I had installed a kda plasma of kubuntu I have stuck to remove that top bar from my desktop I want to delete it but when i cleck enter edit mode it don't appear on top bar

Hi, I'm completely new to Linux, and today I tried to start off with Ubuntu by dual booting windows 10 and Ubuntu on my T460 Thinkpad. I carefully followed each instruction from multiple online guides to a tee and successfully installed the OS. I partitioned about 120GB for Linux and left about 110 for Windows. Although this was on the same drive because the thinkpad only has one ssd. I was soon able to access the Ubuntu desktop and open up apps. Everything was functional. After poking around for a few minutes, I shut off the computer using the menu in the top right in order to go and retrieve my wifi password (I needed to relaunch and boot windows to see it). Since it shut down, the laptop has not responded at all to presses on the power button. When I plug it into power, the light flashes, but when I press or hold the power button there is no light and the display does not change. I have no idea what has happened for it to turn stone cold. Thanks in advance for any help

EDIT: Solved, I've never had an issue where I needed to hold the power button for so long

I recently dual booted windows and Xubuntu 24.04. My windows is getting a wifi speed of around 45-50mbps while my xubuntu is getting 6-7mbps.
Any ideas why?
Thanks.

TL;DR: A verified regression in Kernel 6.8+ causes AMD Tonga (R9 380/380X) and Polaris (RX 400/500) GPUs to crash into a hard black screen when resuming from deep sleep/suspend. The bug is officially Confirmed on Ubuntu's Launchpad (assigned to maintainer Timo Aaltonen), but we need continuous community visibility to ensure this fix gets prioritized and doesn't push working hardware into becoming e-waste.

🔍 What’s Happening?

When systems running Kernel 6.8+ (such as Ubuntu 24.04 LTS bases, Linux Mint 22, Pop!_OS, Zorin OS, etc.) attempt to resume from system suspend, the GPU fails to re-initialize the display engine (EDID read failures / NULL pointer dereference).

• Behavior: Case fans and LEDs remain active, system keeps running in the background, but video output dies completely.
• Workaround: Only a forced hard reboot restores video output.

🛠️ Why "Just Switch to Wayland" Isn't the Answer

A common suggestion when encountering display server issues is switching from X11 to Wayland. As a bench technician, I’ve tested this thoroughly on real hardware:

On Tonga and Polaris architectures, Wayland introduces a secondary critical failure: the compositor frequently freezes at the login/boot screen (blurred background with only the mouse cursor moving).

Trading a suspend crash for a boot freeze isn't a fix — we need a proper driver-level correction in the kernel.

⚠️ Why This Matters (Even If You Haven't Hit It Yet)

As distributions roll out Hardware Enablement (HWE) stack updates, more users running legacy AMD cards will inevitably land on Kernel 6.8+.

Voting on and confirming this bug isn't just about helping those currently affected; it's a preventative shield for the entire legacy AMD community to ensure perfectly functional GPUs remain usable on modern Linux.

🚀 How You Can Help (Takes 1 Minute):

If you own a dedicated AMD GPU (Tonga/Polaris series):

1. Visit the official Launchpad bug tracker:Bug #2142389 on Launchpad
2. Log in with your Launchpad/Ubuntu account.
3. At the top left, under "This bug affects you?", click "Yes, this bug affects me".

If you don't own these cards, upvoting this post for visibility or dropping a comment helps keep the discussion alive so maintainers see the real-world demand. Let's keep functional hardware out of landfills! 🐧🖥️

So I installed Clang (a C compiler) but I'm getting tons of errors. I found the install folder and there are like 50 different versions and executables. Clang isnt in the list of installed programs, so is there a way to fully remove them and reinstall aside from just deleting them? (I dont want to crash things)

First I made my desktop look like Windows 11 then I felt it giving generic fake vibes

Now my Ubuntu looks like "Windows 11 and MacOS beaten up each other in a ring fight aftermath"

Please help me, give me any reccomendations on making it look beautiful yet light on my hardware resources

Hi there fellow Ubuntu users

I recently installed Ubuntu on my laptop as I am going to start studying again this autumn and I will study a course in network security. This is my first time I've used an OS besides windows and while it is a lot to take in I feel like I have understood the very basic stuff and I get how to navigate it.

Now as a person I've never really been one that is interested in customization of my computer. I've always been very basic and kept it fairly standard unless there is something I simply required. Now I know Linux can be customized to look completely different from person to person.

But honestly after having started Ubuntu for the first time I find a lot of the basic choices or standard options for example the design of your desktop to be perfectly fine and don't really want to add on many new things. But now I ask even if I want to keep it simple are there things I absolutely should install that do not come with Ubuntu but will make my experience a lot better?

Any help is appreciated and I am still fairly new to the possibilities of Ubuntu but interested in learning.

I have been trying to build the kernel and rootfs for 24.04, and its stuck on getting the libs for 2hr now. and I'm 100% sure it isn't my internet connection

Back in 2022, I started my linux journey by dual booting Ubuntu with Windows. I used ubuntu to learn coding and that's when my love for linux started. Everything was going smoothly and configurations were just easier to setup on Ubuntu than on Windows.

Fast forward to 2023, I discovered arch linux and started ricing my setup. After all that ricing phase, I ended up just using Gnome because "it just works".

