I used a tool that allows me to boot from the iso by making a specific partition. I installed the Ubuntu onto a 8gb USB drive(it is NOT a live installation, the USB drive is the os)

I just did a fresh install of Ubuntu Studio 26.04 LTS on my desktop system. Previously I’ve been running Ubuntu Studio 24.04 LTS. The driver for 24.04 is 580.126.09 and the 26.04 driver shows as 595.58.03. I have four displays arranged with three side by side horizontally and the fourth above them. The three are at resolutions of, from left to right, 1680x1050, 1920x1080, and 1680x1050. The one above them is 3840x2160.

The setup described above works well on the 24.04 system with all displays showing as running at 60hz. The 24.04 system runs on xorg and the 26.04 system runs on wayland.

The issues seem several. On the new system, the displayed rate is ~29.97 for all displays. Also, the 4k display does not display at all at 4k. If I set it to 1920x1080, though, it does display. Third, when I move the mouse between displays, there is a noticable hesitation in crossing between them. There are also occasional hesitations in movements within a single display’s display area. Lastly, at seemingly random times, the system will freeze with one or more displays turning to frozen video frazz.

The nouveau driver behaves similarly.

I have no idea how to proceed in solving these issues and would appreciate any input to that end.

Thanks,

BabaG

Short story long: Back well before the pandemic I made the mistake of buying the absolutely last plasma TV that was ever sold by my local BestBuy -- a Panasonic TC-P50x60 (50 inch). Because it had been discontinued and all the TV manufacturers were moving 100% to LED TVs I got a great deal on it, however...

What I didn't find out until much much later was that some dumbass firmware engineer @ Panasonic decided to save a few cents on EPROM by leaving out some of the normal menu options that were present in all other Panasonic TVs. In particular, this thing has an overscan of exactly 2.5% on all four edges, top, bottom, left, and right, and this cannot be turned off. (Trust me. I've investigated this eight ways to Sunday, called tech support, checked every menu option & combination of menu options. The overscan really and truly cannot be turned off on this model.)

Anyway, fortunately for me OpenELEC on my cheap low end x86 Home Theater PC... which I'm still running even though the OpenELEC project shut down several years ago now... allows the user to adjust the HDMI output to compensate for monitor overscan just like this. (I think that OpenELEC's successor, LibreELEC, supports overscan compensation too.)

Anyway here's the problem: For reasons of my own I want to now replace my HTPC with something a bit newer and I'd like to be able to access full-blown Linux (specifically Ubuntu) on that, with the display being my trusty old Panasonic TC-P50X60.

So, question: How can I do this?

Just dropping a fresh install of Ubuntu 24.04.4 onto my newer x86 HTCP and wiring it up (HDMI) to my TC-P50X60 produces unacceptable/unusable results because of the TV's overscan. I've tried several different things to try to get what's displayed to come out smaller, to compensate for the overscan, and so far nothing as worked. I already figured out that in order to have any hope I need to log in to Ubuntu using the X option, rather than the Wayland option, because then at least I can run xrandr (and/or xvidtune) but even after doing that, nothing I've tried is working. Xvidtune refused any attempt for me to change anything. Trying xrandr --scale (with different values) just produced error messages, and no other effect. I've also tried "xrandr --output HDMI-1 --set underscan on" which also just produced error messages (and no effect). Lastly, I tried: "xrandr --output HDMI-1 --transform 0.8,0,0,0,0.8,0,0,0,1". That "worked" but it only had the rather bizarre effect of making all of the displayed icons & fonts bigger, but not actually changing the total size of the entire desktop at all.

Any help or guidance appreciated.

Note: I'm an experienced UNIX/Linux user, but I know next to nothing about graphics, displays, windowing systems, desktop environments, compositors, etc., etc., so please be gentle with me. Thanks.

So firstly I want to say I’m a complete newbie with Ubuntu. I have used it on a spare laptop for a few years but I don’t have much understanding, if I have any problems I come straight here.

So I needed to transfer files to an external drive to move to my main pc. I for some reason cut and paste and didn’t copy them and during the transfer the external drive must of disconnected and I lost all of my files from Ubuntu laptop and they also didn’t transfer to the external drive.

I used test disk to try and recover any lost files and everything seemed like it worked but then upon rebooting the laptop I am now stuck at “Minimal BASH-like line editing is supported” I have tried using a usb version of Ubuntu to try and fix the boot (which has worked for me in the past) but this time when trying to install the boot-repair i just get the message “unable to locate package boot-repair”

How badly have I messed up or is this fixable?

I also didn’t continue the transfer of files after the original transfer fail so now I can’t access the remainder of what I still had on the laptop

The hardware requirements for Ubuntu 24.04.x are: 2GHz processor & at least 4GB of ram.

Has anyone ever actually tried to run 24.04.x on a system with only 4GB ram? I have to ask because I've been trying it, repeatedly, and every time the system gets to the point where it has to start swapping (as shown by top) SOMETHING crashes... either Firefox or gnome-shell or the kernel. (That last one is just a guess, but when the whole system locks up with a totally black screen I gotta think that's a kernel panic.) In one case where my keyboard & mouse clicks (but not mouse movements) suddenly stopped working, after a reboot I got some message asking me if I wanted to report an error to Ubuntu central and when I looked at the details it said that gnome-shell had gotten a SIGBUS! Yikes! THAT should never happen!!

