Why can't I save my sound settings in ubuntu xfce? Every time i log out and in the settings are not waht I want! Why is linux sound such a mess! There is alsa pulseaudio pipewire, no wonder it doesn't work! Please help a desperate user before I swicth back to Windows! Normally I want to use the sound icon (xfce4-pulseaudio-plugin) in the taskbar!

I have been trying to install Ubuntu server but to my frustration I end up on the local host login enter the details I set up during the beginning stages of the install and it just won’t accept them. The Login page isLogin Screen

I have redone the install 3-4 times checking that I am not mistyping passwords etc. i have also rebooted in recovery mode and when using passwd username it doesn't recognise the user, nor does it list a user with ls/home command from the root menu.

Now from recovery mode, when root menus is selected and enter is pressed I get this msg- Give root password for maintenance (or press CTRLD)

I’m trying this on an old AMD machine which was running Mint xcfe previously.

On Debian 13 and Fedora 43, my Canon G2770 is basically plug and play. I can just install sane and it's good to go. But when using Ubuntu, even though "sane-fins-scanner" detected a possible scanner (which is my Canon G2770), "scanimage -L" does not. Meanwhile on Debian and Fedora, "scanimage -L" is able to detect my Canon G2770. Running the install.sh provided by Canon website also doesn't help, it said installation successful, but I can't scangearmp2 also unable to find the scanner. The inkjet printer driver works fine (only downside is it cant wake up the printer automatically unlike on Windows). Manually adding usb vendor id and product id in the backend pixma.conf also did nothing. Oh, xsane also cant detect the scanner. Thank you for your help

I'm trying to dual boot Ubuntu 24.04.4 LTS alongside with Windows 11 on my laptop (AMD Ryzen AI9 365 + NVIDIA 5070). I kept having the issue of the pop up message "system program problem detected" right after the GRUB menu and cannot proceed any further, not even choosing the language. I've tried everything I found such as booting in safe graphics mode and decrypt the disk, but turns out nothing works. Can anyone help me out? Thanks!

I'm new to Kubuntu and I've been having an issue with one of my hard drives. I dual boot Kubuntu (25.10) and Windows 10 (whatever the latest version was before it went out of service), and I have a 1TB hard drive connected to my computer. I can access it on Windows, but on Kubuntu, it will not show up in Dolphin. My Windows drive's two partitions and my external hard drive appear (and my phone when connected) and can be mounted with a click, but my 1TB hard drive does not appear. I've been having this issue for all of my installations of Kubuntu (~4?) and I've been using Kubuntu for a few months at this point.

I tried sudo fdisk -l, and sda, sdb, sdc, and sdd appeared. I believe sda4 and sda5 (out of 6) are my Windows drive's partitions, while sdc2 (out of 2) is my Kubuntu drive, and sdd1 (out of 1) is my external drive. sda1, sda2, sda3, and sda4 appear to all be related to formatting and file recovery, while sdb and its 3 parts are my 1TB. Curiously, I think the lack of it is tied to the three error messages that appear after sdb's listing in fdisk, Partition 1/2/3 does not start on physical sector boundary. I also do not know if I can access this drive through Konsole, but I doubt it.

Is there a way to fix this issue without formatting my drive entirely? It isn't necessarily difficult to move files over to Linux on this drive, but I don't want to have duplicate files on that drive and my Kubuntu drive if there is a way around it. I want to keep this drive, since it has a lot of things I consider important that are hard to access again.

Please ask me if you need more information.

I am new to linux and just installed a new system on my computer in a dedicated partition. Everything is good except that I cannot get internet. The AX900 usb wifi adapter works fine with windows but linux does not see a wifi adapter. I downloaded the linux driver, followed the instructions, but still i get "no wifi adapter found." I think it sees the adapter as a flash drive, because it shows up in the left column. Any suggestions?

