My microsd card will not mount in the built in sd card reader or in a usb adapter. It worked fine earlier in the adapter, then I ate dinner, came back, and now it plays the noise when I plug it in, but doesn't show up in files, does show up in discs, but will not let me mount it. (no play button/all the options are grayed out in the drop menu. another usb drive is working fine.)
Fresh install Ubuntu 22.04.5. All updates applied. The updates did fix the initial no wifi issue. All the other hardware seems to work. External HDMI not tested.
Changing color profiles have no effect. That includes the Test: Swap red and green profile.
Switching between Wayland and X11 no effect.
Doing a list of available drivers gives no results, but it does appear to be a driver issue. Current driver Tigerlake-LP GT2 [Iris Xe Graphics] (Rev 01) -- modules: i915, xe. Is there a driver configuration file?
This appears to be an old problem but none of the found fixes have had any results
Any suggestions appreciated.
Hi i'm currently now using lubuntu 24.04 lts, i trying to install ubuntu using command "apt install ubuntu-desktop" and after choose ubuntu DE (already use ubuntu, ubuntu xorg) in top left option lubuntu login (sddm), the input keyboard and touchpad click not work, but cursor at touchpad work fine.
i've trying suggested solutions, like blacklist modprobe intel_vbtn & intel_hid, install x-org input/libinput, install generic hwe 24.04, wayland = false and update grub add some params nopnp, noinputloop, and else.
Does any solutions to fix that, by the way i'm using asus zenbook UX433FN ?
I have had this Ubuntu File Server at home for about 15 years. Recently, the motherboard and CPU died and I had to get a new one of those. All good. Install Ubuntu 24.04 LTS successfully, no issues.
All the 4 HDD's were there although mounted at the location as specified in the old setup.
I created 4 separate directories (/mnt/sharefiles/media_1, /mnt/sharefiles/media_2, /mnt/sharefiles/media_3 and /mnt/sharefiles/personal) with the intent to mount these 4 drives there. 3 of these are working fine. The 4th one has issues, supposed to be mounted here :- /mnt/sharefiles/media_2
The impacted drive is : /dev/sda1
Output of lsblk -l
sda 8:0 0 0B 0 disk
Output of lsblk -f
sda
└─sda1
Output from my attempts to mount the drive:
agarwaldvk@MyHomeServer:~$ sudo mount /dev/sda1 /mnt/sharedfiles/media_2
[sudo] password for agarwaldvk:
mount: /mnt/sharedfiles/media_2: special device /dev/sda1 does not exist.
dmesg(1) may have more information after failed mount system call.
I have done a lot of reading to see if I could fix it but I couldn't, hence am looking for some help here to have my data at least recovered.
I wanted to attach the output file from the dmesg command but I don't know if I can as I can't find the option to do so.
I have mounted them updating the fstab file - the entries are as follows :-
# <file system> <mount point> <type> <options> <dump> <pass>

In the Disks section, I can seem to be able to 'Repair FileSysstem' as its not available
Any suggestions please on what I can do to fix up the issue.?
Apologies if this is not the right place to post this.
I have a laptop with an Nvidia 3050 and Ubuntu 24.04 which failed to boot recently as I upgraded to the 6.8.0-90-generic kernel:
...it hangs on:
[ *** ] Job gpu-manager.service/start running (34s / no limit)
This continues on indefinitely if left. It seems that it's a problem with the graphics driver, so searching around revealed the general wisdom seems to be to run this command:
sudo ubuntu-drivers install
....which installs the 570 nvidia driver.
However, this did not fix the issue.
I also tried going into the grub boot options and booting into the kernel 6.8.0-88-generic, which works fine but the Nvidia driver doesn't load:
$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
$ lsmod | grep -i nvidia
$ glxinfo
...
client glx vendor string: Mesa Project and SGI
...
Vendor: Intel (0x8086)
Device: Mesa Intel(R) Iris(R) Xe Graphics (ADL GT2) (0x46a6)
...
OpenGL vendor string: Intel
...
...so to this end, I'm a little stuck on how to debug this, because this happens before the login prompt, I can't debug the issue interactively.
Does anyone know either a) if this is a known issue with the 6.8.0-90 kernel, or advise on debugging such a situation?
My desired state of affairs is a working nvidia driver and a working boot on the latest available kernel (6.8.0-90).
I've been trying to install a plugin for my HP LaserJet M140we to get the scanner to work on my Cinnamon, but I have run into the issue of Python gobject/dbus is not being allowed to be installed without any further prompting. I am uncertain how to proceed as I would love to be able to scan documents (drawings, pamphlets, handouts, recipes, etc) into my computer. Is there currently a workaround? I don't have a custom Python to my knowledge, as I had requested a store to install Cinnamon for me. (I had somehow trashed two prior thumbdrives and wasn't wasting another $10 to do so again.)

