The Issue

I get blue colored window border for some apps. I installed Spotify, and Brave as deb packages. Still I get this blue border. I have also find the same issue with Snap and Flatpak versions of spotify-client. See the screenshot:

What is the reason of this problem? How do I fix this? Do all users face this? I face this from before upgrading to Ubuntu 26.04 LTS. I recently upgraded, but the issue is still there.

I have reached out to everyone i can so this is my last hope. I need Ubuntu Pro Licenses for 2 22.04 LTS and 1 24.04 LTS servers run on AWS Lightsail but i cannot find where to get them.

AWS Marketplace does not support Lightsail Canonical have not got back to me after chasing multiple times and any advice will be handy as i need this to complete my CE+ Cert.

I am unable to boot the Live USB of Ubuntu Cinnamon 26.04 on a Dell Optiplex 7050 Micro (Intel HD 630). The boot process hangs indefinitely after "Get:6 file:/cdrom resolute/universe...".

I have tried the following without success:

• Both UEFI (GPT) and Legacy (MBR) boot modes.

• Multiple USB sticks and flashing tools (Rufus, BalenaEtcher, Ventoy).

• Boot parameters: nomodeset, copytoram, pci=nommconf, usbcore.autosuspend=-1.

• Disabling Secure Boot, VT-d, and TPM in BIOS.

Older distros like Peppermint 10 boot perfectly on this exact hardware. There seems to be a major regression in the 26.04 kernel or dracut initialization for this chipset.

This is a major disappointment. I prepared this machine with a brand new M2-disk, and have waited months for the 26:04 to be released. The machine now goes back om the shelf while I wait for a fix. The plan is to test this distro on this machine in hope of that Ubuntu Cinnamon can take over all the machines here running Peppermint 10 Respin (with Ubuntu Pro) - until 2028 max. I can wait longer, but if this isn't fixed by the autumn, I will be very angry and inclined to look somewhere else.

I'm deeply disappointed and utterly broken after hours of trying and failing.

When can we expect the Ubuntu Server 26.04 LTS image in MS Azure?

Expected UX: I can minimize/close the notification area without instantly dismissing all the notifications. When clicking on date/time, the notification area is reopened with all remaining notifications.

The notifications area should have the possibility to dismiss notifications individually and also a possibility to dismiss all notifications.

I bought a new system with AMD Ryzen zen3 5500GT and an Asus prime b450 motherboard. I have installed and have been using Ubuntu for the past three years, but now I can't install it.

Today I downloaded an Ubuntu 26.04 stable ISO and created a USB installation image. I have tried to install Ubuntu from this. Everything is working fine, except Ubuntu failed to load firmware for Realtek PCI wireless WiFi adapter. While booting through USB I have seen the following error with a red line.

Firmware for Realtek wireless LAN not available.  

After installing Ubuntu and booting WiFi settings in unity desktop can't find any devices.

When I run the command nmcli I get this error message: wlan0 disconnected.

Please suggest how to install driver or firmware for Realtek PCI wireless WiFi adapter 8192EE.

Yesterday I installed Ubuntu 26.04 on my quite old HP ProBook 650 G1 4GB/128GB, and I got this message when installing Ubuntu. It works from a live USB. I am a newb to Linux. Do you have any suggestions on how to overcome this?

I have/had this very annoying issue with Ubuntu 25.xx 26.04, Fedora 43 & 44 Desktop/workstation. (NO DUAL BOOT). every time I power on my laptop, OS stuck on grub or black screen. I have to remove my USB mouse (Logitech G502 hero or Fantech x17 blake) to boot in to the OS. I tried every solution I could find on the internet but none worked, tried different usb ports but no luck, disabled TPM, secure boot, USB boot and virtualization but no luck again. BIOS is up to date. When I remove mouse and connect any USB device, like, external HD or flash drive, then it works fine, no issues, Ubuntu and Fedora don't like my mice I guess. I have HP Envy x360 convertible 15-ds1063cl, AMD Ryzen 5 4500U, Intel NVMe, Micron 8GB RAM.

