During network install ubuntu 2604 with server image and cloud-init I am getting error during ubuntu-desktop installation:

Last night my desktop worked perfectly normal. This morning the Super Key is misbehaving as if it's stuck or remapped.

1. Normally when I press the Super Key it shows Activity Overview, but now when I press Super it shifts the current workspace to the left and shows a new workspace on the right and I can only get back by hovering mouse over the Show Apps icon and use mouse wheel to roll up.
2. When I hold Super and press Left Arrow to cast open window to left side of screen it does that but also does the same thing by opening a new Workspace.
3. The other thing I'm seeing is that with multiple tabs open in Chromium when I can't switch to other open tabs, the system is forcing me to stay on the top tab.

I've rebooted twice and logged out and back in, but it's still broken.

I ran the following command to try and reset Super Key function, but didn't work.(Sorry but I don't know how to add a terminal command in a box the way I see others posting, so I'll put it in quotes.)

"gsettings set org.gnome.mutter overlay-key 'Super_L'"

--EDIT--

I shutdown the computer and restarted. The Super Key seems to be operating normally again in each of the ways described above. I'm going to leave this up for a few days though hoping that someone will perhaps have an explanation as to why this happened in the first place.

I have a HP Pavilion Notebook. I recently installed Ubuntu 24.04.4 on it. When I suspend the machine, the Airplane mode automatically turns on and cannot be turned off. I have tried toggling it in the settings but that doesn't work. Need help

My new CPU of RISCV64 architecture running on Ubuntu 24.4 is not able to detect the WACOM Intuos drawing tablet using the default GNOME drivers.

I've tried a backgrade of the GNOME starting the login with the "GNOME on XORG" option but the attempt was not successful as the Linux started very slow and showed blockings at access of the setup functions. I also was not able to run an X based diagnostics due to slowness.

My debug shows that the GNOME tablet window is active but does not show any device information. Back to default GNOME login, I see the following error:

rangepi@orangepirv2:~$ xsetwacom --list devices
Wayland devices found but this tool is incompatible with Wayland. See
https://github.com/linuxwacom/xf86-input-wacom/wiki/Wayland

I get this error when I try to change the Ubuntu desktop settings in Ubuntu 26.04 LTS. I have uploaded the error message. If there is any solution please share.

I installed Ubuntu 26.04 LTS in my HP Elitebook 8760w laptop. Although the installation finished successfully, the laptop doesn't start anyway.

My laptop boots to a black screen with this startup message.

As of now I have used Ubuntu 24.04 with no problems.

I am experiencing high battery drain on Ubuntu with my HP Victus 15. Despite several optimizations, powertop shows a discharge rate of around 20-22W at idle/light use, which is quite high for this hardware.

System Specs:

• Laptop: HP Victus 15

• CPU: AMD Ryzen 7 7435HS

• GPU: NVIDIA GeForce RTX 4050 (6GB)

• OS: Ubuntu

What I have done so far:

1. tlp: Installed and active.

2. Turbo Boost: Disabled to save energy.

3. GPU: Switched to integrated graphics using sudo prime-select intel (to ensure the NVIDIA card is powered down).

4. Monitoring: Using powertop to track consumption, but it consistently stays between 20-22W.

Are there any specific kernel parameters, drivers, or BIOS settings for the HP Victus/Ryzen mobile series that I should look into?

I use latest version of Ubuntu. Spotify title bar looks like Windows Vista and i dont want to see that.

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?

is there a DEB-Package for Thunderbird and Ubuntu 26.04? Thanks Karl

I installed a libadwaita app from flathub. I opened mobile view with ctrl + shift + m .

It looks like this (this is an example screenshot from the mobile view blog post, the actual app was different, but this issue is most likely generic):

Here I tried to take a screenshot by clicking on the screenshot button above, but the app crashed.

I tried running the app from terminal, and it says Vulkan is not supported in Haswell yet. How to fix this? I just need to take a screenshot. Surely I don't need accelerated graphics for something like taking a screenshot in mobile mode?

I am using Ubuntu 24.04 in an iMac made in 2013, which has Intel Haswell processor.

