i am experiencing lag in apps when disk activity high. i am not sure if this happen in every apps, but it usually happen in brave browser, steam, video games, file explorer.

the lag happen continuously, at first it doesn't lag/freeze, then the app freeze followed by not responding window, i can still interact with the not responding window. few moments later the app is working well again. moments later it lag again.

the lag happen only when disk activity high. in worst scenario, it makes my mouse completely freezing.

i am assuming it happen when there's intensive read/write activity (e.g. downloading and installing). is this normal in ubuntu?

i have tried change my browser to snap version, and turn off gpu acceleration. creating new sysctl.conf file sysctl.conf. updating bios to the latest version.

Sorry to bother you all again, I am currently using QCN9274(compex WLE7002E25) to test monitor mode, according to ‘iw phy’, it does support monitor mode. It appears I have successfully set it up, but I haven't been able to capture any data packages with tcpdump.

Does anyone know why?

I'm running Ubuntu 26.04 LTS, 64-bit, Linux 7.0.0-15-generic, gnome version 50. The device in question is the XP-Pen Artist 22R Pro. I use it as my sole monitor as well.

The issue I'm having is on start up, Ubuntu doesn't recognize the tablet. Though it will show that an unknown tablet has been plugged in. The cursor doesn't show up using the pen.

Unplug and plug back in? It suddenly recognizes the tablet and I can use the basic cursor function, but I can't draw or use it anything like a pen.

If I go to the driver/tablet application to configure, it completely stops working. There's no pen, no detection by Ubuntu, nothing.

I tried uninstalling and reinstalling the XP-Pen drivers, but it had no effect. Using the libwacom diagnostic tool provides the same information as above.

Before unplugging:

@DigitalStorm-D:~$ libwacom-list-local-devices
/dev/input/event22 is a tablet but not supported by libwacom
/dev/input/event8 is a tablet but not supported by libwacom
Failed to find any devices known to libwacom.

After unplugging and plugging back in:

   @DigitalStorm-D:~$ libwacom-list-local-devices
    devices:
      - name: 'XP-Pen Artist 22R Pro'
        bus: 'usb'

    @DigitalStorm-D:~$ 

Everything worked fine on the previous Ubuntu version I was using (24.04.4).

How do I get my tablet to work again?

kind of at my wits' end... after spending days and hours trying to get any kind of remote desktop / screen sharing whatever you want to call it working on my ubuntu system i gave up and fully wiped & reinstalled the system... and found myself in even worse shape than before. now ssh doesn't even work and it seems like an oddball situation.

btw love all the snarky answers from smarty pants folks saying stuff like "if auto-logon is enabled you can't screen share with ubuntu" or "if you are already logged on you can't remote desktop to ubuntu" why not?? this is basic functionality in windows and macos. and, if you really can't, why is there an option to supposedly do exactly this in the settings for desktop sharing? (separately, my "login details" for this section keep disappearing inexplicably... bug? feature?)

maybe related -- ssh error that i can't figure out. maybe i should turn it off and back on again like I used to do in 1983.

I have a problem with WiFi dongle based on RT2800 chip. It works fine on my Linux Mint PC dmesg looks like this:

On my laptop with Liveusb Lubuntu it keeps reconnecting in endless loop.

I've tried blacklisting rt2x00lib at boot menu adding blacklist=rt2x00lib or modprobe.blacklist=rt2x00usb but it doesn't make difference.

I have an Asus Zephyrus Duo SE GX551, on Ubuntu 26.04, and I am considering the pros and cons of installing asusctl. The main benefit that I see, is having access to all the function keys of my keyboard. The main concern, is how it will handle the power profiles. I don't know if there will be conflicts between packages.

asus-linux does not officially support Ubuntu, so I will have to get it though a third-party repository (Mitchell Augustin) or build it myself.

Please help me to decide what would be the best thing to do in this scenario.

I'm having trouble setting up Remote Desktop in Ubuntu 26.04. After starting Remote Desktop on port 3389 and entering my username and password, the remote desktop session launches (I want to keep the same session open at all times). After restarting the computer, I can’t connect to it remotely. I have to log into Remote Desktop locally again and unlock the settings by entering the root password.

Is there a solution so that this also works after a restart?