Thanks for reading.

my computer is a Samsung Book 2 Pro 5G. The following System program problem detected message appeared while installing Ubuntu Desktop 26.04.

Just installed 26.04 showtime is showing me this plugin missing issue but I've downloaded the prop codes and ubuntu-restricted-extras.If I click on "try anyway" it works but it's an annoyance.

I was installing Ubuntu and noticed the option to encrypt the system, which made me wonder what exactly the advantages of encryption are. I have very little technical knowledge and I wanted to know what specific risks a non-encrypted system has, for example if another person obtains your computer. What data would they be able to access by having access to your hard drive? Would they gain access to profiles on websites or applications that you are logged into, assuming they do not have the password to the system profile? Are there any other reasons why you would want to encrypt your hard drive besides theft?

I have a Surface Pro 7. I ran do-release-upgrade and pressed y at the 3rd-party warning, but it gave up immediately after. It mentioned 3rd-party packages listing Firefox, Mesa, and NTFS -related packages. Another computer with a superset of mentioned 3rd-party packages upgraded fine, so I doubt a Firefox or Mesa problem. Removing NTFS didn’t work. How can I upgrade this tablet from 25.10 to 26.04?

I reinstalled Ubuntu 24.04 few weeks ago and have had no issues until today when all of a sudden image files only show generic thumbnail icon instead of image preview thumbnails. Here's what it looks like:

I've followed every suggestion and solution that I could find and the problem persists. Anyone have an idea of why this happened and a solution that works?

With Ubuntu 24.04, I used the Software & Updates app to set the update frequency, schedule updates or stop them completely and do updates manually. (This is a requirement I have since I have limited bandwidth.)

I did the same for Snap with CLI commands that are well-documented. But for others, I'm a bit lost as the Software & Updates app is gone now.

Also, I know the Software & Updates app can be reinstalled, for now. But I'd like to know an alternative solution first, since they might ditch the Software & Updates app altogether in the future.

I am new to Linux. I have an RX 9060 XT and encountering a Linux-only issue where the GPU fails to initialize, resulting in a black screen when the monitor is connected to it.

The GPU works normally in Windows, but on Linux it fails during kernel driver initialization.

System information

• Kernel: 6.17.0-22-generic
• Mesa: Mesa 26.0.0-devel
• Distribution: Kubuntu 24.04
• GPU 1 (dGPU): AMD Radeon RX 9060 XT (Navi 44)
• GPU 2 (iGPU): AMD Ryzen 7 7700 Raphael (integrated)

Problem description

When the monitor is connected to the RX 9060 XT and the system boots:

• No display output. Not even the installation screen. When installing kubuntu I only see the menu where it says "Try or install kubuntu", after that is just black screen. (After connecting monitor to motherboard I get display so I can proceed to install)
• It only works when monitor is connected to iGPU
• GPU is detected in lspci, but driver initialization fails

lspci output

cd linux-firmware
sudo cp -r amdgpu/* /lib/firmware/amdgpu/
sudo update-initramfs -u

• Updated system packages (apt upgrade)
• Updated linux-firmware
• Manually replaced AMD firmware from upstream linux-firmware repo
• Rebuilt initramfs (update-initramfs -u)

Verified BIOS settings:

• Above 4G decoding: enabled
• Resizable BAR: enabled

Also, I did not install any drivers from the AMD website.

What could be causing this issue?

EDIT

I have resolved the issue by disabling Above 4G decoding and Resizable BAR in BIOS.

Yesterday I installed Ubuntu 26.04. My local network is a file dump with OpenMediaVault. I configured anonymous login to access resources. I was able to access them from other versions without any problems, but now there's not even that option in Nautilus. There used to be an option to connect anonymously, but now there isn't. How can I fix this?

I just came from Windows and the this was the first problem I had to face when I booted the OS.

