locate is forgetting files in home folder that it will find after another updatedb https://askubuntu.com/questions/1568543/locate-is-forgetting-files-in-home-folder-that-it-will-find-after-another-update

I run locate for files in my home (/home/xxxx) directory that I know have existed for months; it can't find them, but shows files in other file systems like /boot, /bulk, /usr, /var.

I run sudo updatedb and it then finds them. A day or two (or week ...) later, and locate can't find other files in the home directory. Again, a sudo updatedb fixes it.

This has been happenening for months.

It was a fresh Ubuntu 25.10 install, and then upgraded to 26.04. Hardware is HP Victus 15 laptop with 2TB SSD.

Unable to update grub https://askubuntu.com/questions/1568542/unable-to-update-grub

I am trying to append the substring i915.enable_rc6=0 intel_idle.max_cstate=1 to grub. Without it my system will not boot up.

I have changed the line

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.enable_rc6=0 intel_idle.max_cstate=1"

In /etc/default/grub and run sudo update-grub but when I reboot. I attempt to reboot I get a black screen.

I have tried boot repair however there is no i915.enable_rc6=0 intel_idle.max_cstate=1 option.

I don't want to have to edit grub every time I start my machine. I'm running 24.04.4 LTS.

Updates that just won't take https://askubuntu.com/questions/1568539/updates-that-just-wont-take

For weeks now, I've been getting the same messages from Livepatch saying that an update is available. The following are the pop-ups (plus screenshots) that I see every single day.

Secure Boot dbx Configuration Update - Installed:

Screenshot 1

Update available - Secure Boot dbx Configuration Update (20250902 -> 20260402):

Screenshot 2

Unable to update "Secure Boot dbx Configuration Update": Device only supports version upgrades:

Screenshot 3

An update has been installed. A restart is required for it to take effect. (Only after trying to update it a second time once the system has fully booted.):

Screenshot 4

I've updated my firmware through Asus, using the Windows side of my machine to get the firmware update. I've checked drivers for my CPU and other hardware and all is up to date. Other than that, I'm out of ideas of possible firmware. Does anyone have any ideas about what could be causing this?

WSL on hp laptop 17-cp3005dx [closed] https://askubuntu.com/questions/1568535/wsl-on-hp-laptop-17-cp3005dx

Is any one currently running wsl on subject laptop and running Gnome Evolution? I used laptop laast summer for business trip as it is very light weigt. Was running evolution, nemo, firefox, lowriter without problems. Once back home, switch back to my Dell 7720. Getting ready for another trip and have had a huge problem getting thinhs working. Finally there with Edition Windows 11 Pro, Version 26H1, Installed on ‎7/‎10/‎2026, OS build 28000.2525, Experience Windows Feature Experience Pack 1000.26100.316.0, but had to drop back to Ubuntu 24.04 as 26.04 gave Webkit error messages that corrupted message text. No support from MS, hp. Used AI from MS copilot to work through enough of the bugs to get evolution, nemo, lo writer,and firefox working.

Ubuntu 24.04 LTS https://askubuntu.com/questions/1568532/ubuntu-24-04-lts

I just received a shipment of an HP Z2 Tower G1 Workstation Desktop with a NVIDIA RTX PRO 6000 GPU card. The unit shipped to my location with Ubuntu 24.04 Desktop. NVIDIA-SMI shows it has a 580+ series NVIDIA driver and CUDA 13.0. It appears the OEM Ubuntu Repo (or Packaging?) shipped from factory is "oem-stella-temujin-meta". My question is: How do I do Kernel, driver, CUDA, and other Ubuntu 24.04 software installation and updates without damaging the software install? Thank you.

Ubuntu does not return to GUI mode after updating to 24.04 from 22.04 https://askubuntu.com/questions/1568528/ubuntu-does-not-return-to-gui-mode-after-updating-to-24-04-from-22-04

Upgrade from dialog box: error message: some third-party entries in your ‘sources.list’ were disabled. You can re-enable after upgrading with ‘software-properties’ tool or your package manager.

Continue Y

Also during upgrade I was asked to Run ‘fwupdmgr get upgrades

The upgrade proceeded and left the laptop in the Terminal, so I ran: sudo apt-get clean && sudo apt-get autoremove && sudo apt reboot which resulted in an attempt to reboot to the GUI, but it failed and returned to Terminal mode:

Only getting default Apache page in Vagrant VM https://askubuntu.com/questions/1568526/only-getting-default-apache-page-in-vagrant-vm

This is one of several VMs I have, all the others work, but even deleting the "html" directory, I still get the default page, so it's presumably the fallback.

