I'm running Ubuntu 24.04.4 LTS x86_64 with NVIDIA Geforce RTX 3050, driver version 570.211.01. It boots to an X11 session. I don't recall disabling Wayland, but I'm not 100% sure. File /etc/gdm3/custom.conf has the original line #WaylandEnable=false. Login to Wayland session results in X11 session running instead.

Is X11 forced by Nvidia driver? What is an easy way to get a Wayland session?

The message, which does not interfere with the package update process, is as follows:

I have a Ubuntu 22.04 system with multilib installed and I am trying to build a 32bit application that needs libcurl. The only version of libcurl on the system is the 64 bit version. I have tried to install the i386 version using "apt install libcurl4-openssl-dev:i386", but it says it needs to uninstall the 64bit versions of the many packages. I need to be able to support both 32bit and 64bit packages. Is there something that I am missing?

This is the response that I get when I try to start Gwenview in Terminal: $ gwenview

/snap/gwenview/148/usr/bin/gwenview: error while loading shared libraries: libPlasmaActivities.so.6: cannot open shared object file: No such file or directory

Do I need to redirect the path somehow? It worked well before updating to 22.04.5 LTS

Thanks for any response.

I am experiencing a persistent issue where Bluetooth cannot be turned on in my Ubuntu installation, despite working perfectly on the same machine in Windows 11. The service is active, but the hardware is not being detected on the USB bus.

Hardware details:

• Motherboard: ASUS B650-E WI-FI

• CPU: AMD 9700x

SOftware details:

• OS: Ubuntu 25.10. Note that i just updated from Ubuntu 25.04 but i don't recall if the bluetooth was working before as i did not use it.

• Kernel: 6.17.0-19-generic

The Symptom:

• lsusb | grep -i blue -> (No output)

• bluetoothctl power on -> No default controller available

What i tried:

• Disable windows fast boot

• Disable Bios erp setting

• rfkill list shows no soft or hard blocks

• sudo systemctl status bluetooth shows the service is Active (running).

• Attempted sudo modprobe -r btusb && sudo modprobe btusb with no change.

• sudo dmesg | grep -iE "blue|firmware|hci"

I have no clue on how to solve this, some help would be much appreciated :)

Need to know where or which chip is the BIOS chip in my Acer Aspire AOA150. I am upgrading the BIOS, ans since the old BIOS will not charge the battery. Since I use only Linux OS's and to flash the BIOS, the file is an .exe file which requires Windoze. So I am going to do a chip swap (unsolder old chip, clean the area, solder new chip.

I am pretty new with Docker and am hitting a problem I do not understand while setting up Immich.

I followed the official documentation; created the immich-app directory where I downloaded the docker-compose.yml and .env files, created two directories for UPLOAD_LOCATION and DB_DATA_LOCATION on the SSD in immich-app which I indicated in the .env file like so:

UPLOAD_LOCATION=/home/quieter3/immich-app/library
DB_DATA_LOCATION=/home/quieter3/immich-app/database_files

I also validated that docker.service is active and enabled.

When executing docker compose up -d, it starts pulling the details but stops somewhere while downloading and slowly, everything stops responding. I had to force shut down the machine.

EDIT adding details to error: Stops while pulling the images. Typing any command with CLI outputs "command not found", unable to reboot-shutdown normally.

I had this problem on Linux Mint and thought it was an issue of Mint not being officially supported, seems it is something else I have not yet figured out.

Any help/guidance would be well appreciated!

EDIT for machine details: MeLe Quieter 3C Fanless mini pc, Intel N5105 4 cores @ 2.0GHz, 8Gb RAM. Which is a bit more than the recommended specs suggested by Immich.

Does anyone have experience using the OWC ThunderBay Flex 8 (Thunderbolt 3) with Ubuntu 24.04 and Thunderbolt 4 drivers? I connected the Flex 8 to my Ubuntu system, but it is not being recognized.

My mother's computer is a 2GB RAM HP Steam, and as you can imagine it has been unused for a while. I am trying to give it a new life using Lubuntu. Everything is alright except for the Wi-Fi connection to the internet. It is my first time using a terminal and I have already tried multiple ways to update the drivers and none of them have worked.

