Ubuntu 22.04 with Cinnamon desktop. I do something with the mouse, like my hand is shaking (my hand shakes, I'm older) and I move the mouse laterally by 1 mm at the same time as a click, and that is interpreted as a drag & drop. Sometimes I move the mouse cursor to the edge of the window or screen and the drag & drop is interpreted as still in progress. This can be a mess for what I'm trying to do and I don't use drag & drop. Is there a way to disable this?

I was in the process of updating my ubuntu desktop version 24.04. A message displayed saying "waiting for unattended update". I would like to know what that means. Will it affect my ability to install updates in the future.

I installed DaVinci Resolve and been having some issues with it. In Fusion tab, if I press CTRL key in my keyboard the program closes instantly. How do I discover why this is happening?

I have the hardware to run it and it will be working fine as long as I don't press the CTRL key, that's very odd to me. I need help to understand the core of the issue and solve it.

Obs.: I do not want to report a bug to Blackmagic, I just need to run the software to work.

Thank you in advance.

I'm having trouble with my Ubuntu 22.04.5 LTS virtual machine not accepting TCP connections.

I installed monit and configured the httpd to work on all IPs on TCP 2812. I can connect to the port with netcat when run on the local host but not from remote host. The connection times out. I disabled ufw (ufw disable) without effect.

The Ubuntu server and the host from which I'm testing are in Azure, on the same vnet (same IP network). I updated the network security group to permit TCP 2812 to all hosts, even though that's not necessary for this to work (hosts are on the same vnet). I can connect to the Ubuntu server via SSH and TCP 80 and TCP 443.

To rule out the monit process being the problem, I shutdown monit and configured netcat to listen on 2812 (nc -l -p 2812). After confirming that the server was listening on the port, I tried to connect from the remote host. The connection timed out. I was able to connect from another shell session on the Ubuntu server (using netcat).

To see if the problem is specific to my Ubuntu server or to the Azure vnet, I configured a Debian VM on the same vnet to listen on TCP 2812 using netcat. I can connect to that server on that port from multiple hosts on the vnet.

Something else I've noted is that even with ufw disabled, my Ubuntu server doesn't respond to pings from hosts on the local network.

The Ubuntu server is behaving as though there's a firewall blocking connections even though ufw is disabled.

I'm stumped as to what could be the problem.

I've read some pdf documents throughout a long period of time and I'd like to backup the last known position where I stopped reading/last read page of each document.

I hope I'm explaining my self properly. Another way to put it is that I'd like to back up the data that saves my last read page on a series of pdf documents .

Every time I open a pdf that I read previously my system opens the last known page . Is it possible to back up such data ? It must be saved somewhere as it is accessible every time I open a old read pdf .

My terminal is not opening at all so i have installed warp for it but i am facing issue in it

Description:

I’m unable to boot Ubuntu Server after migrating the system from an HDD to an SSD on an ARM-based system. Here’s what I did and the current state:

Steps to reproduce:

1. I cloned the EFI partition from my original HDD (/dev/sdc1) to a new SSD (/dev/sde1) using mount and cp (or another cloning tool). Both partitions are 500 GB.
2. Set the SSD as the boot drive in UEFI/BIOS as the first priority.

Current behavior:

When booting, GNU GRUB (version 2.12) only shows one option:

*UEFI Firmware Settings

No Ubuntu boot entry appears, and I cannot proceed to the OS.

Seeing only "UEFI Firmware Settings" in GRUB usually means GRUB isn't detecting your Linux kernel or other OS entries, often due to incorrect EFI System Partition (ESP) mounting, missing kernel modules, issues during installation, or disabled OS Prober, requiring steps like reinstalling GRUB with correct partition mounts (e.g., ESP to /boot or /boot/efi), enabling os-prober, disabling Windows Fast Startup, or running efibootmgr to manually create entries.

What I’ve tried:

1. Checked that the EFI partition on the SSD contains a /boot/efi/EFI folder.

   userA@ubuntu:~$ sudo ls -al /boot/efi
   total 24
   drwx------ 3 root root 16384 Jan  1  1970 .
   drwxr-xr-x 1 root root   120 Dec 10 17:17 ..
   drwx------ 4 root root  8192 Dec 17  2018 EFI
   

2. Try to use Boot Repair to fix the problem but got error message:

   64bits detected. Please use this software in a 64bits session. (Please use Boot-Repair-Disk-64bit (www.sourceforge.net/p/boot-repair-cd) which contains a 64-bits-compatible version of this software.) This will enable this feature.

