I forgot my password for Ubuntu on my Samsung laptop. From (Recovery menu, Drop to root shell prompt, Give root password for maintenance) I've tried unsuccessfully: mount -o rw,remount /.
I am running Ubuntu 26.04 and want to share my clipboard with a VirtualBox 7.2.6 host.
I have installed all apt updates and snap refreshes.
I also installed the VirtualBox 7.2.6 client additions.
I tried cutting and pasting text from host to client and client to host and it does not work.
Is anyone running Ubuntu 26.04 and is able to copy-and-paste text from host to VirtualBox client?
How do you do that?
I'm using the following command to update HTML files
sed -e "s/SRC=\([A-Za-z0-9.\/_-]*\)/SRC=\"\1\" /gi"
I'm having trouble adding + and & to the above as valid filename/path characters. My best understanding is that these special characters need to be escaped, like so:
sed -e "s/SRC=\([A-Za-z0-9.\/_-\+\&]*\)/SRC=\"\1\" /gi"
but I suspect the added bash command line complexity has me stimied. TIA.
After installing Kubuntu 26.04 on my Slim 3 with Ryzen 7 7735HS, i noticed that sometimes my machine wont wake up from suspension, it acts like it is suspended, with external devices RGB off and with the power button blinking as it should. but when trying to resume by pressing any key or pressing the power button once, it wont wake up. I need to hold the power button until it turns off and then press it once to turn on again, and when this happens the battery protection mode always turns off and i need to turn it back on. I made a post about that here before, and a suggestion was made by someone for me to update my BIOS. I did it through a HirensBoot formated with ventoy, since it was my only option (i dont have windows and the only installation media available is an .exe file on the lenovo site). Was pretty confident that this was going to solve my problem, but it persisted and now, a few days after the update, my computer wont turn off most of the time. In that state, everything looks exactly like when my computer is powered off: Black screen, no rgb in external devices, but the power button glows white as it does when the computer is on. And my battery drains somewhat fast (drained about 80 percent after one night and one morning). Can someone please help me with those problems??
My professional laptop Dell Precision is under Noble 24.04 installed after delivery (delivered under Jammy).
I am french so I used fr (bepo) keyboard layout.
I stay with X11 to use Gimp, have no issue with web-conferencing app …
I still had kernel update (6.17.0-22) that switched me under wayland and qwerty keyboard layout,
I run in CLI:
setxkbmap fr bepo
that returns me:
WARNING: Running setxkbmap against an Xwayland server,
I swithed back to kernel 6.17.0-20 and X11.
After a first use, my laptop locked up after being idle for a while, then when I entered my password, I can't connect… it switched to qwerty. I also connect to the docking station to have external screen, but it stayed black, no external screen detected in display parameters. I had no more wifi connection, I should connect by cable.
I didn't find under grub connection to switch back to X11, so I switched in /etc/gdm3/custom.conf the WaylandEnable=false, but if I switch with success to X11, I still had no wifi, external screen.
Tried to redo the kernel installation, but fails using sudo apt upgrade -y. Had to rewrite initrd configuration before update-grub. Could you kindly check right now.
I've recently updated my system through the "Software Updater" app.
After restarting the system the screen resolution was wrong, much smaller than expected and if I look among the Settings I am not able to choose any other screen resolution.
Previously, I was able to solve it by playing around with the settings in the "Software & Updates" app (NB: which is different from "Software Updater").
Apparently, Canonical has decided to remove it from newest versions of Ubuntu (see more: https://www.omgubuntu.co.uk/2026/02/ubuntu-26-04-drops-software-and-updates-gui).

After looking around on the internet I followed some instructions:

After rebooting the system, the problem persists
What else can I do to solve the problem?
Environment:
Red Hat OpenStack Platform 17.1 (OVN networking) Compute host: Broadcom NIC (bnxt_en driver), 25 GbE bonded uplinks Same host, same tenant network, same flavor — only the guest image differs
Problem: A VM booted from an Ubuntu cloud image gets only ~200-300 Mbps upload/download. A VM booted from a RHEL image on the same host and network gets ~8 Gbps. Roughly a 30x difference attributable solely to the guest image. Testing method: Multi-stream iperf3 (8 parallel streams), VM-to-VM. Platform capacity independently confirmed at multi-Gbps, so this is isolated to the Ubuntu guest. What I've already verified:
Network QoS policy allows 2 Gbps+ (not the limit) Physical NIC is 25 GbE with clean counters MTU is correct (1500 guest / geneve overlay) RHEL guest on the same host hits ~8 Gbps, so host/fabric is fine.
Question: What differs in the Ubuntu cloud image's default network configuration (virtio multiqueue, offload settings, driver/kernel) that would cause this large a throughput gap versus RHEL on the same virtio-net platform?
Could the issue be something other than apparmor? A 24.04 system on the same network gives the same DENIED type messages but, the print to PDF happens. On 26.04, I see no output file at all when the print is coming from another system on the LAN
Using 26.04. CUPS print to PDF is working when the originator of the file is on the 26.04 system. The CUPS PDF print is shared with other systems in my local area network. At attempt print to PDF from an XP system in my local area network is failing. The system log contains a few lines such as this
2026-07-16T21:23:36.032922-05:00 localhost kernel: audit: type=1400 audit(1784255016.031:150402): apparmor="DENIED" operation="connect" class="file" profile="/usr/lib/cups/backend/cups-pdf" name="/run/samba/winbindd/pipe" pid=1158626 comm="cups-pdf" requested_mask="wr" denied_mask="wr" fsuid=0 ouid=0
Due to the presence of an XP system in my local area network, winbind is installed.
I've got rid of the above message from syslog by disabling apparmor with regard to cupsd (I think) but messages about dbus-daemon persist, an example is:
2026-07-17T10:06:37.333138-05:00 localhost kernel: audit: type=1107 audit(1784300797.331:152868): pid=1310 uid=995 auid=4294967295 ses=4294967295 subj=unconfined msg='apparmor="DENIED" operation="dbus_signal" bus="system" path="/com/redhat/PrinterSpooler" interface="com.redhat.PrinterSpooler" member="JobQueuedLocal" name=":1.8991" mask="receive" pid=349875 label="unconfined" peer_pid=1168372 peer_label="/usr/sbin/cupsd" peer_info="No such file or directory"
What do I need to change so that this works?
I installed Ubuntu 24.04 on a PC that has a USB WiFi dongle. It uses the chipset
idVendor 0xa69c
idProduct 0x8d80
Ubuntu doesn't recognize it. It has an .exe driver in a partition inside the dongle.
I had to connect my PC through eth and install.
sudo apt install -y git build-essential dkms linux-headers-$(uname -r)
and then run a script that I downloaded from https://github.com/shenmintao/aic8800d80/blob/main/INSTALL_SCRIPT.md
I was wondering if you guys could add this driver in the next update.
Chromebook in question: HP Chromebook x2 - touchscreen tablet with detachable keyboard.
Following the guides on mrchromebox.tech, I was able to get Lubuntu installed. Everything is working great except the trackpad. The cursor "warps" to the corresponding location on the screen to wherever I touch the touchpad (if I touch the top left of the touchpad the cursor instantly moves to the top left of the screen) and it constantly clicks and drags as I move my finger around the touchpad.
Touchpad in question:
I haven't used Linux in a decade or so so you'll have to excuse my ignorance. I used AI to give some bash commands for the below info. Let me know if I can provide more info.

System info:
Up until couple of days ago, everything was honky-dory. Went thru few firmware updates using firmware-updater GUI, and reboot every time I was asked to earlier today. I am not sure if what is happening is tied to that action.
I'm on Version 24.04
When I open nutil;us, all I see is a snap folder.
When I launch terminal, I can see all my files but in nautilus only a snap folder.
Any other link from the left panel, i.e., downloads, Documents, Music etc is giving me "Oops, something went wrong" message but displaying the correct path under it and said path is accessible and has the ownership of my user all throughout as I see it in my terminal. I used to be a Unix/Linux sysadmin back in the day but later switched to infosec and retired few years back. I can still find my way around bash but these GUI crap is all nonsense to me.
I am getting this error message now when I try to use Steam,
Steam now requires user namespaces to be enabled.
This requirement is the same as for Flatpak, which has more detailed information available: https://github.com/flatpak/flatpak/wiki/User-namespace-requirements
The documentation on GitHub may as well be in Martian.
I am running Ubuntu 24.04.4 LTS, all up to date, on a Lenovo V15 G4 ABP. Steam is installed via the App Center.

I write that here because I found the answer after looking for it.
I migrated from Ubuntu 25.10 to 26.04 just recently, and noticed quite quickly that the sound was crackling. At first I thought my jack was badly plugged, but I could not solve it physically. I searched several things.

