I'm having trouble setting up Remote Desktop in Ubuntu 26.04. After starting Remote Desktop on port 3389 and entering my username and password, the remote desktop session launches (I want to keep the same session open at all times). After restarting the computer, I can’t connect to it remotely. I have to log into Remote Desktop locally again and unlock the settings by entering the root password. Is there a solution so that this also works after a restart?

I have a ASUS TUF GAMING laptop with two separate nvme each 1TB. On first one windows 11 installed with bitlocker disabled. And on the second one I installed Ubuntu Raccoon. But during installation Ubuntu installer reported bitlocker detected. Anyhow installation finished without any problem. I did not used any encryption also. Just created a user to login. I have created a swap, efi and an ext4 partition. After login, I could not mount the ext4 partition as it prompts for a password!? By the way, I checked the disk and discovered a Microsoft reserved partition in front of queue which was strange. Any idea? Tks

i've upgraded to Ubuntu 26.04 LTS - now it won't accept my old password at startup. how do i fix?

Also, instead of giving me normal login ui, i get tiny little text prompts in top left corner.

I've a Surface Pro 6

I have multiple users with thumbnail and these are shown in login screen. For the administrator which was created during install it is set as well, but NOT showing in login. Privileges are fine (or at least the same as other).

Can someone advice why it's not shown?

I recently upgraded to Ubuntu 26.04 LTS, and I noticed a new icon on the Dash. It's in the system area. There's the WiFi icon, sound, the new icon that looks like a speedometer, and the battery. When I click on the speedometer I get the usual list of things, but there's no longer a speedometer.

What is this icon and what is it for?

Back in the 90s I remember being amazed at the 'dancing postage stamp' videos of the time. I now know that many of these dancing stamps were Cinepak videos. Can I use a modern FFmpeg under Ubuntu to recreate one of these early movies and make it as authentically '90s' as possible?

I made a list on the bash with all the packages installed on Ubuntu.

Trying to restore them to another computer also with Ubuntu, I receive an error message saying that they are not on database.

With this command I made the list:

dpkg --get-selections > list_packages.txt

Then I imported the selection list to the package manager with this command:

sudo dpkg --set-selections < list_packages.txt

Finally, I tried to install the packages with this command:

sudo apt-get dselect-upgrade

There, the message says: packages not in database.

Trying to install them on dissimilar hardware with the same Operating System, I acknowledge the solution.

I had TOR Browser installed and it worked perfectly, until today when it refused to open. I uninstalled then installed it again and got this when I tried to open it:

ldconfig failed, exit status 256

I have received this message with with other software I installed as well. I'm not sure what any of this means. It is taking me time to reacquaint myself with Ubuntu, and I pretty much have to start from scratch each time I load it.

I booted up Ubuntu server to start my home lab, but when I try to connect to WiFi in the first boot thing, it gives me “scan failed: error triggering scan failed -100”. I’m using a TP-link AC600 Nano wireless Archer T2U Nano WiFi adapter.

I attempted to change my dual boot (Windows 11 / Ubuntu 20.04) Lenovo x1 Carbon 8th gen into a Ubuntu 24.04 only environment. After downloading the iso, etc. and choosing a full overwrite, I "successfully" installed Ubuntu 24.04 from a USB drive, but now I can't boot into either Windows 11 (as expected) or any Ubuntu distro.

The boot choices I am given in the boot menu are 4: Ubuntu, Windows, Pxe, and a hard drive. None of the choices boot into anything. All I get is a return to the same 4 useless choices. I want to make the laptop boot into Ubuntu 24.04 only. How can I do that?

I'm trying to change the cursor sensitivity on the login screen, however none of the approaches I could find online seem to work in Ubuntu 26.04. I am using the default setup with Wayland and GDM.

So far, I've tried using dconf as suggested by some article online (sudo -u gdm dbus-run-session dconf write /org/gnome/desktop/peripherals/mouse/speed -0.8), however this fails and returns...

unable to create directory '/var/lib/gdm3/.cache/dconf': Access denied.  dconf will not work properly.

Another approach that I could find was using sudo -u gdm dbus-launch gsettings set org.gnome.settings-daemon.plugins.mouse active true, however dbus-launch does not exist in my case.