The /etc/hosts file has this: 192.168.56.9 newbe.test

The Vagrantfile looks like this:

Vagrant.configure('2') do |config|
  # Set Box
  config.vm.box = "bento/ubuntu-24.04"
  # Set hostname
  config.vm.hostname = "newbe"
  config.vm.define "newbe"

  # Prevent vagrant-vbguests from being auto updated, this is time consuming and causes version mismatch with host
  if Vagrant.has_plugin? "vagrant-vbguest"
    config.vbguest.no_install  = false
    config.vbguest.auto_update = false
    config.vbguest.no_remote   = true
  end

  # Enable vagrant-bindfs support, if the plugin is installed
  # see https://github.com/gael-ian/vagrant-bindfs for details
  if Vagrant.has_plugin?("vagrant-bindfs")
    # The bindfs option has one more option, and the /var/nfs
    # is where the the folder is synced then it binds it to the
    # guest_path after.
    #
    # Ubuntu 22.04 has UDP disabled for NFS mounts
    # https://discourse.ubuntu.com/t/jammy-jellyfish-release-notes/24668
    config.vm.synced_folder ".", "/var/nfs", type: "nfs", nfs_udp: false
    # config.vm.synced_folder ".", "/var/nfs", type: "nfs"

    # This uses uid and gid of the user that started vagrant.
    config.nfs.map_uid = Process.uid
    config.nfs.map_gid = Process.gid
    config.bindfs.bind_folder "/var/nfs", "/var/www",
      # perms: 'u=rwx:g=rwx:o=rwx',
      # perms: 'u=rwX:g=rD:o=rD',
      perms: 'u=rwX:g=rwD',
      u: 'vagrant',
      g: 'www-data',
      o: 'nonempty'
  else
    # Enable NFS file system
    config.vm.synced_folder ".", "/var/www", type: "nfs",  nfs_udp: false
    # This uses uid and gid of the user that started vagrant.
    config.nfs.map_uid = Process.uid
    config.nfs.map_gid = Process.gid
  end

  # This uses the vagrant-disksize support, if the plugin is installed
  if Vagrant.has_plugin?("vagrant-disksize")
    config.disksize.size = '20GB'
  end

  # Configure RAM
  config.vm.provider "libvirt" do |vb|
    # Customize the amount of memory on the VM:
    vb.memory = "4096"
    vb.cpus = 2
  end

  # Specify private network
  config.vm.network "private_network", ip: "192.168.56.9"
  # Port requires for postgres
  config.vm.network :forwarded_port, guest: 5432, host: 5430
#   config.vm.network :forwarded_port, guest: 80, host: 8080

end

It's essentially the same as other working VMs I have.

The provisioning is inherited and will be changed, but it's one step at a time. To provision we SSH in and go to /var/www/local and run ./bootstrap10.sh of which the relevant part looks like this (I apologize for it being a mess, as I said, it's inherited, I will be switching it to ansible):

kernel module build failure after kernel update to 7.0.0 https://askubuntu.com/questions/1568523/kernel-module-build-failure-after-kernel-update-to-7-0-0

A recent update seems to have broken kernel modules. The kernel was updated from 6.17.0-40 to 7.0.0-28 but then the modules fail to build and the machine remains on the older kernel. I noticed this yesterday and the problem remains today.

This is what I see when doing an apt upgrade:

Ask Ctrl+Alt+T to open Ptyxis instead of gnome-terminal https://askubuntu.com/questions/1568519/ask-ctrlaltt-to-open-ptyxis-instead-of-gnome-terminal

I have the new Terminal by Ptyxis and the old gnome-terminal both in my Ubuntu 26.04. When I push Ctrl+Alt+T the old gnome-terminal appears. How to switch to modern Terminal by Ptyxis? I can call Terminal by Ptyxis manually, but I want to use Ctrl+Alt+T, and I don't want to remove gnome-terminal.

I have tried this without success:

$ sudo update-alternatives --config x-terminal-emulator
[sudo: authenticate] Password:  
There are 2 choices for the alternative x-terminal-emulator (providing /usr/bin/x-terminal-emulator).

  Selection    Path                             Priority   Status
------------------------------------------------------------
* 0            /usr/bin/ptyxis                   40        auto mode
  1            /usr/bin/gnome-terminal.wrapper   40        manual mode
  2            /usr/bin/ptyxis                   40        manual mode

Press <enter> to keep the current choice[*], or type selection number:

Then pressed enter key. But Ctrl+Alt+T still calls old gnome-terminal.