This subject has been around for a while but I think it needs an update. I have experienced the issue several times before and I have always been able to fix it by reinstalling the driver. However with a recent system update, no such luck.
My system is Ubuntu 22.04 with Kernel: 6.8.0-124-generic x86_64 bits, and a dual head graphics card NVIDIA GeForce GT 710. The correct driver is nvidia-driver-470.
The update installed the nvidia driver 535 which doesn't work. Attempts to install the 470 driver using apt install ignores the 470 driver and installs the 535 instead. I understand that this is because the 470 driver is no longer supported even though it is a common piece of hardware and is still available.
I was fortunate to discover after much gnashing of teeth that I could force the system to use a generic driver (Nouveau) by:
sudo apt purge "*nvidia*"
sudo apt autoremove --purge
sudo reboot
Then by going to Additional Drivers I found I could now select nvidia-driver-470 and install. Now things work again!
So my question is what exactly is going on? Also is it going to be safe to install future updates without breaking my system?
I have a number of hosts running Ubuntu in a lab managed by ansible. Ansible is used to upgrade and install specific deb and apt packages.
I've just upgraded one to 26.04 LTS. The upgrade caused a problem with ansible, triggered by the transition to sudo-rs.
How can I specify for a specific machine a different sudo executable; in this case, /usr/bin/sudo.ws?
I'm on Ubuntu 24.04, I have installed rhvoice and speech-dispatcher, and this works fine from the command line.
My use case is that, as a writer, I want to be able to get the machine to read my text aloud to help check it. I used to use an online service but it's really expensive. I don't need Orca because I am not visually impaired and it would be overkill.
I write with Scrivener on WINE, so that's not going to integrate easily. I have tried getting LibreOffice to talk using the Read-Text extension but that's not working either (I have queried that on the LO forums because it's doing something truly weird).
My ideal would be being able to slap the text (a chapter at a time) into a text editor (for example) and have it read back (pausing would be great but a paragraph at a time would be acceptable).
So does anyone have any idea what I could use? Am I going the wrong way using speech-dispatcher even though standard APIs are good, right?
The speech output doesn't need to sound natural, in some ways it's better if it isn't for my purposes.

After putting core.editor=vim to git's config is there a way to force git to launch vim with .vimrc other than $HOME/.vimrc? I mean I would like to have different settings for my day-to-day vim (which is $HOME/.vimrc) and other one for git tasks.
One can create aliases for all git commands (like git commit, git difftool) invoking vim. These aliases would, for example, launch external bash script that prepares everything, but it's not the way I would like to go for. Something I have in mind is:
~/.gitconfigIs there something like that?

How can I make Thunderbird to pin selected emails to stay always on top?
I can't find this feature in Thunderbird, there is a pin icon but it looks like it only "keeps the filtering when changing folders", whose function is not too clear to me. Also, suggestions on this (and possibly other) add-ons are welcome.
Klipper is frequently causing the system to hang on copy/paste actions. This is indicated by my taskbar being non-interactive on copy/paste. This will usually last for 10-30 seconds, or I will restart plasma through the terminal.
How do I disable/remove Klipper?

Ubuntu 18.04 LTS don't boot. I either get stuck on a blank purple screen, or right now, a blank purple screen flashes before going to a blank black screen. I got this laptop in August and still haven't figured out how to fix this. Replacing "quiet splash" with "nomodeset" or booting in recovery mode followed by safe graphics mode does allow it to boot, but then there are issues with display resolution which are bad enough to make certain windows unnavigable.
This problem has been posted and solved elsewhere, however they don't work for me or involve a Nvidia graphics cards which my laptop does not have. I have upgraded BIOS twice and neither time solved the problem. Entering dis_ucode_lds does nothing.
My Ubuntu 16.10 uses i915 driver. For some reasons I have troubles with it. So I want to force X to use VESA.
I tried:
blacklist i915 in /etc/modprobe.d/blacklist.conf. Then sudo update-initramfs -u. Doesn't work.
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash modprobe.blacklist=i915" in /etc/default/grub. Then update-grub2. Doesn't work
Added new file 20-foo.conf in /usr/etc/X11/xorg.conf.d with content:
Section "Device"
Identifier "Configured Video Device"
Driver "vesa"
EndSection
Doesn't work.
Guys, how on the Earth one could make an OS that requires such an effort just to switch video driver? Maybe I'm doing something wrong?
Is there any macro recorders for ubuntu? I want a program that i could assign a key to do a recorded mouse movement and keyboard typing. Thanks

Trying to run a game & the game opens the closes right away & in the terminal it says "libEGL warning: DRI2: failed to authenticate"
I have searched for weeks trying to fix the problem. All I found is
Anyone know how to fix this, Its driving me nuts. I have tried Nouveau drivers and I get even more libEGL warning errors
I am running Ubuntu 14.04
I figured out my problem guys. I had to downlowd eclipse, and it ran through that. sudo apt-get install eclipse Sorry about my lack of info. :)
I was looking at this question and I wondered if the following could be done from terminal. I did it in python, just want to see if it could be done from terminal, bash scripting or whatever.
Suppose I have a file that looks like so:
2,4,5,14,9
40,3,5,10,1
could it be sorted like so, by rows (lines)
2,4,5,9,14
1,3,5,10,40
or is it too complicated? I did it using python, I just want to know if it could be done so next time I might not use python. What I have done, is creating lists and sorting them.