Whenever I got this problem in Windows (when installing custom OSs) I just googled and downloaded the drivers manually, and then it worked fine. Obviously it wouldn't work in Ubuntu, but I've been trying for hours to get and Bluetooth back following installation guides, but it still doesn't work. The only way I can access the internet is by USB tethering hotspot from a phone.

I hope someone helps me out because I just like the OS too much to quit just yet.

I cannot install the new Ubuntu with Hardware-backed encryption because of this error:

PCR_UNUSABLE
error with secure boot policy (PCR7) measurements: unexpected EV_EFI_BOOT_SERVICES_APPLICATION event for \EFI\BOOT\BOOTEX.EXE after already seeing a verification during the OS-present environment. This event should be for the initial boot loader.

I have reset the TPM and reset the secure boot keys, I have cleared the drive so it is completely empty.

I am using a Lenovo ThinkPad T14 Gen 1 (Intel Edition), I have disabled the Intel features like AMT.

Is there anything I can turn off to fix this issue? Anything will help.

I was trying to install Ubuntu 26.04 and I'm getting tons of error messages. I'm asked if I want to report them and send them to Canonical (I said yes). Then I proceed with the installation and choose my options. At a certain point, I get to a screen where the installation can't continue, so I have to stop. The next button can't be clicked. I've attached a screenshot. If anyone can help, thanks! Regards, PP

Can anyone recommend some good disk data recovery software for Linux? I have a 4 Tb disk that was my primary Ubuntu 22.04 drive about 3/4 full that has a damaged GRUB and wouldn't boot. I spent about 2 weeks trying every repair command line strategy Google could come up with without any success. As a last resort I re-installed Grub from the installation USB. Now it boots but doesn't access any of the 257,410 items that 'properties' describes as unavailable. I presume that means I have overwritten some or all of my root directory. I have a new installation of Ubuntu 24.04 on a different computer with a larger drive so I have a safe place to put any recovered files. My question is how do I get access to those files. All the recovery software that Google comes up with seems to be for Mac and Windows and runs on Mac or Windows. I have 5 different flavors of Linux but no Mac or Windows. Any suggestions would be welcome.

User68187 asked what flavors of Linux. Ubuntu22.04 and 24.04, Mint 22, and LMDE7; all in desktop PC's. LinuxCNC (Debian 14) and BeagleBone black (Debian 12.13),in two dedicated non-PC machine controllers.

@Will: Business and bank records from the 1980s to March of this year (copied forward from DOS and OS/2 originals). Mozilla/Firefox bookmarks from 2006 forward. Lectures, tutorials, music and other interesting stuff.

I am on Ubuntu 24.04. After a recent update, some of my files, including:

1. png image generated by one of my codes

2. Screenshots taken

3. Clean pdf files downloaded

have no preview thumbnails that were downloaded after the update was installed.. Older ones are still being displayed correctly. I tried the following commands:

sudo rm -rf \~/.thumbnails/\* \~/.cache/thumbnails/\*

and

sudo dnf install glycin-thumbnailer

but they did not work, and the problem only got worse after executing the first of the above commands, where the remaining thumbnails were also gone. I also tried nautilus-q but it didn't work.

I have my computer with the following settings:

UEFI

Sleep set to S2Idle (if it's on "deep" it never wakes up from sleep)

It sleeps fine, but it shuts down incompletely: the screen is off, yet they keyboard still operates and the power indicator is still on. What went wrong?

I'll have to stop using ubuntu if this isn't fixed soon. There's no way forced shutdowns every day is good for the computer.

I've hardcoded ("burned") subtitles in a mp4 file using the following command:

ffmpeg -i nosubs.mp4 -vf subtitles=mysubs.srt withsubs.mp4

However I unfortunately lost the original nosubs.mp4 file. How can I restore it from withsubs.mp4?

I want to do that for two reasons:

Firstly, in the workplace setting I never need or indeed tolerate HDMI output to broadcast my sounds at large. Secondly, there seems to be a bug in Ubuntu where when I plug in headphones, the system correctly re-routes sound from HDMI to laptop, but towards speaker not headphone - still broadcasting at large; I hope disabling HDMI will get rid of that. So I need to disable specific sinks instead, because of integrated chipset.