TPlink PCI 881ND wireless lan card is not getting detected in 26.04LTS,however it was getting detected in 24.04LTS

I'm using cage (the single app opener on the cli that runs individual apps without a desktop environment,) to run apps on wayland in an effort to remove all distraction. Can't have 50 different windows open and all that temptation if you only have one app to work with!

I start the apps like this:

cage thunderbird.

It works! but the windows (the window X, minimize and maximize buttons, and all the content inside the window) of the apps I run all look zoomed out and shrunken. Even if I zoom in to the content, the buttons on the top of the window "menu bar" part and the minimize maximize and exit buttons, all remain shrunken.

I want the window edges, window buttons, and everything in the window to not look miniature. How do I expand it all? All of it.

For a ASUS laptop (2016) with 16GB Ram was installed Ubuntu Desktop 24.04.4 LTS. It works very fast.

For other machines in the LAN with Ubuntu when the systemctl suspend command is executed as expected the OS gets suspended until any key is pressed, the login screen appears again.

But only this Asus: the command works, but is impossible to "resume" ... the screen remains black showing some messages (it's not possible to read it easily due to the font size). Please indicate where I can see that data in the logs to share here for more details. Therefore it's mandatory to hold down the poweroff button until the laptop shuts down and then to restart it again.

Note: Just in case this is a fresh install and there's an Nvidia graphics card (After I did do some research I read it could be a possible issue) without any driver installed because it's not required to make explicit use of the graphics card itself (for video games, graphic design, etc.).

Ubuntu 22.04 won't boot. Get a "Line endings are different ... set to pager=1" or something to that effect. Anyway I finally got Boot-Repair to fire up, but there was no "it was repaired" message.

Below is a link to what came up. Secure Boot is disabled. I did this using a USB drive. I have 5 partitions on the broken machine. I guess they're the sdb ones as the gpt3 says "unknown file". gpt 4 and 5 are Windows I believe.

It has both Ubuntu and Windows 10 installed on it. It's a Thinkpad if that matters. I searched and found a guy saying you can ignore the first 2 lines about the "MBR" and that some "EFI" partition didn't have a "Boot" thingy for it and to use "gparted" to add one.

I think that might be sdb2 here, but it shows a "boot" in the link. In the broken machine it shows gpt2 with and this is exact "efi /System Volume Information/" no boot or root.

Anyway, I'm pretty much new to all this. This originally was set up a few years ago by someone that's unable to work on it anymore, so I've just been doing searches and watching videos to try and figure it out.

https://paste.ubuntu.com/p/R73Zw2XkFx/

Is there a search function here?

Is there a way to get the possible answers to pop up again? I'd like to study them some more.

On Ubuntu Desktop, in Settings > Network > VPN, I've configured my wireguard VPN tunnel, including desired IPv4 and IPv6 DNS servers.

The tunnel works, but the operating system continues to use the DNS server provided by the DHCP server of the main network interface, not the one configured in wg0. I can observe this in wireguard.

Because of this bug, I am unable to reach interally hosted services using their DNS names.

How do I force Ubuntu to respect VPN mandated DNS server? If I manually query my desired DNS server that lives on the other side of the VPN, it responds correctly so it's not a connectivity issue. It's a typical DNS leak.

I can replicate this behaviour on Ubuntu Desktop 25.10 and 26.04.

I just installed Kubuntu 26.04 and, upon switching Konsole color scheme to "black on light yellow" I found out that the scrollbar becomes a garish bright yellow. This rings a bell, I think it happened already around 20.04, but it was fixed and certainly doesn't look like that in 24.04

Good (24.04):

Bad (26.04):

Any ideas how to fix it?

I'm using Ubuntu 25.10 I tried to fix it with several old solution without success.

These are the steps I tried: Screen Share Not working in Ubuntu 22.04 (In all platforms zoom, teams, google meet, anydesk , etc.,)

I'm from India, currently running Ubuntu 24.04.4 LTS. I am excited to upgrade to the newly released 26.04 LTS. However, even today's morning (Apr 25), my software updater couldn't find a newer version to upgrade to. Articles like (https://linuxconfig.org/upgrade-ubuntu-24-04-to-26-04) and (https://linuxize.com/post/how-to-upgrade-to-ubuntu-26-04/) suggest a manual upgrade via the terminal, first upgrading to a non-LTS version (25.10). I am not willing to wait till 26.04.1 LTS release.

