No signal from Displayport https://askubuntu.com/questions/1568193/no-signal-from-displayport

I am currently encountering an issue with my computer monitor link in Display-port.

My setup:

  • Ubuntu 24.04.4 LTS (64-bit)
  • NVIDIA 1080Ti
  • First monitor plugged with HDMI (no issues, work just fine)
  • Second monitor plugged with Display-port (detected, but not video signal). I can even move the mouse into the second monitor area.

It was working fine before I tried to connect it through a KVM dock.
This one: https://www.avaccess.com/products/idock-b23/

Since then, my monitor is no longer showing any signal, but is well detected:
My screen showing the displays connected, we can see that both screen are connected

I've tried:

  • Changed my cable.
  • Changed the monitor.
  • Unplugged and re-plug the monitor's power.
  • Update my NVIDIA's drivers
  • Visual check of the GPUs Display-port integrity (no apparent issues)

Does anyone have any idea how to fix this problem?

Unmounting hard drive (system drive) to check for errors https://askubuntu.com/questions/1568188/unmounting-hard-drive-system-drive-to-check-for-errors

Ubuntu 26.04 LTS. Desktop PC.

My PC suffered a sudden power loss a few days ago and now goes through a prolonged process before it finally allows booting in to the OS.

The display seems to be indicating errors caused the power loss. I want to check it for errors, but I'm told I need to unmount it first.

How do I unmount the drive where the OS is located? Will my PC still operate?

This is a bit of what the displays shows: enter image description here

Stylus pressure sensitivity not registering outside settings tab https://askubuntu.com/questions/1568187/stylus-pressure-sensitivity-not-registering-outside-settings-tab

New to the OS so excuse me if the solution is obvious. I have a Huion Tablet GT-156 model with official ubuntu compatible drivers installed, though for whatever reason my the device does not register pressure from the stylus on any software I've tested it on. It's puzzling because the only time I could get it to display strokes from the pen is on the Test Settings drop down in the ubuntu system settings tab; anywhere else the only thing that gets mapped is positioning of the stylus. Is it possible a system process is suppressing inputs?

Only place it works is here

Ubuntu 26.04 LTS Desktop

Laptop screen not responding upon opening https://askubuntu.com/questions/1568186/laptop-screen-not-responding-upon-opening

I have a Lenovo V15-ADA with Ubuntu 26.04 recently installed.

Upon closing the laptop, the screen locks as expected. When I reopen the laptop, the screen stays dark and I am forced to hard reset the computer.

This problem also occurs after the computer has been hibernating. Whether I move the mouse or press a key in attempt to turn the screen on, I get no response.

"The user name could not be found" error when connecting with Samba https://askubuntu.com/questions/1568180/the-user-name-could-not-be-found-error-when-connecting-with-samba

I have a Ubuntu server running in my home. Mostly for streaming movies and such but we just got a laptop for the kids and I was trying to set up samba so I can share files from my windows desktop to the laptop, but I'm running into a snag. When I attempt to connect to the share it asks me for my username and password but then I get a message that windows cannot access this network resource:

when I read log.aragorn (name of my desktop) I get

Broken desktop by using lxqt and then switching back to Ubuntu desktop https://askubuntu.com/questions/1568179/broken-desktop-by-using-lxqt-and-then-switching-back-to-ubuntu-desktop

Is version 26.04 beta? [closed] https://askubuntu.com/questions/1568176/is-version-26-04-beta

My homelab VM collapsed, it was on for a few years, so I thought I give a try to the new version.

It is nice, looks good, fast enough, lot programs, just the basic things don't work. You click on SSH allowance, it is on, until you click somewhere else, turnes automaticly off. Remote desktop never worked, screen sharing ask for authentication every second minute... If I just try to setup the system it asks for authentication every minute. And I am in the same vlan! It is far from the old reliable system, I was getting annoyed very fast, probably I put back the old version, if no repair update will arrive.

how long provides mozillateam (ppa) backports of firefox/thunderbird ESR for OLD Ubuntu versions? [closed] https://askubuntu.com/questions/1568171/how-long-provides-mozillateam-ppa-backports-of-firefox-thunderbird-esr-for-old

for many years I'm user of Ubuntu (only LTS) - with the mozillateam ppa added for firefox / thunderbird ESR usage; all running fine.