Can somebody direct me to a method that works on recent versions? I'm quite new to Ubuntu and Linux in general and don't really know my way around. Thank you.

Trying to boot an old computer using a live USB and from qemu I see:

However, the Ventoy thumb drive just hangs. I don't have another system to check the thumb drive on, unfortunately.

Using:

sudo qemu-system-x86_64   -m 2048   -enable-kvm   -bios /usr/share/OVMF/OVMF_CODE.fd   -drive format=raw,file=/dev/sdb

which seems to work insofar as it shows a boot screen. The boot option does show. However, it just hangs for fifteen plus minutes.

I was playing in Firefox "forge of empires" when I believe I saw an error note about NVIDIA. I closed all software and did a restart ... to no avail.

@heynnema ls -al /boot screenshot

The computer is booting, all looks fine, but I receive at bootscreen now the error (translated):

forbidden by the secure boot guideline. Loading Linux 6.17.0-23-generic ... Loading initial ramdisk ...

@heynnema this is not easy for me ... I work on your recommendations!

@heynnema nvidia seems to be installed, but there have been error messages, unfortunately in German, which I translated to the best of my capacities:

dpkg: error working at the package nvidia-driver-535 (--configure): dependency problem - it remains not configured
Trigger für libc-bin (2.39-0ubuntu8.7) are worked at ...

linux-modules-nvidia-535-generic-hwe-24.04
nvidia-driver-535
E: Sub-process /usr/bin/dpkg returned an error code (1)

I don't know how to reboot back to the 29 kernel, because now the "Advanced..." option is missing, when hitting F8 at booting (perhaps because Ubuntu is loading "initial ramdisk"?)

@ maybe here is already something wrong?

I just upgraded to 26.04, and all looks good, but "youtube" glitches repeating black screen and then displays video resolution. The video continues until the next black screen about 1-2 minutes later.

Firefox loads other webpages OK.

Any help would be helpful as I am sensitive to flickering lights.

I’m on Kubuntu 26.04 with KDE Plasma 6 and I’m having issues with color emoji rendering. Some emojis appear monochrome, render just fine

Chrome screenshot1 Example broken plage chatgpt

These are my command history I ran before the issue started:

sudo apt reinstall fonts-noto-color-emoji
sudo apt reinstall fonts-noto fonts-noto-core fonts-noto-ui-core
sudo apt remove fonts-twemoji-svginot

fc-cache -f -v
rm -rf ~/.cache/fontconfig
rm -rf ~/.cache/fonts

nano ~/.config/fontconfig/conf.d/01-emoji.conf
sudo nano /etc/fonts/local.conf
cat /etc/fonts/local.conf

shopt -s dotglob; mkdir -p ~/.fonts/truetype/noto; ln -s /usr/share/fonts/truetype/noto/* ~/.fonts/truetype/noto
rm -rf ~/.fonts/truetype/noto

fc-match emoji

If needed, I can also share the contents of 01-emoji.conf and /etc/fonts/local.conf.

What is the correct way to restore color emoji support on KDE6 / Kubuntu 26.04?

I've been encountering plenty of problems in Kubuntu 26.04 that won't let me use my PC normally:

1. Translucently and wobble window effects get reapplied after each reboot without my consent.

2. Chrome on xorg with using the built-in classic option from appearance aka colors, the title bar buttons disappear when I try to type on the address bar.

3. Plymouth animation appears during transition from sddm to desktop (I have selected None as a transition).

4. The locale on the time widget in taskbar rejects any effort to be changed and still uses the Greek time format ΠΜ, ΜΜ, When I clearly set it to American am pm. I use Greek only for the keyboard.

I have to note that I also use klassy. I seriously need to find a solution because the name implies LTS and I am disappointed.

I am using plasma 6.6.4. just upgraded.

I have HP Envy x360 convertible 15-ds1063cl, AMD Ryzen 5 4500U, Intel NVMe, Micron 8GB RAM. 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, the OS gets stuck on grub or a black screen. I have to remove my USB mouse (Logitech G502 hero or Fantech x17 blake) to boot to the OS.