3. Try to re-generate the GRUB configuration file.

   # Regenerate the GRUB configuration file
   grub-mkconfig -o /boot/grub/grub.cfg
   
   # Reinstall GRUB for UEFI systems
   grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=GRUB
   

   But got error:

   grub-install: error: /usr/lib/grub/aarch64-efi/modinfo.sh doesn't exist. Please specify --target or --directory.
   

System information:

• Architecture: ARM (Marvell® ThunderX2® CN9975 28-core ARM processors)
• Original HDD: /dev/sdc1 (EFI partition)
• Target SSD: /dev/sde1 (cloned EFI partition)
• Ubuntu version: 24.04.3 LTS

How can I rebuild the GRUB boot entries or fix the boot configuration from a USB live Ubuntu desktop environment?

I have installed Xubuntu v25.10 on a old Chromebook.

It seems to be working fine however if I open the App Center app there is screen tearing happening.

It flickers between normal and scrambled.

I have no problems with other apps I have tried. I have used Xfce Terminal, Firefox and LibreOffice Writer so far.

If I run lspci -k | grep -EA3 'VGA|3D|Display' I get the following:

00:02.0 VGA compatible controller: Intel Corporation Atom/Celeron/Pentium Processor x5-E8000/J3xxx/N3xxx Integrated Graphics Controller (rev 35)
   DeviceName: VGA compatible controller
   Subsystem: Intel Corporation Device 7270
   Kernel driver in use: i915
   Kernel modules: i915

I am not a Linux user so I don't know where to start to fix the problem.

I tried the following from the https://www.reddit.com/r/Ubuntu/comments/1cfzjpj/screen_flickering_in_ubuntu_2404/ thread but Xubuntu was no longer booting into the graphical environment so I had to delete the created file:

sudo gedit /usr/share/X11/xorg.conf.d/20-intel_flicker_fix.conf 

Created these lines in the file:

Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "TripleBuffer" "true"
Option "TearFree" "true"
EndSection 

I have now tried all the programs installed on Xubuntu and the screen tearing is happening on 2 apps; App Center and Firmware Updater.

I ended up just booting from a USB & reinstalling, which is really annoying but it's fine I guess since I need my laptop to finish out the semester. I'd still like to know what went wrong if possible in case it reoccurs

Apologies in advance for poor formatting. I have to do this on my phone because I'm locked out on my laptop & it's infuriating.

I installed a few apps (GIMP, Inkscape, Krita, Gnome Tweaks) then my laptop locked from idle time while I was waiting for a few updates. When I went to log in again it gave me "Authentication Error" when just clicking on the password entry box. I attempted to restart to fix the issue (There was no option to do a normal shut down so I suppose this would be considered an unclean shutdown) & this is what I was left with

I've tried running the command sudo systemctl start graphical.target to no avail, it simply moves me to another line as if to enter another command

Why am I stuck on this screen? It's like a full screen terminal & nothing else is showing. I've tried everything I can think of & it keeps saying it's wrong.

Do I need to reinstall Ubuntu? What is the problem?

Yesterday I installed a new GPU the Radeon RX 9070XT Tiachi. My system won't recognize the card.

Steps I have taken:

Motherboard MSI PRO B850-P wifi, updated BIOS:

latest version: AMI BIOS 7E56v2A75 2025-09-10

Updated my kernel from 6.17 to 6.18.0-061800-generic (Ubuntu 25.10)

also updated to Mesa 25.3.1

Uninstalled the AMD GPU stack and reinstalled the latest version:

dpkg -l | grep amdgpu

ii amdgpu-install 30.20.1.0.30200100-2255209.24.04 all AMDGPU driver repository and installer

ii libdrm-amdgpu1:amd64 2.4.125-1ubuntu0.1 amd64 Userspace interface to amdgpu-specific kernel DRM services -- runtime

ii libdrm-amdgpu1:i386 2.4.125-1ubuntu0.1 i386 Userspace interface to amdgpu-specific kernel DRM services -- runtime

Currently I have my HDMI plugged into the motherboard (R7 7700 cpu) so that I can see, because when I connect the DP to the GPU my screen stays black.

I am curious about this bit, 512MB is from the integrated graphics, but the 16GB should be my new card?

I've been scouring the internet for a couple of hours trying to find a solution, but so far anything I've tried hasn't worked.