It looks like not only Pipewire has new bugs Pulseaudio didn't, but it also has no GUI or even command-line tuning (wireplumber exists but has laughable cmdline and no GUI), instead user is expected to write json files to their dot dirs to configure. I would prefer a console or GUI tool, but JSON writing recipe is not off limits.

I've reviewed existing popular answers:

• Disabling port switch looks wrong because I still want switching between headphones and speakers, just never HDMI;
• Blacklisting snd_hda_codec_hdmi does not work - upon reboot the module is still loaded and HDMI sinks present; even if it worked, I believe it would disable the entirety of Meteor Lake controller, including speaker/headphone.
• I am using Meteor Lake super integrated chipset, meaning there's not two separate audio controllers but a single one - so there is no option to disable separate HDMI controller entirely:

Before the last shutdown of Ubuntu 20.04 my storage space of disk was very low, then after starting my laptop this error occurs.

Error: no partition found

Under Ubuntu 18.10, Ubuntu 18.04 LTS, and Ubuntu GNOME 16.04 LTS, I used the method described in Nautilus - Thumbnailer for Ms Office documents to successfully generate thumbnails for Microsoft Office (.doc, .docx, .pptx etc.) documents.

Now, in Ubuntu 20.04 this does not work anymore. I gave a look at the msoffice-thumbnailer script and it seems to me that the problem is related to wrong paths generated in /tmp directory.

Please help!

I recently wanted to add a skin to Audacious, but when I went to add the skins files to the skins folder I was denied the action. Was greeted with "You are not the owner. You can not modify this folder"

I thought root had these privileges? Wasn't I automatically made the admin of my laptop when I installed Ubuntu? I am logged in to the admin account, not as a guest.

Hardware:

• Intel i7
• AMD Radeon HD 6970
• SSD with plenty of space
• 6 GB RAM

Software

• OpenJDK 6, 7, and Oracle Java 7 (reproducible with all three)
• AMD Catalyst 12.8 and open source driver (reproducible with both)
• Ubuntu 12.04 x86_64 and older
• Minecraft 1.3.2 vanilla and older

On this setup I am getting rubbish frame rates after a short while of playing, dropping from about 45-55 to 15 in a couple of minutes. CPU use is 40-45 even when rendering the opening screen at 1920x1280, and gameRenderer is using about 90% CPU when playing.

Rather than trying to eke out a few more FPS out of an obviously broken rendering pipeline, I really hope to find a solution to make the GPU render Minecraft.

Edit 1: Something bizarre just happened: The first thing I always change in the settings is to turn bobbing off. Turns out that re-enabling bobbing makes the frame rate shoot right back up from 15-20 to 30-50 (mostly around 30) in fullscreen mode! It is still rather erratic, bumping down to 15-20 sometimes, but usually only for a few seconds. Also, the debug mode (F3) shows that 100% of the time is spent in "unspecified".

Edit 2: That seems to have been a dud - I disabled bobbing again a few minutes later, and it's been running at 20-40 FPS since. The snooper reports 24 FPS.

This is related to the issue discussed in Wireless mouse temporarily freezes (sleeps) on battery power.

Summary: the mouse freezes when operating on battery since it is autosuspended after a certain time and needs more time to wake up.

Disabling USB autosuspend for the mouse's receiver in PowerTOP is a temporary solution, but it does not survive a reboot.

How can I permanently disable the USB autosuspend for only one specific device?

A solution that does not involve installing additional packages is preferred (after all, I want to disable something), but it is not required. Removing PowerTOP (which seems to be a solution for some) is not what I want - I like PowerTOP...

And installing laptop-mode-tools to disable USB autosuspend altogether is not what I want, either, thus the new question.

Also: Will this affect the battery of my notebook? The Logitech unifying receiver for the mouse stays connected all the time, so if that prevents the autosuspend from happening for all devices that would probably be bad.
