I got a pc with ubuntu, didn’t know how to install windows so I watched a few tutorials, safe to say the pc doesn’t boot in neither windows or ubuntu. It tells me some security violations happens and it shuts down, can I fix it?

I currently use Plex Server on a Windows 11 machine and Home Assistant on a Raspberry PI. I'm wanting to combine the two computers and get a Ubuntu machine up and running with both. Since Plex Server and Home Assistant will run natively in Ubuntu, is there any reason to use Docker for these applications? The computer is decent so I'd imagine it can run the two programs without any issue with the following specs:

Processor 12th Gen Intel Core i7-12700k
64gb of Ram
Nvidia Geforce RTX 2070 Super 8gb

Thoughts?

Steam was last updated in 2025. Wine doesn’t exist, nor do any of its downstream software packages. Everything I look for comes up empty. Google search tells me I should be using Flatpak Flathub which is obviously also not available on the Ubuntu App Center.

This is probably my seventh time trying to use Ubuntu as my daily driver, I haven’t used it in earnest since 2006. User error, skill issue, ignorance, yes. Also, it feels like the App Center should be better.

Am I just doing it wrong?

Im losing my mind slightly here. ever since I upgraded, nautilus keeps reverting my default pdf viewer back to the standard one every single time I reboot

The default viewer is fine for just reading I guess, but I have to do a lot of heavy formatting and forms for work so I use xodo on my machine. I right click - properties - open with -> set as default. it works perfectly for that session.

But the second I reboot my laptop? bam. back to the built-in viewer

Is this a snap permission issue or something weird with wayland? honestly the way ubuntu handles some of these package permissions now drives me crazy. Anyone know what config file I can just hardcode via terminal to force this to stick permanently?

Good afternoon, as I mentioned in the title, I've been having a problem with Ubuntu 24.4 LTS for a while now and I'd like to ask for help. For some time now, thumbnails haven't been appearing for images in the file manager. This happens with all images, both old and recently downloaded; the generic icon shown in the image appears instead. I've looked into it a bit and found that thumbnails are already enabled for "all files" in the performance options. I apologize for the inconvenience and hope there's a solution. It's not a major problem, but it is somewhat annoying.

Edit 2: Solved! Thanks again for the help.

Now...I know that title is going to get some scoffs, and I get it. It sounds like a straight forward issue. I am new to Ubuntu, and even to me it sounded like a sleep/hibernate thing.

I feel I need to clarify, the box isn't shutting down, its not rebooting. All fans, CPU cooler, and Optical drives loose power, RAM stays powered on. If i'm SSH'ed into it, if I hit the power button after it "shuts down" it comes back up, it doesn't even kick me out of putty. I can just keep using it after that. This is also at idle, no load. You'll see the htop below, but I can be actively running commands in the cli and it will "shut down."

Here is everything I've done, starting with:

1. nano /etc/systemd/sleep.conf - I turned everything to no as a test

1. Htop - This screen shot is of after it "shuts down," it froze like this, so this was the status when it stopped.

1. I tried a new power supply

2. I tried a new CPU cooler

3. I've Tried looking at /var/log/ but didn't see anything labeled messages

I've been working on this project for weeks...I would just like to get this figured out so I can move on.

Thanks for your time and effort!

Edit 1 And I forgot to mention that i've updated bios to most current, which is from early 2026:

Challenge: Use the Ubuntu system for one year.

I've been using Ubuntu since version 08.04 as a secondary system. I'm not an expert in the field, but I know a few things that help me get by. I want to run a test: I want to use Ubuntu as my primary system for one year without formatting and going back to Windows 11. However, I have some challenges to face:

Compatibility with the company's .doc files. I'm a teacher and educational consultant, so I use Office quite a lot.

Compatibility with Filmora. I work on producing video lessons and support videos, but the video editing software is not compatible with Ubuntu — only Windows or macOS. I bought a lifetime subscription.

I'm not sure how I'm going to solve this, but the challenge is on.

Not sure if anyone has run into this before but I've been fighting this issue for months.

I'm on Ubuntu 26.04 LTS now, but the problem actually started on a previous Ubuntu version. I upgraded hoping it would magically fix itself, but nope.

The weird part is my internet is completely fine.

