is the desirable part of the program) When I select Online Forum under help, it opens VLC and nothing opens in VLC. In Shoutcast, I can step down into the menus and select a station that will play. I have purged and reloaded by several methods and this best result was achieved with the terminal - sudo apt install streamtuner2

Searching online, it appears that Streamtuner2 may be obsolete. Is there another program that will do the same thing, including the station lists to pull from?

Laptop Model: Dell Pro 14 Premium (PA14250)

CPU/GPU: Intel Core Ultra 200V (Lunar Lake), Graphics ID 64a0 (Stepping B0)

OS: Ubuntu 25.10 (Kernel 6.17.0-14-generic) same with Ubuntu 24.04

Firmware: Dell BIOS 2.4.2 same with Dell BIOS 2.9

The Issue: The system boots, decrypts the LUKS partition, and completes the services load (reaches snapd.apparmor.service), but then stops there. Does not reach the login page. I tried a couple of GRUB workarounds. The system is active in the background (keyboard lights up on trackpad touch), but Ctrl+Alt+F3 does not bring up a TTY. LLM suggests that: the xe driver is hanging during the display initialization handshake. Key Logs (via journalctl -b -1):

xe 0000:00:02.0: [drm] Found lunarlake (device ID 64a0) integrated display version 20.00 stepping B0

xe 0000:00:02.0: [drm] Selective fetch area calculation failed in pipe A

gnome-shell[3032]: Added device '/dev/dri/card1' (xe) using atomic mode setting.

wmi_bus wmi_bus-PNP0C14:02: [Firmware Bug]: WQBC data block query control method not found

What I have tried so far:

BIOS Updates: Updated to 2.9

GRUB Parameters: Tried combinations of xe.force_probe=64a0, xe.enable_psr=0, xe.enable_fbc=0, and video=eDP-1:e.

Blacklisting: Blacklisted intel_vsc and intel_ish_ipc to resolve a -517 context sensing error.

Display Server: Disabled Wayland in /etc/gdm3/custom.conf to force X11.

Firmware: Verified lnl_guc_70.bin and lnl_huc.bin are loading successfully.

Workaround: System only boots with nomodeset, but this disables all graphics acceleration.

I have a user named appadmin1 who does not have full sudo access.

I want to allow this user to run only: sudo apt update sudo apt install

But the user should NOT have access to any other path except opt/app i want to run these commands only these path

I created a sudoers file using:

visudo -f /etc/sudoers.d/appadmin1

And added the following line:

appadmin1 ALL=(root) NOPASSWD: /usr/bin/apt update, /usr/bin/apt install *

I installed TLP on a ThinkPad T440 with Ubuntu 24.04 by running . After going through a typical installation process it appears to be installed. But I can't find it. Wherever I look, it's not there. Was I supposed to do something else after installing it?

in ubuntu 24.04 , emmc related modules is default available in initramsfs

user@localhost:~$ sudo lsinitramfs /boot/initrd.img-6.17.0-14-generic | grep -Ei '(mmc_block|mmc_core|cqhci|sdhci).*.ko'

usr/lib/modules/6.17.0-14-generic/kernel/drivers/mmc/host/sdhci_f_sdh30.ko.zst

Observe that ubuntu26.04 snapshot3 missing emmc modules in initramfs

user@localhost:~$ sudo lsinitramfs /boot/initrd.img-6.18.0-9-generic | grep -Ei '(mmc_block|mmc_core|cqhci|sdhci).*.ko'

user@localhost:~$ echo $?

1

This unfortunately lead to disk image of ubuntu26.04 failed to boot in emmc.

Anyone know the reason of emmc related modules do not include in ubuntu 26.04 initramfs?
Remark: ubuntu 26.04 snapshot3 bootable when update ubuntu26. 04 initramfs to include emmc modules using dracut.

I ran my ACER laptop with Windows alongside my Ubuntu (one harddrive) perfectly until Windows forced an update. Now Ubuntu isnt able to boot and falling back to BusyBox shell as follows: " Gave up waiting for root file system device. Common problems:

• Boot args (cat /proc/cmdline)
• Check rootdelay= (..)
• Missing modules (cat /proc/modules; ls /dev) ALERT! UUID=XX does not exist. Dropping to a shell! "

I assume this is a rather quick fix for advanced users but to hard for me :/ Help is much much appreciated since I need to access my data rather urgently.

Many thanks in advance.

Edit: Both Win and Ubuntu run in UEFI mode. I deactivated Hybernate / Fast boot in Windows. Still falling to shell while booting Ubuntu. Running boot-repair from live session just brings the following report:

Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would not act on the boot.

We need to run the FAST-LIO (LiDAR SLAM) algorithm, which we have already tested successfully on Ubuntu 20.04.