I hope someone can help me out with figuring this out, thanks in advance.

I recently installed Ubuntu 24.03.3 LTS on a new bought Lenovo IdeaPad 5 2-in-1 14IAL10, alongside Windows 11. Everything worked fine (except the Realtek sound card, but that's another issue) until after two days the bootloader didn't show up anymore. It's not listed in the bios either. The only option there is the Windows bootloader. I can still log in the Windows 11 partition, but not anymore into Ubuntu. With an Ubuntu live edition I downloaded "Boot repair" and got the following report:

Does anybody have an idea what to do? Thanks for input on the issue.

In October I migrated from Windows 10 to Ubuntu, rather than suffer Windows 11. It has been going well, but I am getting this problem when Ubuntu Discover tries to do a firmware update:

Ubuntu Discover update "failed to write-firmware: failed to write (null): failed to write data to efivarsfs: Error writing to file descriptor: Invalid argument"

Even more irritating, I dismiss the error message and it pops right back. The Discover updater captures the cursor too quickly to close the program, leaving me stuck. The cursor/mouse is captured by Discover, leaving me unable to do anything other than close the error message box, which pops right back endlessly.

The first time this happened, I tried the reset button on the PC, but that had the bad side effect of leaving a couple drives with "missing mount points", which I had to remove from the PC and put in my old Windows 10 PC and run partition manager to scan them for errors, then back in to my main PC and all was happy again. Yes, I know there is a way to do this in Ubuntu, but I felt too newbie to try it and risk losing important data. And yes, I do have a back up, but some recent things might have been lost.

The second time this happened, just this morning, I was able to click on the Discover icon on the left of the Task Manager bar and manage to quit Discover after several tries. A quick right click on the icon and then a typed Q to quit, if done quickly enough was able to do the job.

failed to write-firmware: failed to write (null): failed to write data to efivarsfs: Error writing to file descriptor: Invalid argument

Since I upgraded to Ubuntu 25.10, once I connected my Bluetooth headphones, it just keeps making the hardware connect/disconnect sounds repeatedly.

I checked dmesg, journalctl, etc - no unusual activity, nothing connecting or disconnecting.

Any idea what could be happening? The only "solution" I've found is to turn off system sounds altogether.

Last year I bought a Dell G15 5530. It came with Ubuntu 22 LTS. I decided to change OS to Ubuntu 24, and it worked perfectly for a year until recently.

After an update I lost wifi access: after boot my wifi connected for a minute, then stopped working. Turning off and on the wifi from the applet resulted in two behaviours:

• the wifi adapter not being able to detect networks;
• no wifi adapter found.

I am on slow USB tethering since the update in mid september.

I tried to solve the issue looking for my problem here, then using chatGPT. Summarizing more than a month of tribulation, I tried to:

• update the kernel from generic 6.8 to HWE (6.14)
• reinstall the singular required modules from web.git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/intel/iwlwifi/
• restart after powering off for 30 seconds the machine.
• boot a clean ubuntu 24 from a usb

Lastly, I present a sequence of commands after which I fixed the issue for a week:

1. change updates' source to https://archive.ubuntu.com/ubuntu and reinstall the firmware (I was using the US source with http)
2. sudo apt-get clean
3. sudo rm -rf /var/lib/apt/lists/*
4. sudo apt-get -o Acquire::ForceIPv4=true -o Acquire::Retries=3 update
5. sudo apt-get upgrade
6. sudo apt-get clean
7. sudo apt autoremove
8. wget http://ftp.usf.edu/pub/ubuntu/pool/main/l/linux-firmware/linux-firmware_20240318.git3b128b60-0ubuntu2.17_amd64.deb
9. sudo dpkg -i linux-firmware_20240318.git3b128b60-0ubuntu2.17_amd64.deb
10. sudo reboot now sudo apt-get clean

wget http://ftp.usf.edu/pub/ubuntu/pool/main/l/linux-firmware/linux-firmware_20240318.git3b128b60-0ubuntu2.17_amd64.deb && sudo dpkg -i linux-firmware_20240318.git3b128b60-0ubuntu2.17_amd64.deb

For a week, and I thought the problem was solved. Hours after another update (which did not contain firmware updates), while using bluetooth headphones to watch a streamed movie, the bluetooth disconnected, then the wifi went down, and the issue came back.

