I am attempting to use an RTX Pro 6000 Blackwell graphics card on Ubuntu 24.04.

However, I am writing to inform you that persistent issues have occurred after installing the graphics driver.

1. When installing versions 570, 580, 590, or versions 570-server, 580-server, and 590-server, a black screen appears after the Ubuntu logo loading screen, and the system freezes.

2. When installing versions 570-open, 580-open, and 590-open, the system freezes at the Ubuntu logo loading screen.

Below are the methods I have tried to resolve this issue:

1. Updated the BIOS to the latest version.

2. Installed kernel 6.8.0 or 6.17.0.

3. Disabled "New features."

4. Disabled Wayland. 5. Please run the command sudo apt install linux-headers-$(uname -r) build-essential dkms to install it.

5. I proceeded as described in https://stackoverflow.com/questions/79928532/installation-of-graphics-drivers-for-rtx-pro-6000-blackwell-and-24-04-environmen/79928538#79928538.

This issue also occurs on Windows. If only the graphics driver is installed on Windows, a black screen appears intermittently, and the system freezes or reboots.

Also, to help you identify my problem, I am providing my computer specifications.

1. AMD 9950X3D

2. MSI MAG X870E

3. DDR5-6000-CL30

4. PX-2200

If anyone knows the cause of this problem, I would appreciate your help.

I was editing a file that I assume was originally created with MS Office power point. When I was done with my edits and saved the file, the LibreOffice added blue dots and a box with text "Responsible: Text" on every page. How do I remove them?

I'm not too technical so please don't eat me.
I had an identical machine HP 14s dq3xxx with absolutely no problem running 24.04.4
Except one coffee spill too many and it died.

New Laptop, Win 11, turned off Bit Locker, installed 24.04.4.
On installation I turned Windows Bitlocker off. Just like last time.
Only the hard drive has gone, the only drive is described as a "card reader".
Has anyone got any thoughts on what I've done?

Thanks. Paul

I am using Ubuntu 24.04. I'm afraid some hacker might have tampered with my repositories.

All I did was search for the name of a package that I would like to download in the App Center, and this message appeared:

The software is not from a trusted source.
Do not install this package unless you are sure it is safe to do so.  

It appears in all .deb packages from the official Ubuntu repositories.

The funny thing is that my default language in Ubuntu is Portuguese, so why did this message appear in English?

I did not install any unknown fonts from the repositories, and it's not snap

The message that appears when trying to install it is

The software is not from a trusted source.
Do not install this package unless you are sure it is safe to do so.

In summary: I find a program in the software center. I click to download it. The above message appears, and then it asks for a password to authenticate the installation.

The output of sudo apt update in the terminal is:

To add an application to my favorites or ensure the icon is visible in the GNOME Shell application dock, I need to enter the StartupWMClass value in the desktop file. Sometimes this is simple, such as recoll but other times it is long and complex such as com.transmissionbt.transmission_66306_105514770. When it is long and complex I would like to be able to copy it from the Looking Glass interface. However I am not sure how to do this. There is a clipboard icon next to the crosshairs (visual picker) icon in the upper-left corner but it does not appear to save any text to the clipboard. This copy function was found to be working in 2021, so I figure I must be doing something wrong. How can I copy the wmclass value for a window in Looking Glass?

I'm using the latest LTS version of Ubuntu (24.04).

I’m looking for a good alternative to Internet Download Manager (IDM) on Ubuntu.

I’ve already tried Xtreme Download Manager (XDM), and it works fine for normal downloads, but I’m having trouble when it comes to downloading videos from YouTube — sometimes it doesn’t detect videos at all or fails to download them.

So I’m wondering:

• What is the best download manager on Ubuntu that feels similar to IDM?

• Is there any tool that reliably supports downloading videos from YouTube?

• Should I stick with a download manager like XDM, or switch to something else (like command-line tools)?

I’d prefer something with:

• Good browser integration (especially Firefox)

• Stable video downloading support

• Easy-to-use interface (if possible)

Any recommendations or setups that worked well for you would be really helpful.

Thanks!

I know this question was asked 1000000n times and it was answered 1000000 times. Nevertheless none of these solutions works for me. I installed Ubuntu 24.04 as Virtual Machine in Hyper V on my laptop. Laptop has resolution: 3456x2160. I completed initial setup and everything works fine now. But I still cannot change resolution of the Virtual Machine higher than 2560x1600.