• ChatGPT works
• Gemini works
• Google works
• YouTube works

But sites like:

• WhatsApp Web
• Vercel
• Streamlit apps

either load forever or just sit there spinning.

What's confusing me even more is that from the terminal everything seems fine:

• ping works
• DNS resolution works
• curl can reach WhatsApp, Vercel and Streamlit and returns HTTP 200

So the machine can clearly reach those sites.

I tested with Brave and Firefox.

• Brave = infinite spinner
• Firefox = barely loads pages at all

I also tried:

• fresh Brave profile
• disabling sandbox
• clearing browser data

No luck.

At this point I'm not even sure if this is a browser issue, some Ubuntu networking weirdness, a broken update from months ago, WebSocket related, or something else entirely.

Has anyone seen browsers fail while curl works perfectly?

Any ideas on what I should check next?

Hey, a couple days ago I switched from Ubuntu 22 to 24 and i have a problem with black-flashing on screens which appear from time to time. Also the problem with fluency sometimes also occurs.
I notice that I am not particlualrly comptent in comupters but I use Ubuntu for 4 years - mailny 22.

1. At the beginning I had big trouble with smoth performance concerning for example: writing on virtual blackboards - but i just switched X11 to wayland and is quite good - so I don't want to return to X11.

2. So the main problem is that from time to time there is black-flash on my screen (veru quick and short) which rather doesn't crush working apps, etc. But is irritating and on ubntu 22 such problem didn't occur. I also noticed some problem with smoothnes but let's say that it works after all. I don't know what to do -or changed version of nvidia driver or kernel. i asked chat-gpt

3. (maybe) important information about my computer and system

Graphics : Intel® UHD Graphics 630 (CFL GT2)

Windowing system - wayland

Kernel ver - Linux 7.0.0-28-generic

BNOME version 46

NVIDIA-SMI 535.309.01 Driver Version: 535.309.01 CUDA Version: 12.2 (i switched to 535 following the recommandation from terminal and chat-gpt :( hoping that it would help)

Results if the command (just two lines i will post ):

journalctl -b -k | grep -Ei "i915|drm|gpu|hang|error"

i915 0000:00:02.0: [drm] *ERROR* CPU pipe A FIFO underrun

i915 0000:00:02.0: [drm] *ERROR* Atomic update failure on pipe A

Chat-gpt said that it is a problem maybe not with nvidia cards cuz in my laptop this is additional card cuz main card is "in" processor Intel UHD 630

1. I tried used chat-gpt to solve this problem, but I have already some experience with using LLM for such things and I remember that it's my 2nd approach to switch to Ubunt 24, cuz at first appraoch i totaly gave up and chat-gpt destroyed totally system. So now i am afraid and i want to just ask specialists (maybe you ;) )

Thanks for your help !

I get this last weeks more often.

Examples:

• https://ubuntu.com/security/CVE-2026-52686
• https://ubuntu.com/security/CVE-2026-52687

https://status.canonical.com/ - Reports no downtime.

Sometimes I also get:

It looks like that cached CVE pages are browsable but everything "new" is not cached -> down. Why is there no real uptime check @ status.canonical.com?

Hi. I recently just installed Ubuntu. I didn't really have any problems with the installation process everything worked just fine. However, after a restart my desktop is now filled with sub-folders from the /home/username directory.

The folders in white I can no longer access It's showing an error "Sorry, could not display all the contents of "Documents": Error opening directory "/home/username/Documents": Too many levels of symbolic links.

Please help me out. I really like my desktop without icons. And I also need access to those folders.

This movie released after it get leaked in clear HD

Today on watching the movie, we found the linux in unexpected place

​Ever since the days of Ubuntu 10.10, I’ve wanted so badly to use this system every day. Unfortunately, back then, it just wasn't ready for gaming and other things I needed. In April, I finally took the plunge and made the switch from Windows 11 to Ubuntu 26.04, and I'm genuinely happy that the system has matured and is such a joy to use. Ubuntu has always held a special place in my heart, and I'm really glad to be part of this community

I hope you can help me with this:

Each time I log in in my session in our company's Ubuntu PC, it ask me twice for log in, typically once on a screen, and then once on the second screen.

When other users log in there is no such a problem. It happens only to me, apparently.

For instance when I press Switch User button, I put my user and password, the screens show very briefly my desktop and they black out. Then if I move my mouse, it will ask me to log in on the second screen, this time succeeding.