Seems to be the script I got when looking up my OS fully. The System only gives the "Pretty Name" it seems.
I consider myself a beginner as far as the Linux world is concerned. Please bear with me. I searched the topic but it appears to be a different problem here.
I wanna play a bit with one of my RaspberryPi and setup a Nginx server to explore it's reverse proxy function. Hence, latency is a topic. The issue with this RPi (tried setting it up multiple times) is, that the eth0 interface isn't automatically activated. That's weird because the interface is directly connected to my router. I can activate the interface without any errors and receive an IP from the DHCP server immediately when I fire the command dhclient eth0.
For whatever reason, after every reboot or some time, the eth0 interface goes down and the RPi uses the wlan0 interface instead. I tried amending the config file to deactivate the wlan0 interface but that caused the device to not be reachable at all. Looks like only the manual dhclient call can start the eth0 interface.
What should I check or change to make sure there's no hardware issue and why does my RPi not preferably use the eth0 interface as it should? (It's freshly installed, no changes made to the default network configuration that I'm aware of)
Thanks so much for any help!
When my laptop wakes up from a power management suspend/sleep I have a monitor that doesn't start to receive a signal again. When I unplug it and plug it back in the monitor starts to get a signal again.
I have 2 external monitors,
My base system is:
Below is the debugging info that I have collected so far.
journalctl | grep -C 100 -E 'PM: suspend (entry|exit)). There is a warning about the HDMI monitors about it being a weird aspect ratio. "consider adding a quark"sudo get-edid | parse-edid is of limited help. It fails with errors on monitors that work and the one with a problem.I dont think its a driver issue or and issue reading the monitor information from the device itself since the monitor eventually comes back if its unplugged and plugged back in.
What are the next log files I should look in, or what is the next thing I should try?
I recently installed the new Kubuntu 25.10 on my Asus X556UQK laptop (Intel + NVIDIA 940MX). The installation went smoothly, but after the first reboot, I was stuck on a dark blue/black screen and couldn't reach the login manager (SDDM).
If you are facing a similar issue where the system boots but the GUI doesn't start, here is how I fixed it:
Access the Terminal (TTY)
When stuck at the black screen, press Ctrl + Alt + F2 (or F3/F4). This allowed me to log in via the command line.
Update and install NVIDIA drivers
It turns out the default open source drivers were struggling with the new Plasma 6 environment on my hardware.
I ran these commands:
sudo apt update
sudo apt full-upgrade
sudo ubuntu-drivers install
The last command automatically detected and installed the NVIDIA 580 (or 550) proprietary drivers.
Disable Wayland (if needed)
Kubuntu 25.10 defaults to Wayland. Since NVIDIA and Wayland can sometimes conflict on older hybrid laptops, I forced the system to use X11 for the login manager:
Open the SDDM config: sudo nano /etc/sddm.conf
Add these lines:
[General\]
DisplayServer=x11
Save and exit (Ctrl+O, Enter, Ctrl+X).
Final Reboot
After a sudo reboot, the system finally loaded the Plasma 6 desktop perfectly.
Specs:
OS: Kubuntu 25.10
Kernel: 6.17.0-8-generic
GPU: NVIDIA GeForce 940MX (NVIDIA 580 drivers)

looking for a GUI screen video w/audio capture app for Ubuntu 24.04lts - search on AskUbuntu pulls up stuff 10-15 years old with things no longer in existence... same with search engines.
Ubuntu Software only has recording junk - most do not even open, have no GUI, or open and locks up like not working with Wayland.
That print screen thing only records video - no audio.
VLC says can capture desktop but has no record button or way to select...
I can use my laptop's hdmi output to record screen to my DVD recorder, bring the burned DVD to the laptop and use handbrake to make mp4 recordings... seems there should be something more user friendly!?!