On Linux:

• I set: GRUB_CMDLINE_LINUX_DEFAULT = "quiet splash video="hyperv_fb:3456x2160" in grub
• I run: update-grub

On Windows:

• I run set-VMProcessor -VMName "name-of-my-machine" -ExposeVirtualizationExtensions $true
• I run Set-VM -VMName "name-of-my-machine" -EnhancedSessionTransportType HvSocket
• I run set-vmvideo -vmname "name-of-my-machine" -horizontalresolution:3456 -verticalresolution:2160 -ResolutionType Single

And still when I connect to this VM it's open with max resolution as 2560x1600. I imported this VM on my desktop machine with 4K monitor and I have the same result - max screen resolution of VM is 2560x1600.

I run virtual Ubuntu on the same laptop before using Hyper V. I don't remember exact version. Maybe it was 22. An I was able to use the full screen mode. But now it is limited by 2560x1600.

So is there any special solution for this issue for virtual Ubuntu 24.04 in Hyper V environment?

I connect to the internet at public sites, usually my local library, which involves a network login page.

My problem is that before that can happen, the network xfinity often hijacks the login process by connecting itself to my laptop.

How can I permanently ban xfinity network from connecting to me. I use Network Manager on Lubuntu 24.04

Until now, Snap was used in Ubuntu to install specific applications, such as Firefox, but those applications and snapd could be removed (and the applications could be replaced by packages, in some cases, such as those from Mozilla, or with Windows apps running in wine, such as 7-Zip).

Online, I've read that various components intrinsic to Ubuntu 26.04 are using snapd, and that it no longer can be removed simply. Is that the case, or is it feasible to remove snapd, still?

Is it possible to build a user-space apparmor profile? I have an Electron app, and a bunch of users that prefer installing their apps in their home rather than in the root. Unfortunately, running the Electron app requires an apparmor profile because of the sandbox, and I was not able to find a way to build such a profile in user-space, I necessarily have to install something in /etc.

Is it correct that it is basically impossible to install an Electron app without admin access on Ubuntu? :(

PS: The question is really to related to the ability to provide the app for people without admin access.

I have more than one WiFi adapter installed on my machine running Ubuntu 24.04. They're always shown in the same order in WiFi settings no matter which one is actually connected. See the picture below.

Is there a way to change the configuration so that the WiFi adapter that is connected to the WiFi network is displayed first in Settings?

On starting the Ubuntu 24.04 installation an almost unreadable message appears on the screen saying:

Firmware file b43/ucode30_mimi.fw not found. 
You must go to https://wireless.docs.kernel.org/en/latest/en/users/drivers/b43/developers.html#list-of-firmware 
  and download the correct firmware for this driver version. 
Please carefully read all instructions on this website.

There is a table on the mentioned page. In the column version of wl. wl I guess wireless are 12 numbers with links listed. They are links to download the driver I guess, however I don't have any information about the meaning of those numbers! On the following page, some Acer notebooks are mentioned, less Acer Aspire 5750!

In short I don't have a driver for the Broadcom wireless chip! At the "repair café" where the customer brought the laptop, I could install Ubuntu 24.04.02 without wireless, hence without internet of course! I took the laptop home and tried an completely new installation being connected to the internet by a LAN cable. This was worse! The installation failed completely telling me in the error message: "We are not sure what kind of error happened, try to install again!" Which of course doesn't work and the partially installed system is not bootable at all. Two kinds of sending the error report are provided. One "Send problem" which doesn't work, and a second one by: sudo ubuntu-bug ubuntu-desktop-boostrap, which doesn't work either.

Can someone tell me where to get this damned Broadcom driver, the correct one for the chip in this Aspire 5750 Notebook and I need to know whether I could place the driver on the USB stick which I used to do the Ubuntu installation?

I'm trying to run Ubuntu on VirtualBox (on Windows 11). I followed the instructions here https://ubuntu.com/tutorials/how-to-run-ubuntu-desktop-on-a-virtual-machine-using-virtualbox#1-overview

When I press "Start", I get to this GRUB boot menu screen giving me 4 options instead of the login screen shown in the tutorial. The top 2 options always result in this black screen.