Previously, we were using a system with:

• Ryzen 5 CPU

• 32 GB RAM

• No dedicated GPU

However, during LiDAR map generation, the system gets stuck and performance is very poor.

To solve this, we upgraded our hardware to:

• Intel i9-285 processor

• NVIDIA RTX Ada 2000 GPU (16 GB)

• Higher overall system performance

Now we are facing a new problem:
How do we properly install Ubuntu 20.04 on this Intel i9-285 system?

Questions:

1. Does Ubuntu 20.04 fully support Intel i9-285 CPUs?

2. Are there any special BIOS settings, kernel versions, or drivers required?

3. Should we install Ubuntu 20.04 directly, or use Docker/VM as a workaround?

4. Has anyone successfully run FAST-LIO or similar LiDAR SLAM pipelines on this hardware with Ubuntu 20.04?

I just installed 25.10 and selected not to require a password to log in. Every few minutes, if I do not hit a key or click the mouse, I get locked out and must re-enter my password.

How do I get rid of this?

Using tmux in a script, tmux produces messages like [remote detached from 585664.devpts0] or [exited]

How can these messages be suppressed?

I use in config

set -g visual-bell off
set -g status off; 
set -g visual-activity  off

and 2>/dev/null for all the tmux commands, but I can't get rid of the messages.

I'm a new user and wanted to try Linux. I downloaded the Ubuntu 24.04 ISO, installed it on a USB, and booted into it. I selected "install/try" and it loads the desktop. Attached is what I see. The install window is distorted and I can't click anything on it. I've restarted several times and it persists. The app icons in the app bar on the left (when expanded) look fine.

In the recent upgrade, the following packages changed:

Start-Date: 2026-02-28  19:10:05
Commandline: aptdaemon role='role-commit-packages' sender=':1.3465'
Upgrade: google-chrome-stable:amd64 (145.0.7632.109-1, 145.0.7632.116-1), software-properties-common:amd64 (0.99.49.3, 0.99.49.4), python3-software-properties:amd64 (0.99.49.3, 0.99.49.4), software-properties-gtk:amd64 (0.99.49.3, 0.99.49.4), linux-firmware:amd64 (20240318.git3b128b60-0ubuntu2.23, 20240318.git3b128b60-0ubuntu2.25), brave-browser:amd64 (1.87.190, 1.87.191)
End-Date: 2026-02-28  19:10:25 

Today, I discovered that my this upgrade caused my system 32GB of RAM to show up as 4GB of RAM. I suspect that linux-firmware:amd64 (20240318.git3b128b60-0ubuntu2.23, 20240318.git3b128b60-0ubuntu2.25) caused this issue.

How do I undo this problem?

I want to install the Canon imageRUNNER 2425 driver in my system. I tried other options from YouTube and Ubuntu, but I could not get the printer driver installed successfully.

What it says is:

dpkg: dependency problems prevent configuration of cnrdrvcups-ufr2-uk:

Now what to do?

I just booted and I'm getting this fuzzy and unreadable window. I'm not sure what to do.

I'm experiencing an issue with my Lenovo Ideapad Slim3 with a AMD CPU and graphics running the latest version of Ubuntu. When I close the laptop lid and it remains in suspend mode for an extended period, the internal laptop keyboard stops working upon waking up. The touchpad and any externally connected keyboards continue to function normally.

I'm using gnome classic on Ubuntu 24.04, and I would like to add some launcher icons on the top bar, but I can't find how. In previous versions of Ubuntu/Linux/Gnome, I would either right-click where I wanted the icon and a menu would pop up with the option "add app launcher", or I would find the app in the menu and drag the icon where I want it on the bar, but none of the options is available in my version.

I don't know what version of gnome classic I'm using, I did echo "$XDG_CURRENT_DESKTOP", and "echo $DESKTOP_SESSION", and all it says is it's gnome-classic, which I already knew, but no version number is given. If the exact version number is needed, let me know how to retrieve it.

Here is where I want the icons.

I'm relatively new to Ubuntu. I am single-booting it on a relatively new Lenovo laptop (factory installed with Ubuntu) and am stuck at the GRUB command line (GRUB 2.04). When I try to ls, I get:

And when I try to ls further into these, everything seems to be an unknown file system. I have a liveUSB (though when I run from it I get these errors.

Do you have any tips on what I should do? I've got some files that I would love to keep if possible.

Setup:

• Ubuntu 22.04, clean install.
• Dell G15 5521 Laptop
• Latest firmware
• 6.0.8-060008-generic
• Nvidia 525.60.11
• X11 Ubuntu flavour of Gnome

Very randomly and very infrequently (probably once a day for me) a key appears to get stuck and auto-repeats. Pressing any other key stops the auto repeat.

This happens with the default kernel and with 6.0.8.

The problem does not occur on Windows 11. The problem does not occur when running the pre-post keyboard tests (fn key held down when powering on).