I have a ASUS TUF GAMING laptop with two separate nvme each 1TB. On first one windows 11 installed with bitlocker disabled. And on the second one I installed Ubuntu Raccoon. But during installation Ubuntu installer reported bitlocker detected. Anyhow installation finished without any problem. I did not used any encryption also. Just created a user to login. I have created a swap, efi and an ext4 partition. After login, I could not mount the ext4 partition as it prompts for a password!? By the way, I checked the disk and discovered a Microsoft reserved partition in front of queue which was strange. Any idea? Tks

I have a Surface Pro 6. I've upgraded to Ubuntu 26.04, but now it won't accept my old password at startup. How do I fix this?

Also instead of giving me the normal login UI, I get tiny little text prompts in top left corner.

I have multiple users with thumbnail and these are shown in login screen. For the administrator which was created during install it is set as well, but NOT showing in login. Privileges are fine (or at least the same as other).

Can someone advice why it's not shown?

I recently upgraded to Ubuntu 26.04 LTS, and I noticed a new icon on the Dash. It's in the system area. There's the WiFi icon, sound, the new icon that looks like a speedometer, and the battery. When I click on the speedometer I get the usual list of things, but there's no longer a speedometer.

What is this icon and what is it for?

Back in the 90s I remember being amazed at the 'dancing postage stamp' videos of the time. I now know that many of these dancing stamps were Cinepak videos. Can I use a modern FFmpeg under Ubuntu to recreate one of these early movies and make it as authentically '90s' as possible?

I made a list on the bash with all the packages installed on Ubuntu.

Trying to restore them to another computer also with Ubuntu, I receive an error message saying that they are not on database.

With this command I made the list:

dpkg --get-selections > list_packages.txt

Then I imported the selection list to the package manager with this command:

sudo dpkg --set-selections < list_packages.txt

Finally, I tried to install the packages with this command:

sudo apt-get dselect-upgrade

There, the message says: packages not in database.

Trying to install them on dissimilar hardware with the same Operating System, I acknowledge the solution.

I'm trying to change the cursor sensitivity on the login screen, however none of the approaches I could find online seem to work in Ubuntu 26.04. I am using the default setup with Wayland and GDM.

So far, I've tried using dconf as suggested by some article online (sudo -u gdm dbus-run-session dconf write /org/gnome/desktop/peripherals/mouse/speed -0.8), however this fails and returns...

unable to create directory '/var/lib/gdm3/.cache/dconf': Access denied.  dconf will not work properly.

Another approach that I could find was using sudo -u gdm dbus-launch gsettings set org.gnome.settings-daemon.plugins.mouse active true, however dbus-launch does not exist in my case.

Can somebody direct me to a method that works on recent versions? I'm quite new to Ubuntu and Linux in general and don't really know my way around. Thank you.

The microphone of my laptop Lenovo Ideapad 330 running Ubuntu 22.04 doesn't work, there is no hardware issue. May this be a driver problem?

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.

HDMI as an output option just doesn't show anymore, though video via HDMI works just fine.  After a month with no suggestions for fixes, about to give up on Ubuntu and try something else for this system.``

I have Ubuntu 24.04.1 LTS on a Dell XPS 9320 (not dual-boot). Since I upgraded from 22.04 last month, my internal speakers have not worked. In Settings, Sound Output lists "No Output Devices". I do get sound via USB devices (speakers or earbuds). I've tried many suggestions from many related questions (see below), but none have worked. Now I'm reaching out for help (please and thank you). From my reading of the related questions, here's relevant information for my case.

Based on remarks of V1del, a forum moderator at archlinux. I tried the following 4 commands to diagnose:

$ sudo fuser -v /dev/snd/*

                 USER        PID ACCESS COMMAND
/dev/snd/controlC0:  jim        2555 F.... wireplumber
/dev/snd/seq:        jim        2549 F.... pipewire


$ aplay -l

$ pactl list cards

pa_context_connect() failed: Connection refused

$ sudo pactl list sinks
Connection failure: Connection refused
pa_context_connect() failed: Connection refused

I guess the two "Connection failure" are a problem, but I don't know what they mean.

Based on my research the past few weeks, the following also seem relevant to diagnosing my problem.