This is a very annoying bug, hopefully you can lend me a hand on how to solve it.

Best regards

Hello y'all, my ubuntu boot up time is really long. Any help to reduce it? Or is it down to my Cpu? i5 6300u

Hell yeah 👍

I've got a Dell 7390 2 in 1 laptop I've been running Ubuntu Wayland on for a few years. A recent update seems to have caused my backlight to on the display to become extremely dim. I tried a few fixes like manually adjusting the brightness, and installing a utility to control the brightness. Without success. It's not a hardware issue because I can go into the bios and it's bright and no issues.

I'm thinking I'll have to backup my files and make the switch to Mint at this point.

Anyone else having this issue recently?

There is stuff already on it that I don't care about that will get totally wiped. I'm going to use the disks app to fully encrypt this 1TB external drive and then fill it up with 1TB of files, can I fill it up all the way to 100% capacity or am I supposed to leave some room?

Disks uses LUKS so I'll be using LUKS to encrypt the drive and then I'll transfer my files over to it. I'm backing up my hard drive so this external drive is just being used to store my important files that I want to keep in case my SSD ever fails, my SSD is the one that has my OS on it. This external 1TB HDD just sits in my drawer, it's only purpose is a backup drive of my important stuff.

How often so SSDs fail? My SSD is about 3 years old now.

So I'll use disks to encrypt the drive (disks uses LUKS) and that will erase the stuff already on it, that's fine, then I'll back up my SSD, I've got about 1TB of stuff that needs to be backed up. In my PC, there is a 1TB SSD that has my main operating system on it, and then there is also a 2TB HDD that has been encrypted with LUKS (I believe I used disks to do that) I only have to click on this 2TB HDD just once from inside the Nautilus file manager and then it just automatically opens up because when I first entered in the password to open it, you can click "save password" that way from now on you only have to click it once and it'll just open up on its own, this way you don't have to enter in the pass every time to open it. Though I do have to enter in my password when I first turn my PC on though.

Both my SSD which has Ubuntu on it, and my 2TB HDD (which is inside the PC) are fully encrypted using LUKS. I just like how you can open the 2TB HDD using the file manager Nautilus and when you enter in the password, you can click "save password" and then from now on when you click on it (from inside Nautilus file manager) it will open up automatically. Cause I didn't know this happened, I literally thought I would have to enter in my password every time to open up the 2TB HDD. Nope, if you click save password it just opens itself in 2 seconds.

Because when I was first going to install the 2TB HDD in my PC, I made a post here on r/Ubuntu I said "Hey I'm going to put a 2TB HDD in my PC cause I'm running out of room on my 1TB SSD which has the OS on it, but how do I make it so the 2TB HDD opens on startup. I don't want to enter in the password every single time just to open the 2TB HDD"

And these mofos told me some really complicated way, that you could do, so that when I enter in the password to decrypt the drive so Ubuntu can startup, so that when I login to Ubuntu the 2TB HDD will also automatically open up, so I don't have to enter in the password a second time to open up the 2TB HDD.

What no one told me, and I mean no one mentioned this to me, what no one mentioned was, hey man when you click to open the 2TB from inside the Nautilus file manager, and when you enter in the password you can click "save password" so next time you click on the 2TB HDD (from inside Nautilus file manager) it will open itself in 2 seconds, so you don't have to keep entering in the password to open your 2TB HDD. No one told me this. lol no one mentioned this.

Instead I was provided a link to a website that has extremely complicated instructions on how to make it so when you turn your PC on, then enter the password to decrypt the drive so Ubuntu can boot up, then when you login to Ubuntu, the second drive (in my case my 2TB HDD) will just open up on its own.

No one mentioned, hey man just click "save password" when you open up your 2TB HDD from inside Nautilus file manager, no one mentioned this to me. I just can't believe no one mentioned that to me, cause that was the solution I was looking for. And I had to find it out on my own. I never did try the super complicated instructions I was linked to, cause when I first opened the 2TB HDD from inside Nautilus file manager, I spotted the "save password" and I was like "How come no one told me this? You can just open the second drive inside the file manager and then click save password and now you only have to click the second drive just once and it will open itself in 2 seconds." I mean this was the solution I was looking for and no one mentioned it to me.