I started here: Installing Broadcom Wireless Drivers and have been trying to fix the errors that appeared along the way until getting to this tutorial: https://forums.linuxmint.com/viewtopic.php?p=2749276#p2749276. And it still doesn't work.

Here is my terminal output.

Noticeable performance boost on Ubuntu 25.10 (Dell OptiPlex 3050)

Hi everyone,

I wanted to share some positive feedback regarding the latest Ubuntu 25.10 (Questing Quokka) release. After upgrading from 24.04 LTS, I noticed a significant and very obvious improvement in system responsiveness and overall speed.

The UI feels much "snappier," and animations are noticeably smoother on my hardware.

My System Specs:

• Model: Dell OptiPlex 3050

• CPU: Intel Core i5-6500 (Skylake)

• GPU: Intel HD Graphics 530

• RAM: 16GB

• Kernel: 6.17.0

• GNOME: 49 (Wayland)

Great job by the team on the optimizations in this interim release. It makes me very excited for the upcoming 26.04 LTS!

I use a Linux system with Ubuntu 18.04.5. Te file /etc/samba/smb.conf contains the rules:

client min protocol = SMB3

and

smb encrypt = required

The command nmap -p445 -Pn -vvv --script smb-protocols on this system gives (between others) the following output:

  Host script results:
  | smb-protocols:
  | dialects:
  | NT LM 0.12 (SMBv1) [dangerous, but default]
  | 2.02
  | 2.10
  | 3.00
  | 3.02
  |_ 3.11

Is that in contrast to each other?

In Samba it is set that the minimum SMB protocol is 3. nmap reports the dangerous SMBv1 protocol anyway.

Can the Ubuntu system still be accessed with SMBv1?

When I use regular or fractional scaling, content generated by Wine does not scale. This looks particularly bad under fractional scaling because the Wine content takes up relatively less of the screen.

No scaling, 125% scaling, 200% scaling. Adjusted for perceived height.

In other software that does not honor desktop scaling I have found an independent scaling setting for that software. (e.g. layout.css.devPixelsperPx in Firefox).

How can I set scaling in Wine?

In both my live USB (official 20.04 iso) and a fresh Focal install, Firefox reports a few different errors in the Browser Console every time it is launched. This happens with new FF profile, no add-ons, cookies etc. I've reset profiles anyways and it still persists. Booting firefox in safe mode does not do anything. I've updated/upgraded with apt & snap, the issue still persists. I tried FF on the live USB on two different computers and the same errors appeared. I've re-downloaded the iso and re-made the live USB, still no change. I think these may be unresolved low priority bugs but I cannot find ANYTHING online regarding them, which I find surprising if they were common bugs.

These errors are not causing any issues per se (although I do see error messages frequently when browsing and especially so with any add-ons). However, I've spun my wheels long enough that I need some sort of closure haha. Are these just bugs? Does anyone else get these same errors? Is there some underlying issue that I could fix besides my anal personality?

In 18.04 I had a launcher in the Dash to run an application in a terminal with the Dash showing an indicator dot for the launcher when it was running, rather than an indicator for the generic terminal launcher (this way I was able to find it if other terminal windows are open). I was able to use the --class option in the Exec entry along with StartupWMClass to achieve this.

In 20.04 the launcher doesn't work in that a terminal is opened, the application tries to launch and then the terminal closes. I googled this and there is some chatter about the --class option being depreciated. If I delete the --class option the launcher works, but the indicator dot is attached to the generic terminal launcher.

Here is the .desktop file before deleting the --class option

I just installed Kubuntu 18.04.

And for some reason I'm stuck on 1024x768 but my monitor is 1400x900.

I can't change it in the settings. When I try to use Xrandr I get

xrandr: Failed to get size of gamma for output default

Xrandr says the maximum is 1024x768.

Is this a plasma thing? What do?

Help me with this issue.

I installed Ubuntu on my Windows 10 laptop via the Windows Subsystem for Linux.

I have a NAS drive connected to my home Wi-Fi network. There's a "share" on it, accessible at \\MYCLOUDEX2ULTRA\Home that I've also mounted in Windows as my Z: drive.