I am using RaspAP with default settings on a raspberry pi 5 with raspberry pi os bookworm

the only thing I changed in RaspAP is the name, password and country code, which I set to US (via RaspAP GUI)

I connected my ubuntu machine to it, and it connected perfectly.

I ran a ping google.com, and got no connection.

I pinged 8.8.8.8, and got a perfect connection

My phone connects to it perfectly, reporting no internet access, but when I go to google.com, it loads fine so I don't know what's up with that.

I checked NetworkManager GUI, and it showed DNS was set to auto

please tell me if you need any more info

This appears to be a recurring problem with no definitive answer: each time it comes up, a previous solution fails to work and a new answer is needed. I've lost track of how many questions and 'answers' I've read on this.

There must be many thousands of people who rely upon Virtualbox to run other Linux, and especially Windows, on Linux. And many will be on Ubuntu. So I don't understand why there isn't already a fix. I don't even know which update caused it. All of a sudden, VB can't start a virtual machine.

Would subscribing to Ubuntu Pro help?

Perhaps I got a 'phased' update, so most of the rest of you are oblivious of the problem?

NB, I've checked the BIOS: secure boot is DISABLED.

Below is some of what I've tried.

Edit 1, Edit 2, etc, are my responses to @heynnema's heroic efforts to find the solution for me. Our exchange (including help from @nobody) was moved by a moderator from Comments to Chat.

So, first try what it says in the error message:

I forgot to capture this before attempting to reinstall VB --- it's gone.

Tried to install a later version of VB direct from Oracle: failed.
Now I get: "Failed to acquire the VirtualBox COM object. The application will now terminate."

Yes, I know, I should have taken a more systematic approach. But it's difficult to write this on the machine you're trying to fix. Especially as some 'answers' have such enticing 'solutions'...

Synaptic used to install virtualbox 7.0.16-dfsg-2ubuntu1.1
Synaptic also chose and installed virtualbox-dkms and virtualbox-qt

Virtualbox will run, but I'm back to the original problem.

Edit 6

Synaptic search for "linux-headers-generic":
Looks like the 6.8 headers are still installed.

Uninstall?

From HWE kernels in Ubuntu docs: "HWE (Hardware Enablement) kernels are only enabled on Ubuntu long-term support (LTS) releases...By default, Ubuntu Desktop installations of 24.04 default to tracking the HWE stack.".

Edit 8

sudo apt purge virtualbox-7.2 Appears to remove 7.0, then says, "Package virtualbox-7.2 which provides virtualbox is not installed" ! Did I use the wrong command?

@heynnema: "Install virtualbox-source and virtualbox-modules using Synaptic"

Synaptic shows virtualbox-source but no virtualbox-modules.

Install via Synaptic of virtualbox-source:

E: virtualbox-dkms: installed virtualbox-dkms package post-installation script subprocess returned error exit status 10

But Synaptic does show virtualbox-source as installed.

In the description of virtualbox-source: "The source is placed under /usr/src, and after decompression it can be built to produce a virtualbox-modules-KVERS providing "virtualbox-modules" package." So I shall proceed with the source install...

After install, there is /usr/src/virtualbox.tar.bz2.

Extracting that creates /usr/src/modules/virtualbox/, which contains:

I have the following situation:

and need to resize my /boot partition at the very beginning of the drive. Now, unfortunately for some poor design when I installed Ubuntu I set my EFI partition in between the /boot and the root partition (/) of roughly 1TB.

My goal would be to shrink the / for ~650MB to add to the /boot; however, it appears this would necessarily pass through the EFI – which is something I'm aware should not be touched...

So, my question is it safe to do it or I should leave things as they are? I'm asking since I haven't allocated enough space for multiple updates at the same time, and I'm always forced to promptly removed unsed headers in order to update/upgrade the system. Thanks in advance!

Following along the steps below, this is where I'm at: and then

in the image above it appears I'm unable to edit the /boot/efi partition size...

I installed tree v 2.0.2 and in the terminal it displays the output properly but when I send to output to a .txt file it includes a bunch of NBSP ruining the display. It also happens when copying the terminal output.