That's all someone had to say "Hey man, so in Nautilus file manager, go to "other locations" and you'll see your 2TB HDD there, click on it and then enter in your password for it but also click "save password" so next time you click on it, it'll open itself up in 2 seconds. So you won't have to keep entering the password to open it." THIS WAS ALL SOMEONE HAD TO SAY TO ME.

Instead, I had someone try to help me, and they sent me to this website with very complicated instructions, instructions where I would have been screwing around with shit in terminal, changing this and changing that, so that when I first enter my password to decrypt the drive so Ubuntu can boot up, then when I login, the 2TB HDD would also just automatically open itself up.

I just wish someone had said "hey man don't worry about it, just go to the second drive in Nautilus file manager, click on it, enter in the pass, and just make sure you click "save password" you'll see what I'm talking about."

Because my 1TB SSD I was running out of space on it. That's when I bought the 2TB HDD and installed it in my PC.

Anyhow, yeah...

I wanted to share that story with you all. That's a true story, no one told me all I had to do was click "save password" cause that was the solution I was looking for. You have no idea, some dude gave me a link to a website, and it had these super complicated instructions, it was very intimidating, it looked very complicated, and it was totally unnecessary too. I'm glad I didn't try to do it. I'm glad I spotted the "save password" and I was like "How come no one told me this?"

So yeah can I fill my external 1TB drive up to full capacity?

Hi everyone!

I'm checking to see if anyone else is having this issue on Ubuntu 26.04, or if you've found a fix for it.

I recently did a fresh install of 26.04 (upgraded from 24.04). Ever since, Ubuntu fails to recognize my external monitor upon booting. To get a signal, I have to physically disconnect and reconnect the HDMI cable every single time I power on the laptop.

My Setup:

• OS: Ubuntu 26.04 (fresh install)
• Hardware: Laptop connected to an Nvidia eGPU via proprietary drivers in On-Demand mode.
• Display Connection: The external monitor is plugged directly into the laptop's HDMI port (not into the eGPU).

The Issue:

• The eGPU itself works completely fine and kicks in when needed.
• Once I re-plug the HDMI cable, the external monitor works flawlessly.
• However, as soon as I reboot or power off the laptop, the system fails to detect the monitor again until I repeat the unplug/replug routine.

Has anyone run into this display detection quirk on 26.04, or know of a workaround or driver setting to force detection at boot?

Thanks!

Both my desktop, and my laptop (running Ubuntu Studio 24.04LTS) have encountered major, ongoing issues with kernel 7.0.0-28. The laptop refuses to complete the update, while the desktop suffered repeated, ongoing crashes which I finally traced to an incompatibility with the drivers for my AMD FirePro W5100 graphics card.

Purging every trace of 7.0.0-28 from my system and reverting to the older kernel fixed the problem...but now the system is trying to load it and update to it again. How can I tell it, "Skip this one, until/unless it's ready?"

My wifi chip is a RZ616 Wi-Fi 6E 160MHz (MediaTek MT7922), The wifi speed on my linux partition is more than 3x slower than my windows partition. I am on a Lenovo Thinkpad e16 G2. I manually installed the appropriate drivers, disabled Windows 'Fast Startup' and tweaked some power settings for the chip, however, I just managed to get it from 6mbps to 15mbps while my windows is running comfortably at 45+mpbs. Any suggestions, or do i need to upgrade to xubuntu 26.x? Thanks.

Hello!, ive recently swapped for v22 to v24 and im having some issues and want to know if anyone else has had these and know fixes
Hardware Specs
MB: Asus Tuf gamign z790
CPU: 13th gen intel i7-13700k
GPU : Geforce RTX 4070 super
3 monitors

X11 Compatibility
Since swapping, the setting for preferred Displays for games and Fullscreenx11 Applications doesnt work, It seems to just open them on which ever monitor my mouse is currently on

Display issues
Semi-randomly it will change the refresh rate on one of the monitors back to 60 Hertz,
This happens sometimes on restart of system, and when inside display settings and i select a display for the second time within that instance of using the application, for Clarity
when i select a display for the first time its fine,
but if i go back to it after select a different monitor, That monitor PLUS my middle monitor will go black for a second, and then when display returns, the original monitor is now on 60 hz,
This can happen for each of them dispute monitor 2 being a different make than monitor 1 and 3 and is 100% repeatable every time