$ lspci | grep -i audio
00:1f.3 Multimedia audio controller: Intel Corporation Alder Lake PCH-P High Definition Audio Controller (rev 01)

and

$ inxi -A
Audio:
  Device-1: Intel Alder Lake Imaging Signal Processor driver: N/A
  Device-2: Intel Alder Lake PCH-P High Definition Audio
    driver: sof-audio-pci-intel-tgl
  API: ALSA v: k6.8.0-48-generic status: kernel-api
  Server-1: PipeWire v: 1.0.5 status: active

I don't see a sound problem in that output (the Device-1 line makes sense, as my camera doesn't work (Cheese, Skype); but that is not my focus here). I do see a problem from the next command I tried

$ sudo dmesg | grep -i snd

When I google "SDW0-Capture: ASoC: error at snd_soc_link_prepare on SDW0-Capture: -61" I see many posts (often Archlinux) that talk about downgrading the kernel. I don't know what that is, and it sounds bad (like a duct-tape fix, a patch not a fix). But maybe useful to note my kernel:

$ uname -r
6.8.0-48-generic

Please note that pipewire seems fine:

I think wireplumber's only problem is with the camera:

Maybe this info about pipewire-pulse is relevant?

I got changes, but no fix, with the following:

$ systemctl --user restart wireplumber pipewire-pulse pipewire

In Settings (Sound Output), this turned "No Output Devices" to "Dummy Output" in the Output of Sound. It also changed the cards and sinks listings, as follows:

Thank you in advance to any kind soul who can help me restore my speaker sound. And I'd be happy to share more info if it would help ...

PS If it helps, here is a sampling I other questions I've looked at for help:

Fixing No Sound (Dummy Output) Issue in Ubuntu 24.04 From the top answer there, I used sudo gedit to create /etc/modprobe.d/audiofix.conf and put in the lines

options snd-hda-intel dmic_detect=0
options snd-hda-intel model=laptop-amic enable=yes

After rebooting, no change.

No sound output devices listed after upgrade from 21.10 to 22.04 looks relevant, but it is about pulseaudio and 24.04 uses pipewire.

Fixing No Sound (Dummy Output) Issue in Ubuntu 24.04 suggests to downgrade the kernel, but that sounds bad to me. And my sound problem is "No Output Devices", not "Dummy Output"

I see several unanswered questions that may be about the same as mine, with no speaker-sound in 24.04; e.g. lenovo M90a, Ubuntu 24.04, missing sound on speakers, earphones ok

In my case aplay lists a sound card, so my problem differs from many other dealing with no sound in 24.04, such as No sound after upgrade from Ubuntu 22.04 to Ubuntu 24.04.

No sound in internal Speakers in Ubuntu 24.04 sounded promising, but the fix there was to disable fast-boot in Windows (I don't have Windows).

=== Here's more info,

 tail "/etc/modprobe.d/alsa-base.conf"
    options snd-usb-usx2y index=-2
    # Ubuntu #62691, enable MPU for snd-cmipci
    options snd-cmipci mpu_port=0x330 fm_port=0x388
    # Keep snd-pcsp from being loaded as first soundcard
    options snd-pcsp index=-2
    # Keep snd-usb-audio from beeing loaded as first soundcard
    options snd-usb-audio index=-2
    # options snd-hda-intel model=auto -- tried & failed for audio 
     fix 27Oct2024
    # blacklist snd_soc_avs
    options snd-hda-intel model=dell-headset-multi

I updated my bios to the most recent (from 2.10 to 2.16.1) but that seems not to have affected anything.

video card seems to be Intel

$  lspci | grep VGA.

As suggested by @hynnema, I used Mainline to change kernels to 6.5.11 and added "options snd-hda-intel model=dell-headset-multi" to alsabase.conf and rebooted (kernel 6.5.11) but still No Output Devices in Sound Settings. But now pipewire has a problem:

I plan use Dell's system restore, but first I need to back up my data and my legacy software programs.

Does anyone know how to fix this high cpu usage by a firefox subprocess called RDD Process ... or as a temporary band-aid How can I disable "RDD Process" until it gets fixed on firefox ? as a loyal ff user since its "there be dragons" days I'd hate to stop using ff however new ff users will not put up with this ff bug

here is top showing this

This just started other day ... previously I have never seen RDD

and yes it did not help by resetting my local settings by issuing

        rm -rf ~/.mozilla
        rm -rf ~/.cache/mozilla

this is on a beefy desktop and this RDD Process was consistently using high cpu forever ... it was not a temp short lived cpu spike ... however after repeatedly killing firefox and relaunching the RDD did reappear across several such cycles ... as I write RDD Process is gone yet this entire sequence of events has repeated itself across past week or so

coincidentally with above RDD issue, youtube now sometimes fails to play a video upon clicking the video yet same video plays OK on other browsers like Vivaldi