System stuck on GNU grub after auto install drivers on 20th July 2026 [closed] https://askubuntu.com/questions/1568518/system-stuck-on-gnu-grub-after-auto-install-drivers-on-20th-july-2026

Mount and use 2nd SSD for primary storage https://askubuntu.com/questions/1568507/mount-and-use-2nd-ssd-for-primary-storage

I am a very recent convert to Ubuntu, as in just this weekend. I put together a new computer, and decided to make the jump from Windows 10 to Ubuntu. I've been trying to search for answers as I can and make it work, but I'm having some trouble with this one.

I've got a fresh install of Ubuntu 26.04. As a practice with previous computers, I put the OS on a small dedicated SSD and use a larger SSD for apps and general storage.

I've tried following a few guides on how to mount an additional drive and have the OS automatically mount the drive on startup, but I've been unsuccessful so far.

I have successfully formatted and partitioned the 2nd drive as vfat using GParted, and added a line to /etc/fstab for the new drive as instructed by an instructional here. The issue could be that the instructional is 14 years old, and the method has changed since then. Any help is appreciated.

Kernel 7.0.0-28-generic on Dell Latitude 7380 display issue: extremely dark https://askubuntu.com/questions/1568498/kernel-7-0-0-28-generic-on-dell-latitude-7380-display-issue-extremely-dark

Recently, on this Dell Latitude 7380, running Ubuntu 24.04.4 LTS with Wayland, the kernel updated from v. 6.17.0-40-generic to 7.0.0-28-generic. After rebooting the display became extremely dark, starting immediately after the selection of OS was made in grub. It was barely readable in a dimly lit room, and it also appeared to flicker slightly.

Rebooting and selecting kernel 6.17.0-40 from grub worked normally, with fully controllable brightness. Retesting both kernels gave consistent results. For now, I've changed the grub selection order so that 6.17.0-40 is the first, i.e., default entry. That kernel and its header also have been set on hold. However, I'd like to know what causes the issue, and if there is a workaround, or newer kernel in the pipeline that could be tested to see if the issue has been resolved.

The results of uname -a are as follows for the new and old kernels, respectively:

Linux <PC_NAME> 7.0.0-28-generic #28~24.04.1-Ubuntu SMP PREEMPT_DYNAMIC Wed Jul  1 15:50:57 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

Has kernel 7.0.0-28-generic dropped support for hardware in this older Dell? This issue is about a Linux kernel update. Nothing in BIOS has changed.

Clones of the Dell 7380 (only slightly individualized per user) had been installed on four other laptops: two HP's, a low-end Acer, and an old Toshiba. Those machines receive the same updates as the Dell, and got kernel 7.0 (and any Wayland drivers) through Ubuntu Hardware Enablement (HWE) stack. Those four machines operate well with the new kernel; no issue has been noted, so the issue is peculiar to the Dell 7380 Latitude and its internal graphics.

Is there a conflict with Wayland windowing system?

Is there a driver needed?

Any help would be appreciated.

grub-install: warning: efivarfs_set_variable: writing to fd 9 failed: Cannot allocate memory. while installing Ubuntu 26.04 https://askubuntu.com/questions/1568488/grub-install-warning-efivarfs-set-variable-writing-to-fd-9-failed-cannot-all

I was installing Ubuntu Desktop 26.04 onto my drive when an error came up saying something went wrong but it didn't know what. The logs showed errors like grub-install: warning: efivarfs_set_variable: writing to fd 9 failed: Cannot allocate memory.

My laptop is an Asus x1404za with 8GB of RAM, 128 GB of storage, and a 12th gen Intel Core i3. I've added an ax210 to it for my previous Linux installation.

I believe I have done everything right, although I am new to Linux.

Repeated corrupted files, but SMART reports no issues https://askubuntu.com/questions/1568481/repeated-corrupted-files-but-smart-reports-no-issues

I have a small server (Zotac ZBOX-AD06-U) running Ubuntu 24.04. Twice now it's had an entire series of corrupted files on the HDD. (This time it's affected apt such that apt --fix-broken install fails; I think a reinstall will be required regardless.) It'll hang at boot complaining that a manual fsck is needed, then give errors like "inode <inode id> seems to contain garbage". The SMART diagnostics aren't finding anything wrong.

Edit: A 7-hour memtest86 run found 0 errors.

  1. How can I tell if there's a hard drive problem doing this? What other troubleshooting can I do to try to narrow it down?

  2. What can I do to prevent it in the future?

SMART data is below. The short and long tests at 156xx hours was after this event, and I believe the two tests at the 86xx mark were last time this happened. (No telling how long it had inode errors between these two. It is very rarely rebooted.)