How do I upgrade? Please help!

I wanted to connect to my Hyper-V Ubuntu 26.04 VM.

Fist, I connected from Win 11 by Hyper-V Manager Connection, but that doesn't allow me to copy & paste text between the Windows 11 host and the Ubuntu guest.

So, I enabled Settings -> System -> Remote Desktop -> Desktop Sharing in the guest OS (Ubuntu 26.04).

That worked; however, when the session locked after some time, the remote connection disconnected automatically. I found online I should enable Remote Control. I did so, but I am unable to connect to the VM from RDPMan (The server denied the connection).

Btw, grdctl returns a disabled status, despite the Settings -> System -> Remote Desktop -> Remote Login - Remote Login beign set to enabled

$ sudo grdctl status

It's a clean Ubuntu 26.04 installation.

What am I doing wrong?

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.

@will (again)The 22.04 drive was supposed to be my backup but something; my error, expert hack-age or a hardware problem scrambled GRUB when I tried to boot it on on a different desktop. Things went downhill from there. Safe backup is expensive at 3.2Tb and I am on a retired budget.

Just did a fresh install of Ubuntu 24.04.4 LTS and there is no HDMI sound out device listed to select for sound. Only "Digital output (S/PDIF) - USB Audio and HID" and "Analog Output - USB Audio and HID".

Did a bunch of digging, and tried any potential solution I could locate from updating intel drivers, to installing/using pulseaudio, and any other troubleshooting steps I could find. Even swapped out HDMI cable for a new one.

Also, for whatever reason, I can't get a command line listing of devices.

Still not seeing HDMI as a sound output option and sound out remains elusive.

At wits end.

Note that the HDMI audio works just fine for other devices connected to the monitor. HDMI audio worked also from the system under Windows 11.

I use KDE Connect between my phone and laptop on my University WiFi. Very often, the IP address changes and the connection stops working. I have to manually find the IP of the computer with the command ip address and put it in my phone and connect manually. The same thing happens when I connect to a different network.

Is there any way to automate the connection process? AFAIK know Apple's computers have some robust connection procedure with iOS devices.

I want to be able to do this for multiple computers with the same phone.

It seems that Aspera Connect does not work with snap-installed browsers tested as of Ubuntu 24.04.

This is notably the case for Ubuntu's default browser, Firefox. And it is also chromium's easiest install method by far.

On the other hand, I managed to use it fine from the exact same version of Firefox downloaded from https://www.firefox.com/en-US/thanks/ and ran as standalone.

Beyond the workaround of just using a non-snap installed browser, is there anything I can do to make it work on snap browsers so I don't have to have many browsers running around?

The break is documented on release notes up to release 4.0.0: https://www.ibm.com/docs/en/aspera-connect/4.0?topic=notes-release-aspera-connect-400

ASCN-1971 - Linux browsers installed using Snap cannot launch Connect.

Later releases don't document it anymore, but I doubt it got fixed, it's likely just an oversight.

While writing this I also noticed that Aspera for desktop, downloadable from: https://ibmaspera.com/help/downloads/desktop does work on snap Firefox for the diagnostics page: https://ibmaspera.com/help/diagnostics Furthermore, https://www.ibm.com/products/aspera/downloads says that Aspera Desktop is replacing Aspera Connect:

IBM Aspera for desktop is replacing IBM Aspera Connect

But unfortunately Aspera Desktop seems to require that the server be new enough, and didn't work on the actual server I'm interested in.

Tested on Firefox 149.0, IBM Aspera Connect browser extension 4.1.1.1, IBM Aspera Client 4.2.19.956, Ubuntu 24.04.

Having issues connecting with ASPERA to NCBI SRA; connection is "timing out". Tried the test connection page that IBM set-up and got the following error. Any suggestions? (Using FF).

Secure Connection Failed

Is it Possible to install Ubuntu 22.04 (Full) in a 25GB Partition or less space?