I would like to know:
--> Who knows a roadmap / timetable etc. of mozillateam relating to older versions of Ubuntu (desktop) ?
In other words:
--> How long does mozillateam make backports of older versions of firefox & thunderbird ESR for older versions of Ubuntu LTS ?

I'm family - cognation - neighbour & friends admin, ca. 20 PCs. All PCs on Ubuntu 24.04 LTS with mozillateam ppa from the start (installation), only FF/TB ESR versions installed - no "standard".
...but there are 2 or 3 PCs still running Ubuntu 20.04 LTS. And the owners won't change because "it is running fine - don't change ! ...". Auto update is still running: OS & software, and FF/TB are regularly updated (to 140ESR by now) - the only ones (& for longer).

No major security concerns: low internet usage - some surfing and emails. But thunderbird will be a problem: migration (of the mailboxes) to a new system is ugly when there are different versions running of old and new TB. Therefore I do need roadmaps of Ubuntu (and mozillateam) and Mozilla software.

Ubuntu 20.04 EOL was in 05/2025, and I know the Ubuntu release cycles too - as well as some of mozillas release hints.
mozillateam is the black box here. And I could not find any roadmap or similar on the web relating to old Ubuntu OS versions. Just relating to FF & TB (security updates until 1 year after release of successor...) - but no roadmap to the underlying OS versions.
Btw: Ubuntu Wiki (mozillateam) link is completely outdated; there are no valid contacts of mozillateam.

Thanks for any help
(and plz: no 'helpful' tips for customer communication / convince...) ;-)

I need some expert advice regarding Ubuntu and NTFS external/internal hard drives. Here is the full story of what happened: [duplicate] https://askubuntu.com/questions/1568170/i-need-some-expert-advice-regarding-ubuntu-and-ntfs-external-internal-hard-drive

I need some expert advice regarding Ubuntu and NTFS external/internal hard drives. Here is the full story of what happened:

The Setup & Version: I am using Ubuntu 26.04 LTS. I have an SSD and a separate Hard Drive full of important data. To keep my data safe, I disconnected the hard drive completely while installing Ubuntu on my SSD. After a successful installation, I reconnected the hard drive.

The First Issue: Once Ubuntu booted, it completely refused to mount my hard drive partitions. When I click on the partition in the file manager, a popup appears saying 'Error mounting... cannot mount'. After searching online and doing some manual tweaks using the Ubuntu 'Disks' app and the Terminal, I finally got the partitions to show up and open.

The Power Cut / Outage Issue: Shortly after fixing it, we had a sudden power outage, and the computer shut down abruptly. When the power came back and I booted into Ubuntu, the partitions were completely locked again. The same error popup came back, and I had to repeat the same tedious manual troubleshooting fixes via the Disks app and Terminal all over again.

The AI Advice: I asked an AI assistant for a permanent fix, and it suggested that I should format my NTFS partitions to ext4 because Linux handles its native format much better during power cuts. However, I have over 260GB of important data on this hard drive, so formatting is absolutely not an option for me right now.

Right now, I have temporarily moved back to Windows 10 because going through this manual process every single day after a power cut is very frustrating, but I really want to use Ubuntu as my main OS.

I get this pop up https://i.sstatic.net/XE3dUvcg.png

Long time screen issues https://askubuntu.com/questions/1568166/long-time-screen-issues

I have a Dell Latitude 3590 with Mesa Intel UHD Graphics 620 with VGA output.

The VGA is connected to a ViewSonic VA2446 External monitor.

   Built-in screen set to 1920×1080 (16:9)
   VA2446 is set to 1920×1080 (16:9)
   OS is Ubuntu Studio 24.04

The issue is the screen is too large for the displays, so the desktop will move to the edge (slide might be a better term) up and down, left or right. Even when the external is disconnected the Dell still does the same thing.