(Ubuntu 24.04.4 Desktop [Wayland]/Gnome 46.0/Linux 6.17.0) How do I rotate login screen portrait left? https://askubuntu.com/questions/1568079/ubuntu-24-04-4-desktop-wayland-gnome-46-0-linux-6-17-0-how-do-i-rotate-login

I have turned my monitor physically in portrait position. I adjusted Settings -> Displays so that the layout for my desktop is okay, but the login screen is still landscape.

I read that this problem could be fixed with following instructions:

sudo cp ~/.config/monitors.xml /var/lib/gdm3/.config/
sudo chown gdm:gdm /var/lib/gdm3/.config/monitors.xml
sudo systemctl restart gdm3

But to no avail, it just does not work. No matter if I reboot or even completely turn off and back on computer. The login screen remains in landscape position.

According to mutter documentation monitors.xml is read from /etc/xdg. Copied file there but it did not work either. This is clearly an issue that cannot be fixed with blind workarounds.

I edited /etc/xdg/monitors.xml so that there were different settings than in ~/.config/monitors.xml. After that some settings was applied in gdm process login screen, but not the rotation it just wont budge, that change had effects only in user process desktop. Is it so that mutter under gdm does not have same capabilities than under user process desktop? If so, this is just banging head on the wall.

Could someone please explain the architecture behind all this gdm/mutter/gnome-shell mess?

USB Audio with kubuntu 26.04 results in audio glitches https://askubuntu.com/questions/1567895/usb-audio-with-kubuntu-26-04-results-in-audio-glitches

i currently have highly annoying audio glitches when listening to music: apps tried:

  • Quodlibet
  • VLC
  • bashgst-launch-1.0 playbin uri=file:///home/stefan/…/Schiller__Atemlos/1__02__Schiller__Tiefblau.flac
  • ffplay 1__02__Schiller__Tiefblau.flac

that all with my USB Audio Interface (iBasso DC06).

(build in laptop speakers seem to work)

for me it sounds as if the USB bus is overloaded with data / the priority for the data is to low..

Best way to sync Google Drive on Ubuntu 26.04 LTS https://askubuntu.com/questions/1567829/best-way-to-sync-google-drive-on-ubuntu-26-04-lts

I need the best way to sync Google Drive on my Ubuntu LTS 26.04 with local cache that allows me to keep working for at least a day without any internet.

Requirements are similar to Google Drive for PC:

  1. Ability to work completely offline (not even internet to "mount" the drive first and then disconnect).
  2. Download and caching of files when they are accessed.

Open source solution -- IMPROVEMENTS NEEDED: rclone vfs local mount now mounts and runs on cache, all without internet as of 22-07-2026. The current code is posted as my answer, and will be updated as I improve certain hiccups (see answer) down the line.

What I have tried and fails:

  1. Nautilus doesn't support native Google Drive starting GNOME 50. https://www.omgubuntu.co.uk/2026/03/google-drive-not-working-nautilus-ubuntu-26-04

  2. Dolphin + Dolphin Plugins + Konqueror + KIO GDrive + KIO Admin: Can't even add the Google account on Dolphin. Page shows blank.

  3. rclone bisync fails randomly and repeatedly. --resyncing has destroyed my work multiple times now. I can provide the last used code if asked.

Live patch works excellently - it just shows a red ! mark on the Panel https://askubuntu.com/questions/1535390/live-patch-works-excellently-it-just-shows-a-red-mark-on-the-panel

Opening Live Patch does not show any error, so why is there a red "!" mark on the shield icon in the Panel? I am using Ubuntu 22.04. I just restarted, and there are no errors on apt/snap level. nor on dpkg. Is this normal?

Screen brightness is super low after upgrade to 24.04.1 LTS https://askubuntu.com/questions/1525553/screen-brightness-is-super-low-after-upgrade-to-24-04-1-lts

After upgrading from Ubuntu Desktop 22.04 LTS to Ubuntu Desktop 24.04.1 LTS, I found out one of monitors to have low brightness. I couldn't find any control to change the brightness and when I googled for solutions, nothing helped me. Here are some outputs:

xrandr | grep " connected" | cut -f1 -d " ":

DP-1

xrandr --output DP-1 --brightness 1 and xrandr --output HDMI-2 --brightness 1 does nothing.

I tried the hack with Brightness controller, editing grub, Secure Boot DISABLED.

I am more than welcome for any advice.

I have also had to do a fresh install of Ubuntu Desktop, because upgrade from Ubuntu 22.04 LTS failed.