I tried every solution I could find on the internet, but none of them worked. I tried different USB ports, disabled TPM, Secure Boot, USB boot and virtualization, but I had no luck. My BIOS is up to date. When I remove the mouse and connect any USB device, like an external HD or a USB flash drive, then it works fine without issues, but Ubuntu and Fedora don't like my mice.

Notebook model HUAWEI BoDE-WXX9, which is according to google a part of matebook D14 or D15 Bought it in 2025. Do not know the year of manufacture. SN is rlnpm23913000943

May 15, 2026 Upgraded to 26.04 with the same result. No sound and camera

Just upgraded my ubuntu 25.04 to 25.10 hoping that the problem with the sound and camera would be resolved. But sadly it's still the same.

My laptop is a brand new laptop Huawei BoDE-WXX9. However the sound and camera are not working. How to resolve this? Attached the images of the specifics and sound settings. Thanks in advance for any assistance

I have Ubuntu 24.04.1 LTS on a Dell XPS 9320 (not dual-boot). Since I upgraded from 22.04 last month, my internal speakers have not worked. In Settings, Sound Output lists "No Output Devices". I do get sound via USB devices (speakers or earbuds). I've tried many suggestions from many related questions (see below), but none have worked. Now I'm reaching out for help (please and thank you). From my reading of the related questions, here's relevant information for my case.

Based on remarks of V1del, a forum moderator at archlinux. I tried the following 4 commands to diagnose:

$ sudo fuser -v /dev/snd/*

                 USER        PID ACCESS COMMAND
/dev/snd/controlC0:  jim        2555 F.... wireplumber

I guess the two "Connection failure" are a problem, but I don't know what they mean.

Based on my research the past few weeks, the following also seem relevant to diagnosing my problem.

$ lspci | grep -i audio

I don't see a sound problem in that output (the Device-1 line makes sense, as my camera doesn't work (Cheese, Skype); but that is not my focus here). I do see a problem from the next command I tried

$ sudo dmesg | grep -i snd

When I google "SDW0-Capture: ASoC: error at snd_soc_link_prepare on SDW0-Capture: -61" I see many posts (often Archlinux) that talk about downgrading the kernel. I don't know what that is, and it sounds bad (like a duct-tape fix, a patch not a fix). But maybe useful to note my kernel:

$ uname -r

Please note that pipewire seems fine:

Thank you in advance to any kind soul who can help me restore my speaker sound. And I'd be happy to share more info if it would help ...

PS If it helps, here is a sampling I other questions I've looked at for help:

Fixing No Sound (Dummy Output) Issue in Ubuntu 24.04 From the top answer there, I used sudo gedit to create /etc/modprobe.d/audiofix.conf and put in the lines

options snd-hda-intel dmic_detect=0
options snd-hda-intel model=laptop-amic enable=yes

After rebooting, no change.

No sound output devices listed after upgrade from 21.10 to 22.04 looks relevant, but it is about pulseaudio and 24.04 uses pipewire.

Fixing No Sound (Dummy Output) Issue in Ubuntu 24.04 suggests to downgrade the kernel, but that sounds bad to me. And my sound problem is "No Output Devices", not "Dummy Output"

I see several unanswered questions that may be about the same as mine, with no speaker-sound in 24.04; e.g. lenovo M90a, Ubuntu 24.04, missing sound on speakers, earphones ok

In my case aplay lists a sound card, so my problem differs from many other dealing with no sound in 24.04, such as No sound after upgrade from Ubuntu 22.04 to Ubuntu 24.04.

No sound in internal Speakers in Ubuntu 24.04 sounded promising, but the fix there was to disable fast-boot in Windows (I don't have Windows).

=== Here's more info,

 tail "/etc/modprobe.d/alsa-base.conf"
    options snd-usb-usx2y index=-2
    # Ubuntu #62691, enable MPU for snd-cmipci
    options snd-cmipci mpu_port=0x330 fm_port=0x388
    # Keep snd-pcsp from being loaded as first soundcard
    options snd-pcsp index=-2
    # Keep snd-usb-audio from beeing loaded as first soundcard
    options snd-usb-audio index=-2
    # options snd-hda-intel model=auto -- tried & failed for audio 
     fix 27Oct2024
    # blacklist snd_soc_avs
    options snd-hda-intel model=dell-headset-multi

As suggested by heynnema, here are two more pieces of info

I updated my bios to the most recent (from 2.10 to 2.16.1) but that seems not to have affected anything.

video card seems to be Intel

As suggested by @hynnema, I used Mainline to change kernels to 6.5.11 and added "options snd-hda-intel model=dell-headset-multi" to alsabase.conf and rebooted (kernel 6.5.11) but still No Output Devices in Sound Settings. But now pipewire has a problem:

I plan use Dell's system restore, but first I need to back up my data and my legacy software programs.