I have access to a dual Grace Hopper GPU on a remote server. I was told that it should be possible to use the two GH200 on this dual chip as a single GPU. I want to do that because my application requires a lot of RAM, which I bust on a single GPU.
However, I'm having difficulty finding information as to how to do this, and all jobs I send seem to be directed to either one GPU or the other.
Can someone point me to the relevant information, or just tell me if I'm wrong?
I run my scripts in python. Can someone point me in the right direction? The output of the nvidia-smi command is:

I have a PXE server set up, network booting from the Ubuntu 22.04.1 live server ISO. I am attempting to automate the Subiquity installation process using cloud-init.
The kernel command line parameters I'm using are:
/jammy/22.04.1/vmlinuz ip=dhcp url=http://myserver/isos/ubuntu-22.04.1-live-server-amd64.iso ds=nocloud-net;s=http://myserver/config/
The ISO is about 1.5GB.
The files user-data and meta-data both exist in myserver/config/.
The machine has 4GB RAM.
I can successfully go through the install process manually if I don't use cloud-init. However, when attempting to use it, the cloud-init process keeps getting killed after running out of memory during the startup sequence, then the installer hangs on "waiting for cloud-init...".
I hand-wavily tried limiting the ramdisk size to the size of the ISO via a ramdisk_size=1500000 kernel parameter but it had no effect on the end result.
I also tried using the cloud-config-url parameter (instead of ds) to point directly to the user-data URL but that just seemed to be ignored and the manual install process ran.
I tried looking for a smaller ISO image but discovered that the minimized ISO images haven't been available for Ubuntu since 20.04.
I tried following these instructions (as closely as possible) to modify the ISO itself and add user-data directly into it. The ISO modification process worked but cloud-init still ran out of memory on boot.
I'm not sure why cloud-init needs so much memory. Is there some way to make cloud-init work on a machine with 4GB RAM? Alternatively, is there some way to have it use the ISO without downloading the entire thing to RAM first (which I'm assuming would leave enough memory for cloud-init to run)?
Please let me know if I've used any terms incorrectly or am missing any info, this is my first time trying to set up an automated network Ubuntu install; I am used to the Debian installer.
In the last week, after some update, either firmware or Ubuntu update, the backspace and Enter buttons don't work after I open the lip of the laptop. I can't figure out the incantation that will make those buttons work so that I can login.
Sometimes Fn+F7 makes it work, sometimes just waiting 2 minutes, sometimes it's Ctrl+F7, etc. I've tried a few and mostly can repeat the sequence. The buttons work perfectly after logging in or after a reboot, so something in the suspend or resume is locking up these keys. Do you have any idea on how to diagnose this so I can reply with better detail, or ideas on how to fix it?
UPDATE 1 day later:
I tried not pressing random keys and just waiting: works. the wait time was 5mins. Also got a clanker to help with diagnosis. It told me that keyboard loads fine but power management was the issue. here is some of the output.