The problem occurs on multiple G15 laptops. I have one for work, one for personal use and work has 3 more. All exhibit the same random infrequent problem, but frequently enough to be complained at...

The problem does not always occur when the system is under load. Typing speed does not appear to have any influence on the issue.

dmesg does not show any thing related to keyboard or USB when the issue occurs.

I do not want to turn off key repeat (xset -r).

A bit more information on input devices:

Is there anything I can try to narrow down where this problem is occurring?

I have looked at numerous different posts and questions but the advice is limited.

Edit 20 September 2023

We now have 8 of the Dell G15's, all up to date. All have the same issue.

The problem does not occur when running Windows.

I am using the xrdp Tool to remotely access Linux Ubuntu and want to limit the users that are in the same network and can remotely log in to the PC if they know the username and password. This can be handled using xrdp.ini configuration file ? Or should I do something else. That is, I can identify which users in this network that can log in e.g. using their MAC Address or IP.

As the title stated, I enabled ubuntu gnome default screen share service. The good thing is it supports both MS RDP and VNC protocols. However I find the VNC only accepts one connection. If one user is already VNCed to the desktop, 2nd user (using realVNC) will only get an error "The connection closed unexpectedly". Another good thing is the RDP connection does not have this restriction. Several users can RDPed to the same desktop simultaneously(which is also wired since the real MS windows DESKTOP edition only accepts one connection). In /var/log/syslog there's an log event "gnome-remote-de[process id]: Refusing new VNC connection: already an active session"

Anybody knows how to make multiple VNC connections? Surely I can use RDP, but I'd stick with VNC since other computers works fine with VNC. Using more than one tool seems...annoying. Installing another VNC server seems an overkill.

amend: I just noticed the desktop is X11 not wayland. Delete all "wayland" above.

My laptop has an SSD and 16GB of RAM, so I know the problem isn’t specs. This laptop used to have Windows and I never ever had any performance issues with it, but this changed ever since I switched to Ubuntu. I did it because I work with Docker and it runs faster on Linux.

The problem is, sometimes the system just completely freezes and I have to wait several minutes for it to work again. There are times it takes so long it’s faster to reboot it with the power button. Does anyone has any idea of what may be causing this? It happens at least 3 times a day and I am pissed.

I usually use Docker, Firefox, Discord and VSCode at the same time. I used all this on Windows too, and never had any problems except for the fact that Docker works much better on Linux.

I am trying to use sftp to pull a file from a remote server.

Both client and server-side users are created with adduser --system and their shell is /usr/sbin/nologin. The users are called legit-backup.

Public-key authorisation has been configured for the client user to have SSH access to the server as a user of the same name. When I try to pull down the file /home/legit-backup/test a file using the command sudo -u legit-backup scp legit-backup@<remote-server>:~/test, I receive the error protocol error: mtime.sec not present, no files copy down.

If I change the remote user's shell to /bin/bash then sftp works as normal.

I wan to use /usr/sbin/nologin for security reasons, the user should not be able to have SSH access other than sftp, is it possible?

I want to use GStreamer on ubuntu 21.04. Here is what I have attempted:

user@host:~$ gst-launch-1.0 -v playbin uri=file:///home/user/thisVideo.mp4
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
/GstPlayBin:playbin0/GstURIDecodeBin:uridecodebin0: ring-buffer-max-size = 0

ERROR: pipeline doesn't want to preroll.

I think what this output implies is that the Quicktime demuxer is not installed on my system. Can somebody please tell me what I must do in order to play this video in GStreamer?

EDIT: It occurs to me that the problem is much deeper than just a missing decoder. Instead, it seems that I am missing all decoders. I have tried to apply GStreamer to various files of diverse formats, but I consistently receive messages of to the effect of 'missing decoder'. Here is yet another example:

user@host:~$ gst-play-1.0 /home/user/someAudio.flac
Press 'k' to see a list of keyboard shortcuts.
Now playing /home/user/someAudio.flac
WARNING No decoder available for type 'audio/x-flac'.
WARNING debug information: gsturidecodebin.c(921): unknown_type_cb (): /GstPlayBin:playbin/GstURIDecodeBin:uridecodebin0

no suitable plugins found:
Missing decoder: Free Lossless Audio Codec (FLAC) (audio/x-flac)

Reached end of play list.

So I think the problem will be solved when I make all common decoders available to my system. But how to do it?

After installing and restarting my computer from the Ubuntu Software Updater prompt, my computer never completes a boot due to Failed to start Daemon for power management error:

/dev/sda2: recovering journal
/dev/sda2: clean, 789912/30498816 files, 66894142/121965056 blocks
^[[20~^[[20~^[[20~^[[20~^[[20~^[[20~^[[20~^[[20~[FAILED] Failed to start Daemon for power management.
See 'systemctl status upower.service' for details.