When I start up the Ubuntu console, if I go to /mnt/ I can see c and d directories there (for my laptop's local hard drives), but how can I navigate to my Z Drive?

To upgrade from 18.04 to 18.10 I executed the following commands: "sudo apt-get dist-upgrade" and "sudo do-release-upgrade"

Upgrade proceeded normally until the system reached the reboot phase. Following reboot the normal maroon dot progress screen was displayed for a few seconds. This was replaced with a black screen with the message "Main-Linux clean 574402/3567072 files, 7146011/14350592 blocks". And there it stopped with no further changes evident.

Ctrl-F1 took me to the normal console log in. I could log in and found everything was running normally. Disks were all present, active and with plenty of free space. Ctrl-F7 took me back to the black screen with the single message at the top of the screen.

I tried booting with the previous kernel but got the same result.

I have a spare 18.04 Linux on another partition. After booting into it a cursory look at my main system showed nothing untoward.

I have successfully upgraded Ubuntu for more than ten years and this is the first problem I have experienced.

Where do I go from here? How do I fix the problem?

Edit:

After booting into my spare Ubuntu 18.04 on another partition I used the Disks program to do file system checks on the main partitions. This reported that the file systems were clean. I then tried to reboot into 18.10 but again got the same problem, described above.

I have checked the SMART status of the SSD and it reports all is OK after self-test. The processor is Intel Pentium(R) CPU G4400 @ 3.30GHz × 2 and the GPU is Intel HD Graphics 510 (Skylake GT1)

Update:

After logging in at the console(Alt-Ctrl-F1) I can start the GUI by entering startx. For some reason the GUI subsystem fails to start automatically, as it did before.

Running Ubuntu 18.04 on a non-headless server dedicated only to cryptocurrency mining.

The server, after some moments of mining, beeps and reboots. While it does that, there is some kind of error message that I can't get to read, is a lot like if you blink it you'll miss kinda thing. Lasts less than a second on screen before rebooting.

I've tried checking every log at /var/log and also journalctl looking for this error message with no luck. Tried to log all the output of the miner to >> minerlog.log with no luck. If i SSH to the server through putty, the error message is not shown, so logging a putty session doesn't work either.

My question is, then, is there a way to log all the text displayed in the monitor to a file so I can check lather what's that error message? Or if a log like that already exists?

I have been using a program on my Windows computer for quite some time, but I am using my Ubuntu pc the most these days. Thus, I would like to be able to run this program (.exe file with associated .dll files) on my Ubuntu pc, but I have already given it a try myself using mono, however, this failed. Not sure if this is important, but the program requires the .net framework, which is why I chose to use mono.

I installed mono like this: Tutorial on how to install

The problem is that when I use the command mono /root/myprogram.exe, it prints out the error "file does not contain a valid cil image". What can I do?

I'm trying to write a program that transfers data to my device. I'm using libusb. I had many problems to install its package in both 32 & 64 bit edition of Ubuntu 16 LTS. Commands for installation:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install libusb-1.0-0-dev
sudo apt-get install libusb-1.0-0-dbg

also tried: http://www.linuxfromscratch.org/blfs/view/svn/general/libusb.html

"dpkg -l libusb*" in Ubuntu 64 bit; shows that it has been installed while 32 bit one announces "no such package...".

Compiling command:

sudo gcc -g -o usbtest usbtest.c -lusb-1.0

In Ubuntu 64 bit it compiled while in 32 bit one, following note appeared:

/usr/bin/ld: cannot find -lusb-1.0
collect2: error: ld returned 1 exit status

but I was sure that it exist then I tried following command and it compiled without any error.

sudo gcc -g -o usbtest usbtest.c -L/usr/local/lib -lusb-1.0

at the end when I execute my program, it can not find my device in other words can not open the device. following presents debugging procedure in Ubuntu (32 & 64 bit):

141      int r = 1;

I'm unable to use my touchpad as well as my USB mouse once I suspend or put my laptop on hibernate. How do I fix it?

Once the laptop goes to sleep, I'm unable to perform a button click using the touchpad / USB Mouse, and my laptop has a touchscreen that's also not working. Only the Button Click event does not work. Otherwise scrolling and everything else works fine.