This didn't happen before. Is this a new "feature" in version 2? How do I get it to display normal spaces instead of NBSP (which is for HTML)?

When I reinstalled the OS, I had only one, Ubuntu 22.04 Gnome desktop, option. I got used to MATE desktop. Therefore I installed MATE desktop too. Having two desktop environments, MATE & Gnome, how to switch between them? I cannot just remove Gnome as it affects LibreOffice. Do you have any suggestions?

On Friday 12th August, When trying to upgrade UbuntuStudio 20.04.4 to 22.04.1 by the network:

• download was done correctly
• Upgrading progession was correct.progression

After restarting:

• the message "mtd device must be supplied (device name is empty)" was displayederror message
• the login window doesn't appear, it stucks on the Ubuntustudio first display.ubuntustudio

Most of answer on the forum does not match to solve the issue.

What does mean this message "mtd device must be supplied (device name is empty)"?

Does Anyone have a solution to fix it?

I'm trying to update nodejs in a fresh installation of Ubuntu 22.04 in a VM.

When I run this:

nodejs --version

It outputs:

v12.22.9

I've seen in many places that to update Node to the latest version you execute these commands:

sudo npm cache clean -f
sudo npm install -g n
sudo n stable

When I do it it appears to work and states:

copying: node/16.16.0

However, when I nodejs --version again it still says v12.22.9

What am I doing wrong?

All I've found online tells me to do the above.

How can I update nodejs and have it update to the latest version?

I am currently using Ubuntu 22.04. I am trying to update libmutter-10-0 to version 42.2-0ubuntu1, but even after doing apt update and apt show mutter it shows:

Package: libmutter-10-0
Version: 42.0-3ubuntu2

I want to specifically update this package as there is a bug in the existing package. I am not sure how to update it as the package is very much available, if I see online here.

I'm using Ubuntu 20.04 on an HP da0077tx laptop and my headset's mic is not working on ubuntu. The same headset is working fine with other devices.

Audio Codec: Realtek ALC236

This Audio codec is not available on https://www.kernel.org/doc/html/latest/sound/hd-audio/models.html

I have my interviews next week and this issue can create a problem. Any help will be greatly appreciated.

I just upgraded from 18.04 to 20.04 (LTS), but now I can't play full-screen videos, whether from web browser of even VLC. Whenever I select full screen video. It creates a "picture in picture" effect in the upper left hand corner.

My machine is a Windows 10 dual boot, Acre Aspire 5. The output of sudo lshw -C video is:

Installed Ubuntu drivers:

The seems to be a bug in the 18.04 to 20.04 update that prevents the installation of some key drivers / software.

1. Using ubuntu-drivers devices to figure out what driver was missing and (recommended)...

2. Then using sudo ubuntu-drivers autoinstall

However I was able to immediately fix it using the same solution to the problem of not being able to install Shutter. The answer is in this post. Once I did this, I was able to finish the installation of the correct Nvidia driver, rebooted, and verified that it was installed in Softwatre & Updates.

After all this I still had the same problem. This is definitely an Ubuntu 20.04 bug. I had 18.04 on this machine with no problems. The result of sudo lshw -C video is still display: UNKNOWN

I went back and tried all of the suggested solutions by @hyttysmyrkky listed below, but none of them worked. The result of sudo lshw -C video is ALWAYS display: UNKNOWN. This includes using the -47 kernel and the 440.100 driver. None of the solutions worked. I still had the same picture in picture, full screen mode problem. In addition to this error, under 20.04 I had the following problems:

1. Unable to power off my machine from system menu. The screen goes dark, but the shutdown process would literally just hang no matter how long I waited, finally required a hard shutdown of holding down the power button.

2. The recognition of my intel WiFi card was hit or miss at boot time. If failed, I needed to reboot to in order get the WiFi working because restarting network-manager had zero effect

3. On a very annoyingly frequent basis, at boot my I would receive MOK messages (machine owner key) messages asking me to select boot systems even before grub. This would happen no matter how many times I had previously done the same thing.