Below answer does not solve this high cpu issue ... How can I disable "RDD Process" until it gets fixed ? I do not want a cpu core pegged all day as I continuously use firefox even when only viewing very well behaved sites like SO ... after killing ff all is OK until I try to watch a youtube video at which point cpu goes to 100% and stays pegged forever AND the youtube video fails to render

UPDATE ff hamburger menu -> Troubleshoot Mode -> Restart ... just to disable all addons afterwards the RDD issue goes away however I would never use ff without my addons so this is not a solution

Major fault of this RDD bug is that cpu usage increases each time I click on a youtube video in a different tab even though none of these videos plays ... the video just sits there not rendering any video after clicking on it AND this high cpu usage continues even after I click on a different tab say the tab for this SO question ... see new tab under this condition :

I cannot download file folders from iCloud drive and OneDrive to my computer. I can on Google Drive. Photos are fine and individual files but not file folders.

Is there a way without individually downloading each and every file?

I am trying to install Freetube in Ubuntu 22.04 armhf (Raspberry Pi image) running in a Surface RT.

Freetube only provides .deb files for amd64 and arm64 architectures. Flatpak stopped supporting armhf, and the armhf version of Freetube available on Flatpak is outdated (it does not load Youtube videos anymore, probably due to change of API).

Is there any way to install Freetube on armhf Ubuntu? How can I compile (or preferably cross-compile) Freetube?

I'm new to linux environment. I created a file s1.c in a folder named 'program' which is present in desktop. When I try to compile my code using "/program gcc s1.c " it's showing "gcc: error: s1.c: No such file or directory gcc: fatal error: no input files compilation terminated." What may be the problem

The height of title bar in GNOME is really wide. Is there a way to make it narrow without installing any extension or theme? Title bar of File manager and Terminal is wide and looks ugly. I love how narrow the title bar of Unity on Ubuntu was. I'm on Ubuntu 20.04 GNOME: 3.36.8

I was making mnt directory in home-directory and when I try delete it, I didn't realize my relative path was root(/). Eventually I deleted mnt directory in root... How can I restore /mnt? My file system is ext4.

I get it after updating in Synaptic Manager

I recently did a clean install of Ubuntu 17.04 from 16.10.

error message:-

W: Download is performed unsandboxed as root as file '/var/cache/apt/archives/partial/samba-libs_2%3a4.5.8+dfsg-0ubuntu0.17.04.1_i386.deb' couldn't be accessed by user '_apt'. - pkgAcquire::Run (13: Permission denied)

I've installed Ubuntu 16.04.1 LTS in VirtualBox and tried to change the time zone via timedatectl set-timezone Europe/Berlin as root user. Unfortunately, this didn't work and I got the output

Failed to set time zone: Access denied

I know about the option to manually remove the /etc/localtime link and create a new link to /usr/share/zoneinfo/Europe/Berlin, but this is not very practical and I don't understand why timedatectl does not work.

Further system information which might help:

$ ls -la /etc | grep localtime
lrwxrwxrwx 1 root    root       27 Feb 14 07:48 localtime -> /usr/share/zoneinfo/Etc/UTC
$ ls -la /usr/share/zoneinfo/Europe/ | grep Berlin
-rw-r--r-- 1 root root 2335 Dec  7 10:59 Berlin

EDIT: I noticed additional strange behavior. Although the Access denied error is thrown, the time zone is changed. And after a while it is set back to UTC :/

EDIT: I'm installing the system automatically using packer. This includes using a preseed file which includes the following lines:

d-i clock-setup/utc boolean true
d-i clock-setup/utc-auto boolean true
d-i time/zone string UTC

Removing the last line kind of solves the problem, but it leads to a question during the install process (the timezone is estimated and I should confirm by pressing "yes") which destroys the automation.

Hi I have a toshiba satellite laptop. I recently decided to replace my os which used to be Windows 10 with ubuntu, and used a USB key to store the Linux installation, plugged it in, successfully installed Ubuntu and erased windows(as it says). After the installation A message popped up telling my restart the computer in order to Start using the new os. After doing so I get his blank screen With the message:

Reboot and select proper boot device Or insert boot media in selected boot device and press a key Can't access anything now, btw I did enter to BIOS and set everything back On default after the installation of the Linux and it still doesn't work Can anybody tell me what can I do?