I tried the Ubuntu Minimal install option in the Installer, but seems like it does not install drivers or work, even though I checked the box in the Installer to install drivers.
So is it possible to install Ubuntu 22.04 (Full) in 25GB Partition or less space?

I am running out of ideas (and sources of ideas) on this one. I am getting a file-path from Audacious, and trying to get album art from the directory referenced. The info provided is correct, and works in terminal.

Things I have tried:

1. Redirected variable to a file, and looked with hexedit for odd characters.

2. Checked script for odd characters the same way.

3. Executed the script with /bin/bash directly.

4. Made a new script with only the non-functional code.

5. Because the path returned is relative [~/Music/Eagles/Desperado] have tried it as [/home/freebird/Music/Eagles/Desperado].

6. Because [Music] is a soft link to another drive have tried it as [/mnt/data/Music/Eagles/Desperado]

7. Have been using the Eagles because I didn't want to deal with [~/Music/Alice Cooper/School's Out] until I had the simpler case working!

8. IT does not have any CR's or other extraneous characters from editing on Windows or elsewhere - haven't used Windows for anything but Freecell and Spider Solitaire since 2007.

9. Nothing so far can resolve the resulting path into usability from inside the script, ALL work from the terminal (including cd).

Here is the actual error message from a recent try:

freebird@nest:~$ ~/check.sh
/home/freebird/check.sh: line 8: cd: ~/Music/Eagles/Desperado: No such file or directory

Any further suspects for me?

Here is the check script for testing:

#!/bin/bash
file_path=`audtool --current-song-tuple-data file-path`
echo > test2 ${file_path}
#${file-path}="/mnt/data/""${file_path:2}"
echo > testpath ${file_path}
cd "${file_path}"
#cd -P "${file-path}"
pwd
exit 1
if [[ ! -e "folder.jpg" ]];   # if no art work found
    then
    cp ~/Work/headphone.png /tmp/cover.png # put in placeholder
    echo "Placeholder"
 else
    convert "${file_path}""/folder.jpg" -resize 120x120 /tmp/cover.png # ready for showing
    echo "found cover"
 fi

It contains various 'test' additions still, the equivalent of scattered printf() to see what's going on :)

new version of testing script:

#!/bin/bash
file_path=`audtool --current-song-tuple-data file-path`
file_path=$(eval echo $file_path)
echo > test2 ${file_path}
${file-path}="$HOME"${file_path:1}
echo > testpath ${file_path}
cd ${file-path}
#cd -P "${file-path}"
pwd
exit 1
if [[ ! -e "folder.jpg" ]];   # if no art work found
    then
    cp ~/Work/headphone.png /tmp/cover.png # put in placeholder
    echo "Placeholder"
 else
    convert "${file_path}""/folder.jpg" -resize 120x120 /tmp/cover.png # ready for showing
    echo "found cover"
 fi

I have installed Anaconda (x64 Linux) and I am running its Python 3.

When I type which python, I get

/home/hinckelbc/anaconda3/bin/python

Now to display the version, I type python -V, and I get

Python 3.6.4 :: Anaconda, Inc.

Which is normal, since I am running Python 3 from Anaconda

If I launch Spyder from the terminal by simply typing spyder, it will launch and I see that the Python interpreter is indeed the Python 3 from Anaconda, as shown below:

Python 3.6.4 |Anaconda, Inc.| (default, Jan 16 2018, 18:10:19)
Type "copyright", "credits" or "license" for more information.

IPython 6.2.1 -- An enhanced Interactive Python.

!which python
/home/hinckelbc/anaconda3/bin/python

! python -V
Python 3.6.4 :: Anaconda, Inc.

The Spyder running on my machine is the following:

hinckelbc@BCArg:~$ which spyder
/home/hinckelbc/anaconda3/bin/spyder

In order to avoid opening the terminal all the time and typing spyder, I have created the following spyder.desktop file ~/.local/share/applications/spyder.desktop, which looks like this:

[Desktop Entry]
Type=Application
Name=Spyder
Exec=/home/hinckelbc/anaconda3/bin/spyder
Icon=/home/hinckelbc/anaconda3/pkgs/spyder-3.2.6-py36_0/info/icon.png
Terminal=false

I then could find Spyder with the Super key, which was then added to by launcher, by dragging and dropping (Gnome 3, Ubuntu 17.10)

However, when I open Spyder by clicking on the icon, now on my favorites, I get:

Python 3.6.4 |Anaconda, Inc.| (default, Jan 16 2018, 18:10:19)
Type "copyright", "credits" or "license" for more information.