4. Often the BIOS settings would revert to system defaults, completely bypassing grub and loading Windows 10, which created the need to:

   1. Reboot Windows in safe mode.

   2. Enter BIOS, change "SATA settings" to from "RAID with array" to "AHCI", Disable Fast Boot.

   3. Log back into Windows 10 turn off safe mode and reboot. (i.e. It was a giant waste of time)

I finally "fixed" the problem, by reverting back to 18.04 in which the "manually installed driver" option seems to work perfectly with the Nvidia driver. 20.04 is "eye-candy", but I will wait year before attempting to upgrade again. I just switched to the nvidia-driver-450-server on 18.04 and it too works perfectly.

I already installed pavucontrol and checked alsamixer for further verification, but I don't see an end to my problem. This is my Alsa Info

I already reinstalled alsa-pulseaudio, and force-realod.

Did

killall pulseaudio; rm -r ~/.config/pulse/* ; rm -r ~/.pulse*

pulseaudio -k

did

sudo apt-get remove --purge alsa-base pulseaudio

sudo apt-get install alsa-base pulseaudio

sudo apt-get install alsa-base pulseaudio

But none of the above solved the problem.

I'm trying to install Windows 10 alongside Ubuntu 18.04 because I want to try some games on my laptop, and then go back to Ubuntu.

I have two USB Flash Drives, one with Windows 10 and the other with Ubuntu 18.04.

These are the steps I've done after following some answers here on Ask Ubuntu:

1. Booted on Live Ubuntu, and shrank my 1TB HDD into a 500 GB NTFS partition with GParted;

2. Booted on my Windows 10 USB Flash (on UEFI) and installing Windows without deleting the partition or formatting it, just by pressing next ( I also tried deleting it and make a new one with Windows, but I encounter the same issue);

3. After install, it was directly booting into windows, probably installing other stuff, and this is the annoying part, Windows froze at

   Getting devices ready

   or something like this. I forced it to shut down and then .. continuing to step 4;

4. I booted again on my Live Ubuntu USB, and I have installed boot-repair, doing the recommended installation.

5. After installing boot-repair, I restarted my laptop, booted on Ubuntu OS redirecting me to GRUB Boot Loader, I selected Windows everything loaded then I got this error that Windows isn't installed properly and I have to restart and reinstall it.

I really don't know what to do any more, I deleted the NTFS partition and extended my ext4 partition, everything is normal now, but I really need Windows 10, I also need an answer on how to uninstall it and go back to normal.

This is one of the questions I was following, but it doesn't work for me: Install Windows 10 alongside Ubuntu 14.04

And this is the second question, and I was following the first and the second answer, except doing the mount /boot thing because I didn't know what to do exactly: How can I install Windows after I've installed Ubuntu?

EDIT : Here's the summary of boot-repair

I have 3 graphics cards installed on Ubuntu 16.04, and when I checked the PCI bus IDs by using three different commands:

1. nvidia-smi,
2. lspci | grep VGA
3. nvidia-settings

1. and 2) gave the same IDs, but 3) gave different IDs. It turned out that 3) was correct, which worked fine for another program while the others didn't. I was wondering why they gave different bus IDs in the first place.

Another problem was GPU IDs (0, 1, 2), where none of the GPU IDs reported were correct (commands 1)/2) and 3)), and I had to find the correct IDs by trying random combinations. Below are the results of nvidia-settings_GPU0, nvidia-settings_GPU01, and nvidia-settings_GPU2.

I'm struggling with the battery life of this laptop while running Lubuntu. In Windows 10 I'm able to get up to 9.5 hours of life in power save mode, but in Lubuntu a 100% charge lasts about 2.5 hours.