The file linux-firmware_20240318.git3b128b60-0ubuntu2.17_amd64.deb is not hosted anymore on the source I used.
Running again sudo dpkg -i linux-firmware_20240318.git3b128b60-0ubuntu2.17_amd64.deb results in the wifi applet to display, and work for a minute.
Running sudo dpkg -i linux-firmware_20240318.git3b128b60-0ubuntu2.19_amd64.deb results in the wifi applet to disappear, sometimes alongside the bluetooth one.

Booting from a ubuntu 22 usb results in wifi working, but I would prefer to keep this os.

To get a full report of my system I disconnected the Tethering USB, and ran wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && chmod +x wireless-info && sudo ./wireless-info

I posted the results here: https://paste.ubuntu.com/p/JP5qshCDmF/

Update: after running sudo dpkg -i linux-firmware_20240318.git3b128b60-0ubuntu2.17_amd64.deb, reboot, disconnecting power source and flea power reset, it seems that I have working wifi, as long as I don't turn on bluetooth and do not update to the 2.19 firmware.
How do I proceed? from now?

Update: I turned on the pc, and in the matter of minutes the wifi was gone again: first troubles finding networks, then the applet disappeared.
I tried to update again (to 2.19), and reboot + flea power reset. For now I have wifi again, but this process takes more than an hour to fix every time, and the fix is not guaranteed to last.

I have the issue that ubuntu 24.10 is no longer receiving security updates but cannot upgrade to 25.04 due to me having ZFS on my filesystem. When i try to update my computer i get the error:

"Sorry, cannot upgrade this system to 25.04 right now System freezes have been observed on upgrades to 25.04 with ZFS 
enabled. Please see https://wiki.ubuntu.com/PluckyPuffin/ReleaseNotes for more 
information. "

I do not know what to do as the only way for me to have both ZFS and security upgrades would be to reinstall 24.04, which would make me lose all of my data and also access to wayland.

My question is:

What do i do to not reinstall the system while also not being on an unsuportted version?

I want to install microsoft teams for Ubuntu 22.04 LTS so I can join a video conference. Unfortanetly, I am getting a 404 from the deb download page. I don't want to install the unofficial client from snap for security concerns. Does anyone have this working?

The error message is as follows:

pci_pm_suspend(): nv_pmops_suspend+0x0/0x30 [nvidia] returns -5
dpm_run_callback(): pci_pm_suspend+0x0/0x190 returns -5
nvidia 0000:01:00.0: PM: failed to suspend async: error -5

I have tried the steps outlined here https://ask.fedoraproject.org/t/laptop-unable-to-suspend/16290/14 but this seems to be a solution for fedora and my system does not seem to contain nvidia-suspend.service in that location

I also completely ripped my computer of my nvidia driver and reinstalled driver from scratch to no success

Does anyone have advice on getting Nvidia to suspend properly?

From couple of days I have the latest Ubuntu 22.04 and I'm very happy - but first time I have issues with my bt mouse (Logitech MX Master) When I connect my mouse via bluetooth and set pointer speed and flat type - everything is fine, but everytime when I disconnect mouse and reconnect I loose mouse settings and have to set pointer speed manually. I'm using KDE and have a question - why after reconnect my mouse Ubuntu don't launch saved mouse configuration ? I tried even set configuration with xinput but with no effect. Is is possible to install some alternative app for ubuntu which will control my mouse settings ?

Hi first of all i'm a first time user and a newbs in this computer thing.

So i try to install linux on my windows laptop and it gave the eror:

TSC_DEADLINE disabled due to Errata; please update microcode to version: 0x22 (or later)*  
couldn't get size: 0x0000000000000e

My laptop is Asus X450J:

Intel® Core™ i7 4700HQ Processor,

Intel® HM86 Express Chipset

8GB DDR3L 1600 MHz SDRAM, up to 16 G

NVIDIA® GeForce® GT 745M 2GB DDR3

​

I have updated my bios in the asus website:

https://www.asus.com/Laptops/X450JF/HelpDesk_BIOS/

and also try the solution from:

https://www.reddit.com/r/Ubuntu/comments/92uxbf/unable_to_install_ubuntu_firmware_bug_tsc_deadline/

​

yet nothing works, any suggestion?

Edited: First thank you for the input.