IPython 6.2.1 -- An enhanced Interactive Python.

! which python
/usr/bin/python

! python -V
Python 2.7.14

Which does not agree with the python interpreter I set manually on Spyder, as shown below:

Does anyone know how to solve this, i.e. to get Python 3 running on Spyder with the desktop icon I have created and added to my favourites?

I have an x64 Ubuntu 14.04.3 LTS virtual machine running the hardware monitoring and status software Nagios. The VM seems to be kernel panicking once every 5-9 days. I am unable to pin down the cause.

I am currently the only person that uses Nagios on this machine. When it kernel panics, it's not being used by anybody (and to my knowledge, not doing much else besides receiving monitoring updates from other computers). Additionally, the VM is only available on the local network, and I've regularly kept everything up-to-date using sudo apt-get update && sudo apt-get upgrade.

The following boot messages show the VM kernel panics. Every kernel panic seems to be a slight variation of one of these two boot messages:

[374230.947096] Kernel panic - not syncing: Fatal exception in interrupt

The VM runs on Hyper-V on a computer with Windows Server 2012 Standard installed. However, the server runs 6 other VMs without incident (including Ubuntu 12.04 and CentOS 6 VMs).

Is it possible that Hyper-V integration services or drivers are at fault? I keep seeing hv_storvsc and references to Hyper-V in the kernel panics and am wondering if the Hyper-V drivers in 14.04 are subpar or have known issues.

The VM has been in operation for about 1.5 years, but these problems have only started surfacing a few months ago, if I recall correctly.

dditional information about the virtual machine:

• 1 virtual processor assigned
• 1024MB RAM
• Hard drive on IDE Controller 0
• Virtual hard disk resides on the server's C:\ drive
• All integration services are enabled for the VM, including: operating system shutdown, time synchronization, data exchange, heartbeat, backup (volume snapshot)
• Replication is enabled to a server in the same rack with identical hardware

Additional information about the host server that runs Hyper-V:

• Powershell script runs every night that runs Windows Backup on all VMs to a local external hard drive
• Motherboard: http://www.newegg.com/Product/Product.aspx?Item=N82E16813128577
• CPU: AMD A8-5600K quad-core 3.6GHz CPU
• RAM: 32GB (4x 8GB) CORSAIR Vengeance DDR3 1866
• All RAM has been tested thoroughly with memtest86+
• System has been stress tested with Prime95
• System has been in operation for about 2.5 years
• 2x 1TB HDs set up in RAID1 using the motherboard's onboard RAID controller
• Raid software has not given any indication of problems with the array

Any help would be appreciated. I've been Googling around for days and haven't come up with any reasonable theories.

I used to have a 64GB micro SDXC card in my mobile phone. But last week, after the phone crashed and I had to restart it hard, the SD card was not mounted anymore. The phone tried for 5 minutes but then told me I could safely remove the SD card.

So I put the SD card in the adapter and inserted it into my laptop computer, Windows 7. Nothing happened. Windows recognized the SD card but clicking it led to no reaction.

Then I got out my pen drive Linux with Ubuntu 14.04-1 LTS. And I got some results. When I inserted the card I got a dialogue telling me that a medium with digital photos had been detected and asked me for further actions. When I selected "open folder" Ubuntu crashed hard (Kernel panic).

I searched for help and found https://unix.stackexchange.com/questions/53542/how-to-determine-the-filesystem-of-an-unmounted-device.

Here is the output for the commands recommended there:

/dev/sdc1: x86 boot sector

Executing df -T leads to the same crash as above.

I would like to know which programs or commands to use in this situation in order to get at least my photos off the SD card or even better, all files or an image file. If the SD card itself is lost, so be it, I only need the data.