If I press 'c', I get to this screen.

grub> _

I've seen posts saying what commands to run, but grub doesn't know those commands (e.g. sudo, update-initramfs, apt, get, install; as sudo update-initramfs -u -k version is suggested here)

Additional fixes I've tried: uninstalling and reinstalling VirtualBox, deleting and redownloading Ubuntu 22.04.

What's even more annoying is that I've tried pressing "expert" mode when setting up a new virtual machine, and now every time I press "new" I get stuck in [this][4] screen; there's no next/finish or cancel button.

The only thing I didn't follow in the tutorial is I limited the VM to 10 GB instead of the recommended 25 GB, but now I can't even try 25 GB because expert mode is stuck (even after uninstalling & reinstalling VirtualBox).

I have a web service running using systemd, this service runs by its own user, and I would like to execute some ExecStartPre commands but running as root user. So more in detail:

i.e /lib/systemd/system/webservice.service

[Unit]
Wants=network-online.target
After=network-online.target

[Service]
EnvironmentFile=/etc/default/web
Group=webuser
Type=simple
Restart=on-failure
WorkingDirectory=/usr/share/web
RuntimeDirectory=web
RuntimeDirectoryMode=0750
ExecStart=/usr/sbin/web --config=/etc/web/config.ini                               

[Install]
WantedBy=multi-user.target

and I would like to have a drop-in service where it fetches from a web-source the config.ini file

i.e /etc/systemd/system/web.service.d/local.conf

[Service]
PermissionsStartOnly=true
RestartSec=5
EnvironmentFile=/etc/environment
ExecStartPre=+/usr/bin/curl http://some.url --output /etc/web/config.ini 
ExecStartPre=+chown web:web /etc/web/config.ini  

The configuration above is not working since my service is freezing during the startup without any message in any log. Is there any way I can make something like that to work?

I'm on 19.10 (Eoan Ermine). Recently I let apt upgrade my kernel from 5.3.0-18-generic to 5.3.0-26-generic.

5.3.0-18-generic continues to work fine in both recovery and regular boot modes, however 5.3.0-18-generic fails to recover properly from suspend; the system is unresponsive even though the display manager is visible, the keyboard is unresponsive.

If I attempt to boot, however into 5.3.0-26 from any state I get this message (only visible using recovery mode) which ends in kernel panic.

5.3.0-18 continues to boot fine using either regular or recovery boot modes.

I do see the line about the syntax error from the suspend file, but I'm inclined to assume that's unrelated to the more serious kernel panic.

I installed Ubuntu 18.10 on my HP EliteBook x360 1030 G3 and can't get all fn-combinations to work.

What works: Volume up/down, Mute, Airplane mode What not works: Brightness up/down, Microphone mute

The often stated kernel parameters as listed here aren't resolving this issue.

Trying the command showkey -k revealed some strange behaviour: For all combinations not working a press and release with the same keycode (465) is generated. The other combinations result in different codes.

When running xev or acpi_listen no event is listed for the malfunctioning combinations.

Would be great if there is a way to get any reaction for this key combinations.

My computer wasn’t connecting to my Ethernet earlier, so I tried resetting it. When doing so it reset instantaneously which is weird for my computer. I tried shutting down, but it just went right back on. I tried force restarting it with my reset button and it went off. When turning back on, it stayed at a black screen for a long time. I held down my power button to shut it down forcefully. Now when I turned it on it is stuck at a kernel panic.

I have tried booting into safe mode to no avail. Reinstalling is not an option.

I’m using Xubuntu 16.04.

I don't have a clue why is happening:

• The only error on the XOrg logs is (EE) open /dev/fb0: Permission denied ($ grep EE ~/.local/share/xorg/Xorg.*)
• Also, on display settings, there is no "Detect Displays" button, like in Ubuntu 17.10.
• I tried installing latest drivers from https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers
• I tried with different cables and monitors.
• Googling, I didn't find any recent response that fit with my problem.
• Tested cable and monitor with other laptop and working without any issue.
• Tested with Live USB and working without issues.
• Both monitor working in the Login.
• Is the module i915 the right one for an i7-4870HQ (Haswell microarch)?

To be honest, I don't know where to start to search.

Note: In the office is working as usual with two monitors!! It is like if it's memorizing the configuration. But las week dual monitor was working at home. What did change? How to fix it?