1. Are you booting off of a CD? A USB? How did you create the USB?

USB, i created with Rufus 3.6 bootable from ISO file

2.When does this error occur? What solution did you try from the redit thread?

it happened when I try to install ubuntu or try ubuntu everytime. the solution i try from reddit is this:

• Boot the usb and press arrow down for "install ubuntu"
• Press "E"
• go down to the linux line and press END-key
• write ACPI=off nomodeset
• press F10 to restart

But nothing changes

3. Are you first booting into the "try Ubuntu" and installing from there or are choosing "install Ubuntu" from the menu that appears when you boot?

I tried all of the methods: a. "try Ubuntu" resulted in same error. b. install ubuntu also resulted in same eror

When I wait out the process (after screen showing TSC_DEADLINE disabled due to Errata....) lots of programming line seems flashing really fast after that it enters a screen with ubuntu and loading dots but after that nothing happen.

The installation is done with USB. I also tried with Linux mint but the results remain the same. I also try to redownload the installation from the website and redo the process but nothing changes.

I want to restart the network service in Ubuntu 18.04. I tried /etc/init.d/networking restart but the command didn't come out as expected. Can someone help resolve my issue?

When i try to install apps from Ubuntu software center it's showing the error Unsupported proxy configured. Proxy in terminal and browser is working fine.

I’ve been having problems with Seahorse lately. I suspect an update, but can’t say exactly when it started. It may also be two co-incidental problems.

In Thunderbird I use the Enigmail add-on to sign messages using PGP key. When you type in the passphrase there is an option to have it remembered (presumably by Seahorse), but this doesn’t work any more. Every session it asks for the passphrase again.

In Nemo (or Nautilus) if I do an adhoc connection to a SMB share and choose an option to remember the password, it is not saved.

If I run Seahorse (Passwords and Keys) there is no Passwords section, only Certificates, PGP Keys and Secure Shell. On the other 16.04 system I have, there is a Passwords section and the keys are in ~/.gnome2/keyrings/. On this computer (upgraded from 14.04) the keys are in ~/.local/share/keyrings/ and there is no ~/.gnome2/keyrings/ folder. I see references to both, but which is right?

Also if I choose to create a new item in the GUI, the options for creating a new Password Keyring or Stored Password (which are available on the clean install) are missing.

• Windows 10 Pro with Hyper-V enabled.
• Latest Ubuntu 16.10 x64 server iso.
• Created a new Hyper-V vm with defaults, 20GB vhd, 2 cpu's, 2GB memory, virtual switch, mounted the iso and started install.
• VM is Gen 2. I disabled Secure Boot in the firmware settings, read a number of articles that by doing so Gen2 was supported in Linux and esp in Ubuntu.
• It was able to access the internet and downloaded packages while installing.
• Chose all defaults, let LVM partition disk, let it install GRUB, again with all defaults.

But when I start the VM I get a screen saying no OS can be found. Please help.

Whenever I try to watch a video with VLC media player and try to watch it full screen, the size of the video stays the same, and the rest of the screen is filled with the color blue. This happened for both 480p as well as for 720p videos. I already installed ubuntu-restricted-extras.

What other packages/codecs do I need to install to be able to watch videos?

I'm attempting to run a script which calls service dnsmasq restart

service dnsmasq restart
dnsmasq: unrecognized service

No matter what I call for dnsmasq, it gives me the "unrecognized service" error.

Also if I type dnsmasq restart I get

dnsmasq restart
dnsmasq: junk found in command line

I have tried autoremoving and reinstalling dnsmasq. I've googled both responses, and not finding any fixes. Can anyone help?

Thanks!

I downloaded some themes from gnome-look.org and I extracted and put them in /usr/share/themes folder and when I opened gnome-tweak-tool windows theme was working but GTK+ themes section was showing only the default ones. Then I put the themes into ~/.themes folder but still no luck. How can I fix this?

For example, one of the themes is this one:

http://gnome-look.org/content/show.php/absolute?content=126326

I have a six year old little sister. She gets online. My parents want her on a kid safe browser like Zoodles.

Are there any for Linux? Is it possible to install Zoodles on Linux? All the ones I've found download the install stuff for windows.

Also. I'm brand new to Linux, so instructions on how to would be much appreciated. =3

I have Ubuntu 12.10, Just in case that matters.

How can I use Qwerty hotkeys with the Dvorak keyboard layout? For example I want C to map to J, but Ctrl + C to remain as Ctrl + C.

The dvorak-qwerty program is supposed to do this, but does not work for me.

Desired behaviour seems to occur in the terminal and with foreign language layouts.