What am I missing here?

I cannot start Steam anymore in Ubuntu 26.04 [closed] https://askubuntu.com/questions/1568164/i-cannot-start-steam-anymore-in-ubuntu-26-04

I tried to run it from the terminal and received the following message.

Ubuntu 26.04 terminal font change https://askubuntu.com/questions/1568154/ubuntu-26-04-terminal-font-change

I am using Ubuntu 26.04 with the default GNOME desktop.

I want to change the font and font size in the Terminal, but I cannot find the Preferences option. Most tutorials say to open Terminal and go to Preferences, but that option does not exist in my installation.

I tried:

  • Checking the Terminal menu (top-right/hamburger menu).
  • Right-clicking inside the Terminal window.
  • Looking through the application settings.

None of these show a Preferences option.

Questions:

  1. Has the Terminal application changed in Ubuntu 26.04?
  2. How can I change the Terminal font and font size?
  3. If the Preferences menu was removed, what is the new way to configure the Terminal?

If needed, I can provide screenshots of the Terminal window and menu.

How to create a directory and change my working directory to the new directory? [duplicate] https://askubuntu.com/questions/1568151/how-to-create-a-directory-and-change-my-working-directory-to-the-new-directory

I am new to Ubuntu and have just installed it on my laptop. My first move is to install yWriter to port some of my projects. On the install page for Linux the instructions are to change your terminal location to a newly created folder containing yWriter, however I have only just opened a terminal window for the first time today and have no idea how to change it's present working directory.

edit: here is the guide on the yWriter website. https://www.spacejock.com/yWriter7_Linux.html as you can see, after the initial terminal commands the instructions are to "change your location to that folder", which is a bit too vague for a total noob like me. I tried a couple of cd commands but they all ended with location not found, and I didn't want to mess around too much for fear of doing something I couldn't undo. And I have winetricks installed and was able to copy and paste the first lines just fine

Error on updating packages in Ubuntu server after running sudo apt modernize-sources [duplicate] https://askubuntu.com/questions/1568118/error-on-updating-packages-in-ubuntu-server-after-running-sudo-apt-modernize-sou

So, what I did was run a command:

'> sudo apt modernize-sources`

The following files need modernizing:
  - /etc/apt/sources.list
  - /etc/apt/sources.list.d/mariadb.list
  - /etc/apt/sources.list.d/packages.cloudpanel.io.list

Modernizing will replace .list files with the new .sources format,
add Signed-By values where they can be determined automatically,
and save the old files into .list.bak files.

This command supports the 'signed-by' and 'trusted' options. If you
have specified other options inside [] brackets, please transfer them
manually to the output files; see sources.list(5) for a mapping.

For a simulation, respond N in the following prompt.

RAID6 disk overrwritten during boot by upgrade from Ubuntu 12 to 26 https://askubuntu.com/questions/1567988/raid6-disk-overrwritten-during-boot-by-upgrade-from-ubuntu-12-to-26

I have RAID6 disks running well on a old server running Ubuntu 12 with an old mdadm v3.2.5. That RAID is built directly on the disk, not into a partition.

I moved my 5 disks to my new server, with fresh install of Ubuntu 26.

When I boot my new server, the RAID is not created, and a partition is created on the 5 disks! I can not understand how Ubuntu can write to the disks without asking!

If a bring back the disk to my old server, it will not be created, but I can recreate it with the command

mdadm --create /dev/md125 --assume-clean --level=6 --raid-devices=5 /dev/sde /dev/sdd /dev/sdf /dev/sdc /dev/sdb

How can I prevent my new Ubuntu 26 from creating a partition on the 5 RAID disks. I just want UBUNTU to do nothing with them during boot. Than I could use mdadm to assemble, or create the RAID6.

I have played with grub to set to skip option to fsck, and it did not solve my problem. Something else is creating those partitions.