Update with Hannu's response: After implementing the setdbr function I get:

martin@dell:~$ setdbr
Current displays, numbered:
     1  DP-1 connected 1920x1080+1920+0 (normal left inverted right x axis y axis) 510mm x 290mm
     2  HDMI-2 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 520mm x 290mm

And whatever I type, nothing changes. I tried setdbr 1 1.0, setdbr 2 1, setdrb 2 0, setdbr 1 0

UPDATE 2: I tried to turn on the night light and play with the intensity and both displays reacted. Thank to this I think the problem won't be Kernel-related and there is still some setting missing.

I am also missing the brightness slider in top right menu, maybe this could help? Top right menu

Having issues with Putty https://askubuntu.com/questions/1379116/having-issues-with-putty

First, I want to say that I have decided to make the switch completely to be a Linux user now. So what I am about to say very much well could be a user error issue.

I have installed PuTTY onto Ubuntu and the menu pulls up just fine. What I am trying to do is connect to my Oracle Virtual Machine, in this case I am trying to connect to the Kali Linux OS I have installed. Once I enter the IP address in the PuTTY menu, it closes out the application. Literally kills itself, and I am not sure why.

I started to do some experimenting with other IP addresses and server names and websites, with the same result. Not sure what gives but could use some help or better yet an alternative to PuTTY hoping for that SSH Application to work.

can't add key - keyserver timed out https://askubuntu.com/questions/757714/cant-add-key-keyserver-timed-out

I'm trying to install mongodb on ubuntu 15.10. While following this - Install Mongo 3.2 on Ubuntu 15.10 - i got the following error message: 

W: GPG error: http://repo.mongodb.org trusty/mongodb-org/3.2 Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY D68FA50FEA312927

So then I attempted to add the key like this:

Not sure what else to try. I'm currently looking other posts here on this site to see if this has been addressed.

EDIT 1:

Based on this post: Can't add repo keys

I tried to run the command : 

sudo gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys D68FA50FEA312927

and then retried: 

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys D68FA50FEA312927

But it's still failing.

How to make password show asterisks as I type it when running `sudo` command? https://askubuntu.com/questions/387757/how-to-make-password-show-asterisks-as-i-type-it-when-running-sudo-command

Is it possible to make the password visible as asterisks (or any other character) on using sudo command?

Currently, it does not display anything, thus making it difficult to count the number of keystrokes pressed..

Huawei e173s 3G USB dongle won't switch into modem mode https://askubuntu.com/questions/381970/huawei-e173s-3g-usb-dongle-wont-switch-into-modem-mode

Output of

is

Bus 003 Device 003: ID 12d1:1c0b Huawei Technologies Co., Ltd. E173s 3G broadband stick (modem off)

I've checked if usb_modeswitch is set up properly as per https://wiki.archlinux.org/index.php/Huawei_E173s. It is.

Enabled usb_modeswitch logging. The log output is below. Seems like the device is identified by usb_modeswitch, and the switch message is sent, but no response. At this point I'm thinking that either there's a problem with the dongle's firmware (but it works fine under Windows), or udev can't communicate with it for whatever reason.

--------------------------------
(end of usb_modeswitch output)

USB dir exists: /sys/bus/usb/devices/3-2
Warning: USB attribute "serial" not readable.

All done, exiting

UPDATE. Have set various delays. Quotation from http://www.draisberghof.de/usb_modeswitch/#trouble:

Annother way of influencing the kernel behaviour is the parameter "delay_use" of "usb-storage" which sets the time in seconds after plugging when the storage device will actually be used (and probably automounted). The default value is 5; this might affect the switching result under certain conditions. To change the default add in /etc/modprobe.conf:

options usb-storage delay_use=1 (or 10, or other)

With delay of 1-3, works sometimes. Sometimes doesn't.

UPDATE 2. After days of testing, I have an impression that it is not any particular delay setting which makes usb_modeswitch work, but changing this setting. Also I have a (very tentative) feeling that logging in/out and changing autologin settings somehow interferes with modeswitching.

How can I adjust the mouse scroll speed? https://askubuntu.com/questions/255890/how-can-i-adjust-the-mouse-scroll-speed

Additional Language in KDE https://askubuntu.com/questions/102828/additional-language-in-kde

I just installed the KDE desktop environment and I want to install an additional language (Urdu) in Unity 2D. I was using it but in KDE it seems difficult to do so. I got to know about some change, something in etc/x11/xkb/symbols but when I tried I couldn't find such a directory. Please help me on how to write Urdu in KDE.