So anyway I was able to repeat these failures, consistently, on 2 different, mostly identical systems, specifically my two HP T620 thin clients, each with a AMD "Kabini" GX-415GA (quad core), each having only 4GB ram installed and each with a Sandisk X600 128GB M.2 (SATA) "hard drive" installed. (The only differences between the two is that one has a WiFi card installed & the other doesn't and one has been updated to the latest HP T620 BIOS and the other hasn't yet... but the BIOS rev. apparently makes no difference to these mysterious crashes. I know. I checked.)

I have already ordered more memory for these machines, and yes, clock speed for these CPUs is only 1.5GHz, which doesn't meet the strict letter of the 24.x.x hardware requirements, but setting that aside, even if I put 8GB in each of these machines, if my guess is correct that there is a serious memory management bug underneath all these repeated crashes then what happens when and if I max out the 8GB and start swapping? Obviously the mysterious application, gnome-shell and (possibly) kernel crashes will reappear. So just adding more memory is obviously NOT a proper solution.

I'd like to hear whatever anybody might have to say about all this. Opinions welcome. Should I just give it up and accept that modern Ubuntu is just never going to work on 12.5 year old hardware? Should I file a formal bug report? If I do, will anybody even care to investigate, given that this hardware almost qualifies as "antique"?

As I say, I own two of these systems. They are slow enough to be perfectly useless as Windoze machines, and if I can't run Ubuntu on them then at best I could only maybe run LibreELEC on them (but maybe that would crash too). As they sit now they're really just expensive paper weights.

If anyone was at all interested in investigating these problems then I would be more than happy to loan one of these systems to that person for, say, 30 days, and I'd pay for shipping both ways (continental US only).

These were pretty cool machines in their time, and for most stuff, performance-wise, they still beat the pants off a Raspberry PI 4, and with a case & power supply they can be had used, off eBay, for less than half the cost of a PI4 + case + power supply. So I think that it's a damn shame that the most popular Linux distro won't support them in their standard (4GB) configuration. (There are, I'm sure, several hundred thousand of these exact machines out there in circulation. They were real popular for offices, back in the day, in part because they're fanless, passively cooled, and thus, dead silent.)

I installed Octave, and the Bengali fonts in many websites such as Wikipedia (all articles) are rendering quite badly afterwards in both Firefox and Chromium.

Example: The font is very small, and it looks somewhat broken in this Wikipedia article:

How to fix this issue?

I have all these checked:

Secure Boot → Enabled

Secure Boot Mode → Standard

on my ver 2.22.1289 2025 american megatrends BIOS

mokutil --sb-state also shows SecureBoot enabled in the liveUSB's terminal

Yet it still gives me this:

INVALID_SECURE_BOOT_MODE error with secure boot policy (PCR7) measurements: deployed mode should be enabled in order to generate secure boot profiles

I also tried to restore to factory reset multiple times, but that didn't help.

Anyone have met the same situation as me?

I am trying to install Kubuntu 26.04 alongside of Kubuntu 22.04 and Windows 10. The installation seems to finish properly, but upon reboot, the partition where 26.04 is located is not visible in GRUB. If I boot in 22.04, the partition is not visible under the 'Devices' of Dolphin, but is visible with LSBLK and I can see it inside the Media folder of 22.04. The Windows partition is visible, as well as the 22.04 (obviously). Running a update-grub from 22.04 will make the option appear in GRUB, but it won't boot, since it won't find the kernel (which is present within the 26.04 partition, viewed via the Media folder). Upon installation, I tried to install 26.04 in an empty space of the SSD (creating a EXT4 partition) or also by sharing the 22.04 partition. Once 26.04 is installed, the partition becomes invisible.

One last thing... Update-Grub finds the 26.04 partition with the grub probe and it defines as Unknown filesystem.

Any idea?

Thanks

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

The tablet is visible at ID 06, but does not interact with the Linux mouse (pointer) function.

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'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?

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.

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.).

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 am attempting to try out the new 26.04 version of Ubuntu Unity. I have downloaded the ISO ubuntu-unity-26.04-desktop-amd64.iso and put it on a Ventoy stick and am able to boot OK, to the point where it brings up a login prompt with a dropdown at the top that only shows 'Other' and a username and password field. I thought that user ubuntu with empty pwd should work but it says it is invalid. I have tried unity, ubuntu-unity and other combinations but nothing seems to work.

What am I doing wrong please?

Wifi does not work in the live session, but I have wired networking available. However, if I want to enable wifi connection, is it a good idea to install a proprietary driver for the hardware. And is it a problem, if I boot the USB Ubuntu in another computer that uses a different driver when it has the additional driver?

How can I install the driver?

I tried running sudo apt update with the following output:

And I tried to install software-properties-gtk. That one is needed in Ubuntu to install additional drivers, right?

It is 8GB flash drive and the laptop has 8GB RAM.

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!

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).

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

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

When I type which python, I get

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 just installed Xubuntu alongside an Arch-based distro. The problem is that Grub2 does not detect the (btrfs) partition of the previous distro, so I can't boot from it. I have already tried update-grub2.

By the way, that btrfs partition used to boot alright from Grub2, before I installed Xubuntu.

What can I do?

A certain cellphone maker has changed the default format of taking pictures to HEIF (.HEIC, High Efficiency Image File Format), without asking the users (although there is still the option to use jpeg/jpg).

Is there an app/program on Ubuntu that can open and/or convert HEIF-pictures and even let them be edited?

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:

fdisk:

sudo fdisk /dev/dsc1 -l

file:

sudo file -sL /dev/sdc1

/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.