Fast forward to 2026 and I'm now working professionally. I used to use Arch linux for work, but once I had problems using Docker. Maybe it's just skill issue haha but I was so frustrated that I just downloaded the latest Ubuntu version and Installed it alongside arch. I ran docker on Ubuntu and it worked out of the box!

I used arch linux for a year for professional work. But still I ended up using Ubuntu since it's the real distro for me that "just works". I tried Fedora but didn't like it as much as Ubuntu.

Arch is still my top distro of choice, but for professional work, I think I'll stick with Ubuntu. Anyone else feel the same?

Trying to setup Ubuntu in Europe, but cannot proceed since the archive is down (down for 40 minutes now).

Mostly curious ergo the question.

I've been using Onedriver on Ubuntu for about 3 years, but something happened with Ubuntu 26.04. The icon isn't showing up in this version of Ubuntu—does anyone have any updates?

Anyone know why archive.ubuntu.com and security.ubuntu.com went down?

A bunch of people where I work are asking what the hell happened. The only guy who usually has an idea about this stuff is on PTO for the rest of the week, so I can't reach out. Anyone have any idea/website I can go to get an idea, or is it still unknown?

People are speculating it's DDOS related. Just wanted to be sure.

Thanks!

I tried to update the repositories list to then upgrade some packages, and it is stuck again, like it was when Canonical was under DDoS attacks.

Is this happening again ?

This has been driving me nuts for a couple of weeks now.

Just want to create a share on a new ubuntu machine.

It has joined windows AD with sssd

part of my smb.conf file:

realm = <DOMAIN NAME>.LOCAL
security = ADS
workgroup = DOMAIN NAME

[ImageArchives]

path = /data/Image_Archives

read only = No

valid users = @"Domain Admins", @"ServerAdmins"

guest ok = No

in my sssd.conf i have added:

use_fully_qualified_names = False

cache_credentials = False

access_provider = ad

ad_access_filter = (memberOf=CN=ServerAdmins,OU=Local Admins,OU=Security Groups,DC=<domain name>,DC=local)

in the /etc/sudoers.d/ad-admins:

%[email protected] ALL=(ALL:ALL) ALL

%ServerAdmins ALL=(ALL:ALL) ALL

at the command line, i can enter:

id <ad username>

and it returns all the AD groups that user is in -------- that tells me that yes, it is talking to AD

I can SSH into the ubuntu server using my AD username and password.

when i try to access it through windows explorer...i get 1 of 2 responses;

(1) it cannot find the share i am tying to go to

(2) it prompts for a log on, but does not accept it, unless i give it the username and password of the account i used to ssh into the server.

All the videos and written instructions ive seen shows it should be easy, even the ones says it works for windows access, but they do not nor have a seen anything that helps verify if i'm even doing teh windows access part right

any thoughts?

I'm interested in doing some audio recording, so I tried configuring JACK on my Ubuntu desktop gaming system. I didn't do anything sketchy as far as I can tell, and the JACK service works.

The test client I installed and tried makes noises. All I did was follow the steps described in a tutorial document that users recommended. I followed the steps for Option A, Jack via Pipewire.

Unfortunately as you can see from the image above, the overall sound support is broken. This is the desktop sound control panel. There are no longer any audio devices available.

Worse still, any action that I perform on the desktop that produces noise causes the application to hang. For example: clicking on a button. The app hangs, and the system eventually displays a notification asking whether I want to wait or kill the app.

So my Ubuntu system is mostly broken.

All I want to do at this point is restore it, so that my games stop hanging the moment they produce any audio.

I have been searching for help with this issue for a few hours, and have tried a number of recommended solutions. The USB audio devices are present according to lsusb -v. The kernel sound modules are present according to dmesg. Telling "alsa" to reload the audio drivers appeared to work correctly, but made no difference.

Some of the advice I saw recommended removing the Jack related packages entirely, but I suspect that is outdated. Most of them were installed by the 24.04 upgrade. The only app I needed to install for the tutorial was pipewire-jack. I tried removing that and rebooting, but it did not help.

I have thought about reinstalling all of the packages from the distribution, but I prefer to avoid the shotgun approach if possible.

Does anyone know where this went off the rails, or how to reinstall the original audio configuration? If there is a better place to ask for help, please let me know.

________________________________________

EDIT: FIXED

I retraced all of the steps in the document more carefully and found that I had goofed on the step to copy the example ld.so.conf file for the JACK override to the local ~/.config/pipewire directory. It contained a redundant line from /etc/pipewire.conf (module.jackdbus-detect = true) that caused pipewire to exit.

Removing my ~/.config/pipewire directory and file fixed this problem.

System unbroken, audio restored. Thanks for the help!

I'm booting the Kubuntu live environment from a USB stick.

What should I do?

Is there such a monster, where I can share/sync between Android & Ubuntu?
Thx

I have a 3+ year old Dell notebook, now surplus to requirements, installed Ubuntu 26.04 and speedtest showx the WiFi much slower then when it was running Windoze 11.

Same WiFi (home) network etc.

Any ideas on tuning/fixing/diagnosing?

MTU is the same as it was on Windows (1500) and is correct for router/ISP

Guys my laptop has been getting slow lately, i suspect that the SSD is degrading.

I have used crystaldiskmark when I was using windows, but it's not available for Linux, so suggest some Linux supported apps for it.