I am trying to install Freetube in Ubuntu 22.04 armhf (Raspberry Pi image) running in a Surface RT.

Freetube only provides .deb files for amd64 and arm64 architectures. Flatpak stopped supporting armhf, and the armhf version of Freetube available on Flatpak is outdated (it does not load Youtube videos anymore, probably due to change of API).

Is there any way to install Freetube on armhf Ubuntu? How can I compile (or preferably cross-compile) Freetube?

The height of title bar in GNOME is really wide. Is there a way to make it narrow without installing any extension or theme? Title bar of File manager and Terminal is wide and looks ugly. I love how narrow the title bar of Unity on Ubuntu was. I'm on Ubuntu 20.04 GNOME: 3.36.8

I have an XPS13 with an Ubuntu 18.04.1 LTS running on it. It has a Intel Corporation HD Graphics 5500 integrated graphical card. Everything was fine till the last reboot (before the reboot I have installed some Latex related packages). My display manager now shows only one resolution available:

Additionally, when I plug-in the external display nothing happens. Just before the reboot everything was working perfectly.

The output from xrandr looks as follows:

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 3200 x 1800, current 3200 x 1800, maximum 3200 x 1800
default connected primary 3200x1800+0+0 0mm x 0mm
   3200x1800     90.00* 

and from sudo lspci | grep -i vga

00:02.0 VGA compatible controller: Intel Corporation HD Graphics 5500 (rev 09)

Does anyone knows any way to fix that issue?

I was making mnt directory in home-directory and when I try delete it, I didn't realize my relative path was root(/). Eventually I deleted mnt directory in root... How can I restore /mnt? My file system is ext4.

Hi I have a toshiba satellite laptop. I recently decided to replace my os which used to be Windows 10 with ubuntu, and used a USB key to store the Linux installation, plugged it in, successfully installed Ubuntu and erased windows(as it says). After the installation A message popped up telling my restart the computer in order to Start using the new os. After doing so I get his blank screen With the message:

Reboot and select proper boot device Or insert boot media in selected boot device and press a key Can't access anything now, btw I did enter to BIOS and set everything back On default after the installation of the Linux and it still doesn't work Can anybody tell me what can I do?

I use ViberIndicator to start Viber with correctly display tray icon on Ubuntu 15.10. Then I added viberIndiator to startups applications Viber start with displaying last dialog window.

How to start Viber minimized on system startup ?

when I try to apt-get update I'm getting the below error,

E: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable)
E: Unable to lock directory /var/lib/apt/lists/

In tutorials and how-to's I often see commands combined. For instance,

sudo apt-get update && sudo apt-get install pyrenamer

There seem to be four possible connectors: &, &&, || and ;. Though the & connector is clear to me (it sends a process to the background and leaves the terminal available), it is not clear what the difference is between && and ;. And I did not know of || until Kaya's comment.

The following questions deal with the difference between the two connectors, but do so mostly in the comments:

• How to start two Ubuntu applications in one go?

• How to combine multiple commands in terminal?

So here are a number of related questions:

1. What is the difference between ; and &&?
2. When should you use them respectively? It would be nice to see some use cases: if I want to run a command and then after it shutdown my computer, which connector should I choose?
3. What are their advantages and dangers? Robie Basak mentions in a comment to this answer that a command like cd /somewhere_else; rm -Rf * can have destructive consequences if the first element in the command chain fails, for instance.
4. If relevant, where do they come from?

I have a game made with the LÖVE framework and I want to package it into a .deb file so it can be easily installed by others and be easily findable through the Unity dash for example.

I also have the LÖVE framework love_0.7.2.deb which I want to be in the deb file also somehow.

Files that I have:

game_icon.png
game .desktop
the_game.love
love_0.7.2.deb

Could someone explain to me how to do this?