I tried to go into the GRUB and boot an older Linux version there, but the same issue occurred.

Being unable to boot my system, I went into Recovery Menu to attempt to solve issue from there. When I attempted to use dpkg Repair broken packages, I hit another issue that I did not find talked about in the web:

Reading cache
Can not upgrade
An upgrade from 'bionic' to 'focal' is not supported with this tool."

As I keep running into issues popping up, I am not really sure what Ubuntu's Software Update really did to my computer. I am really not sure where to go at this point to address the issues.

I'm lately having slow startup times (90sec vs 20sec in the past) since I upgraded from Ubuntu 18.04 to 20.04.

I'm on Ubuntu 20.04.1 LTS 64-bit. I'm working on a hybrid SSD (120GB) + HHD (500GB) system, Intel Core i3-6100U CPU @ 2.30GHz × 4 and 8GB of RAM DDR4. My partitions are: SSD: 249MB EFI (/boot/efi), 40GB FileSystem (/), 8GB Swap and 72 GB FileSystem (/home). The HDD is not mounted.

I've formatted my system and re-installed Ubuntu, but the booting time is pretty much the same. I also tried to Open /etc/fstab (as superuser), remove (or comment out) the line contains old swap partition, set up a new swap:

# /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>
# / was on /dev/sdc2 during installation
UUID=cf116583-5203-458c-855e-6f412a1ba35d /               ext4    errors=remount-ro 0       1
# /boot/efi was on /dev/sdc1 during installation
UUID=4C04-C9BD  /boot/efi       vfat    umask=0077      0       1
# /home was on /dev/sdc4 during installation
UUID=a5f9b844-bb2a-49e0-9a8e-d88c76eeb832 /home           ext4    defaults        0       2
# swap was on /dev/sdc3 during installation
# UUID=3bd915e8-cdd5-4ffd-a477-b355a73d53b3 none            swap    sw              0       0

And, I also cancelled the Press Ctrl+C to cancel all filesystem checks in progress message at the booting by adding fsck.mode=skip to /etc/default/grub.

Here are some commands I ran for troubleshooting along with their respective output:

$ systemd-analyze time

My computer keeps going to emergency mode. I tried Boot-Repair and checked and repaired file system.

If I reinstall Ubuntu MATE, will I lose all my customizations?

I'm using Ubuntu 20.04 LTS on a Dell Latitude E7250
After updating to latest Ubuntu software, when I rebooted a black screen with this boot message appeared.

Virtual console tty2 (For more information about how to interpret this screen see the answer to this question.):

I am using Ubuntu Budgie. It was working file until this morning. I don't usually shut down my laptop at all, but yesterday my battery drained completely, so after I charged it I tried booting it up. After start grub my Ubuntu logo appeared and later a black screen with some nerdy boot messages was visible and every time I boot it gets stuck at that process.

My mouse and keyboard work fine in Ubuntu, as well as grub. However, when I boot into Windows 7, I cannot get past the login screen because the mouse and keyboard do not work. The lack of light on my mouse indicates that it's not even on. This happened before when I tried to manually install Ubuntu (partitioning myself with gparted) so I reinstalled and let Ubuntu do everything for me ("Install alongside Windows 7" option) and I thought that fixed the problem because the mouse and keyboard worked twice in a row. Now, however, they have stopped working again. I am using a Logitech K120 keyboard and a Deathadder mouse. Both are plugged into usb 2.0 ports.

I just installed Ubuntu 11.10 32-bit version in dual boot mode on an ASUS K53. Every thing seems to work fine except for the wireless. The wireless works on Windows 7. Ubuntu finds the wireless card, but it does not appear to be turned on. The only physical means of turning on the card is the FN-F2 key combo. That works on Windows, but not in Ubuntu. I've looked in the forums for a solution and I'm not quite sure what to do. I've gathered the following information:

Any help would be appreciated. Thanks.

I just built a desktop computer using an ASRock E350M1 board, powered by an AMD Fusion E-350 APU (AMD Radeon HD 6310 GPU Model). I installed Ubuntu 10.04. Did all the updates. Almost everything works great: I can see movies (DVD), surf, etc., but I cannot play games --screen frames are very, very slow. I have not installed any hardware drivers. When I search (in Ubuntu) for the hardware drivers, none are found.

I found here, http://wiki.cchtml.com/index.php/Hardware that the graphics card is officially supported: PALM | Radeon HD 6250/6310

If this is of any help, this is what I entered on the terminal:

lspci -nn | grep VGA

00:01.0 VGA compatible controller [0300]: ATI Technologies Inc Device [1002:9802]

^C
sudo apt-get install build-essential cdbs fakeroot dh-make debhelper debconf libstdc++6 dkms libqtgui4 wget execstack libelfg0 dh-modaliases

I do not know what to do from here.

Questions:

• Where can I locate the drivers?
• How do I install the drivers?