Wayland is the default display server for Ubuntu 17.10 "on supported systems". But how can I tell if my platform is supported and I'm actually using Wayland?

I am trying to compile this program called Doppia and it requires an older version of Boost (somewhere around 1.54 - 1.55) however when I try to install it using

sudo apt-get install libboost-all-dev

it installs the latest version while

sudo apt-get install libboost-all-dev=1.55.0.2

does not find any package. Is there any way to install an older version of a package without having to re-compile it?

Thank you.

I updated to Ubuntu 15.10 but it causes a huge issue for me: sfdisk doesn't work anymore.

I really need sfdisk to build partitions on SD card for my embedded Linux but it seems that options have changed.

Version:

sfdisk from util-linux 2.26.2

I have an early 2011 macbook pro.

My primary hard drive location has a mac os X yosemite installation.

I replaced the optical drive with a secondary hard drive, which has two partitions created with bootcamp: (1) Mac OS X Mavericks and (2) Windows 7

I followed official ubuntu instructions for creating a bootable USB stick on Mac OS X.

When I reboot the system holding the option key, two new boot disks appear with the USB logo. Both titled "EFI Boot". I click on one and it takes me to the Ubuntu menu. When I select "try ubuntu" in order to use a live installation, I then get the message ''i8042 No Controller'' and the system hangs. I then have to use the power button to reboot. Any idea as to how to get around this?

If I select install ubuntu, I get the same error.

I am trying to recover a disk that has corrupted superblock but I cant seem to unmount the disk at all. I used bcache for the three extra drive after a reboot one of the drive stopped working. so I removed the SSD cache drive and still cant seem to recover the drive

Hi. I've got a working Ubuntu 12.04 server, which is going to serve as media server. I've added two disks of size 3TB to put my data on, and I wish to combine these as one 6TB logical volume which I could mount under /media.

So far, I have created one partition on each disks with fdisk and formatted them to ext3. But now I am stuck on how to continue. Do I use Mdadm to create a Jbod array? Or do I use LVM to make a logical volume of these two disks? I can't seem to find the documentation I need, it's mostly about extending existing volumes or installing a fresh system which I don't need.

My OS is on /dev/sdc1 (it's a USB thumb-drive), and the two newly created partitions are on /dev/sda1 and /dev/sdb1.

Hope you can give me some directions.

I have a system where all the partitions (/, /home, and swap) are encrypted except for /boot. /boot resides in an external device which also contains a set of encrypted key files used to automatically decrypt all of the partitions. In other words, my desired end result was to have 2-factor authentication using an external device and a password where the password would be entered once during boot and the boot scripts would use the password to decrypt all of the partitions.

I'm a newbie to Ubuntu (and Linux in general), but I did some trial and error modifying the various scripts found in initrd.img using update-initramfs. The cryptroot script seemed to be doing all the work mounting the partitions at first, but after some experimenting, it appears that it is only responsible for decrypting the root file system. I had modified a string in the script changing Enter the passphrase to simply Password, which appeared to work when decrypting the root file system, but used the old prompt again for decrypting the next partition. In other words, this is what I'm getting:

1. cryptroot script loads.
2. The script asks for a password to decrypt the key partition and mounts it.
3. The script calls the setup_mapping function to decrypt the root file system.
4. The script tries to read the key file from the key partition to decrypt the root file system.
5. The root file system is decrypted and mounted.
6. The system prompts to enter a passphrase to decrypt the next partition…

I think Ubuntu might be running another copy of the cryptroot script somewhere to decrypt all the other partitions after root, but I don't know what else to modify.

How do you create a custom application launcher in Gnome Shell?

I have a local Eclipse installation that I'd like to be to quickly launch. So I created a symlink to the eclipse binary and placed it on my desktop. If I open a terminal, cd to ~/Desktop and run ./eclipse it starts Eclipse perfectly. However, if I click the Eclipse icon on my desktop, and choose run, nothing happens.

Alternatively, I wouldn't mind being able to search for Eclipse on the "Activities" screen, but I can't find any documentation on adding or registering custom applications.