My laptop has an rtl8723be WiFi card. The trouble started when I tried to install the latest drivers WiFi version. The spotted problem is that when my my laptop is being connected to a WiFi network, a process named systemd-journal automatically starts running in the background creating huge log files like 60 GB, but when I run sudo modprobe -rv rtl8723be both the WiFi and the process turn off. I found the created files and deleted them, but the question is, what can I do in order to use WiFi without getting a kernel panic. Currently I have turn off the WiFi and I am using Ethernet.

I was trying to fresh install Ubuntu 16.04 on a Dell 3521. Previously I was using 15.04. The system was getting slow ,so I wanted to install fresh. I deleted the /, /boot, /swap and recreated them. There are still two other drives (ext2).

While installing I did select encrypt /home and continue in UEFI mode. The process was terminated after

Now I am unable to boot. I tried both Install Ubuntu and Try without installing using a USB, but it is showing error kernel panic.

I have a file.img file that I want to convert to file.iso.

The tool ccd2iso does not seem to work for this task:

Unrecognized sector mode (0) at sector 0!

I ensured that the img file is not corrupted.

after installing Ubuntu 14.04 software center downloaded 540MB. when restarted to apply changes it is taking too long. I've waited for more than two hours process is going on like in the image. it is not continuous. There is a break after every line for 30-60 seconds.

Now I cannot update my OS. How much time do I need to stay after restarting? please help me in this regard.

my specifications: 4GB ddr3 RAM. 500GB HDD.

It is a kernel panic and it continues.

I can use my laptop only in previous versions. Please show me how to have a stable update so that I can use my laptop normally.

I am exporting an Inkscape vector graphic (.SVG) to the PDF format required by the digital printers but one of the fonts used (namely Futura BdCn BT) is not formatting correctly in the exported PDF whilst everything else works fine. I have done pre-press (for too many years) albeit on Macs/MS-Coreldraw using the same techniques, but a few years ago moved over completely to Ubuntu for all my computing needs; now needing some new business cards, stumbled on this error and cannot work out why it's occurring. The design is simply text with a single QR graphic on it and that works fine, except for the Futura BdCn BT not formatting correctly and coming out more 'fat' and bold as opposed to the slim Futura BdCn BT style.

I'm using Ubuntu 14.10 with the 0.48 Inkscape install, but prior to next trying an Inkscape upgrade, has anyone experienced this issue and how do you overcome it? Failing that, anyone have a solution for the pre-press PDF requirement.

Thanks in advance.

I am trying to install Ubuntu 14.04 on my work computer. First I had to active VT in the BIOS and now I get this kernel panic error and I can't fix it:

The computer uses a Core i3-4130 CPU with 8GB of brand new RAM.

I already tried setting the processor to Intel VT-x or AMD-v in the Virtualization engine options, but I got the same error.

I want good scientific calculator which can calculate the roots of any quadratic equation just by entering the quadratic equation

first of all is any app like those there in ubuntu software centre??

I have a quick question maybe someone could help me with.

I downloaded a few apps and ISO's from source forge today and they seemed to have disappeared. They weren't in the default down load folder or in the Firefox download cache.

So anyway, I started clicking around in my files trying to locate them and I came across a file string that I hadn't seen before. /var/spool/postfix/etc/ssl/certs. And in it, I found all these ssl CA and Root CA certificates (maybe 200 to 300 of them). I can open them and see pub. key.

Algorithm, Signature (huge table of numbers) and a bunch of other info that seems sensitive. I know very little about encryption and secure sockets, so I was wondering if this is a normal place to find such items.

By the way I don’t use local mail service on the machine. So I don't Know why anything would be in there. Thank You. B

I am accessing an Ubuntu 10.04.2 LTS server via SSH from OSX. Recently the colors stopped working. I think it happened while I was installing/troubleshooting RVM, but I am not positive.

In .bashrc I uncommeneted force_color_prompt=yes, and when I run env | grep TERM I get TERM=xterm-color. But still no colors.

Any ideas? Thanks!

I have several instances of terminals running in my working environment, what I would like is to set a specific title for each one, in order to have a clear idea what purpose the specific terminal serves i.e. Apache, editing_ini, postgres etc...

Of course from the command line.