update 2: its desktop ubuntu. @guiverc i rolled back to the 36 kernel . did not solve the problem i reinstalled a 24.04.03 LTS. did not solve the problem. well, not totally, its sometimes works and sometimes does not. which is terrible for testing and feedback. i am sure they worked in BIOS menus. But im in the bios for a few minutes only. so i have not had a non-working bios experience.
for now, im using some keyboard remapper. del=backspace and rightctrl=enter.
i am hesitating ordering a replacement keyboard because official manual says i need the whole plastic cover and stuff with the membrane keyboard. but if its software related problem, then replacement hardware wont solve it.
i wonder if this was a firmware update that was done prior to the problem and the firmware was badly coded/tested. its hard to know because firmware description is cryptic and ubuntu doesnt have date displayed on update date. i dont want to be rolling back firmware if i can avoid it.
I often find myself signing PDF files I receive via email, which I have to print, sign by hand, and scan. It's a huge waste of time and frustrating. I already have a PNG image of my signature, and I'm convinced a simple tool that overlays the image onto the PDF file I need to sign would be enough. There are some rather dated (13-year-old) solutions online, some geeky (using Ghostscript) or software from external repositories, or LibreOffice, which however alters the PDF upon import. We're now on Ubuntu 24. Is there any software that can easily overlay an image onto a PDF page without using scripts or dubious apps? Thanks.
Does GNOME Builder have a source code browser (sometimes referred to a Symbols View)?
I would like to see the variables and functions in my Python file listed in the left panel. Clicking on an item in the panel should scroll my file in the right panel to the place in where the variable or function is defined.
UPDATE:
Here is a Screenshot of Gnome Builder. I installed it in Ubuntu 25.10 using
apt install gnome-builder
I created a new project named "Test" using the "Python" language, and the "GNOME Application" template.
I have opened the main.py file. As you can see, there is a function called do_active() in the TestApplication class.
I do not see the classes nor do I see the methods in Gnome Builder. There is no option to add a Symbols panel to the left or right of the Gnome Builder interface.
Additionally, if I try to search for the symbol do_active(), no results are found (as shown in my screenshot).
Please guide me on how to make the Symbols panel visible and how to have Gnome Builder recognize the symbols in my code.
I am running Kubuntu 22.04.3 LTS with KDE Plasma 5.24.7. I would like to use the Line Out (Built-in Audio Analog Stereo) as audio output. These are the audio devices shown by lspci:
$ lspci -knn | grep -i audio
00:03.0 Audio device [0403]: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor HD Audio Controller [8086:0c0c] (rev 06)
Subsystem: ASUSTeK Computer Inc. Xeon E3-1200 v3/4th Gen Core Processor HD Audio Controller [1043:8534]
00:1b.0 Audio device [0403]: Intel Corporation 8 Series/C220 Series Chipset High Definition Audio Controller [8086:8c20] (rev 05)
Subsystem: ASUSTeK Computer Inc. 8 Series/C220 Series Chipset High Definition Audio Controller [1043:8573]
I connected the stereo speakers with a jack cable to the Line Out (Built-in Audio Analog Stereo); stereo headphones are also connected with a jack to the front-panel audio output of the case.
This way, the system detects that a jack is connected to Line Out and Line Out is automatically selected as default sound output line. Also, almost every time I click in the sound icon in the bottom right corner of the task bar (near the clock), I hear a spike in the audio speakers. The same happens if I run PulseAudio.
However, if I try to play anything (from YouTube, from VLC, ...), there's no audio coming out from the speakers. If instead I select the headphones, they work as expected.
In PulseAudio Volume Control -> Output Devices -> Port, it is shown "Line Out (plugged in)" with almost 100 % volume. If I play something, the visual sound level even moves according to the audio, but there's nothing coming out from the speakers, as if "Mute" was active (but it isn't).
What could it be the problem?
Sorry if this question has already been answered, but there is a lot of information online and I am not sure what to do.
What I want, is a system where I can boot into Ubuntu or Windows from my computer startup. I think this is done by using GRUB but I'm not sure.
Here is everything that I have:
I have 3 disks:
/dev/sda which is a 250GB HDD formatted to ext4 and is just for my files and stuff
/dev/sdb which is a 240GB SATA SSD that contains Linux and /home
/dev/sdc which is a 160GB HDD formatted ntfs that contains Windows
When I boot up my computer, it boots into GRUB and asks me what I want to boot up.
To get this to work originally, I had to change some stuff in /etc/default/grub. Here is what it looks like (top half only):
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'
GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=menu
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""
I changed GRUB_TIMEOUT_STYLE from hidden to menu, and I changed GRUB_TIMEOUT from 0 to 10.
The GRUB menu though only shows Ubuntu, Advanced Options for Ubuntu, and 2 memory tests.
After that I installed Boot-Repair using:
$ sudo add-apt-repository ppa:yannubuntu/boot-repair
$ sudo apt-get update
$ sudo apt-get install -y boot-repair
and I ran it using $ boot-repair, clicked Recommended Repair, and it output:
GPT detected. Please create a BIOS-Boot partition (>1MB, unformatted filesystem, bios_grub flag). This can be performed via tools such as Gparted. Then try again.
Alternatively, you can retry after activating the [Separate /boot/efi partition:] option.
According to other answers, I think I need to create an unformatted partition and give it the flag bios_grub, but I'm not sure.
Extra info:

What happened?
Everything was working correctly, but then i did the following: Today, i started Ubuntu not with my current kernel like normally, but with an older Kernel, because i wanted to try something out.
After is started Ubuntu with the older kernel, i noted that all my gnome settings are gone/missing/disappeared.
For example:
--> My Desktop looks pretty empty, only the icons for folders/files are visible.
At this point, i was not frightened about that, because I thought, that the reason for all these "missing settings" was, that i am on an "older" kernel right now. So, i thought, my settings will be there again as normal, after changing back from the older to my current kernel.
BUT: After changing back to my current Kernel, all settings like Background-Image, Panels, ... are still missing :-(
I have a feeling, that the process, that runs gnome, does not have the correct access-rights anymore to read all my config-files (for Background, mouse-speed, Nautilus-settings, ....).
When logging in with Guest-Account, all Panels and Menu-Bars are there as normally adn are working correct. -> That means, all installed gnome packages are still working correctly, no need for any update or installation of things. It seems, its just a "settings-problem".
Can anyone help??
THANKS!!!!!
I am using:
My mullvad VPN was working, then I upgraded to 18.10. Now when I use their UI client, it connects fine, but DNS is not working. I can ping google.com by IP but not by google.com.
I can resolve it by specifying the interface:
>resolvectl query google.com
google.com: resolve call failed: All attempts to contact name servers or networks failed
>resolvectl -i tun0 query google.com
google.com: 216.58.212.174
-- Information acquired via protocol DNS in 1.1ms.
-- Data is authenticated: no
The man page for resolvectl says this about the -i option:
Note that this option has no effect if system-wide DNS configuration (as configured in /etc/resolv.conf or /etc/systemd/resolve.conf) in place of per-link configuration is used
So is my system using per-link configuration? How do I check that?

I've noted that the Ubuntu ISO file is bootable on systems with BIOS and with UEFI. I've remastered Ubuntu from scratch, and I'd like my ISO file to be bootable in both cases.
My remastering of Ubuntu is done by first installing debootstrap into a chroot jail, and then gradually adding files until I have all desired programs, however the resulting ISO file is only bootable on a system with BIOS.
I believe I need some different magic with mkisofs, but what about the files in EFI/BOOT? What is the origin of those files? Is there anything else I need?

As I understand this message clinfo is installed. However, I can't find it anywhere in my PC. It did not appear in the side bar on desktop nor I can find it by Search your Computer. Where is the problem? Thanks!
EDIT:
from the terminal: dpkg -L clinfo

After finally finding the right folder I right clicked on clinfo and pressed "Run", but nothing happens.
I get the standard behaviour when I press this combination which sort of switches off the display and I know that I can go back to it by hitting Ctrl+Alt+F7 but the IDE I use has a pretty useful action fired under that shortcut which I want to take place rather than the display going off.
PS. I am on Gnome with Compiz.
I installed my new Xubuntu 15.04 in EFI mode. I installed gummiboot via sudo apt-get install gummiboot and activating sudo gummiboot install.
On my HP Notebook I have to enter the efi file as custom boot as described here: EFI\Boot\bootx64.efi
(Without switching to gummiboot, namely booting with EFI\ubuntu\grubx64.efi, works)
Unfortunately I get a kernel panic when trying to boot.

I have tried this on VMs and standalone machines and servers, and the problem is always the same. If I install Ubuntu 14.04 on a machine, and I update it to 14.04.1, the reboot takes a very long time (in the order of 10 minutes or so.) I removed the "quiet splash" on the Grub config, and then what I saw was that it was hanging on console stop/waiting, etc. for a long time. Note: I captured the problem on the VM, but I see the problem on standalone desktops and servers (14.04.1 installed on bare metal hardware). The problem is an issue that Ubuntu should fix.

The next message I see on screen is 50 seconds later, plymouth-upstart-bridge complaining, and the following event logged is a good 40 seconds beyond that message. Something very bad is going on.
Does anyone know what the issue is? Is this something you have fixed? If so, where did you start? I am hardly a Linux/Ubuntu noob, but 14.04 is just about the worst OS I have installed in years. It is definitely not LTS material.

Hardware is a Compaq Mini Notebook with HP HS2300 Broadband Wireless Module. UMTS provider and SIM card is Vodafone. Wireless WWAN is working well under Windows XP, but um my second System, UBUNTU 14.04 only WLAN has functionality. Does anybody know a software connecting the existing hardware to UBUNTU 14.04?
I had an intermittent issue (which resolves itself spontaneously, after using a different connection for a while) that caused Internet requests to fail, with one particular wireless network. After about 5 requests after associating with an AP, ping would report the error
ping: sendmsg: No buffer space available
just as in Wifi connected but no data transfer: "ping: sendmsg: No buffer space available".
In case it's relevant, I'm seeing with a Centrino Ultimate-N 6300 [8086:4238] wireless interface on a Thinkpad X201. Bug #836250 is possibly related.
While I can work around this issue, I was wondering: What does this error message mean? In particular, what buffer is it talking about?