The laptop specs are:

• Nvidia GTX 1060 Max-Q
• Intel i7 7700hq (8 threads)

(Yeah, I know, I'm using Lubuntu in this machine. I just like Lubuntu very much)

I have display brightness at absolute minimum, tlp installed, powertop auto-tuned. When running prime-select query it returns intel so I'm supposedly using only the intel GPU. I even tried decreasing the maximum speed of the processor to 800Mhz with cpufreq frequency-set -u 800mhz. With all this settings the laptop lives at maximum something like 3 hours, but not more than that. Powertop reporst a discharge rate between 17W and 22W

However, when running plain Ubuntu 18.04 with gnome, in a live USB, with nothing installed, it drains so less battery, I get around 5 to 7 hours of estimated life, powertop reports a discharge rate of 11W or less.

I don't install Ubuntu simply because I really dislike Gnome take on UX (nautilus type-ahead removal, no shutdown without prompt option, etc), and I already have Lubuntu set up with all my necessities.

I tried another distros (Mint, Elementary, KDE Neon, Budgie) in Live USB but none of them consumed so little battery as Ubuntu did, they were around 10W and 15W. My theory is that since Dell supports Ubuntu in many of their laptops (this one at least you can get it with Ubuntu), they made some fine tunning with Canonical, that didn't go directly to Ubuntu derivatives like Lubuntu.

Also I have to note that powertop reports are really weird, saying that Display Backlight consumes up to 18W at times even though the display is at minimimum brightness, I think the nvidia drivers could be a possible cause (maybe the two gpus are working simultaneusly somehow?). Also it reports that the ethernet port is draining 1W o 2W when I'm using only wifi.

In the hardware side of things, I'm pretty sure my laptop is taking a lot of heat even when it is doing nothing (like 50°C), and I'm seeing the "fully charged" capacity of my battery going down in these days to 87% in less than two months.

Here is a powertop overview screenshot.

^{Click the image to enlarge it.}

Immediately after posting I rebooted the PC into the live CD to take the next powertop screenshot, this is right after the previous screenshot with almost the same amount of battery.

^{Click the image to enlarge it.}

I have burned OS image (.img) into a new SD card (Sandisk 16GB) use LibreELEC USB-SD creator tool on Ubuntu laptop. I assume I don't need to format SD card before writing. Then I tried browse SD card for files, but Ubuntu not able to show the contents of sd card. It only show space available on SD card. I tried also to browse SD card on Windows PC, but it don't recognized it, when click on SD card drive icon, Windows show alert that SD card first need be formatted. There is also listed volume 537 MB, it can't be opened, when try click to mount it, error message is displayed:

Unable to access "537 MB Volume"

I have VM Ubuntu 14.04 32bit running in VMware Workstation on Win 10.

I'm trying to set up the LXC container having its own IP address so I set the bridge interface in /etc/network/interfaces (tried static and dhcp):

 # interfaces(5) file used by ifup(8) and ifdown(8)
 auto lo   
 iface lo inet loopback 

 auto br0
 iface br0 inet dhcp
        bridge_ports eth0
        bridge_fd 0
        bridge_maxwait 0

But then I reboot it and have no internet on my host mashine Ubuntu.

--- 8.8.8.8 ping statistics ---
3 packets transmitted, 0 received, +3 errors, 100% packet loss, time 1999ms
pipe 3

But it can connect to the router and I can ssh it from my main OS (win 10)

I read all the similar posts but did not help. Any thoughts?

I am quite new to samba. I have an ldap server already setup with users. I am now setting up a new samba file server that they will be accessing through the ldap. Has anyone done this before? I am trying to follow a few guides online but they are confusing. Could someone give me a link or a guide of how to do this?

I'm trying to install TP-Link TL-WDN4800 Adapter with Ath9k under trusty. It should work just out of the box for windows and linux. On windows it works, but on ubuntu 14.04 (same computer) it doesn't. Sometimes I am able to connect, but then the internet is still veeeery slow.