Here is what is created on my 5 RAID6 disks by something

Hibernation not working in HP 15 gr0012au https://askubuntu.com/questions/1567876/hibernation-not-working-in-hp-15-gr0012au

I am having a HP laptop with AMD ryzen 3 3250u processor and I installed ubuntu 26 LTS and I tried to add a hibernation device in the laptop using a swap file but what I am experiencing is that when I run the command sudo systemctl hibernate my screen goes blank for sometime and return back to the lockscreen, sometime it work for the first time and subsequent hibernate fails, I am pasting my configuration files

Ubuntu 26.04 installer freezes at Get:5 /cdrom resolute/main amd64 Packages on older Dell https://askubuntu.com/questions/1567178/ubuntu-26-04-installer-freezes-at-get5-cdrom-resolute-main-amd64-packages-on-o

I am trying to install Ubuntu onto an older Dell laptop using a freshly flashed and validated SanDisk USB 3.0 drive (flashed via balenaEtcher).

The boot sequence starts up fine, but it completely freezes every single time right after reading the very last APT cache repository line: Get:5 file:/cdrom resolute/main amd64 Packages [31.7 kB]

I tried:

  • Replaced the USB drive entirely (originally used a generic UDisk which threw I/O buffer errors, switched to a brand new SanDisk 16GB).

  • Removed quiet splash from the GRUB menu to view the verbose terminal logs.

  • Tried booting with nomodeset (Safe Graphics mode).

  • Tried appending various combinations of boot flags like acpi=off, noapic, and irqpoll.

The logs:

Right before it hits the Get:5 line and hangs, the logs show a couple of errors regarding the communication bus and filesystem:

fuse: device /dev/fuse not found. Kernel module not loaded?
dbus-daemon: A connection to the bus can't be made
Failed to create stream fd: No such file or directory

This is the terminal output right at the freezing point. Since it is stalling the exact millisecond it finishes loading the configuration files and tries to hand over control to the display manager/graphics, I suspect it's a legacy hardware or kernel conflict with this specific Dell motherboard architecture.

Do you have any advice on what specific kernel boot parameters or BIOS tweaks I need to use to force it past this graphical handshake?

Mic works on Windows but not in Ubuntu - ASUS Laptop https://askubuntu.com/questions/1566090/mic-works-on-windows-but-not-in-ubuntu-asus-laptop

I've been reading the forums and found quite a few people with a similar issue, but none of the solutions worked for me.

My internal microphone is not working on Ubuntu. It works fine on Windows (dual boot), so it's definitely a software/driver issue.

System info:

  • Computer: ASUS VivoBook X515EA
  • Ubuntu: 25.10 (Questing)
  • Audio chip: Realtek ALC256 (Intel Tiger Lake-LP Smart Sound)
  • Audio server: PipeWire 1.4.7

What I've tried:

  • Setting options snd-hda-intel model=asus-zenbook in /etc/modprobe.d/
  • Adjusting capture levels in alsamixer (F4 view, HDA Intel PCH card)
  • Setting the default source with pactl set-default-source
  • Reinstalling PipeWire and resetting WirePlumber config
  • Running amixer -c 0 cset numid=6 2 to select Internal Mic 1 (node 0x1b)

What I found:

  • arecord -D hw:0,0 with Internal Mic 1 selected (numid=6 set to 2) does show vumeter activity so ALSA can capture audio at the hardware level
  • However, PipeWire does not seem to pass the audio through, parecord and pw-record both record silence
  • The dmesg shows the driver picks up two internal mic nodes: Internal Mic=0x12 and Internal Mic=0x1b
  • Capture Switch (numid=8) needs to be set on,on manually after every reboot

arecord -l output:

List of CAPTURE Hardware Devices  
card 0: PCH \[HDA Intel PCH\], device 0: ALC256 Analog \[ALC256 Analog\]  
  Subdevices: 1/1  
  Subdevice #0: subdevice #0  

It seems like ALSA captures audio correctly when configured manually, but PipeWire/WirePlumber doesn't route it properly to applications. Any ideas on what could be causing this or how to fix it?