I also changed the bandwidth of the router from "20/40 MHz (auto)" to "20 MHz". After that, I wasn't able to connect to the wlan at all. So I changed it back.

From all solutions I have read in the internet so far, nothing works.

Network manager can see the ssids of different networks, but fails to connect.

Just in case someone wants to point me to firmware-atheros:

E: Unable to locate package firmware-atheros

any help would be appreciated

EDIT:

I tried what was suggested:

$ cat /etc/modprobe.d/ath9k.conf 
  options ath9k nohwcrypt=1

But that did not help. So I tried to understand the output of dmesg

[ 1835.890681] wlan0: authenticate with f0:7d:68:83:97:82

Right after authentication, wlan is deauthenticated (what is reason=3?). I dn't know why.

EDIT2: I also tried this answer: sudo killall wpa_supplicant Oddly, that helped me to connect, but it didn't really work (veeery slow connection).

This time dmesg says:

UPDATE: With EDIMAX WLan Stick (8€) everything works out of the box. But with TP-Link TL-WDN4800 (35€) I have these problems...

As stated in the answer and comments the solution could be to remove TKIP. But I have a secondary router in repeater mode and that doesn't work with AES (don't know why). However, I don't see why removing TKIP would help, when connection is possible with different wlan adapters.

But still I'd love to get the TP-Link Wlan adapter to work under Ubuntu.

I run ubuntu 14.04 on a acer aspire 5742g and for some reason after a while my screen goes black and i get this error messages:

Jul  2 21:01:44 steven-pc kernel: [ 1591.975086] nouveau E[Xorg[1078]] failed to idle channel 0xcccc0000 [Xorg[1078]]

i found the error log in : /var/log/kern.log So far i know i haven't made any change to the kernel. Does anyone any idea what is wrong? if more information is required let me know.

I'm wondering if an alternative for DIALux lighting simulation software exists? It's really important for me as I replaced Autocad with Draftsight I still need DIALux without running it with Virtualbox to fully move to Ubuntu (finally!). Tried Wine, but it's not working. Google also doesn't know any software for my needs. Any electrical enineers on Ubuntu that can help me out?

Cheers

I have a home network with the following setup:

A QNAP NAS (has a DAAP server)
A server/media center with XBMC
2 laptops (Linux)
1 desktop (Linux)
Android phone
iPod

For a couple of years I haven't been able to find a good solution to my music sharing that allows for the following:

1. Centralized location for music
2. Centralized location for playlists (ie, define the playlist once, be able to play it everywhere)
3. Sync with mobile devices (Android and iPod)

My current setup is having my music on the NAS and either use an NFS share or the built in firefly DAAP to share it. This takes care of 1, but not of 2 and 3.

Do you have any suggestions or set-up ideas for how to achieve 2 and 3? Ideally I'd like to: - Create playlists on my linux laptop/desktops that could then be automatically added anywhere: on that laptop/desktop, on XBMC and iPod/android - Have an easy way of plugging and auto-syncing my iPod and android to either the complete music collection (iPod) or partial (android)

I'm running Ubuntu 11.10, and just signed up for Ubuntu One and Ubuntu One Music. Generally file sync is working fine, but music has been a complete failure so far. Here's what I'm looking at:

• After 24 hours, not a single mp3 or ogg file from my laptop has sync'd to the Cloud Music folder.
• I have 4 gigs of data used, which is definitely not enough to include music files. That's about the right amount for my docs and photos. With music, it should be more like 13 gigs.
• No music shows up on the Ubuntu One Music app on my phone, nor on the web view of my Ubuntu One Cloud folder
• I followed all the online instructions I could find. Basically, on my laptop, right click on the Music folder and select "Ubuntu One > Synchronize this folder"
• The Music folder now has a green check mark on it indicating its sync'd
• The Ubuntu One app on my laptop says "File Sync is up to date"
• I did provide credit card information, and on the Ubuntu One website "Music Streaming" is listed as one of my services.

So what am I doing wrong?