Second monitor not detected with HDMI, but well with HDMI to USB-C adapter https://askubuntu.com/questions/1559519/second-monitor-not-detected-with-hdmi-but-well-with-hdmi-to-usb-c-adapter

I am on a dual-boot (Ubuntu 24.04.03 LTS - Windows 10) configuration, and noticed that my second monitor stopped being detected via HDMI when on Ubuntu. Prior to my 24.04 upgrade (I was using 22.04), everything worked fine.

My setup is the following:

[HP E243i monitor's HDMI port]->[HDMI cable]->[laptop's HDMI port]

On Windows, it works fine. On Ubuntu, nothing is detected (the screen blinks when connecting to the computer, then goes back to sleep).

Running xrandr -q --verbose | rg -i HDMI outputs

HDMI-1 disconnected (normal left inverted right x axis y axis)

After trying X vs Wayland, upgrading the NVIDIA drivers to 535, 550 or 580 (recommended), nothing worked. Then, I tried to use an HDMI to USB-C adapter I have... and it worked!

[HP E243i monitor's HDMI port]->[HDMI cable]->[HMDI to USB-C adapter]->[laptop's USB-C port]

However, that's not really ideal for me and I'd like not to have to use the adapter.

Finally, it's probably worth mentioning that using the same HDMI cable, but with my TV, the following works...

[TV's HDMI port]->[HDMI cable]->[laptop's HDMI port]

Changing the HDMI cable doesn't seem to have any impact.

Does anyone have an idea of how to fix this?

Thanks in advance!

A delay of 9 seconds between printing jobs in TSC TE310 printer on Ubuntu 24.04 https://askubuntu.com/questions/1554403/a-delay-of-9-seconds-between-printing-jobs-in-tsc-te310-printer-on-ubuntu-24-04

I am facing a delay of 9 seconds between printing jobs. Printer is TSC TE310 label printer and OS is Ubuntu 24.04 LTS and connected throught USB. The 1st print comes instantly without any delay through the printer but job reamins processing for approx 9 seconds in printer queue. for 2nd jobs same repates.

Ubuntu 24.04 "Printing stopped" https://askubuntu.com/questions/1540169/ubuntu-24-04-printing-stopped

I'm new to Ubuntu, used DOS when I was a kid. Able to install Label Range LP320 Thermal Label printer through the terminal. I got "Printing stopped" message using 24.04.

Package list update of apt-daily.service is failing silently, update-success-stamp despite errors https://askubuntu.com/questions/1529622/package-list-update-of-apt-daily-service-is-failing-silently-update-success-sta

We have an unattended update setup. To make sure nothing slips, we check for pending security updates and trigger a warning if there is something available but not installed for a week.

Now we have a server with security updates not installed for a while because of the periodic package update failing without any indication of it. We would like to add a trigger to the monitoring to detect this, however, that seems not so simple.

apt update prints an error and has a non-zero exit status:

# apt update
. . . 
E: Some index files failed to download. They have been ignored, or old ones used instead.
# echo $?
100

However, the above did set the "success" stamp at:

# ls -l /var/lib/apt/periodic/update-success-stamp
-rw-r--r-- 1 root root 0 Oct 11 10:58 /var/lib/apt/periodic/update-success-stamp

Also, despite the error, the systemd service apt-daily.service is exiting with exit status 0.

How is it possible to detect that the daily package update is failing?

Ubuntu 22.04: Icons in system tray and many system applications replaced by red prohibited/stop symbol or legacy icons https://askubuntu.com/questions/1521958/ubuntu-22-04-icons-in-system-tray-and-many-system-applications-replaced-by-red

After updating my system a while ago, I noticed that multiple icons within the Desktop environment were replaced by compatibility mode icons (or at least very outdated ones) and red stop/prohibited symbols (see screenshots). These are all system icons meaning that also all system apps are affected (e.g. Terminal (+ symbol for multiple tabs), many parts of settings, the "Show apps" symbol in the taskbar, ...).

This guy seemed to have a similar problem, but his provided fix did not help in my case: Red icons in Ubuntu 22.04

I tried multiple suggestions by friends and colleagues and the internet, nothing worked or brought back the icons:

  1. Update icon cache
  2. Reinstall Ubuntu Desktop
  3. Reinstall Gnome
  4. Reinstall all packages using icons by searching the links that point to /usr/share/icons/

Does anyone have additional solutions I can try out? Missing these is especially frustrating in apps that heavily rely on their icons and when there is no additional description until being hovered.

If any questions arise, either due to missing details or my German language settings, I will happily clarify the question.

System Information:

  • Ubuntu 22.04
  • X11 Desktop
  • Gnome
  • No further customization

How can I set up multiseat with only one physical graphics card? https://askubuntu.com/questions/817982/how-can-i-set-up-multiseat-with-only-one-physical-graphics-card

I have an Ubuntu computer running 16.04, and I only have one graphics card.

Specs

My brother and I constantly fight over who gets to use it, so I'm trying to do everyone a favor and install multiseat.

  • I would be seat0, with the VGA port, a mouse, a keyboard, and the headphone jacks on the back of the computer.

  • He would be seat1, with the DVI-D port, a mouse, a keyboard, and the headphone jacks on the front of the computer.

  • We would share the Wi-Fi dongle to connect to the internet.

I am completely at a loss on how to do this. What files do I create, where do they go, and what do I put in them? A well-formatted answer (not an online guide) would be nice.

Configure Xorg to work from integrated GPU https://askubuntu.com/questions/547769/configure-xorg-to-work-from-integrated-gpu

I am using Ubuntu 14.04LTS, with an Intel CPU + integrated graphics, with a GTX650 GPU. I asked this question on SO but they said it was offtopic.

I want to use my GPU for debugging CUDA code and for that I need to change display to integrated only. This is the error I get when I try to debug it currently:

"All cuda devices are used for display and cannot be used while debugging"

I went into the BIOS and switched primary display to iGPU (the integrated one, HD4600). Nothing came out of the GPU ports anymore (in terms of display) and I plugged my monitors into the motherboard. Only one of the monitors works. Normally I have them like:

|[Monitor 1, VGA]| |[Monitor 2, DVI]|

In that configuration, with iGPU, nothing is displayed on Monitor 1 (it's black, but the computer knows it's there - the green light is on and all my windows open on it). The only way to get it to work is to swap Monitor 2 to VGA and Monitor 1 to DVI.

If I enter lspci | grep VGA into Terminal, I get this:

00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller (rev 06)

It isn't an HDMI connection, I don't know why it thinks it is. With the GPU, it knows it's DVI. Anyway...

This is the xorg.conf (if I change it, it just overwrites it):

Section "ServerLayout"
    Identifier "layout"
    Screen 0 "nvidia"
    Inactive "intel"
EndSection

Section "Device"
    Identifier "intel"
    Driver "intel"
    BusID "PCI:0@0:2:0"
    Option "AccelMethod" "SNA"
EndSection

    Device "intel"

Section "Device"

EndSection

Section "Screen"
    Identifier "nvidia"

    Option "AllowEmptyInitialConfiguration" "on"
    Option "IgnoreDisplayDevices" "CRT"

This is my 10-monitors.conf file in /usr/share/X11/xorg.conf.d/:

This still doesn't permit my CUDA code to be debugged. If I run lsof /dev/nvidia* I get:

COMMAND  PID     USER   FD   TYPE  DEVICE SIZE/OFF  NODE NAME
compiz  1659 cinnamon  mem    CHR 195,255          11805 /dev/nvidiactl
compiz  1659 cinnamon  mem    CHR   195,0          11806 /dev/nvidia0
compiz  1659 cinnamon   11u   CHR 195,255      0t0 11805 /dev/nvidiactl
compiz  1659 cinnamon   12u   CHR   195,0      0t0 11806 /dev/nvidia0
compiz  1659 cinnamon   13u   CHR   195,0      0t0 11806 /dev/nvidia0
compiz  1659 cinnamon   14u   CHR   195,0      0t0 11806 /dev/nvidia0

So I guess Compiz (X server?) is using it still. How do I stop it from using it?
